Strychnos Nux-Vomica (Strychnos nux-vomica)

Botanical Information

  • Family: Loganiaceae
  • Common Names: Nux Vomica, Poison Nut, Quaker Buttons
  • Parts Used: Seeds, Bark

Description

Strychnos nux-vomica is a deciduous tree native to India, Southeast Asia, and Australia. The seeds contain potent alkaloids, particularly strychnine and brucine, making them highly toxic in large doses. Despite this, Nux Vomica has been traditionally used in small, highly diluted preparations in homeopathy and herbal medicine to stimulate digestion, nervous system function, and circulation.

Historical and Traditional Uses

  • Used in Ayurvedic and Unani medicine as a digestive stimulant and nerve tonic (after detoxification).
  • Historically employed in very small doses for lethargy, sluggish digestion, and constipation.
  • Used in homeopathy for digestive complaints, irritability, and nervous system disorders.
  • Applied externally in diluted form for joint pain and rheumatism.

Constituents

  • Alkaloids (strychnine, brucine)
  • Glycosides
  • Fixed oils
  • Lignans

Actions

  • Nervine stimulant
  • Digestive tonic
  • Circulatory stimulant
  • Antispasmodic (in controlled doses)
  • Homeopathic remedy for overindulgence and digestive distress

Medicinal Uses

⚠️ Due to its toxicity, Strychnos nux-vomica should only be used in homeopathic or highly controlled herbal preparations.

1. Digestive Stimulation:
Traditionally used in highly diluted doses to stimulate digestion and relieve bloating and constipation.

2. Nervous System Support:
Considered a nervine stimulant in homeopathy, used for exhaustion and nervous tension.

3. Circulatory Health:
Used historically in very small amounts to stimulate circulation and warm extremities.

4. Pain Relief (Topical Use):
Diluted tinctures have been applied externally for muscle pain, neuralgia, and joint stiffness.

Preparation and Dosage

⚠️ This herb is toxic in even moderate doses and should only be used in homeopathic or professionally prepared herbal remedies.

Homeopathic Preparation:

  • Nux Vomica 6X or 30C is commonly used for digestive discomfort, irritability, and headaches.

Tincture (Highly Diluted):

  • Used externally for rheumatic pain under expert supervision.

Decoction (Traditional Use, Not Recommended for Internal Use):

  • Historically, the seeds were detoxified before use; this method is not advised for general herbal practice today.

Precautions and Contraindications

  • Toxicity Warning: Contains strychnine, which is highly toxic and can cause convulsions, respiratory failure, and death.
  • Pregnancy and Lactation: Absolutely contraindicated.
  • Neurological Disorders: Avoid use in conditions such as epilepsy or nervous system disorders.
  • Not for Self-Medication: Only use under the guidance of a qualified practitioner.

Energetics (Traditional Medicine Perspectives)

  • Ayurveda: Heating and stimulating; sometimes used after detoxification, but generally avoided due to toxicity.
  • Traditional Chinese Medicine (TCM): Rarely used due to toxicity but classified as a warming herb that moves stagnation.
  • Homeopathy: Used in minute doses for digestive, emotional, and nervous system imbalances.

Combinations

  • For Digestive Support: Typically used in homeopathy alongside Lycopodium or Pulsatilla.
  • For Circulatory Health: Combined in very controlled settings with warming herbs like ginger.
  • For Pain Relief (Topical): Combined with arnica or menthol-based rubs.

Harvesting and Storage

  • Harvesting: Seeds are collected from mature fruits and dried carefully.
  • Drying: Air dry in a well-ventilated area away from direct sunlight.
  • Storage: Store dried seeds and extracts in airtight containers away from children and pets.

Modern Research

Studies confirm Strychnos nux-vomica’s stimulant effects on the nervous system, but its toxicity limits its modern use to homeopathy and controlled pharmacological applications.

Nux Vomica remains a highly potent and potentially dangerous herb, primarily used in homeopathy and highly diluted herbal preparations for digestive, nervous system, and circulatory support.
