Neem is a tree. The bark, leaves, and seeds are used to make medicine. Less frequently, the root, flower, and fruit are also used. Salimuzzaman Siddiqui was the first scientist to discover the antibacterial, antiviral, anthelmintic and antifungal, constituents of the Neem tree. In 1942, he extracted three bitter compounds from neem oil, which he named as nimbin, nimbinin, and nimbidin respectively.
