What is rhubarb extract and why is it valuable?
Rhubarb (Rheum) is a plant with a millennia-long history of use in traditional Chinese and Ayurvedic medicine. The extract is mainly obtained from the roots, which contain a unique complex of active substances: anthraquinones (emodin, rhein), tannins, stilbene compounds, and calcium. This combination is responsible for a wide range of therapeutic properties.
At Tibetan Formula, we use a standardized rhubarb root extract at a concentration of 400 mg per tablet — this ensures a stable content of active substances in each dose. You can learn more about the product here: Rhubarb Extract 400 mg — 60 tablets by Tibetan Formula.
Scientifically proven properties of rhubarb extract
1. Digestion and intestines
Rhubarb anthraquinones (especially rhein and emodin) stimulate intestinal peristalsis, acting as a mild laxative for constipation. At the same time, in small doses, tannins provide a constipating effect — making rhubarb a unique plant with bidirectional action depending on the dosage.
Rhubarb also has a choleretic effect: it stimulates bile secretion and supports liver function, improving fat absorption and overall digestion. [PubMed: rhubarb anthraquinones and intestinal motility]
2. Relief of menopause symptoms
Extract of Siberian rhubarb (Rheum rhaponticum) contains raponticin — a phytoestrogen that interacts with estrogen receptors without hormone therapy. Clinical studies show that it:
- reduces hot flashes and night sweats by 50–73%
- stabilizes mood and reduces irritability
- improves sleep quality
- does not increase the risk of hormone-dependent diseases

3. Bone health
Rhubarb contains a significant amount of calcium — more than most leafy vegetables. This makes it relevant for postmenopausal women, when the risk of osteoporosis increases. Calcium combined with rhubarb phytoestrogens provides comprehensive support for bone tissue.
4. Cosmetics and skin
Rhubarb extract is widely used in cosmetics due to:
- Skin nourishment — antioxidants neutralize free radicals
- Texture restoration — stimulates collagen synthesis
- Evening out skin tone — natural lightening of pigmentation spots
- Moisturizing — for dryness and fine wrinkles
Important warnings
Despite its wide range of beneficial properties, rhubarb extract has clear limitations:
- Long-term use is not recommended — chronic intake may be toxic to kidneys and liver due to anthraquinone accumulation.
- Contraindicated in diarrhea, loose stools, or abdominal pain.
- Prohibited during pregnancy and breastfeeding.
- Always consult a doctor before use.
