Scientific basis for the therapeutic use of Withania somnifera (ashwagandha): a review.

Abstract: OBJECTIVE: The objective of this paper is to review the literature regarding Withania somnifera (ashwagandha, WS) a commonly used herb in Ayurvedic medicine. Specifically, the literature was reviewed for articles pertaining to chemical properties, therapeutic benefits, and toxicity. DESIGN: This review is in a narrative format and consists of all publications relevant to ashwagandha that were identified by the authors through a systematic search of major computerized medical databases; no statistical pooling of results or evaluation of the quality of the studies was performed due to the widely different methods employed by each study. RESULTS: Studies indicate ashwagandha possesses anti-inflammatory, antitumor, antistress, antioxidant, immunomodulatory, hemopoetic, and rejuvenating properties. It also appears to exert a positive influence on the endocrine, cardiopulmonary, and central nervous systems. The mechanisms of action for these properties are not fully understood. Toxicity studies reveal that ashwagandha appears to be a safe compound. CONCLUSION: Preliminary studies have found various constituents of ashwagandha exhibit a variety of therapeutic effects with little or no associated toxicity. These results are very encouraging and indicate this herb should be studied more extensively to confirm these results and reveal other potential therapeutic effects. Clinical trials using ashwagandha for a variety of conditions should also be conducted. (Altern Med Rev 2000;5(4) 334-346)

The use of mushroom glucans and proteoglycans in cancer treatment.

Abstract: Immunoceuticals can be considered as substances having immunotherapeutic efficacy when taken orally. More than 50 mushroom species have yielded potential immunoceuticals that exhibit anticancer activity in vitro or in animal models and of these, six have been investigated in human cancers. All are non-toxic and very well tolerated. Lentinan and schizophyllan have little oral activity. Active Hexose Correlated Compound (AHCC) is poorly defined but has shown early clinical promise. Maitake DFraction has limited proof of clinical efficacy to date, but controlled research is underway. Two proteoglycans from Coriolus versicolor ‐ PSK (Polysaccharide-K) and PSP (Polysaccharide-Peptide) ‐ have demonstrated the most promise. In Japanese trials since 1970, PSK significantly extended survival at five years or beyond in cancers of the stomach, colon-rectum, esophagus, nasopharynx, and lung (non-small cell types), and in a HLA B40-positive breast cancer subset. PSP was subjected to Phase II and Phase III trials in China. In double-blind trials, PSP significantly extended five-year survival in esophageal cancer. PSP significantly improved quality of life, provided substantial pain relief, and enhanced immune status in 70-97 percent of patients with cancers of the stomach, esophagus, lung, ovary, and cervix. PSK and PSP boosted immune cell production, ameliorated chemotherapy symptoms, and enhanced tumor infiltration by dendritic and cytotoxic T-cells. Their extremely high tolerability, proven benefits to survival and quality of life, and compatibility with chemotherapy and radiation therapy makes them well suited for cancer management regimens.

Antioxidants and cancer, part 3: quercetin.

Abstract: Quercetin is a flavonoid molecule ubiquitous in nature. A number of its actions make it a potential anti-cancer agent, including cell cycle regulation, interaction with type II estrogen binding sites, and tyrosine kinase inhibition. Quercetin appears to be associated with little toxicity when administered orally or intravenously. Much in vitro and some preliminary animal and human data indicate quercetin inhibits tumor growth. More research is needed to elucidate the absorption of oral doses and the magnitude of the anti-cancer effect.

Oligomeric proanthocyanidin complexes: history, structure, and phytopharmaceutical applications.

Abstract: Considerable recent research has explored therapeutic applications of oligomeric proanthocyanidin complexes (OPCs), naturally occurring plant metabolites widely available in fruits, vegetables, nuts, seeds, flowers, and bark. OPCs are primarily known for their antioxidant activity. However, these compounds have also been reported to demonstrate antibacterial, antiviral, anticarcinogenic, anti-inflammatory, anti-allergic, and vasodilatory actions. In addition, they have been found to inhibit lipid peroxidation, platelet aggregation, capillary permeability and fragility, and to affect enzyme systems including phospholipase A2, cyclooxygenase, and lipoxygenase. Based on these reported findings, OPCs may be a useful component in the treatment of a number of conditions. (Altern Med Rev 2000;5(2):144-151)

Male infertility: nutritional and environmental considerations.

