TL;DR: The present paper reviews the active, natural principles and crude extracts of plants which have been experimentally studied for hypoglycemic activity in the last ten years.

TL;DR: It appears that the two methyl groups of cantharidin are not the main functional groups for antitumor activity and for the stimulation of bone marrow but are associated with urinary irritation.

TL;DR: This review summarises the literature on the antidiabetic activity of 343 medicinal plants reputed in the indigenous system of medicine or in which the pharmacological activity has been scientifically demonstrated.

TL;DR: An ethanolic extract of the rhizomes of Zingiber officinale was investigated for anti-inflammatory, analgesic, antipyretic, antimicrobial and hypoglycaemic activities in rats and rabbits and was ineffective in suppressing the writhing induced by intraperitoneal acetic acid.

TL;DR: The decoction of Cymbopogon citratus leaves showed some dose-related hypotensive effects given intravenously and some weak diuretic and anti-inflammatory effect when given orally.

TL;DR: The extract showed a morphine-like inhibition of acetylcholine release in the coaxially stimulated ileum, together with an initial increase in muscular tone, followed by a gradual decrease, which was found to be due to quercetin.

TL;DR: Five plants (Myrtus communis, Apium graveolens, Matricaria chamomilla, Withania somnifera and Achillea santolina) grown in Iraq were assessed for their anti-inflammatory activity on intact rats by measuring the suppression of carrageenan-induced paw edema produced by 1% of the intraperitoneal LD50 doses for the respective 80% ethanol extracts.

TL;DR: There is considerable scope for new drug discovery from traditional medicines which are used throughout the world and some recent developments are commented upon and conclusions are made.

TL;DR: The main ingredient in turmeric is curcumin which is known to be an anti-oxidant and a possible free radical scavenger which could make it useful as an anticarcinogen.

TL;DR: Preliminary antibacterial screening of local crude drugs was carried out using the cariogenic bacterium, Streptococcus mutans, and Morus australis, Ludwigia octovalvis and Thuja orientalis were very effective in inhibiting the growth of serotypes c and d of S. mutans.

TL;DR: Simultaneous administration of testosterone propionate to F-treated intact adult and castrated prepubertal dogs maintained the viability of spermatozoa, kept epididymal physiology relatively normal and significantly increased the cellular heights of epididysmides.

TL;DR: Three plant drugs were studied against aspirin-induced gastric ulcers in rats and their effects on output of gastric acid and pepsin and hexosamine concentrations in gastric fluid suggested gastric mucosal protection.

TL;DR: Crude hot water extracts from eight medicinal plants collected in Togo, West Africa, were examined for antimalarial properties against Plasmodium falciparum using an in vitro test and the activity differed with the plant species.

TL;DR: Aconitan A did not affect plasma insulin levels in normal, glucose-loaded and alloxan-induced hyperglycemic mice and gave no influence on insulin binding to isolated adipocytes, and did not change the total cholesterol and triglyceride contents of plasma and liver.

TL;DR: All samples were found to be antimicrobially active in the screening of essential oils of four Ocimum species grown in Rwanda.

TL;DR: A series of 20 medicinal plants used in the Rwandese traditional medicine to treat diarrhoeal diseases has been screened for antibacterial activity against several Salmonella and Shigella and for antidiarrhoeal activity on mice.

TL;DR: Sixtynine plants are listed, which are used by traditional healers in five regions of Eastern Tanzania, Coast, Dar es Salaam, Kilimanjaro, Morogoro and Tanga, and results of a literature survey on medicinal uses, isolated constituents, and pharmacological effects are provided.

TL;DR: The petroleum and ethyl acetate extracts of the stem bark from Butea monosperma displayed antifungal activity against Cladosporium cladosporioides, and the active constituent of low polarity was isolated by bioassay-monitored chromatographic fractionation and identified as (-)-medicarpin by comparison of physical data.

TL;DR: The essential oil of Bupleurum gibraltaricum showed considerable anti-inflammatory activity against carrageenan-produced pedal edema in rats, and appeared to be due to the delta-3-carene component.

TL;DR: Effect of an aqueous extract of Spondias mombin leaves on whole animals, and isolated gravid and non-gravid uteri of mice, rats and guinea-pigs is studied.

TL;DR: The data support the traditional belief that T. crispa extract could improve diabetic conditions by virtue of its action on the endocrine pancreas.

TL;DR: Pourtant il est evident that les plantes medicinales forment une grande source potentielle, encore insuffisamment appliquee dans les Soins de the Sante Primaires.

TL;DR: The interdisciplinary methods used in the recording and collecting of ethnopharmacological field data are described, including the collection of botanical and pharmacological specimens and procedures of data collection in field studies of medicinal plants.

TL;DR: The hypoglycemic activity of several seaweed extracts on rabbits was studied and their effects on glycemia and triglyceridemia evaluated.

TL;DR: Les resultats indiquent que l'efficacite de l'extrait est equivalent a celui du metoclopramide.

TL;DR: The history of arrow and dart poisons is briefly reviewed and this is followed by an outline of their use throughout the world and some applications of arrow- and dart-poison constituents as medicinal agents and pharmacological tools are indicated.

TL;DR: Using western biomedical criteria of efficacy, 92% of the medicinal plants being cultivated were found to be potentially efficacious and the frequent use of these plants in diet suggests that they have served to mediate against illness and disease states in the cultural and natural environment in which the practices evolved.

TL;DR: The effect of methanol and acetone extracts of the epigeal parts of Peganum harmala, a common medicinal plant among Bedouins in Israel, was studied on several parameters of reproduction in female rats to produce a dose-dependent significant decrease in litter size.

TL;DR: The traditional phytotherapy of the Sherpas of the Helambu region, Central Nepal, has been investigated, and the vast number of prescriptions available to treat ailments suggest ample opportunities for their critical scientific study.
