The alcoholic extracted tablets of rhubarb have been studied medically in this hospital for 10 years. They were divided into three groups, namely, Rheum officinale Baill, Rheum palmatum L, and Rheum tanguticum Maxim ex Balf. By using double-blind measurement of effect, the efficiencies of the groups appeared to be 90.7%, 93.7%, and 92.8% respectively. The time taken for the stool occult blood changing from positive into negative was 57.1, 53.4, and 56 hours respectively (P greater than 0.05). The medical difference is not significant. This shows that they are efficient in curing the upper digestive tract bleeding.
