Overview
Nux-vomica is one of the herbs traditionally used in Ayurveda for weakness & debility. Nux-vomica (Kupilu) is poison until Shodhana tames it: purified seeds, half to one ratti, ignite Agni, lift facial palsy, and steady stalled Vata nerves.
How Nux-vomica Helps with Weakness & Debility
According to Ayurvedic pharmacology, Nux-vomica has specific properties that make it valuable for addressing weakness & debility:
- Potency (Virya): Ushna (hot)
- Post-digestive (Vipaka): Katu (pungent)
- Taste (Rasa): Tikta (bitter), Katu (pungent)
- Qualities (Guna): Laghu (light), Tikshna (sharp)
Safety & Precautions
Nux-vomica is one of the few classical herbs where the safety section matters more than the benefits. The Bhavaprakash Nighantu is blunt: extreme caution is required.
- Toxic seeds: the dry seeds contain 1.25 to 1.5 percent strychnine, plus brucine, loganin and vomicine. The lethal dose of strychnine is very small.
- Never raw: the seeds are used only after purification (Shodhana), and only at a maximum of half to one ratti.
- Physician only: never self-medicate, even with products labelled as purified.
- Pregnancy, nursing and children: avoid completely.
- Heat: hot, sharp and pungent, it can aggravate Pitta.
If anyone swallows nux-vomica seeds or an unknown preparation, seek emergency medical care at once.
