Description:
Rhubarb root (Rheum palmatum) is an essential ingredient in many old homemade ciders, wines and root beers. A strong decoction of Rhubarb root has a purgative action for use in the treatment of constipation, but also has an astringent effect following this. It therefore has a cleansing action upon the gut, removing debris and then astringing with antiseptic properties as well. Rhubarb root may color the urine yellow or red. Acording to Grieve's classic 'A Modern Herbal': Rhubarb is specially useful in infantile stomach troubles and looseness of the bowels. In fairly large doses it acts as a laxative.

Function:
1.Removing heat, constipation, treating abdominal distension and pain;
2.Improving blood circulation and treating amenorrhea;
3.Cooling blood and detoxification.
