Panax notoginseng is a precious medicine town and an excellent variety of ginseng, which has unique functions. According to Li Shizhen's Compendium of Materia Medica in the Ming Dynasty, Tianqi is "slightly sweet and slightly bitter, quite like the taste of ginseng", and is known as "gold never changes". Zhao Xuemin wrote the Compendium of Materia Medica in the Qing Dynasty, saying: "Ginseng is the first to replenish qi, and Sanqi is the first to replenish blood, which has the same taste, so it is called Ginseng Sanqi, which is the most precious Chinese medicine." It is also recorded in Compendium of Materia Medica that Tianqi "is mainly used for stopping bleeding, dispersing blood and relieving pain, and treating arrow wound with golden blade." Those who fall on a stick and bleed profusely will chew it, or mix it at the end until the blood stops ",and" the South People's Army takes it as a medicine for golden sores "and says that" it is also mainly used for vomiting blood, bleeding, bleeding and insect bites. According to drug analysis, Panax notoginseng mainly contains six saponins, sitosterol, carotene and flavonoids. Saponins are the main components of ginseng, which play an important role in strengthening physical strength, improving myocardial oxygen metabolism and improving animal hypoxia tolerance. It is not empty talk in ancient medical books that Tianqi "takes ginseng as a contribution". Sitosterol and carotene can reduce blood lipid, while flavonoids are effective components to dilate coronary artery, improve myocardial blood supply and increase vascular elasticity. Therefore, regular consumption of Tianqi not only has a significant effect on coronary heart disease and angina pectoris, but also has a preventive effect on coronary heart disease and angina pectoris. It can prevent coronary heart disease, nourish and strengthen the body.
Tianqi should be used according to its purpose. Different administration methods have different effects. Generally speaking, Ascending to Heaven can make blood vessels contract, and it is a specific medicine for treating traumatic injury, which can really achieve the effect of hemostasis. Panax pseudo-ginseng made a paste with wine, and applied it on sores and gangrene to promote blood circulation and reduce swelling. The oral administration of Tianqi should depend on the condition: eat Tianqi raw, promote blood circulation, stop bleeding and relieve pain; To replenish blood and strengthen the body, you must eat cooked Tianqi. The preparation method of cooked Radix Notoginseng is to cut raw Radix Notoginseng into pieces, soak in salt water, dry in the sun, and grind into fine powder. Some people put raw notoginseng in a small bowl, which is filled with clear water. The amount of water is like this. You can suck the notoginseng dry, then steam it and slice it, fry it until it is yellow, crisp but not burnt, and then grind it into powder to make it mature. Both methods are acceptable. Cooked Tianqi has the functions of invigorating qi, promoting blood circulation, enriching blood, removing blood stasis and promoting regeneration. Tianqi stewed chicken is a good tonic for women to take after childbirth. On the famous menu in Guangxi, this is called "Tianqi Stewed Chicken". Soak the cooked Radix Notoginseng with Radix Notoginseng, Radix Codonopsis, Fructus Lycii, Cortex Eucommiae, etc. to obtain the "Radix Notoginseng tonic wine", which can replenish blood and qi, relax tendons and activate collaterals, promote human metabolism and improve health in the morning and evening, and is the top grade of medicinal liquor. In recent years, "Tianqi toothpaste" made from Tianqi has a good effect in preventing and treating dental diseases.
Panax notoginseng has a strong effect of removing blood stasis. It is said that a butcher killed a pig and got a big basin of pig blood. Because his hand was cut, he hurriedly took panax pseudo-ginseng and put it on the wound, and hurriedly sprinkled some panax pseudo-ginseng in the coagulated pig blood. Soon, pig blood turned into blood. Therefore, the method of identifying the authenticity of Panax notoginseng between sessions is often used to test blood clots. What can melt blood is true notoginseng, otherwise it is false notoginseng.
When buying Tianqi, you'd better buy a big, solid, slippery, claw-free one. Panax notoginseng is a perennial plant, which takes more than three years to harvest. The longer the planting period, the bigger the head and the better the quality. Therefore, the size of Panax notoginseng is based on how many heads (slices) there are per catty. For example, forty heads represent thirty-one to forty per catty, sixty heads represent forty-one to sixty per catty, and one hundred and twenty heads represent eighty-one to one hundred and twenty per catty; Folk classification is not so strict, 120 generally means no more than 130 per catty, and 80 means no more than 85 per catty. In short, the more people there are, the smaller Tianqi is, the less people there are, and the bigger Tianqi is. Notoginseng with twenty or forty heads generally needs to be planted for more than seven years, and it is the best of Notoginseng.
The processing of panax notoginseng should also be done well. After digging back, it should be washed and cut off (dried or used as medicine), exposed to the sun, and rubbed while drying until the roots are completely dry, leaving no traces of teeth. If it is processed to the final stage, the surface will be smoother and rounder if it is rubbed with a small board. In case of rainy weather, dry it with charcoal fire, and the firepower should be 30-35 degrees Celsius. There is also the need to turn over frequently, rub while baking, and don't turn off the fire in the middle, so as to avoid the phenomenon of "sweating back" when the temperature drops. A large number of panax notoginseng should be stored in a dry and ventilated place to prevent moisture, mildew or moth-eaten; A small amount can be stored in a sealed bottle for a long time.
