Plants have been used for medical purposes since the beginning of human history and are the basis of modern medicine. Most chemotherapeutic drugs for cancer treatment are molecules identified and isolated from plants or their synthetic derivatives. Our hypothesis was that whole plant extracts selected according to ethnobotanical sources of historical use might contain multiple molecules with an...

The effect of methanolic plant extracts from Solanum nigrum, Acokanthera spectabilis and Heliotropium aegyptiacum were investigated on the larval mortality and development of Culex pipiens L. Also, the effects of the LC50 of the three plant extracts on the larval haemogram were studied. Plant extracts exhibited variable bioactivities. The greatest activity was observed for S. nigrum which showe...

Ethanolic extracts of 45 Indian medicinal plants traditionally used in medicine were studied for their antimicrobial activity against certain drug-resistant bacteria and a yeast Candida albicans of clinical origin. Of these, 40 plant extracts showed varied levels of antimicrobial activity against one or more test bacteria. Anticandidal activity was detected in 24 plant extracts. Overall, broad-...