Abstract: Studies confirm that male sperm counts are declining, and environmental factors, such as pesticides, exogenous estrogens, and heavy metals may negatively impact spermatogenesis. A number of nutritional therapies have been shown to improve sperm counts and sperm motility, including carnitine, arginine, zinc, selenium, and vitamin B-12. Numerous antioxidants have also proven beneficial in treating male infertility, such as vitamin C, vitamin E, glutathione, and coenzyme Q10. Acupuncture, as well as specific botanical medicines, have been documented in several studies as having a positive effect on sperm parameters. A multi-faceted therapeutic approach to improving male fertility involves identifying harmful environmental and occupational risk factors, while correcting underlying nutritional imbalances to encourage optimal sperm production and function.

Peripheral metabolism of thyroid hormones: a review.

Abstract: Peripheral metabolism of thyroid hormones is a critical component of the impact these hormones have on intracellular function. Thyroid hormones can be metabolized in peripheral tissue by deiodination, conjugation, deamination, and decarboxylation enzyme reactions. Therefore, alterations in these metabolic pathways might significantly impact the quantity of specific thyroid hormone metabolites influencing function at the cellular level. Available evidence also suggests that, under some circumstances, the activity of hepatic antioxidant enzyme systems and lipid peroxidation might influence the peripheral metabolism of thyroid hormones. Several syndromes, such as "euthyroid sick syndrome" and "low T3 syndrome," have been classified within the medical literature. The common feature of these disorders is a low level of circulating T3, with generally normal to slightly elevated blood T4 levels and either normal or slightly suppressed TSH levels. This pattern of altered thyroid hormone levels is generally agreed to be a result of impairment in extra-thyroidal peripheral metabolism. Hepatic and renal pathology, as well as catabolic states such as those induced subsequent to severe injury, illness, or trauma result in consistent shifts in the thyroid hormone profile, secondary to their impact on peripheral enzyme pathways. Lifestyle factors, such as stress, caloric restriction, and exercise, influence peripheral metabolism of thyroid hormones. Exposure to toxic metals, chemical poisons, and several drugs can also influence the peripheral fate of thyroid hormones. While the role of vitamins, minerals, and botanical extracts in thyroid hormone metabolism requires further elucidation, current evidence supports a role for selenium in the hepatic 5'-deiodination enzyme.

Effects of black current anthocyanoside intake on dark adaptation and VDT work-induced transient refractive alteration in healthy humans.

Abstract: The effects of oral intake of a black currant anthocyanoside (BCA) concentrate on dark adaptation, video display terminal (VDT) work-induced transient refractive alteration, and subjective asthenopia symptoms (visual fatigue) were examined in a double-blind, placebo-controlled, crossover study with healthy human subjects. In a dark adaptation study, intake of BCA at three dose levels (12.5-, 20-, and 50 mg/subject, n = 12) appeared to bring about dose-dependent lowering of the dark adaptation threshold. Statistical analysis comparing the values before and after intake indicated there was a significant difference at the 50 mg dose (p= 0.011). Comparing the refraction values for the dominant eye, BCA intake (50 mg/subject, n = 21) resulted in no decrease in the average value after the visual task; whereas, a placebo trial resulted in a large decrease in the average value, resulting in borderline significance (p = 0.064). In the assessment of subjective asthenopia symptoms by questionnaire, significant improvement was recognized on the basis of the statements regarding the eye and lower back after BCA intake.

Parkinson's disease as multifactorial oxidative neurodegeneration: implications for integrative management.

