Swarna Bhasma

Swarna bhasma — incinerated gold — is rasashastra’s most prestigious preparation: the rejuvenative (medhya rasayana) of kings’ medicine, claimed to enhance intellect, immunity, and longevity, and among the most-studied bhasmas in modern characterization research.

Overview

Gold leaf processed through shodhana (purification) and repeated marana (the calcination with mercury and herbal media — the classical puta cycles to the red? — the fine pink-brown ash); the pharmacopoeial tests (the fineness, the floatation, the luster tests); the classical dose (milligram-scale).

Therapeutic Claims

Medhya (intellect-promoting), rasayana (anti-aging, immunity), cardiac and nervous tonic; the formulations (Swarna prashana — the pediatric gold-ash rite of Pushya-nakshatra days; the Swarna bhasma compounds of the classical texts).

Modern Research

The best-characterized bhasma: TEM/XRD studies confirm nanoparticulate gold (the 2000s characterization corpus); immunomodulatory effects in animal models; the Swarna prashana clinical interest (immunity trials in children — early-stage); safety at pharmacopoeial doses favorable in studies, with the standard contamination caveats for market products.

Verification notes

• The nanoparticle characterization literature and classical preparation are documented; clinical claims remain preliminary.
• Audited against the Ayurvedic research literature (September 2026).
