Rhubarb

Christopher Hobbs:

“Rhubarb has bitter, laxative, and heat-clearing properties and is used for constipation, hemorrhoids, and gastroenteritis. It is also used for eruptive skin problems caused by faulty elimination and “damp heat” in the lower intestines.

Rhubarb has a taste of BITTER and a temperature of COLD.”

Historical Uses of Rhubarb

Rhubarb (genus Rheum) has been used for centuries in traditional medicine, particularly in China, where Rheum palmatum and Rheum officinale were prized for their purgative, laxative, and anti-inflammatory properties. It was also used to treat gastrointestinal disorders, liver conditions, and as a blood purifier in traditional Asian and European herbal practices.

Modern Clinical Uses

Herbalists and naturopaths use rhubarb for:

• Digestive health: Treating constipation and mild digestive disturbances.
• Liver health: Supporting detoxification and managing non-alcoholic fatty liver disease (in combination therapies).
• Kidney health: Reducing inflammation and protecting kidney function in patients with chronic kidney disease.
• Inflammatory conditions: Its anti-inflammatory properties make it useful for reducing systemic inflammation.

Chemistry

Rhubarb contains active compounds, including:

• Anthraquinones: Such as emodin and rhein, responsible for its laxative effects.
• Tannins: With astringent properties that help manage diarrhea when used in smaller doses.
• Flavonoids: Which contribute antioxidant activity.
• Sennosides: Potent laxative compounds, similar to those in senna.
• Calcium oxalate: Found in the leaves, which are toxic and not used medicinally.

Pharmacology

• Laxative effects: Stimulation of intestinal motility and water secretion via the anthraquinones.
• Anti-inflammatory effects: Rhein inhibits pro-inflammatory cytokines and pathways.
• Antimicrobial activity: Emodin shows activity against certain bacteria and fungi.
• Hepatoprotective: Antioxidant and anti-inflammatory effects protect liver tissues.

Clinical Trials

• Constipation: Studies have confirmed rhubarb’s efficacy as a laxative due to its anthraquinone content.
• Chronic kidney disease (CKD): Clinical trials suggest rhubarb may reduce creatinine levels and slow disease progression in CKD patients.
• Liver health: Studies support its use in managing non-alcoholic fatty liver disease through its antioxidant and anti-inflammatory properties.
• Cancer research: Preliminary studies indicate that emodin and rhein may have anticancer effects, though more research is needed.

Summary

Rhubarb has a long history of use in traditional medicine and remains a valuable herbal remedy for digestive and inflammatory conditions. Its active compounds have potent pharmacological effects, but safety concerns, especially regarding the toxicity of its leaves and prolonged use, should be considered. Ongoing clinical trials continue to explore its therapeutic potential in broader contexts, including liver and kidney health and cancer treatment.