Abstract: Parkinson's disease (PD) is the most common movement pathology, severely afflicting dopaminergic neurons within the substantia nigra (SN) along with non-dopaminergic, extra-nigral projection bundles that control circuits for sensory, associative, premotor, and motor pathways. Clinical, experimental, microanatomic, and biochemical evidence suggests PD involves multifactorial, oxidative neurodegeneration, and that levodopa therapy adds to the oxidative burden. The SN is uniquely vulnerable to oxidative damage, having high content of oxidizable dopamine, neuromelanin, polyunsaturated fatty acids, and iron, and relatively low antioxidant complement with high metabolic rate. Oxidative phosphorylation abnormalities impair energetics in the SN mitochondria, also intensifying oxygen free radical generation. These pro-oxidative factors combine within the SN dopaminergic neurons to create extreme vulnerability to oxidative challenge. Epidemiologic studies and long-term tracking of victims of MPTP (1-methyl-4-phenyl-1,2,3,6,-tetrahydropyridine) poisoning, suggest oxidative stress compounded by exogenous toxins may trigger the neurodegenerative progression of PD. Rational, integrative management of PD requires: (1) dietary revision, especially to lower calories; (2) rebalancing of essential fatty acid intake away from pro-inflammatory and toward anti-inflammatory prostaglandins; (3) aggressive repletion of glutathione and other nutrient antioxidants and cofactors; (4) energy nutrients acetyl L-carnitine, coenzyme Q10, NADH, and the membrane phospholipid phosphatidylserine (PS), (5) chelation as necessary for heavy metals; and (6) liver P450 detoxification support.

Effects of daily oral administration of quercetin chalcone and modified citrus pectin on implanted colon-25 tumor growth in Balb-c mice.

Abstract: The health benefits of fruits and vegetables have been the subject of numerous investigations over many years. Two natural substances, quercetin (a flavonoid) and citrus pectin (a polysaccharide found in the cell wall of plants) are of particular interest to cancer researchers. Two modified versions of these substances ‐ quercetin chalcone (QC) and a pH-modified citrus pectin (MCP) ‐ are the focus of this study. Previous research has confirmed that quercetin exhibits antitumor properties, likely due to immune stimulation, free radical scavenging, alteration of the mitotic cycle in tumor cells, gene expression modification, anti-angiogenesis activity, or apoptosis induction, or a combination of these effects. MCP has inhibited metastases in animal studies of prostate cancer and melanoma. To date, no study has demonstrated a reduction in solid tumor growth with MCP, and there is no research into the antitumor effect of QC. This study examines the effects of MCP and QC on the size and weight of colon-25 tumors implanted in balb-c mice. Fifty mice were orally administered either 1 mL distilled water (controls), low-dose QC (0.8 mg/mL), high-dose QC (1.6 mg/mL), low-dose MCP (0.8 mg/mL) or high-dose MCP (1.6 mg/mL) on a daily basis, beginning the first day of tumor palpation (usually eight days post-implantation). A significant reduction in tumor size was noted at day 20 in all groups compared to controls. The groups given low-dose QC and MCP had a 29-percent (NS) and 38-percent (p<0.02) decrease in size, respectively. The high-dose groups had an even more impressive reduction in size; 65 percent in the QC group and 70 percent in the mice given MCP (both p<0.001). This is the first evidence that MCP can reduce the growth of solid primary tumors, and the first research showing QC has antitumor activity. Additional research on these substances and their effect on human cancers is warranted. Altern Med Rev 2000;5(6):546-552.

Insulin resistance: lifestyle and nutritional interventions.

Abstract: Insulin resistance appears to be a common feature and a possible contributing factor to several frequent health problems, including type 2 diabetes mellitus, polycystic ovary disease, dyslipidemia, hypertension, cardiovascular disease, sleep apnea, certain hormone-sensitive cancers, and obesity. Modifiable factors thought to contribute to insulin resistance include diet, exercise, smoking, and stress. Lifestyle intervention to address these factors appears to be a critical component of any therapeutic approach. The role of nutritional and botanical substances in the management of insulin resistance requires further elaboration; however, available information suggests some substances are capable of positively influencing insulin resistance. Minerals such as magnesium, calcium, potassium, zinc, chromium, and vanadium appear to have associations with insulin resistance or its management. Amino acids, including L-carnitine, taurine, and L-arginine, might also play a role in the reversal of insulin resistance. Other nutrients, including glutathione, coenzyme Q10, and lipoic acid, also appear to have therapeutic potential. Research on herbal medicines for the treatment of insulin resistance is limited; however, silymarin produced positive results in diabetic patients with alcoholic cirrhosis, and Inula racemosa potentiated insulin sensitivity in an animal model.

