Introduction
Rhubarb root has been used in Traditional Chinese Medicine for over 2,500 years and reached European medicine through the Silk Road trade in medieval times. The compound is among the oldest documented laxative herbs in continuous medicinal use globally.
Industrial production proceeds by ethanol and hot-water extraction of dried Rhubarb roots, followed by purification and standardization to defined anthraquinone content. Pharmaceutical-grade individual anthraquinones require chromatographic separation and crystallization.
Listed in EP, BP, and Chinese Pharmacopoeia as a pharmaceutical product. The European Medicines Agency has issued monographs for Rhubarb as a traditional herbal medicine for occasional constipation. Long-term use is contraindicated due to risk of dependence and electrolyte imbalance.
The anthraquinone compounds stimulate intestinal motility through direct action on the myenteric plexus, supporting the established laxative positioning. Individual anthraquinones (emodin in particular) have additional pharmacological activities under research for various therapeutic applications.
Strategic positioning combines traditional Chinese medicine product formulations, modern laxative and digestive supplements, and pharmaceutical research applications for isolated anthraquinones.
