Neem-based products from Azadirachta indica have been successfully used for pest control in agriculture and gardening since long in India and more recently in European countries and in the USA (1). The seed kernels, particularly rich in bioactive azadirachtin and other limonoids (tetranortriterpenoids), are the main source for a large number of products used for the control of pest insects, mites, fungi and soil-borne nematodic root parasites (1). Surprisingly, registered neem products for the control of pathogens, ectoparasites or disease vectors affecting human and animal health are few. The moderate interest of chemical and pharmaceutical industries for developing neem-based products for human health stands in sharp contrast to the wide traditional use of neem preparations by populations of different cultures, in India, in other Asian countries and in Africa. Leaves, seeds, roots, bark and the flowers of the plant are used to cure different ailments, such as jaundice and stomach ulcers and to combat a variety of infectious and parasitic diseases, ranging from leprosy, to chicken pox, to malaria (2).