Attention deficit/hyperactivity disorder (ADHD) in children: rationale for its integrative management.

Abstract: Attention Deficit/Hyperactivity Disorder (ADHD) is the most common behavioral disorder in children. ADHD is characterized by attention deficit, impulsivity, and sometimes overactivity ("hyperactivity"). The diagnosis is empirical, with no objective confirmation available to date from laboratory measures. ADHD begins in childhood and often persists into adulthood. The exact etiology is unknown; genetics plays a role, but major etiologic contributors also include adverse responses to food additives, intolerances to foods, sensitivities to environmental chemicals, molds, and fungi, and exposures to neurodevelopmental toxins such as heavy metals and organohalide pollutants. Thyroid hypofunction may be a common denominator linking toxic insults with ADHD symptomatologies. Abnormalities in the frontostriatal brain circuitry and possible hypofunctioning of dopaminergic pathways are apparent in ADHD, and are consistent with the benefits obtained in some instances by the use of methylphenidate (Ritalin ® ) and other potent psychostimulants. Mounting controversy over the widespread use of methylphenidate and possible life-threatening effects from its long-term use make it imperative that alternative modalities be implemented for ADHD management. Nutrient deficiencies are common in ADHD; supplementation with minerals, the B vitamins (added in singly), omega-3 and omega-6 essential fatty acids, flavonoids, and the essential phospholipid phosphatidylserine (PS) can ameliorate ADHD symptoms. When individually managed with supplementation, dietary modification, detoxification, correction of intestinal dysbiosis, and other features of a wholistic/integrative program of management, the ADHD subject can lead a normal and productive life.

Nutritional strategies for treating chronic fatigue syndrome.

Abstract: Despite considerable worldwide efforts, no single etiology has been identified to explain the development of chronic fatigue syndrome (CFS). It is likely that multiple factors promote its development, sometimes with the same factors both causing and being caused by the syndrome. A detailed review of the literature suggests a number of marginal nutritional deficiencies may have etiologic relevance. These include deficiencies of various B vitamins, vitamin C, magnesium, sodium, zinc, L-tryptophan, L-carnitine, coenzyme Q10, and essential fatty acids. Any of these nutrients could be marginally deficient in CFS patients, a finding that appears to be primarily due to the illness process rather than to inadequate diets. It is likely that marginal deficiencies not only contribute to the clinical manifestations of the syndrome, but also are detrimental to the healing processes. Therefore, when feasible, objective testing should identify them and their resolution should be assured by repeat testing following initiation of treatment. Moreover, because of the rarity of serious adverse reactions, the difficulty in ruling out marginal deficiencies, and because some of the therapeutic benefits of nutritional supplements appear to be due to pharmacologic effects, it seems rational to consider supplementing CFS patients with the nutrients discussed above, along with a general high-potency vitamin/mineral supplement, at least for a trial period.

Natural treatment of perennial allergic rhinitis.

Abstract: Perennial allergic rhinitis is an IgE-mediated inflammatory disorder of the nasal mucosa characterized by paroxysms of sneezing, nasal congestion, pruritis, and rhinorrhea. The condition may be caused by certain environmental agents, food sensitivities, structural abnormalities, metabolic conditions, or synthetic drugs. Recent health impairment outcome studies on allergic rhinitis sufferers reveal a measurable decline in physical and mental health status and the inability to perform daily activities. Antihistamines, decongestants, anticholinergic agents, and corticosteroid drug therapy, alone or in combination, are typically used in the treatment of allergic rhinitis. Reported adverse side effects include sedation, impaired learning/memory, and cardiac arrhythmias. Therapeutic strategies should seek to decrease the morbidity already associated with this condition. Urtica dioica, bromelain, quercetin, N-acetylcysteine, and vitamin C are safe, natural therapies that may be used as primary therapy or in conjunction with conventional methods.

