“Buckthorn is a popular European herb used widely as a mild laxative. It also contains alterative properties, has been recommended for rheumatism (to clear heat), and was one of the ingredients of the famous Hoxsey cure for cancer.
Other preparations: As a light decoction, 2-4 grams/dose, in the evening.

Buckthorn has a taste of BITTER, SWEET and a temperature of COLD.”

Buckthorn (Rhamnus spp.) has a long history of use and modern applications in herbal medicine, particularly for its laxative and purgative properties. Here’s a breakdown of its uses and scientific background:

Historical Uses

  • Traditional Medicine: Buckthorn, especially the bark, was traditionally used as a natural purgative and remedy for constipation. In ancient Europe, it was also used for treating liver issues and as an emetic (induces vomiting).

Modern Clinical Uses by Herbalists and Naturopaths

  • Laxative: Herbalists commonly use buckthorn bark for its mild to strong laxative effects. It works by stimulating bowel movement and is often recommended for chronic constipation.
  • Digestive Health: It is sometimes used to support digestive function and alleviate bloating and indigestion.

Chemistry and Pharmacology

  • Active Compounds: The primary active compounds in buckthorn are anthraquinones (e.g., rhein, emodin), which act on the intestines. These compounds stimulate peristalsis (the movement of the intestines) and increase the secretion of water into the colon, aiding in bowel movement.
  • Mechanism of Action: The anthraquinones bind to specific receptors in the colon, increasing motility and fluid retention to help alleviate constipation.

Clinical Trials

  • Efficacy: Clinical trials primarily focus on buckthorn’s efficacy as a laxative. Studies suggest that its effects are comparable to other herbal laxatives, though it is less studied than more commonly used options like senna or cascara sagrada.
  • Safety: Research also highlights safety concerns with prolonged use, especially regarding dependence and electrolyte imbalances.

Summary:

Buckthorn is mainly used today for its strong laxative effects, though caution is advised due to potential dependency and side effects. The clinical evidence supports its use as a short-term solution for constipation, though it is not commonly featured in large-scale clinical studies. Always use it under the guidance of a healthcare professional.
