Origin of panax notoginseng

Panax notoginseng originated from the remnants of tertiary paleotropical plants 250 million years ago. Panax notoginseng has special requirements for the growth environment, which is suitable for the climate of warm winter and cool summer, not tolerant of cold and heat, and prefers semi-cloudy and humid ecological environment. Therefore, its distribution range is limited to the narrow zone near the altitude of1500m-1800m in the southwest of China and 23.5 north latitude, including Wenshan prefecture in Yunnan Province and several places where Guangxi meets Wenshan. Wenshan Prefecture in Yunnan Province is the origin and main producing area. According to relevant documents, the history of Panax notoginseng is nearly 600 years, and its cultivation history is nearly 500 years.

Three-seven work efficiency

Effects of (1) on blood and hematopoietic system

Panax notoginseng has a good hemostatic effect, which can obviously shorten the bleeding and coagulation time; Can promote the division and growth of various blood cells, increase the number, and has obvious blood enriching effect; It has obvious curative effects of promoting blood circulation, removing blood stasis and promoting tissue regeneration.

(2) Effects on cardiovascular system

Experiments show that Panax notoginseng can obviously dilate blood vessels, reduce coronary resistance, increase coronary flow, strengthen and improve coronary microcirculation and increase nutritional myocardial blood flow, at the same time, it can reduce arterial pressure, slightly reduce heart rate and reduce cardiac workload, thus obviously reducing myocardial oxygen consumption, and can treat myocardial ischemia, angina pectoris and shock.

(3) Effects on nervous system

The aerial parts of panax notoginseng have inhibitory effects on the central nervous system, which are characterized by sedation, stability and sleep improvement. The underground part can excite the central nervous system, improve mental and physical strength, and show anti-fatigue; All parts of it are beneficial to enhance memory ability and have obvious analgesic effect.

(4) Anti-inflammatory effect

Panax notoginseng has obvious inhibitory effect on the increase of vascular permeability caused by many reasons and has strong anti-inflammatory effect.

(5) Functions of Panax notoginseng on immune system

Panax notoginseng saponins can significantly increase the phagocytosis rate and phagocytosis index of macrophages, increase the total number of white blood cells in peripheral blood and reduce the migration index of white blood cells. Panax notoginseng has certain immunomodulatory effect.

(6) Anti-tumor effect of Panax notoginseng

Notoginseng Radix contains anti-cancer active substances such as notoginsenoside, β-elemene and trace element selenium. Notoginsenoside Rh 1 has obvious inhibitory effect on cultured liver cancer cells; Notoginsenoside Rh2 has strong anti-tumor activity and can induce cancer cells to reverse to non-cancer cells.

(7) Anti-oxidation and anti-aging effects

It can significantly increase the activity of SOD in brain tissue and blood, and significantly reduce the content of lipid peroxide (LPO) in brain tissue and blood, and has anti-aging effect.

(8) Influence on substance metabolism

The effect of panax notoginseng saponins on blood sugar depends on the body's blood sugar level, which can increase or decrease blood sugar and has the function of two-way balanced regulation of blood sugar. It can affect blood lipid metabolism and reduce blood lipid level, especially the content of triglyceride is obviously reduced. Panax notoginseng can promote the synthesis of protein in liver, kidney, testis and serum, and promote the synthesis of deoxyribonucleic acid (DNA) in various organs and tissues.