Treatment of Insomnia: An Alternative Approach

Abstract: Insomnia is the most common sleep disorder, and is often associated with significant medical, psychological, and social disturbances. Conventional medical treatment for insomnia includes psychological and pharmacological approaches; however, long-term use of frequently prescribed medications can lead to habituation and problematic withdrawal symptoms. Therefore, herbal and other natural sleep aids are gaining popularity, as herbs commonly used for their sedative-hypnotic effects do not have the drawbacks of conventional drugs. Whether alternative therapies possess activity similar to conventional therapies needs further evaluation. (Altern Med Rev 2000;5(3):249-259)

Use of neurotransmitter precursors for treatment of depression

Abstract: Insufficient activity of the neurotransmitters serotonin and norepinephrine is a central element of the model of depression most widely held by neurobiologists today. In the late 1970s and 1980s, numerous studies were performed in which depressed patients were treated with the serotonin precursors L-tryptophan and 5-hydroxytryptophan (5HTP), and the dopamine and norepinephrine precursors tyrosine and L-phenylalanine. This article briefly reviews the published research on the efficacy of neurotransmitter precursors in treating depression, highlights the findings of studies, and discusses issues regarding the interpretation of those findings. The nature of the studies makes it difficult to draw firm conclusions regarding the efficacy of neurotransmitter precursors for treating depression. While there is evidence that precursor loading may be of therapeutic value, particularly for the serotonin precursors 5-HTP and tryptophan, more studies of suitable design and size might lead to more conclusive results. However, the evidence suggests neurotransmitter precursors can be helpful in patients with mild or moderate depression. (Altern Med Rev 2000;5(1):64-71.)

Beta-carotene: the controversy continues.

Abstract: The three beta-carotene intervention trials: the Beta Carotene and Retinol Efficacy Trial (CARET), Alpha-Tocopherol, Beta-Carotene Cancer Prevention Study (ATBC), and Physician's Health Study (PHS) have all pointed to a lack of effect of synthetic beta-carotene in decreasing cardiovascular disease or cancer risk in well-nourished populations. The potential contribution of beta-carotene supplementation to increased risk of lung cancer in smokers has been raised as a significant concern. The safety of synthetic beta-carotene supplements and the role of isomeric forms of beta-carotene (synthetic all-trans versus "natural" cis-trans isomeric mixtures), in addition to the importance of the protective role of other carotenoids like lycopene and lutein, have become topics of debate in the scientific and medical communities. This review addresses the biochemistry and physiology of the cis versus trans isomers of beta-carotene as well as relevant studies comparing the absorption and storage of the synthetic versus natural forms of beta-carotene. In addition, the risk of potential pro-oxidant effects of synthetic beta-carotene supplementation in intervention trials is evaluated.

The effect of bilberry nutritional supplementation on night visual acuity and contrast sensitivity.

Abstract: PURPOSE: The purpose of this study was to investigate the effect of bilberry on night visual acuity (VA) and night contrast sensitivity (CS). METHODS: This study utilized a double-blind, placebo-controlled, crossover design. The subjects were young males with good vision; eight received placebo and seven received active capsules for three weeks. Active capsules contained 160 mg of bilberry extract (25-percent anthocyanosides), and the placebo capsules contained only inactive ingredients. Subjects ingested one active or placebo capsule three times daily for 21 days. After the three-week treatment period, a one-month washout period was employed to allow any effect of bilberry on night vision to dissipate. In the second three-week treatment period, the eight subjects who first received placebo were given active capsules, and the seven who first received active capsules were given placebo. Night VA and night CS was tested throughout the three-month experiment. RESULTS: There was no difference in night VA during any of the measurement periods when examining the average night VA or the last night VA measurement during active and placebo treatments. In addition, there was no difference in night CS during any of the measurement periods when examining the average night CS or the last night CS measurement during active and placebo treatments. CONCLUSION: The current study failed to find an effect of bilberry on night VA or night CS for a high dose of bilberry taken for a significant duration. Hence, the current study casts doubt on the proposition that bilberry supplementation, in the forms currently available and in the doses recommended, is an effective treatment for the improvement of night vision in this population.

Nutrients and HIV: part three - N-acetylcysteine, alpha-lipoic acid, L-glutamine, and L-carnitine.

