JKl, I read where Neem Oil is basically Non Toxic to most animals and people, in fact in India it has been used in various forms for its medicinal properties for centuries, from everything like acne to fever. It was proven when fed to laboratory rats for several weeks to cause 100% reversible sterility, and should not be consumed by women who are pregnant, trying to become pregnant, nursing or children, it also has been found to be an abortifactent when consumed by pregnant rats. In India its been used as in Teas, used as a poultice and just eaten for varying purposes. Its made by pressing or boiling and pressure extraction of the seeds and fruits of Neem trees, and therefore varies greatly in the concentration between the various methods of obtaining the oils.
