Pravala Pishti

Pravala Pishti is a bhasma, a mineral or metal preparation reduced to ash by repeated calcination. [Effect of Praval bhasma (Coral calx), a natural source of rich calcium on bone mineralization in rats](https://pubmed.ncbi.nlm.nih.gov/14527824/).

How does it work?

  • Calcium supplementation: CaCO3 from coral provides bioavailable calcium for bone mineralization; the marine-derived form may have superior absorption compared to geological calcium carbonate due to trace mineral co-factors
  • Acid-neutralizing antacid: Calcium carbonate directly neutralizes excess gastric HCl, providing rapid relief from hyperacidity - mechanistically identical to pharmaceutical antacids
  • Pitta-pacifying and hemostatic: The cooling property reduces Pitta-related bleeding disorders; calcium is essential for the coagulation cascade, supporting the traditional use in bleeding conditions

Which traditional uses are supported by research?

  • Calcium deficiency and bone disorders: Preclinical study (2003) demonstrated prevention of calcium and estrogen deficit bone loss; multicenter clinical study (2020) supported safety and efficacy in menopausal calcium management
  • Hyperacidity (Amlapitta) and bleeding disorders (Raktapitta): The calcium carbonate content provides direct mechanistic validation for antacid use; calcium’s role in coagulation cascade supports the traditional hemostatic indication

What do recent clinical trials show?

Recent safety updates

  • GENERALLY SAFE: Like Mukta Pishti, Pravala Pishti is a non-toxic mineral preparation containing no heavy metals when properly prepared - essentially a natural coral calcium supplement
  • Dose-dependent side effects: Excess intake (>2500 mg/day) can cause abdominal distension, flatulence, loss of appetite, and risk of kidney stone formation due to hypercalcemia
  • Environmental concern: Coral harvesting raises ecological sustainability questions; sourcing from sustainable or cultivated coral stocks is recommended
  • Quality control: Marine-derived products should be tested for marine pollutants, microbiological contamination, and heavy metal residues; GMP-certified sourcing essential

What is it made of?

Mineral/Elemental Profile

  • Primary component: Calcined mineral/metal oxide (after Shodhana and Marana)
  • Particle size: Sub-micron to nanoparticle range
  • Note: Exact composition depends on source material and preparation method

Analytical Methods: XRD, ICP-OES/ICP-MS, SEM-EDS, Particle size analysis, Namburi phased spot test

Dosage forms and preparation

Dosage Forms: Pishti, Bhasma (Pravala Bhasma also available)

Standard Dosage: 250–500 mg twice daily

Bioavailability: Excellent; coral calcium carbonate with natural marine mineral matrix — one of the most bioavailable calcium forms

Optimal Timing: With honey or Malai; with meals for calcium supplementation

Standardized Extract: Red coral pishti — cold-processed coral calcium

Shelf Life: Indefinite

Storage: Airtight, dry container

Marker Compounds: Calcium carbonate (85–90%), Magnesium (2–3%), Strontium, Iron, Trace elements (70+ from marine origin)

Quality Parameters: Calcium >30%, magnesium >1%, standard pishti tests, coral authentication (not synthetic), marine pollutant screening

Vehicle (Anupana): Honey, Gulkand, Malai, or pomegranate juice

Published research

Literature indexed in PubMed that concerns this subject, grouped by study type. A paper appearing here is a record of what has been published, not evidence that the subject works, and laboratory or animal results do not transfer to people. Study titles link to PubMed so you can read the source rather than take our word.

Consult a qualified vaidya before acting on anything here. Ayurvedic practice is prescribed to a person, not to a condition: the same dravya is given, withheld or substituted depending on your constitution, your agni, the season and what else you are already taking. A page cannot know any of that. Self-prescribing from a reference is how the wrong preparation, the wrong dose or the wrong anupana gets used.

Educational reference only. Nothing on this page is medical advice, a diagnosis, or a recommendation to take anything. Traditional uses and research findings are reported as published, not as claims about what any product does.
