Nux Vomica — from the Strychnos nux-vomica tree — is one of the most frequently prescribed remedies in modern urban homeopathic practice. It is the remedy of ambition, overwork, overstimulation, and the inevitable digestive and nervous collapse that follows a lifestyle of excess.
The Constitutional Picture
The Nux Vomica constitutional type is ambitious, driven, competitive, and irritable. They push themselves hard — at work, in relationships, in everything. They are quick-minded and quick-tempered. They cannot tolerate inefficiency, noise, light, or contradiction. The slightest affront triggers disproportionate irritability. They are often perfectionists who are highly critical of others and of themselves.
They tend toward excess: overwork, overeating, too much coffee, too much alcohol, too many stimulants. The body eventually rebels — through digestive disorders, headaches, insomnia, and heightened sensitivity to every sensation. The nervous system is wound too tight.
The Digestive Sphere
Nux Vomica's strongest clinical indication is in digestive complaints driven by overindulgence. Nausea with retching but inability to vomit — the stomach seems to want to empty but cannot. Constipation with constant ineffectual urging — the sensation that the bowel is trying to work but producing little result. Bloating and discomfort that is worst 1–2 hours after meals. Heartburn and acid reflux from rich food, spices, coffee, and alcohol.
The Nux Vomica patient is chilly — chilled easily, worse from cold, craves warmth and hot drinks. They are worse in the morning: morning nausea, worse after waking, sluggish before coffee. Better after a short sleep.

Nux Vomica in Modern Life
Nux Vomica is increasingly relevant in urban India — where demanding careers, irregular meals, late nights, high caffeine consumption, and constant stimulation are the norm. The remedy addresses not just the symptoms but the underlying nervous system state that drives the whole picture. With constitutional treatment, patients often find their tolerance for stimulants naturally decreases, their sleep improves, and their digestion normalises — without forcibly changing their lifestyle.
Nux Vomica 30 vs Nux Vomica 200: Uses and Differences
Nux Vomica is the classic remedy for the over-stimulated, over-worked person — and for the digestive upsets of rich food, late nights, coffee and alcohol. It is used most often in 30C and 200C.
Nux vomica seeds contain strychnine. Only properly potentised homeopathic preparations are safe; the crude substance, mother tincture and very low potencies must never be self-administered.
| Potency | Generally used for | How it is usually used |
|---|---|---|
| Nux Vomica 30 | Acute digestive upset after overeating, spicy or rich food, coffee or alcohol; constipation with frequent ineffective urging; heaviness and irritability after a late night. | Commonly used for short-lived, recent complaints, for a short period as advised. |
| Nux Vomica 200 | Constitutional treatment of the driven, irritable, chilly person with chronic acidity, constipation, stress-related sleeplessness (often waking around 3am) and dependence on stimulants. | Given infrequently and normally chosen by a homeopath after a full consultation. |
This is general materia medica information, not a prescription. Potency, dose and how often to repeat it should be set by a qualified homeopath after a full case assessment.
Using homeopathic medicines safely
Keep medicines out of reach of children. Store them in a cool, dry place, away from direct sunlight and strong smells such as camphor, menthol or perfume. Don't exceed the dose or frequency your homeopath advises, and seek advice if symptoms get markedly worse.
Nux Vomica: Frequently Asked Questions
What is Nux Vomica 30 used for?▾
Nux Vomica 30 is traditionally used for acute digestive upset after overeating, rich or spicy food, coffee or alcohol — nausea, heaviness, acidity — and for constipation with frequent but ineffective urging. The right potency and how often to take it depend on your full case, so a qualified homeopath should decide this.
What is Nux Vomica 200 used for?▾
Nux Vomica 200 is generally used constitutionally for long-standing patterns in a driven, irritable, chilly person — chronic acidity and constipation, stress-related insomnia and reliance on coffee or other stimulants. It is used infrequently and chosen by a homeopath.
What is the difference between Nux Vomica 30 and 200?▾
30 is more often used for recent, short-lived complaints and may be repeated for a short period; 200 is used for deeper, long-standing patterns and repeated far less often.
Does Nux Vomica have side effects?▾
Potentised Nux Vomica is highly diluted and generally well tolerated; a brief flare of existing symptoms can occur. The crude seed is poisonous, so only proper homeopathic potencies should be used. Persistent vomiting, blood in vomit or stool, or severe abdominal pain needs a doctor.
Your body is not built to run on caffeine and willpower forever.
Constitutional homeopathy addresses the underlying nervous system exhaustion — the reason the digestive system, sleep, and irritability all collapse at once. Let's find your pattern.
