Pashanabheda: Traditional Uses, Evidence, Dosage & Safety

TL;DR

Pashanabheda ("stone-breaker") is Ayurveda's traditional remedy for urinary stones, officially the rhizome of Bergenia ligulata: though 23 different plants trade under the name. One small open comparative trial (n=40) reported reduced stone size with a 60-day decoction, but there was no placebo group. Suspected kidney stones need medical evaluation, not self-treatment.

What it is

Pashanabheda, "stone-breaker" (pashana = stone, bheda = piercing), is the Ayurvedic drug used for urinary stones (mutrashmari, urolithiasis) (MDPI Bergenia review). The pharmacopoeial source is the rhizome of Bergenia ligulata Wall. (family Saxifragaceae; now often treated as Bergenia pacumbis): but the name is famously controversial: a review in AYU found 23 different plants traded as "Pashanbheda," with Aerva lanata as the official substitute and Ammania buccifera used under the name in Kerala (PMC). Key constituents include the polyphenols bergenin and arbutin (MDPI review).

Traditional use

Ayurvedic texts class pashanabheda as mutral (diuretic) and ashmaghna / ashmaribhedan (litholytic: stone-dissolving); Charaka places it in the Mutravirechaneeya group and Sushruta in Veertarvadi (Tyagi 2022). Traditional applications include urinary stones, piles, and abnormal leucorrhea (MDPI review). The classical energetics recorded for the root are light and unctuous qualities, astringent-bitter taste, pungent post-digestive effect, and cooling potency (Tyagi 2022). These are traditional claims, not clinical proof: the trial evidence is assessed separately below.

What modern research says

Urinary stones (comparative clinical study)

In a 2022 comparative clinical study, 40 patients with urolithiasis received a decoction of Bergenia ligulata or of Aerva lanata: 25 ml twice daily before meals for 60 days (Tyagi 2022). Mean stone size fell from 6.7 mm to 3.2 mm with B. ligulata and from 7.1 mm to 3.4 mm with A. lanata (raw means as reported; the paper labels these changes 47% and 46%); pain, hematuria, and burning urination improved in both groups. But the study was open-label with no placebo or standard-care arm and a small sample: improvement cannot be separated from natural stone passage or from the prescribed diet-and-water regimen all patients followed. A signal, not proof.

Bergenin and laboratory work

The MDPI review catalogues bergenin's reported properties, including antilithiatic effects, from laboratory and animal studies (MDPI review). Preclinical only.

What the evidence does not support (yet)

No large randomized, placebo-controlled trial of pashanabheda for kidney stones exists. "Stone-dissolving" claims rest on traditional use plus one small open study.

Dosage

In the comparative study, the regimen was a decoction prepared from 20 g of coarse dried-root powder boiled in 200 ml of water and reduced to 25 ml, taken twice daily before meals for 60 days: a research regimen, not a personal recommendation (Tyagi 2022).

Safety & contraindications

Human safety data are limited to the small, short study above, which did not detail adverse events. Because the market name covers many different species, product identity is a real concern: source from reputable manufacturers. Suspected kidney stones need medical evaluation first: obstruction or infection are emergencies, and self-treatment can delay care. Talk to a clinician first if you take diuretic medication or have kidney disease.

FAQs

What does pashanabheda mean?

"Stone-breaker": from pashana (stone) and bheda (piercing/breaking), reflecting its traditional use for urinary stones (MDPI review).

Which plant is the real pashanabheda?

The pharmacopoeia recognizes the rhizome of Bergenia ligulata as the official source, but 23 different plants are traded under the name; Aerva lanata is the official substitute, and southern India commonly uses it (PMC).

Does it dissolve kidney stones?

One small open study (n=40) reported mean stone size falling from 6.7 mm to 3.2 mm over 60 days of decoction use, but with no placebo group the traditional "stone-dissolving" claim remains unproven (Tyagi 2022).

How was it given in the study?

As a decoction, 20 g of coarse root powder boiled in 200 ml of water, reduced to 25 ml, taken twice daily before meals for 60 days (Tyagi 2022).

Is pashanabheda safe?

Dedicated safety data are essentially limited to one small short study. Get suspected kidney stones evaluated medically first: obstruction and infection are emergencies.
