Concerns

What it does

Nux vomica is reserved for extreme cases: severe pain, numbness, and paralysis that nothing else can reach. It contains strychnine, making it one of the most dangerous substances in TCM. Practitioners use it only when gentler approaches have failed, for conditions like hemiplegia and rheumatoid arthritis. The therapeutic window is extremely narrow, and even tiny overdoses can be fatal.

How to take it

Capsule

Only used in micro-doses within practitioner-prescribed formulas after strict processing. Never handle or prepare raw nux vomica seeds.

Where it comes from

Nux vomica comes from the Strychnos tree and contains strychnine, one of the most famous poisons in history. In TCM, it's been used cautiously for centuries for conditions where severe pain and paralysis resist all other treatment. The processing involves sand-frying or oil-frying the seeds to reduce toxicity. Even after processing, the therapeutic window is extremely narrow. It represents TCM's principle that the most dangerous substances, used precisely, can treat what nothing gentle can.
