Himalayan Rhubarb

BotanicalBest before bed

What is it

Himalayan rhubarb refers most often to Rheum australe or Rheum emodi (chopchinee in Hindi), used in Ayurveda and traditional Tibetan medicine as a laxative, liver tonic, and for skin and inflammatory conditions. Note that 'chopchinee' is sometimes confused with Smilax china, which is unrelated.

Evidence for 2 uses

AI-assisted evidence assessment — talk to your doctor before relying on any single supplement.

Constipation (short-term)

Good Evidence

Anthraquinone-containing Rheum extracts are effective stimulant laxatives, similar to senna.

Liver support (traditional)

Mixed Evidence

Used in traditional medicine for liver conditions. Animal studies suggest hepatoprotective activity; human evidence is limited.

How it works

Like other Rheum species, Himalayan rhubarb root contains anthraquinone glycosides (sennosides, emodin, rhein, aloe-emodin), tannins, and stilbene compounds. The anthraquinones provide a stimulant laxative effect through irritation of the colonic mucosa, while tannins provide an opposing astringent effect. Liver-protective and anti-inflammatory activities are reported in animal studies.

Dosage

Traditional doses use 1 to 3 grams of root powder daily. Modern standardized extracts vary.

When and how to take it

Laxative effect typically occurs 8 to 12 hours after ingestion; usually taken at bedtime for morning bowel movement. Not for long-term use.

Rhubarb root powder

Traditional preparation; effects in 6 to 12 hours.

Anthraquinone glycosides activated by colonic bacteria.

Standardized rhubarb extract

Capsules for digestive support.

Variable potency.

Safety

Can cause cramping, electrolyte loss (especially potassium) with long-term laxative use, and red-orange urine. Long-term use of anthraquinone laxatives is associated with melanosis coli, dependence, and possibly increased colon cancer risk. Rhubarb leaves contain oxalic acid and are toxic; only roots and stalks are used.

Who should be cautious

Avoid in pregnancy (uterine stimulant) and breastfeeding (anthraquinones can pass into breast milk and cause infant diarrhea). Avoid in children, intestinal obstruction, severe dehydration, and chronic kidney disease (oxalates).

Interactions

Potassium loss from laxative effect can potentiate digoxin toxicity and other potassium-sensitive drugs. May reduce absorption of medications taken concurrently. Theoretical interaction with anticoagulants.
