Shukti Bhasma: Traditional Uses, Evidence & Safety
TL;DR
Shukti Bhasma is a calcined preparation of pearl oyster shell: a sudha varga (calcium-group) mineral medicine of Rasashastra. Classical texts use it for acidity, post-meal pain, and meal-related abdominal pain. The modern record holds exactly one experimental study: a rat model of aspirin-induced gastric ulcer in which the bhasma showed significant anti-ulcer activity, even compared with the standard drug sucralfate. No human trials exist.
What it is
Shukti is oyster shell. Mukta Shukti is specifically pearl oyster shell. In Rasashastra it belongs to sudha varga, the group of calcium-bearing drugs. After proper purification (shodhana) and calcination (marana), it attains its therapeutic properties. That is per classical pharmacy texts such as the Rasatarangini, which Sreejith's 2012 study followed for its preparation (Sreejith, 2012).
Elemental analysis (atomic absorption spectroscopy) of the raw shell and the finished bhasma detected calcium, magnesium, manganese, iron, potassium, aluminum, copper, sodium, and zinc. X-ray diffraction showed face-centered cubic, hexagonal, tetragonal, and monoclinic crystal structures (Sreejith, 2012). Chemically, then, this is essentially a multi-mineral calcium preparation. That matters when interpreting its reported stomach effects.
Traditional use
Classical texts indicate Shukti for Amlapitta (sour, burning dyspepsia), Parinamashoola (pain during digestion), and Annadravashoola (pain associated with food or liquids): the acid-peptic spectrum of Ayurvedic nosology. The 2012 paper notes Acharya Sushruta's association of amla (sourness) with vitiated vidagdha pitta, and correlates Amlapitta broadly with acid-reflux syndromes including gastritis and peptic ulcer (Sreejith, 2012). These are traditional attributions; what follows is the only modern test of them.
What modern research says
Animal experiment: aspirin-induced gastric ulcer in rats
In the only study located, Mukta Shukti Bhasma was tested in albino rats with aspirin-induced gastric ulcers, with sucralfate as the standard-drug group and food/water as the control group. The bhasma showed highly significant anti-ulcer activity compared with the control. In this model, it outperformed the sucralfate group as well. The author attributed the effect to the preparation's alkaline pH and mineral components, hypothesizing inhibition of gastric secretions, neutralization of acidity, and reduction in ulcer lesion size (Sreejith, 2012).
This is a real experimental result. But its limits are plain. It is a conference abstract, not a full paper. It reports no sample sizes, randomization method, or blinding. It is a single animal model. And the author himself concluded only that the finding gives "scope for conducting clinical study." No such human study was found.
What the evidence does not support (yet)
- No human trials. The anti-ulcer effect has never been tested in people.
- No mechanism confirmation. The alkaline-pH/secretion-inhibition explanation is the author's hypothesis, not a demonstrated mechanism.
- No data on other traditional uses (post-meal pain, general dyspepsia) beyond the single rat ulcer model.
Safety & contraindications
No human safety data exist. What the record does establish:
- Calcium-rich mineral medicine. Like all bhasmas, its safety depends entirely on proper shodhana (purification) and marana (calcination). This is not a preparation to buy casually or make at home.
- Plausible interaction territory. Anything that alkalinizes the stomach or delivers calcium could interact with acid-suppressing drugs, thyroid medication, iron, and some antibiotics. No interaction studies exist for Shukti Bhasma specifically.
- No data on pregnancy, breastfeeding, children, or long-term use. Traditional guidance assumes use under a qualified practitioner's supervision.
FAQs
What is Shukti Bhasma made of?
Calcined pearl oyster shell: a sudha varga (calcium-group) drug of Rasashastra, prepared through classical purification and calcination per texts like the Rasatarangini.
Does it treat stomach ulcers?
In rats with aspirin-induced ulcers, one study found significant anti-ulcer activity. That is the entire modern record. No human trial has been conducted, so no efficacy claim in people can be made.
Why is there only one study?
Most bhasma research goes toward preparation standardization and basic pharmacology. Clinical trials of classical bhasmas for specific indications remain rare. The 2012 paper itself ended by calling for exactly such a study.
What is the recommended dose?
Our editorial rule requires a pharmacopoeial or clinical-trial dose. None exists for Shukti Bhasma in the available sources, so we state none. And we do not repeat the milligram figures found on commercial sites, which are not evidence-based.

This article is for educational purposes only and is not medical advice. Shukti Bhasma has been tested only in one animal model, with no human trials and no established safety profile. Like all bhasmas, it is a mineral preparation whose safety depends on proper classical purification and calcination.
