Role of Gomutra in the Shodhana of Vatsanabha

Vatsanabha (Aconitum ferox) is classified under Mahavisha due to the presence of aconitine alkaloids which cause severe toxic effects. However, when purified using the classical Shodhana procedure, its toxicity is significantly reduced while retaining its therapeutic actions. Gomutra (cow’s urine) is described as one of the most effective Shodhana dravyas for Vatsanabha. This article highlights the rationale, method, and classical references supporting the use of Gomutra in Vatsanabha Shodhana.
