Simmondsin is an extract of jojoba seeds (pronounced "ho-HO-bah") (Simmondsia chinensis), it was traditionally thought to be a toxic substance due to jojoba seed meal causing weight loss in animals, but recently it has been researched as a potential treatment for reducing appetite of obese individuals by helping to reduce craving for food.[1] Several mechanisms of action are thought to be involved in the appetite suppressant effect.[2][3][4][5]
