Prabhakara Vati: Cardiac Formula, Evidence & Safety

TL;DR

Prabhakara Vati is a classical Ayurvedic cardiac formula: five mineral preparations including iron and mica bhasmas plus shilajatu and bamboo manna, triturated with arjuna bark decoction. Evidence is preliminary: one small 2017 single-blind study reported symptom and blood-pressure improvements, and a 2025 case report combined it with many other therapies. It is not proven to treat heart disease.

What it is

Prabhakara Vati is a classical herbo-mineral Ayurvedic formulation referenced in the Bhaisajya Ratnavali (Hridroga Prakarana: the chapter on heart disorders) and the Ayurvedic Formulary of India (Part I). A 2025 pharmaceutical study that prepared it at the Government Ayurveda College, Thiruvananthapuram, documents the formula: equal parts of Shuddha Abhraka Bhasma (purified mica calx), Shuddha Loha Bhasma (purified iron calx), Shuddha Swarna Makshika Bhasma (purified copper-iron-sulfide calx), Shuddha Shilajatu (purified mineral pitch) and Tugaksheeri (bamboo manna): triturated (bhavana) with a decoction of Terminalia arjuna bark (preparation study, IJAPR 2025). The same study details the classical purification (sodhana) and incineration (marana) of each bhasma and quality checks (bhasma pareeksha) before the final trituration.

Traditional use

Classical Ayurveda positions Prabhakara Vati within the hridroga (heart-disorder) repertoire of the Bhaishajya Ratnavali, and a 2023 review of classical rasaushadhi for hridroga lists it among the formulations of that tradition (classical-texts review, IJCRT). These are records of traditional practice, not clinical proof: the human evidence is assessed separately below.

What modern research says

The 2017 clinical study (small, single-blind, no control arm)

The most direct clinical evidence is a 2017 single-blind study published in the International Ayurvedic Medical Journal: 50 patients with Hriday Roga (aged 20–70, recruited from a Lucknow Ayurvedic college hospital; 60 registered, 50 completed) took two vati twice daily with lukewarm water for 3 months, with fortnightly follow-up (Shukla et al. 2017). The authors reported statistically significant improvements in cardiac symptom scores (mostly p<0.001), reductions in systolic and diastolic blood pressure, changes in ECG intervals, and improved lipid measures (for example, in the kaphaja-prakriti subgroup: total cholesterol 290→180, triglycerides 240→150, HDL 35→42, LDL 194→114 mg/dL).

Read the limits carefully: the study had a single treatment group with no control or placebo arm, so improvements cannot be separated from placebo effects or natural course. It was small and single-blind; and the paper reports the dose as "two vati" without stating the tablet mass: so no standardized dose can be taken from it.

The 2025 case report (multimodal — cannot isolate the vati's effect)

A 2025 case report in the Journal of Clinical and Diagnostic Research described a 35-year-old man with post–myocardial-infarction heart failure whose left ventricular ejection fraction rose from 30–35% to 45–50% after 40 days of an integrative regimen (case report). Prabhakara Vati (2 tablets of 250 mg twice daily) was one element among many: continued allopathic cardiac drugs, an arjuna–ashwagandha–haritaki–haridra–punarnava decoction, arjunarishta, sarak vati, and multiple external oleation, fomentation and enema procedures. With so many simultaneous interventions, the improvement cannot be attributed to Prabhakara Vati.

Pharmacological rationale (review-level, not clinical proof)

A 2024 review discusses the traditional pharmacological rationale ingredient by ingredient: suvarnamakshika bhasma for palpitation, loha bhasma for cardiac edema and breathlessness, abhraka bhasma for dyspnea and irregular pulse, arjuna for hridroga (review, WJPPS). This is a discussion of classical rationale, not evidence that the formulation works in patients.

Bottom line on the evidence

The evidence is preliminary, small and methodologically weak. It does not establish that Prabhakara Vati prevents or treats heart attack, heart failure, angina, arrhythmia or hypertension in humans. Classical cardiac use is not proof of efficacy.

Safety & contraindications

FAQs

What is Prabhakara Vati?

Prabhakara Vati is a classical Ayurvedic herbo-mineral tablet for heart disorders, referenced in the Bhaishajya Ratnavali's Hridroga chapter and the Ayurvedic Formulary of India. It combines five ingredients in equal parts, purified mica, iron and copper-iron-sulfide bhasmas, shilajatu and bamboo manna, triturated with Terminalia arjuna bark decoction. A 2025 pharmaceutical study documented its step-by-step classical preparation. (Source)

Does Prabhakara Vati treat heart disease?

Not proven. The best available evidence is a small 2017 single-blind study (50 patients, no control group) that reported improved cardiac symptoms, blood pressure, ECG measures and lipids over 3 months: but without a control arm these results are preliminary. A 2025 case report combined the vati with many other treatments, so its individual effect is unknown. It is not established to prevent or treat heart attack, heart failure, angina or hypertension.

What did the 2017 clinical study actually find?

In 50 Hriday Roga patients taking two vati twice daily for 3 months, the authors reported statistically significant improvements in cardiac symptom scores, lower systolic and diastolic blood pressure, ECG interval changes, and better lipid values (e.g., total cholesterol 290→180 mg/dL in one subgroup). The study was single-blind with a single treatment group and no placebo: so the findings are suggestive, not conclusive. (Source)

Can Prabhakara Vati replace my heart medicines?

No. Nothing in the evidence supports replacing prescribed cardiac medicines with Prabhakara Vati, and doing so could be dangerous. In the 2025 case report, the patient continued all standard allopathic cardiac drugs throughout the Ayurvedic treatment. Any combined use must involve both your cardiologist and a qualified Ayurvedic practitioner.

What is the correct dose of Prabhakara Vati?

No verified standard dose exists. The 2017 study used "two vati twice daily" without reporting tablet mass, and the 2025 case report used 2 tablets of 250 mg twice daily as part of a multi-therapy regimen: different products, different contexts. Dose must be set by a qualified Ayurvedic practitioner for the specific product in hand, never self-determined.

Is Prabhakara Vati safe?

Its safety profile is not well characterized. It contains calcined metal/mineral preparations, so product quality and batch testing matter; interactions with heart medicines are unstudied; and there are no adequate safety data for pregnancy or breastfeeding. It should be used only under qualified practitioner supervision, alongside, never instead of, standard cardiac care.