Abstract: The role of antioxidants in preventing apoptosis and viral activation in HIV is well documented. N-acetylcysteine, glutathione, and alpha-lipoic acid have been shown to interrupt the process of viral activation and CD4 cell death. L-glutamine has been shown to improve glutathione levels and significantly increase lean body mass in HIV infection. The literature on the use of L-carnitine and acetyl-L-carnitine in treating mitochondrial toxicity, both in muscle and nerve pathologies is relevant in nutritional treatment of HIV, given the mitochondrial toxicity of nucleoside analog reverse transcriptase inhibitor therapy. The current use of highly active antiviral therapies, their toxicity, and significant failure rates have created the need for a more conservative reassessment of HIV treatment. The adjunctive use of nutrient therapy in the treatment of HIV is reviewed here.

Antioxidants and cancer therapy II: quick reference guide.

Abstract: The previous lengthy review concerning the effects of antioxidant compounds used concurrently with radiotherapy and chemotherapy has been reduced to a reference guide There are only three presently known examples in which any agent classifiable as an antioxidant has been shown to decrease effectiveness of radiation or chemotherapy in vivo The vast majority of both in vivo and in vitro studies have shown enhanced effectiveness of standard cancer therapies or a neutral effect on drug action (Altern Med Rev 2000;5(2):152-163)

Environmental medicine, part three: long-term effects of chronic low-dose mercury exposure.

Abstract: Mercury is ubiquitous in the environment, and in our mouths in the form of “silver” amalgams. Once introduced to the body through food or vapor, mercury is rapidly absorbed and accumulates in several tissues, leading to increased oxidative damage, mitochondrial dysfunction, and cell death. Mercury primarily affects neurological tissue, resulting in numerous neurological symptoms, and also affects the kidneys and the immune system. It causes increased production of free radicals and decreases the availability of antioxidants. It also has devastating effects on the glutathione content of the body, giving rise to the possibility of increased retention of other environmental toxins. Fortunately, effective tests are available to help distinguish those individuals who are excessively burdened with mercury, and to monitor them during treatment. Therapies for assisting the reduction of a mercury load include the use of 2,3dimercaptosuccinic acid (DMSA) and 2,3-dimercapto-1-propanesulfonic acid (DMPS). Additional supplementation to assist in the removal of mercury and to reduce its adverse effects is discussed. (Altern Med Rev 2000;5(3):209-223) Methylmercury Sources Mercury is ubiquitous in the environment due to constant off-gassing of mercury from the earth’s crust. This mercury enters waterways, where it is methylated by algae and bacteria. Methylmercury makes its way through the food chain into fish and shellfish, and ultimately into humans. Additional mercury, released from industrial sources into the atmosphere, also is converted in waterways into methylmercury. Because of mercury contamination, 40 states now have warnings on some of their waterways. Warnings of unacceptably high mercury levels in fish have been issued for nearly 15 percent of the nation’s lake acres and five percent of its river and stream miles. In the Pacific Northwest, the most recent finding of high mercury levels is in the sediment of the Spokane River in Washington State. The mercury contamination came from its headwaters ‐ Lake Coeur d’Alene, in northern Idaho. The contamination of this lake with mercury, as well as zinc, lead, cadmium, arsenic, and antimony is believed to have come from more than a century of mining operations in northern Idaho’s Silver Valley. The United States Geological Survey has estimated the bed of Lake Coeur d’Alene contains about 70 million metric tons of contaminated sediment. In 1999, the U.S. Environmental Protection Agency (EPA) directed utilities to measure the amount of mercury released by coal-burning power plants. Mercury is also released into the

Nutrients and HIV: part two--vitamins A and E, zinc, B-vitamins, and magnesium.

Abstract: There is compelling evidence that micronutrient deficiencies can profoundly affect immunity; micronutrient deficiencies are widely seen in HIV, even in asymptomatic patients. Direct relationships have been found between deficiencies of specific nutrients, such as vitamins A and B12, and a decline in CD4 counts. Deficiencies appear to influence vertical transmission (vitamin A) and may affect progression to AIDS (vitamin A, B12, zinc). Correction of deficiencies has been shown to affect symptoms and disease manifestation (AIDS dementia complex and B12; diarrhea, weight loss, and zinc), and certain micronutrients have demonstrated a direct anti-viral effect in vitro (vitamin E and zinc). The previous article in this series focused on selenium and beta carotene deficiencies in HIV/AIDS. This literature review elucidates how deficiencies of the micronutrients zinc, magnesium, vitamins A, E, and specific B vitamins relate to HIV symptomology and progression, and clearly illustrates the need for nutritional supplementation in HIV disease.

