Look at the wild distribution areas: Polygonatum multiflorum wild wine is distributed in southern provinces (Anhui, Zhejiang, Jiangsu, Sunshine, Fujian, Jiangxi, Hunan, Hubei, Sichuan, Guizhou, etc.). Wild Camellia Polygonatum can be collected in this area. Look at the morphological characteristics of stems, leaves and roots. Polygonatum multiflorum is similar to Polygonatum odoratum, another Chinese herbal medicine, but it is obviously different from hypertrophic roots and Polygonatum odoratum. There are obvious differences between Polygonatum camelliforme and Polygonatum cristatum, with alternate leaves and Polygonatum cristatum in rotation. The leaves of Polygonum multiflorum Thunb are ovate-lanceolate, alternate, the flowers are umbels, yellow-white and light green, the flowering period is May, the fruit base is August11October, the fever is black, and the rhizome is thick and fleshy. Plants with many flowers and yellow essence are thicker and taller, which can reach 1 meter at most. Most of the wild grows under thin and humid forests and on shady slopes.

The flowering period is from March to May, and the fruit period is from 9 9- 10/October. The root fruit is relatively large and disc-shaped. Stems erect, prisms. Impeller students, 4 ~ 6 per round, full edge, no handle; Blade strip lightning rod shape. There are 2 ~ 4 flowers between the axils of peanut leaves, with the total pedicel lying prone and the flowers covered with yellow and white. Berries are nearly spherical and black when they are ripe. The roots and fruits are connected by a variety of conical knots, which are similar to the heads of chickens. Leaves alternate, elliptic, ovate or ovate. Umbrella with 2 ~ 7 flowers. The flowers are yellow-green, and the berries are black. They bloom in May and June, and bear fruit in August ~1October.

After cooking, Polygonatum sibiricum more or less retains its true color, appearing brown and black, and becoming a little yellow. Cut it out and it looks like strong coffee or strong earth color. Will not expose the overall darkness. If Polygonatum looks black, even with black mud, black powder and the like, and it is still turning black, you should pay attention. At present, in order to reduce the cooking time, some merchants add a certain amount of pigments or chemicals to achieve the purpose of rapidly discoloring Polygonatum. Therefore, when friends buy Polygonatum, it is best not to soak the water. If the water is black, don't drink it. Soak water in high-quality yellow still life, the color of water is brown, and the color of soup is clear. From the taste point of view, the high-quality roasted Polygonatum sibiricum with coriander is thick, soft, shiny, sweet and a little gritty. Many people responded that the Polygonatum I bought was not only dark in color, but also a little sour and bitter to eat. Some businessmen repeatedly apply hot compress with an electric stove for fake time, so Polygonatum polysaccharide may not spill out easily.
