Background

  • 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.

Tradition

    Disclaimer

    The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below.

Dosing

    Disclaimer

    The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

  • Adults (18 years and older):

    • There is no proven safe or effective dose for nux vomica. As pills or powders, 0.3-0.9g per day has traditionally been used.
    • Homeopathic preparations are the most commonly used form, and nux vomica comes in several strengths, including 6X, 12X, 30X, and 30C. Traditionally, sublingual doses are taken one-half hour before or after eating, brushing teeth, or drinking anything but water.
  • Children (younger than 18 years):

    • There is no proven safe or effective dose for nux vomica, and use in children is not recommended due to potential toxicity. In children, as little as 50mg of seed may cause intoxication or death.

Safety

    Disclaimer

    The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

  • Allergies

    • Avoid in individuals with a known allergy or hypersensitivity to Strychnos nux-vomica.
  • Side Effects and Warnings

    • In general, nux vomica has predominantly neurological effects, and may cause painful seizures, spasms, difficulty breathing, dizziness and confusion. Other adverse effects include muscle cramps, pain and tenderness.
    • Chest discomfort, tonic contractions of all limb muscles, carpopedal spasm, muscle pain, numbness, hyperventilation, confusion, hyperreflexia, nystagmus (rapid movement of the eyes), knee-jerks, tiredness and seizure have been reported after taking a multi-herb concoction containing nux vomica. Seizures can occur within 15 minutes of ingestion (or five minutes of inhalation) and may result in hyperthermia, metabolic and respiratory acidosis, rhabdomyolysis, and myoglobinuric renal (kidney) failure. Strychonos nux-vomica fruit may also cause crampy abdominal and leg pain and tense thigh muscles with tenderness to touch.
    • Avoid taking nux vomica seeds by mouth, as the seeds may contain toxic amounts of strychnine. Use cautiously in other forms due to potential toxicity from strychnine in nux vomica. Also use cautiously in patients with seizure disorders, as nux vomica has induced seizures.
  • Pregnancy and Breastfeeding

    • Nux vomica should not be taken during pregnancy or breastfeeding due to risk of ingestion of toxic levels of strychnine. No safe internal dosage or maximum duration of homeopathic nux vomica during pregnancy or breastfeeding has been clinically established.

Interactions

    Disclaimer

    Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.

  • Interactions with Drugs

    • Anti-psychotics and phenothiazines are contraindicated in individuals with symptoms of poisoning, as they may compound the symptoms exhibited by the patient. Use is not recommended with nux vomica.
    • Strychnine in nux vomica can accumulate in the liver with extended administration, and especially in those with liver damage. Patients taking drugs that are potentially damaging to the liver should consult with a qualified healthcare professional, including a pharmacist.
  • Interactions with Herbs and Dietary Supplements

    • Strychnine in nux vomica can accumulate in the liver with extended administration, and especially in those with liver damage. Patients taking herbs and supplements that are potentially damaging to the liver, such as kava, should consult with a qualified healthcare professional, including a pharmacist.