Environmental medicine, part one: the human burden of environmental toxins and their common health effects.

Abstract: Chemical compounds ubiquitous in our food, air, and water are now found in every person. The bioaccumulation of these compounds in some individuals can lead to a variety of metabolic and systemic dysfunctions, and in some cases outright disease states. The systems most affected by these xenobiotic compounds include the immune, neurological, and endocrine systems. Toxicity in these systems can lead to immune dysfunction, autoimmunity, asthma, allergies, cancers, cognitive deficit, mood changes, neurological illnesses, changes in libido, reproductive dysfunction, and glucose dysregulation. Chemicals and their effects on these systems are reviewed in this article. Subsequent articles in this series will focus on therapeutic regimens to combat the toxic effects of these and other compounds.

Environmental medicine, part 4: pesticides - biologically persistent and ubiquitous toxins.

Abstract: Although the use of pesticides has doubled every ten years since 1945, pest damage to crops is more prevalent now than it was then. Many pests are now pesticide resistant due to the ubiquitous presence of pesticides in our environment. Chlorinated pesticide residues are present in the air, soil, and water, with a concomitant presence in humans. Organophosphate and carbamate pesticides - the compounds comprising the bulk of current pesticide use - are carried around the globe on air currents. Municipalities, schools, churches, business offices, apartment buildings, grocery stores, and homeowners use pesticides on a regular basis. Pesticides are neurotoxins that can cause acute symptoms as well as chronic effects from repeated low-dose exposure. These compounds can also adversely affect the immune system, causing cell-mediated immune deficiency, allergy, and autoimmune states. Certain cancers are also associated with pesticide exposure. Multiple endocrine effects, which can alter reproduction and stress-handling capacity, can also be found. Limited testing is available to assess the toxic overload of these compounds, including serum pesticide levels and immune system parameters. Treatment for acute or chronic effects of these toxins includes avoidance, supplementation, and possibly cleansing.

The use of nebulized glutathione in the treatment of emphysema: a case report.

Abstract: We present the case of a 95-year-old man with an acute respiratory crisis secondary to emphysema and apparent bronchial infection. Treatment with nebulized glutathione led to a rapid resolution of the crisis, as well as a marked improvement in the chronic course of the disease. This treatment has been used since for a number of patients with emphysema. The safety and bioavailability of this method of delivery have been established in human studies. Preliminary results suggest efficacy for nebulized administration of glutathione in this patient population. We suggest this treatment can be considered an option for acute respiratory crises due to COPD. (Altern Med Rev 2000;5(5):429-431)

The use of ascorbigen in the treatment of fibromyalgia patients: a preliminary trial.

Abstract: Twelve female fibromyalgia syndrome (FMS) patients were given 500 mg per day of a blend containing 100 mg ascorbigen and 400 mg broccoli powder in a preliminary, onemonth, open-label trial. This group of patients showed a mean 20.1 percent (p=0.044) decrease in their physical impairment score and a mean 17.8 percent (p=0.016) decrease in their total fibromyalgia impact scores as measured by the Fibromyalgia Impact Questionnaire. The mean physical impairment score two weeks post-treatment showed a significant return to near pre-treatment level (p=0.028). Analysis of ten of the patients’ mean threshold pain levels at the 18 possible tender points obtained before and at the end of treatment showed a strong trend toward an increase in the mean threshold pain level (p=0.059). The reduced sensitivity to pain and improvement in quality of life measured in this study appear to be clinically relevant and a larger, doubleblind study is warranted. (Altern Med Rev 2000;5(5):455-462)

Hepatitis C; a retrospective study, literature review, and naturopathic protocol.

