Nux vomica is a plant. The seed is used to make medicine.
Despite serious safety concerns, nux vomica is used for diseases of the digestive tract, disorders of the heart and circulatory system, diseases of the eye, and lung disease. It is also used for nerve conditions, depression, migraine headache, symptoms of menopause, and a blood vessel disorder called Raynaud's disease.
Other uses include treatment of “tired blood” (anemia), as a tonic, and as an appetite stimulant.
In manufacturing, nux vomica is used as rat poison. That's because it contains strychnine and brucine, two deadly chemicals.

Nux vomica contains strychnine and other chemicals that affect the brain and cause muscle contractions. This can lead to convulsions and death. Strychnine in amounts that are too small to produce symptoms can still be a serious problem. Small amounts of strychnine build up in the body with continued use, especially in people with liver disease. This can cause death in a period of weeks. Strychnine poisoning can be detected with laboratory tests.
Nux vomica is UNSAFE. Taking nux vomica for more than a week, or in high amounts of 30 mg or more, can cause severe side effects. Some of these side effects include restlessness, anxiety, dizziness, neck and back stiffness, spasms of jaw and neck muscles, convulsions, seizures, breathing problems, liver failure, and death.
Special Precautions & Warnings:No one should take nux vomica, but certain people are especially at risk for toxic side effects. These side effects are especially dangerous if you have any of the following conditions:
Pregnancy and breast-feeding: Taking nux vomica can harm both mother and child. Don't use it.
Liver disease: The strychnine in nux vomica can cause liver damage or make liver disease worse. Don't use it.
The appropriate dose of nux vomica depends on several factors such as the user's age, health, and several other conditions. At this time there is not enough scientific information to determine an appropriate range of doses for nux vomica. Keep in mind that natural products are not always necessarily safe and dosages can be important. Be sure to follow relevant directions on product labels and consult your pharmacist or physician or other healthcare professional before using.
Natural Medicines Comprehensive Database rates effectiveness based on scientific evidence according to the following scale: Effective, Likely Effective, Possibly Effective, Possibly Ineffective, Likely Ineffective, and Insufficient Evidence to Rate (detailed description of each of the ratings).
Report Problems to the Food and Drug Administration
You are encouraged to report negative side effects of prescription drugs to the FDA. Visit the FDA MedWatch website or call 1-800-FDA-1088.
