TL;DR: The wealth of tribal knowledge on medicinal plants points to a great potential for research and the discovery of new drugs to fight diseases including diabetes, obtaining new foods and other new uses.
Abstract: Medicinal plants used to treat diabetic conditions are of considerable interest and a number of plants have shown varying degrees of hypoglycaemic and antihyperglycaemic activity. An ethno-medicobotanical survey was carried out among the Kani and Paliyar tribals in southern Western Ghats of Tamil Nadu for the exploration of antidiabetic herbal medicines. They frequently use ten species of plants for the treatment of diabetes either in single or in combination with some other plant parts. The wealth of tribal knowledge on medicinal plants points to a great potential for research and the discovery of new drugs to fight diseases including diabetes, obtaining new foods and other new uses.

TL;DR: The extract and active compounds of the medicinal plants introduced in this review article could open a way to conduct clinical trials on cancer and greatly help researchers and pharmacists develop new anticancer drugs.
Abstract: Increase in cases of various cancers has encouraged the researchers to discover novel, more effective drugs from plant sources. This study is a review of medicinal plants in Iran with already investigated anticancer effects on various cell lines. Thirty-six medicinal plants alongside their products with anticancer effects as well as the most important plant compounds responsible for the plants' anticancer effect were introduced. Phenolic and alkaloid compounds were demonstrated to have anticancer effects on various cancers in most studies. The plants and their active compounds exerted anticancer effects by removing free radicals and antioxidant effects, cell cycle arrest, induction of apoptosis, and inhibition of angiogenesis. The investigated plants in Iran contain the compounds that are able to contribute effectively to fighting cancer cells. Therefore, the extract and active compounds of the medicinal plants introduced in this review article could open a way to conduct clinical trials on cancer and greatly help researchers and pharmacists develop new anticancer drugs.

TL;DR: The present review summarizes some important pharmacological and preliminary studies on medicinal plants, products thereof and isolated principles from them, which can be investigated further to achieve lead molecules in the search of novel herbal drugs.
Abstract: Modern synthetic medicines are very effective in curing diseases but also cause a number of side effects. Crude drugs are less efficient with respect to cure of diseases but are relatively free from side effects. Parasites have been of concern to the medical field for centuries and the helminths considered causing considerable problems for human beings and animals. A large number of medicinal plants are claimed to possess anthelmintic property in traditional systems of medicine and are also utilized by ethnic groups worldwide. Following the folk claims, several medicinal plants have been scrutinized for this activity using various in vitro and in vivo methods. The present review summarizes some important pharmacological and preliminary studies on medicinal plants, products thereof and isolated principles from them, which can be investigated further to achieve lead molecules in the search of novel herbal drugs.

TL;DR: The medicinal plants and herbs have been used for many years in the treatment of various diseases in animals and human beings and now-a-days, utilization of these medicinal plants is increasing because of prohibition of most of the antimicrobial growth promoters in animal feed.
Abstract: The medicinal plants and herbs have been used for many years in the treatment of various diseases in animals and human beings. Now-a-days, utilization of these medicinal plants is increasing. These are used in animal feed as the growth promoters. Due to prohibition of most of the antimicrobial growth promoters in animal feed because of their residual effects, plant extracts are becoming more popular. They act as antibacterial, antioxidant, anticarcinogenic, antifungal, analgesic, insecticidal, anticoccidial and growth promoters. These plant extracts compete with the synthetic drugs. Majority of medicinal plants do not have the residual effects. Azadiracht indica, Zizyphus vulgaris, Ocimum gratissimum and Atlanta monophylla have the strong antibacterial activity, whereas ocimum plant has strong antioxidant, anticarcinogenic, antifungal, analgesic and antipyretic properties. Leaves of Azadirachta indica are used for feeding and reducing the parasitic load of animals. The fruit of Azadirachta indica also has the anticoccidial activity for poultry.

TL;DR: Potential use of these plants for developing new antibacterial compounds against pathogenic microorganisms is revealed and the presence of phytochemicals such as alkaloids, tannins, triterpenoids, steroids and glycosides in the extracts ofThese plants supports their traditional uses as medicinal plants for the treatment of various ailments.
Abstract: Delonix elata, Enicostemma axillare, Merremia tridentata, Mollugo cerviana and Solanum incanum are medicinal plants used in traditional Indian medicine for the treatment of various ailments. These plants were selected to evaluate their potential antibacterial activity. To determine antibacterial activity and phytochemicals in the crude extracts of five medicinal plants used in traditional Indian medicine for the treatment of various ailments like rheumatism, piles fever, skin diseases and snake bite. The antibacterial activity of organic solvent extracts of these plants were determined by disc diffusion and broth dilution techniques against grampositive bacterial strains (Bacillus subtilis, Staphylococcus aureus) and gram-negative bacterial strains (Escherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa). Results revealed that the chloroform and methanol extracts of D. elata and methanol extracts of M. cerviana exhibited significant antibacterial activity against gram-positive and gram-negative strains with minimum bactericidal concentration (MBC) ranging from 1.5 to 100 mg/ml. Methanol extracts of M. tridentata exhibited activity only against gram-positive bacterial strains with MBC ranging from 12.5 to 100 mg/ml. Extracts of E. axillare and S. incanum showed activity only against B. subtilis and were not bactericidal at 100 mg/ml. The most susceptible organism to the organic extracts from all the studied plants was B. subtilis and the most resistant organism was P. aeruginosa. The presence of phytochemicals such as alkaloids, tannins, triterpenoids, steroids and glycosides in the extracts of these plants supports their traditional uses as medicinal plants for the treatment of various ailments. The present study reveals potential use of these plants for developing new antibacterial compounds against pathogenic microorganisms.
