Purified (shuddh) vs raw shilajit: why purification matters

What shodhana (purification) means, why raw shilajit can be risky, how purified resin looks and feels, and what to look for when buying.

Purified (shuddh) vs raw shilajit: why purification matters

Published 7 October 2026 · 3 min read

Ayurveda is very clear: shilajit must be purified (shodhita) before use. Raw (ashuddh) shilajit is not meant to be eaten.

Risks of raw shilajit

  • Heavy metals such as lead, arsenic or mercury from the surrounding rock
  • Microbes and fungal contamination
  • Sand, stones and plant debris
  • Mycotoxins if stored badly

What shodhana involves

Classical texts describe dissolving raw shilajit in hot water or herbal decoctions (triphala, dashmool and others), filtering, letting the solids settle, and drying the liquid layer slowly in the sun. The result is a clean, glossy resin. Modern manufacturers use similar steps plus filtration and lab testing.

Telling them apart

  • Raw: dull, rocky, crumbly, gritty, leaves sediment in water.
  • Purified: smooth, glossy, uniform resin; softens with warmth; dissolves almost completely in warm water.

What to buy

  • Labelled "purified" or "shuddh" shilajit from a licensed manufacturer
  • With a batch number and, ideally, a heavy-metal test report
  • Avoid loose, unlabelled shilajit sold by roadside sellers or "direct from the mountain" without testing

How to take shilajit (general guide)

  • Take a rice-grain to pea-sized piece of resin (about 300–500 mg) once a day, or follow your label dose.
  • Dissolve it in a cup of warm (not boiling) water or milk and stir for a minute or two.
  • Most people take it in the morning, after a light breakfast.
  • Start low in the first week and stop if it does not suit you.
  • Always use a clean, dry spoon so moisture does not get into the jar.
