Nux vomica is the dried, ripe seed of Strychnos nux-vomica L., a native tree of Burma, China, eastern India, Thailand, and northern Australia. There are reports of toxic effects with traditional use of the seeds or fruit of Strychnos nux-vomica L.
In homeopathy, nux vomica is used for allergies, back pain, colds, constipation, digestive problems, emotional stress, flu, hangovers, headaches, hemorrhoids, and menstrual problems. Nux vomica is also a polycrest, or a homeopathic remedy used to treat many ailments. As a polycrest, nux vomica's primary indication is for disorders related to abuse of narcotic drugs, alcohol, coffee, or tobacco, overindulgence of rich food and beverages, and mental strain from excessive work.
Athough nux vomica appeared as a treatment in 19th Century medical publications, there is very little documentation on its therapeutic effectiveness in today's standard medical journals. However, because nux vomica is a common homeopathic medicine, research continues on it, albeit in laboratory and animal studies. This remedy is in the category of unapproved herbs according to the German Commission E.
