Pharmacognostic Characterization of Stem and Root of Adhatoda zeylanica Medicus

ABSTRACT Adhatoda zeylanica Medicus is a well-known plant drug in Ayurvedic, Unani-Tibbi, Siddha, Allopathic, Homeopathic, Naturopathic & Home Remedies. The present communication deals with the pharmacognostic evaluation on the stem and root of Adhatoda zeylanica Medicus (Acanthaceae). Macroscopic and microscopic examinations of the different organ, observations, and differential microchemical test has been carried out for the authentication of the samples. Physiochemical values such as the percentage of total ash, acid insoluble ash, acid soluble ash, extractive values like petroleum ether-soluble extractives, alcohol-soluble extractives and water-soluble extractives were calculated as well as histochemical tests and colour reactions with different chemicals were performed.

    ABSTRACT: A total of 105 plants used for food and medicine and 11 animals hunted and gathered for meat by the Khasis and Garos of Meghalaya were identified. Of the total plants recorded, 85 were used by the Garos alone, only three by the Khasis whereas the other 17 were used by both tribes. In addition to fresh use in-season many plant products were processed for storage and use off-season. Although all adults were familiar with various uses of plants and animals, the village elders were more knowledgeable. Garos have especially knowledgeable curers. Wild foods are of particular value for tiding over lean periods when resources from agriculture and animal husbandry systems are scarce, especially for the poorer sections of society. The importance of recording the use of plants and animals in this region is especially important because of rapid loss of rain forest habitats.
