Panax pseudoginseng, also known as Tian Qi, was called “Jin Bu Chang” by Li Shizhen, a famous pharmacist in Ming Dynasty. It has the effect of dispersing blood stasis, stopping bleeding, reducing swelling and pain, and is used to treat hemoptysis, vomiting, epistaxis, blood in stool, leakage, bleeding from trauma, stabbing pain in the chest and abdomen, and pain from falling and swelling. The famous Chinese medicines “Yunnan Baiyao” and “Piece of Yellow” are made of Panax notoginseng as the main raw material. Wild panax pseudoginseng is rare and is now mostly cultivated. They are cultivated in Wenshan, Guangxi Wuzhou, Jiangxi and Sichuan, among which Wenshan has a long history and has a large yield and high quality as an authentic and valuable herb. So how to choose Panax ginseng correctly and reasonably? 1.Discern the authenticity. Genuine panax pseudoginseng is round-like or cylindrical, 2-5 cm long, 1-4 cm in diameter, with stem marks at the upper end, surrounded by verrucous protrusions, smooth surface, grayish brown or yellow, with interrupted longitudinal wrinkles and branch root marks. Body weight. Firm texture, the skin part is often separated from the wood part after breaking. The cross-section is gray-green, yellow-green or gray-white, with tiny brown resinous spots on the bark. The smell is slightly bitter, and then slightly sweet. In contrast, counterfeit Panax ginseng is mostly the dried rhizome of Curcuma longa or Curcuma longa of the ginger family, which is artificially carved to resemble Panax ginseng and is round or conical in shape. The surface is grayish yellow, with obvious ring-shaped nodes and carved knife marks, and the unsmooth surface is accompanied by white powder. The body is heavy, solid and hard to break, and the section is yellowish green or grayish brown. With horn-like waxy or with powder, the inner surface is ring-shaped, yellow-white, vascular bundle is dotted. When broken, the bark part is not separated from the wood part, with a strong pungent smell, slight pungent taste and light yellow powder. The efficacy of Panax notoginseng and other medicinal plants are different, so they should not be mixed with each other when used medicinally, and should be carefully identified. 2. On the head. Panax pseudoginseng is divided into 10 heads (within 500g-13 heads), 20 heads (within 500g-20 heads), 30 heads, 40 heads, 60 heads, 80 heads, 120 heads and so on according to its size, while the small ones are called numerous heads. Panax pseudoginseng is best for its large size, heavy quality, smooth body, brownish-black color, hard texture and grayish-green or yellowish-green color on the cross section. The larger the head of Panax notoginseng, the higher the price. Generally speaking, about 40 heads are more suitable for home use, but if you have good economic conditions, 20 heads are better. In addition, panax pseudoginseng is divided into slippery panax pseudoginseng and panax pseudoginseng with cap. 3. Purchase panax pseudoginseng powder. Panax pseudoginseng can be beaten into powder and swallowed. Panax pseudoginseng powder is available in many places, and the price difference is large. The quality of the whole pack of panax pseudoginseng powder is generally not too trustworthy, and no one dares to say how much panax pseudoginseng is in it. Generally, the medicinal value of Panax pseudoginseng powder above 80 heads is relatively poor. Therefore, I suggest that it is best to buy panax pseudoginseng slices and have them processed into powder by pharmacies, so as to ensure quality and facilitate preservation. For people with hypertension and hyperlipidemia, it is recommended to buy 10 or 15 heads of Panax pseudoginseng powder, and of course, 20 heads of Panax pseudoginseng powder can also be used. It is fine to use 40 heads of Panax pseudoginseng powder for beauty or Panax pseudoginseng powder for spot removal. If there are elderly people at home who need to eat panax pseudoginseng powder every day, 40 heads of panax pseudoginseng powder will do. The fineness of panax pseudoginseng powder depends on the machine and polishing process chosen. The finer the powder, the better, so that it is easier to absorb. The Panax pseudoginseng powder available in the market is below 200 mesh. At present, the finest Panax pseudoginseng powder includes Jin Bu Xie ultra-fine Panax pseudoginseng powder and Te An Na ultra-fine Panax pseudoginseng powder, which are produced by professional pharmaceutical companies specializing in cardiovascular and cerebrovascular diseases, and their fineness can reach more than 1200 mesh, which is the true meaning of ultra-fine Panax pseudoginseng powder with better effect. The above is a little bit of rough insight on how to buy panax pseudoginseng, I hope it can be helpful to you.
