Strychnos nux-vomica L., the most extensively studied Strychnos species because of its former importance in pharmacy, is a moderate-sized tree from the family Loganiaceae, with a short, pretty thick, often crooked trunk, distributed in an area stretching from India and Sri Lanka to Indo-China. Almost all parts of S. nux-vomica seem to have been used for one medical purpose or another [1,2]. The dried ripe seeds called nux vomica as a traditional folk medicine are employed widely in China for the treatments of rheumatoid arthritis, swelling pain, trauma, bone fracture, facial nerve paralysis, myasthenia gravis, and poliomyelitis sequela.
