Notoginseng is known as the "medicine for stopping bleeding", which can disperse blood stasis, stop bleeding without leaving blood stasis, and is more suitable for blood stasis bleeding. Panax notoginseng has a strong hemostatic effect, and it has obvious hemostatic effect on different animals, different routes of administration and different preparations. After notoginseng anesthesia, the coagulation time and prothrombin time of carotid blood in vitro were shortened. If the portal vein is ligated in advance, the hemostatic effect will disappear. It is speculated that after oral administration of Panax notoginseng, it must be metabolized by the liver to produce hemostasis. Intravenous injection of Notoginseng Radix in rabbits can shorten the clotting time, prothrombin time and thrombin time, increase the number of platelets and improve platelet adhesion. Intraperitoneal injection of Notoginseng Injection or intragastric infusion of Notoginseng Injection can shorten the bleeding time and coagulation time of mice. The hemostatic active component of Notoginseng Radix is Notoginsenoic acid. The bleeding time was measured by tail vein cutting method. intraperitoneal injection of notoginseng acid solution in mice could shorten the bleeding time and increase the number of platelets. Intravenous injection of dextran and thromboplastin in rabbits can cause different degrees of hemorrhage in interstitial lung and alveoli of rabbits, and at the same time, there are small thrombosis in small blood vessels and capillaries, resulting in a pathological model of bleeding and blood stasis. After the model animals were treated with Panax notoginseng injection, pulmonary hemorrhage and thrombosis were significantly reduced, which was very consistent with the theory of stopping bleeding without leaving blood stasis in traditional Chinese medicine. The hemostatic effect of Notoginseng Radix is mainly achieved by increasing the number of platelets and enhancing platelet function. Electron microscope observation showed that Notoginseng injection could make guinea pig platelets stretch pseudopodia, deform and aggregate in vitro, destroy and partially dissolve platelet membrane, and produce secretory reactions such as platelet degranulation, thus inducing platelets to release hemostatic active substances such as ADP, platelet coagulation factor III and Ca++, thus playing a hemostatic role. The hemostatic effect of panax notoginseng is also related to constricting local blood vessels and increasing thrombin content in blood. Panax notoginseng is easy to be destroyed by heating, so it is suitable for hemostasis.

So you see, the function of Sanqi is not to relieve exterior symptoms and dispel cold. If it is effective, it is also the divergent function of wine. Panax notoginseng itself belongs to the variety of ginseng, and exogenous diseases are not suitable for application.
