TL;DR: The use of medicinal plants in the treatment and prevention of diseases is attracting the attention of scientists worldwide as mentioned in this paper, and approximately 3000 plant species are currently used by an estimated 200,000 indigenous traditional healers in South Africa for medicinal purposes.

TL;DR: Brine shrimp lethality assay found eleven out of the 118 extracts showed significant toxicity to the brine shrimp, which could be useful in the search for new antitumor compounds from the Indian flora.
Abstract: Medicinal plants constitute important components of flora and are widely distributed in different regions of India. Based on ethnomedical significance, we have collected several medicinal plants used in traditional medicine from Eastern Ghats of India and evaluated for their biological activity. In the present study, a method utilizing brine shrimp (Artemia salina Leach) lethality was used to screen medicinal plants for their biological activity. Aqueous extracts from 118 Indian medicinal plants were screened by the brine shrimp lethality assay and found eleven out of the 118 extracts showed significant toxicity to the brine shrimp (＜60 μg/ml). Polygonum cuspidatum and Syzygium cumini extracts have exhibited potent activity with LC50 13.5 and 20, respectively. The results were analyzed within the context of the available traditional knowledge and uses for these plants. Present study could be useful in the search for new antitumor compounds from the Indian flora.

TL;DR: In this review, various Indian plants which have the potential of immunomodulating activity are identified from various sources in the literature including both plant extracts and synthetic peptides are identified.
Abstract: In this review we have attempted to highlight the work on immunomodulators carried out in Indian laboratories including both plant extracts and synthetic peptides. The results for plant extracts are reviewed in part I of this review and synthetic peptides in part II. Various Indian plants which have the potential of immunomodulating activity are identified from various sources in the literature. Among these"14 have undergone in vitro and in vivo evalution, mostly in animals and to some extent in humans as well. While the leads are extremely promising for some of them such as Asparagus racemosus. Azadirachta indica, Curcuma longa, Ocimum sanctum, Panax ginseng, Picrorhiza kurroa, Tinospora cordifolia, Withania somnifera etc., considerable work remains to be done for the remainder plants.

TL;DR: About 65% of all the plants mentioned in the survey have been documented to have toxic effect on the liver and kidney of experimental mice, showing the need for more research in order to identify lead compounds in indigenous antimalarial plants with less or no toxicity.
Abstract: An ethnobotanical survey of herbal medicine used for treatment of malaria fever in 17 communities in Ogun State, Southwest Nigeria was carried out. According to the results, 38 plant species belonging to 24 families were used in herbal antimalarial recipes. Among the plants mentioned, the most frequently used wereMorinda lucida (7.87%), Lawsonia inermis (7.41%), Citrus medica (6.94%),Sarcocephalus latifolius (6.48%) and Morinda morindiodes (6.48%). Investigations were carried out on the plant part (leaf, stem or root) used, method of preparing herbal antimalarial remedies and how it is administered. Result showed that irrespective of plant and part (leave, fruit, stem bark or root bark) or combinations of the plant parts, water and aqueous extract from fermented maize were the main medium of herbal antimalarial preparations. Treatment regimens of malaria generally included drinking, bathing and steam inhalation of the aqueous herbal preparations for 4 - 10 days or until symptoms of malaria disappear. About 65% of all the plants mentioned in the survey have been documented to have toxic effect on the liver and kidney of experimental mice. Continuous consumption of these plants could therefore have pathological effects on the consumers. Hence, this show the need for more research in order to identify lead compounds in indigenous antimalarial plants with less or no toxicity.
