Overview

Bovine bezoar is a gallstone that forms naturally in domestic cattle, gathered as a byproduct rather than an intentionally harvested part — a distinction worth stating plainly, since it means no animal is raised or killed specifically for it. The Donguibogam records it as a powerful mind-settling substance for states of fright, mania, and unconsciousness.

TranslationIts nature is neutral, its taste bitter, and it has slight toxicity. It settles the soul and calms the spirit, dispelling malign influence. It chiefly treats mania and fright palpitations, and sudden collapse, and treats the hundred illnesses of children.

Traditional functions

  • Calms the spirit, settles fright
  • Clears heat, resolves toxicity
  • Opens the sensory orifices
  • Traditionally used for pediatric convulsions

Traditional applications

  • Severe anxiety with fright and palpitations
  • Traditionally recorded for convulsions and unconsciousness
  • High fever with delirium (classical use)
  • Pediatric acute illness (classical use, specialist care required)

Traditional preparation

Traditionally used in minute doses (0.15–0.35g) as powder, never as a household decoction ingredient; formulated only by qualified practitioners.

Cautions

Caution: Genuine bovine bezoar is difficult to authenticate and counterfeit products are widely reported — use only through verified, legitimate medical channels. Traditionally contraindicated in pregnancy and in deficiency-cold patterns without true heat. This is a potent substance reserved for specific classical indications, always under professional supervision.

Frequently asked questions

Is using bovine bezoar an animal welfare or conservation concern?

No — it is a gallstone that forms naturally in some domestic cattle (Bos taurus, not an endangered species) and is recovered as a byproduct of normal cattle processing, not something an animal is specifically raised or harmed to produce.

Can I buy this and use it at home?

This is not a household herb. Genuine bezoar is rare, expensive, and frequently counterfeited; it is formulated in minute doses by qualified practitioners for specific acute conditions, not decocted at home like a typical herb.