Abstract: The authors performed a retrospective review of 41 consecutive hepatitis C patients. Of the 14 patients with baseline and follow-up data who had not undergone interferon therapy, seven had a greater than 25-percent reduction in serum alanine aminotransferase (ALT) levels after at least one month on the protocol. For all patients reviewed, the average reduction in ALT was 35 U/L (p=0.026). These data appear to suggest that a conservative approach using diet and lifestyle modification, along with safe and indicated interventions, can be effective in the treatment of hepatitis C. Controlled trials with serial liver biopsy and viral load data are necessary to confirm these preliminary findings. The standard medical treatment of hepatitis C infection is only associated with sustained efficacy in a minority of patients. Therefore, the search for other treatments is of utmost importance. Several natural products and their derivatives have demonstrated benefit in the treatment of hepatitis C and other chronic liver conditions. Other herbal and nutritional supplements have mechanisms of action that make them likely to be of benefit. This article presents comprehensive protocol, including diet, lifestyle, and therapeutic interventions. (Altern Med Rev 2000;5(4):355-370)

Transdermal histamine in multiple sclerosis, part two: a proposed theoretical basis for its use.

Abstract: This paper is the companion to an earlier publication, which discussed preliminary results of transdermal histamine use for ameliorating symptoms of both relapsing-remitting and progressive multiple sclerosis (MS). Here we include preliminary findings on the impairments of digestion and assimilation in MS patients seen in a private clinic. Although only a small number of patients was surveyed, an association was found between impaired gastric acid production, impaired protein hydrolysis, and subnormal plasma histidine levels in patients with MS. Impaired digestion might, therefore, impair the ability of MS patients to synthesize histamine. This paper discusses how impairment of histamine synthesis might lead to symptoms of MS, and conversely how exogenously administered histamine might alleviate symptoms. Various mechanisms of action are suggested, including: enhanced gastric acid and pancreatic enzyme secretion, augmentation of subnormal cerebral tissue levels of histamine, improved electrical function of demyelinated fibers, increased cerebral blood flow, suppression of aberrant autoimmune responses, and stimulation of remyelination. We also discuss the observed failure of digestive function in MS and point out that pathological changes which parallel CNS findings have been found in the enteric nervous system (ENS) of patients with Parkinson's disease. Similar parallels might exist between the CNS and ENS in multiple sclerosis.

Environmental medicine, part 2 - health effects of and protection from ubiquitous airborne solvent exposure.

Abstract: Chemicals known as solvents are part of a broad class of chemicals called volatile organic compounds. These compounds are used in a variety of settings, are ubiquitous, and off-gas readily into the atmosphere. Asa result of their overuse, they can be found in detectable level virtually all samples of both indoor and outdoor air. Certain of these compounds are detectable in adipose samples of all U.S. residents Once in the body they can lead to a variety of neurological, immunological, endocrinological, genitourinary, and hematopoietic problems. Some individuals also have metabolic defects that diminish the liver's clearing capacity for these compounds. Supplementation may be of benefit to help clear these compounds from the body and to prevent adverse health effects.

Peripheral intravenous nutrition therapy: outpatient, office-based administration.

Abstract: BACKGROUND: The use of peripheral intravenous nutrition (PIN) has been growing in recent years due to the increase in awareness of the pathophysiological mechanisms of peripheral vein thrombophlebitis, as well as the availability of techniques to prevent or retard its onset. With the increase in public and medical practitioner awareness of the importance of nutritional interventions in health and disease, more outpatient-based PIN therapy is being performed. Outpatient, office-based PIN has unique features including high osmolality, high infusion rates, and short infusion duration. METHODS: Previous intravenous nutrition studies were used to estimate safety parameters for outpatient, office-based PIN. CONCLUSIONS: Osmolalities of the infusion can approach 1000 mOsm/L if the duration of the infusion is only several hours. The infusion should be diluted to reduce the osmolality, even if an increase in infusion rate is necessary. Duration of infusion should be less than three hours to reduce the time the irritating mixture contacts the vein wall. This requires high (150 ‐ 330 mL/hour) infusion rates. The largest vein, and smallest and shortest catheter possible to achieve the infusion rate desired should be used, with in-line filtration of at least 0.45mm. The cannula should be removed at the first sign of pain or redness. Standard procedures to reduce infection risks should be followed. (Altern Med Rev 2000;5(4):347-354)
