Rhubarb root, derived from various Rheum species like Rheum palmatum, Rheum tanguticum, and Rheum officinale, has been used for centuries in traditional Chinese medicine. While commonly associated with culinary use in Western countries, where its red stems are used in pies and jams, rhubarb root plays a significant medicinal role, especially in China. This article explores what it is, its benefits, and potential side effects.
What Is Rhubarb Root?
Rhubarb root comes from plants belonging to the Polygonaceae family and is mainly used in herbal medicine. In traditional Chinese medicine (TCM), this root is often referred to as “Da Huang” and has been a key ingredient for over 2,000 years.
The root and rhizome are harvested, dried, and prepared for medicinal use. The active compounds found in the root include anthraquinones, tannins, and flavonoids, which are responsible for many of its effects on the body1.
Rhubarb root is valued for its bitter taste and is typically yellow or brown. When used medicinally, it has a variety of applications that range from digestive health to detoxification2.
Health Benefits and Medicinal Uses
Laxative Effect
One of the most well-known uses of rhubarb root is as a laxative. The active compounds, mainly anthraquinones, stimulate the muscles in the intestines to promote bowel movements3. This effect typically occurs within 6–10 hours after ingestion. For those suffering from constipation, this root offers a natural and effective solution4.
Example: If you’ve ever experienced bloating or discomfort from irregular digestion, rhubarb root can be a fast-acting remedy. Its ability to relieve constipation is why it’s often included in herbal formulas meant to clear intestinal blockages.
Anti-inflammatory and Antioxidant Properties
Rhubarb root contains tannins and flavonoids, which are known to have anti-inflammatory and antioxidant effects5. Studies have shown that these compounds can reduce inflammation and help protect the body against oxidative stress, which may lead to conditions like heart disease and cancer6.
Blood Purification and Detoxification
In TCM, rhubarb root is believed to help “cool” the blood, remove toxins, and improve circulation7. It has been traditionally used to treat conditions like high fever, infections, and abscesses8. The root’s detoxifying properties are linked to its ability to promote the removal of waste from the body, especially through the digestive tract.
Quick Tip: If you’re looking for a natural way to help your body detoxify, rhubarb root might be worth considering, but it’s essential to use it correctly and under guidance.

Liver and Gallbladder Support
Research suggests that rhubarb root may help stimulate bile production, which supports liver and gallbladder health9. Its ability to promote bile flow aids in digestion and the breakdown of fats, which is beneficial for those with gallbladder issues or liver congestion.
Anti-microbial and Anti-viral Effects
Rhubarb root also possesses anti-microbial properties, making it effective against various bacteria and viruses. Studies have found that it can inhibit the growth of bacteria such as Staphylococcus aureus and viruses like the influenza virus10.

Side Effects and Risks of Rhubarb Root
While rhubarb root offers a variety of health benefits, it’s important to be aware of potential side effects, particularly when used improperly or excessively.
- Digestive Discomfort Rhubarb root’s laxative effect, while helpful for constipation, can cause cramping, diarrhea, and abdominal pain if taken in excessive amounts. It’s recommended to start with small doses and increase only as needed11.
- Dehydration and Electrolyte Imbalance Prolonged use of this root as a laxative can lead to dehydration or an imbalance in electrolytes like potassium. This is particularly risky for older adults or those with pre-existing health conditions12. Pro Tip: If you use it as a laxative, ensure you stay hydrated and monitor your body’s response to avoid these side effects.
- Pregnancy and Menstrual Concerns Rhubarb root is not recommended for pregnant or breastfeeding women, as it may stimulate uterine contractions. Similarly, it should be used with caution during menstruation, as it could exacerbate cramping or increase blood flow13.
- Liver Toxicity Though rare, high doses of this root have been associated with liver toxicity. For this reason, it’s crucial to adhere to the recommended dosage, especially if used over long periods14.

How to Use it Safely
To avoid the potential risks associated with rhubarb root, it’s essential to follow dosage guidelines. In TCM, this herb is typically boiled into a tea or added to herbal formulas in quantities ranging from 3–12 grams for internal use. It can also be applied topically as a poultice for skin conditions or wounds15.
For digestive issues like constipation, it’s best to use rhubarb root in small doses and only as needed. If you’re considering using it for longer-term health benefits, consulting a healthcare provider is advisable.
Conclusion
Rhubarb root is a versatile herbal remedy with a long history of use in traditional medicine. From aiding digestion to fighting inflammation, its benefits are backed by both ancient wisdom and modern research. However, like all powerful herbs, it comes with risks. Always use this root responsibly, and consult with a healthcare professional if you plan to incorporate it into your wellness routine.
In summary, rhubarb root can be a powerful natural tool for your health—just be mindful of how you use it!
