Rhubarb extract powder is the dried root and rhizome extracts of the Polygonaceae plant rhubarb, tangute rhubarb or medicinal rhubarb. Palm-leaf rhubarb and Tanggut-rhubarb medicinal materials are called northern rhubarb, and are mainly produced in Qinghai, Gansu, Sichuan and other places. The medicinal material of rhubarb is called southern rhubarb, which is mainly produced in Sichuan, Hubei and other places. Rhubarb is bitter and cold in taste and returns to the stomach, liver and large intestine meridians. The active ingredients are anthraquinone compounds, including rhein, emodin, chrysophanol, aloe-emodin, emodin methyl ether, etc., which can scavenge oxygen free radicals, regulate blood lipids, and resist aging. , antibacterial and anti-inflammatory, liver and gallbladder protection, antiviral and other effects. More than 130 compounds have been isolated and identified from various rhubarbs, including anthraquinones and their glycosides, anthrones, dianthrones and their glycosides, stilbene and their glycosides, gallic acid esters, and naphthalene derivatives , chromanone and its glycosides, phenylbutanone, tannins, etc. Among them, anthraquinones are important representative components.

1. Sennoside is decomposed under the action of intestinal bacterial enzymes to produce rhein anthrone, which can stimulate the mucosa of the large intestine, increase intestinal peristalsis and cause diarrhea. It increases the osmotic pressure in the intestine, retains a lot of water, and promotes peristalsis and diarrhea.
2. The hemostatic effect is exact and the effect is quick. The mechanism of action is to promote the adhesion and aggregation of platelets; increase the number of platelets and the content of fibrinogen; constrict the blood vessels in the injured area.
3. Rhubarb extract has the effect of blood dilution, which may be through the effect of plasma osmotic pressure to promote the transfer of extracellular fluid into the blood vessels, thereby diluting the blood, resulting in the reduction of blood cells and the decrease in blood viscosity, thereby enhancing microcirculation and achieving blood circulation. the goal of.
4. It has inhibitory effect on a variety of Gram-positive and negative bacteria in vitro, especially sensitive to paratyphoid bacillus and dysentery bacillus.
5. It can play a cooling effect, and the cooling is stable, and there is no adverse reaction such as profuse sweating or collapse.
6. There is a two-way regulation effect on the immune function, there are different degrees of immunosuppression, and it has inhibitory or blocking effects on cellular immunity and humoral immunity.
7. The tannin contained in rhubarb has a very good antioxidant effect.
