Nux Vomica
Nux vomica is a tree whose seeds are used to make medicine. They contain strychnine and brucine, two toxic chemicals. Nux vomica is also used in homeopathy, a system of alternative medicine that uses very dilute substances to treat erectile dysfunction (ED), stomach swelling, constipation, anxiety, migraine, and many other conditions. However, homeopathy is not supported by scientific evidence, and there is no reason to believe that nux vomica is effective in homeopathic dilutions.
