Shodhana
Definition
The traditional ayurvedic purification process applied to aconite root and a few other toxic plant materials before therapeutic use. Boiling in cow's milk for several hours hydrolyses aconitine to less toxic aconine derivatives. Raw, unprocessed root remains highly lethal.

Common questions
Why does shodhana matter in a forensic toxicology case involving aconite poisoning?+
A death or illness following ingestion of processed, shodhana-treated aconite is far less likely to be fatal than one following raw root, so establishing whether the material consumed was purified or raw helps explain the clinical severity and can support or undermine a claim that a poisoning was accidental, ritual, or deliberate.
Does shodhana eliminate the toxic alkaloids entirely?+
No. It reduces toxicity by converting aconitine to less potent aconine-type compounds through hydrolysis, but it does not remove the alkaloids completely, so improperly processed or under-boiled material can still cause serious poisoning.
