The medicinal rhubarb, known as southern rhubarb, is mainly produced in Sichuan, Hubei and other places. Rhubarb tastes bitter and cold. It belongs to the stomach, liver and large intestine. Its effective ingredients are anthraquinone compounds, including rhein, emodin, chrysophanol, aloe-emodin, emodin methyl ether, etc. It has the effects of scavenging oxygen free radicals, regulating blood lipids, anti-arteriosclerosis, anti-cancer, anti-aging, anti-psychotic, anti-bacterial and anti-inflammatory, protecting liver and gall bladder, and anti-virus.
1. It is used for dry stool, stagnant diarrhea, hot constipation, strong heat and yellow fur. It is compatible with mirabilite, Magnolia officinalis and Fructus Aurantii.

More than 130 compounds have been isolated and identified from various types of rhubarb, including anthraquinones and their glycosides, anthrones, diananthrones and their glycosides, stilbenes and their glycosides, gallates, naphthalene derivatives, chromanones and their glycosides, phenylbutanones, tannins, and so on. Among them, anthraquinones are important representative components. Free anthraquinones mainly include rhein, emodin, physcion, aloe emodin, chrysophanol, etc. Anthraquinone glycosides mainly include: chrysophanol 1-glucoside, chrysophanol 8-glucoside, emodin 1-glucoside, emodin 8-glucoside, emodin methyl ether 8-glucoside, emodin methyl ether 8-gentianoside, aloe emodin 8-glucoside, aloe emodin 3-glucoside, rhein 8-glucoside, and so on. Bianthrone glycosides include sennoside (Sennoside) A, B, C, D, E, F and so on. Stilbene and its glycosides include Rhaponticin, Rhapontigenin and De-oxyrhaponticin.
