Adhatoda vasica Nees belonging to family Acanthaceae, commonly known as Adosa, is found many regions of India and throughout the world, with a multitude of uses in traditional Unani and Ayurvedic systems of medicine. It is also called Vasaka. It is a well-known herb in indigenous systems of medicine for its beneficial effects, particularly in bronchitis. Vasaka leaves, bark, the root bark, the fruit and flowers are useful in the removal of intestinal parasites. Vasaka herb is used for treating cold, cough, chronic bronchitis and asthma. In acute stages of bronchitis, vasaka gives unfailing relief, especially where the sputum is thick and sticky. It liquefies the sputum so that it is brought up more easily. For relief in asthma, the dried leaves should be smoked. The juice from its leaves should be given in doses of 2 to 4 grams in treating diarrhea and dysentery. A poultice of its leaves can be applied with beneficial results over fresh wounds, rheumatic joints and inflammatory swellings. A warm decoction of its leaves is useful in treating scabies and other skin diseases. In olden times its leaves were made into a decoction with pepper and dried ginger. But the modern medicine searched its active ingredients and found out that vasicine, oxyvascicine and vasicinone are the alkaloids present in vasaka and in which vasicine is the active ingradient for expelling sputum from the body.Asian J.

Screening of plant extracts from wild species of plants for insecticidal properties could lead to the discovery of new agents for pest control. Keeping this in view, the insecticidal activity of three plant extracts Helencha (Enhydra fluctuans Lour), Ghetu (Clero dendrum viscosum Vent) and Kalomegh (Andrographis peniculata Wall) were tested against stored grain pest Tribolium castaneum (Herbst). In residual film bioassay, five doses, i. e. 0.629, 0.472, 0.315, 0.157 and 0.078 mg/cm 2 of methanol extract of leaves of each plant species were applied on adult Tribolium castaneum. After 36 hours, the lowest LD 50 for the methanol extract of leaves of Enhydra fluctuans, Clerodendrum viscosum and Andrographis peniculata were found to be 0.351, 0.622 and 0.977 mg/cm 2 , respectively. According to the intensity of activity, the toxicity was found in the order of Enhydra fluctuans > Clerodendrum visco sum > Andrographis peniculata. The overall results suggest that these three plants have potential insecticidal effect which might be used in pest control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
