Excuse me, how to distinguish gastrodia elata, thank you.

"Ying Ge's mouth is concave with navel, and there is a circle of dried ginger skin outside, and the rosin segment should be kept in mind." This is the formula for identifying Gastrodia elata. In this formula, rosin slice is an important basis for judging the authenticity of gastrodia elata. Specifically, after being harvested, Gastrodia elata is flattened, oblate, oval, shriveled and sometimes slightly curved, with a sharp and slightly curved reddish-brown bud at the top (commonly known as "Ying Ge mouth") and a round umbilical mark at the end (commonly known as "concave umbilical cord"). The surface is yellowish or yellowish brown, slightly transparent.

There are five common pseudo-gastrodia elata, namely, canna taro root, gastrodia elata, gopher, potato and chrysanthemum.

1. Banana taro root: Its rhizome is like Gastrodia elata, but it is connected, but its surface is covered with a layer of white powder, which is soft and easy to break, and its cross section is granular, white and dull.

2. Gastrodia elata: Its tubers are oval, some have been squashed, the tips at both ends are like horns, and there is a residual stem base at the top. The surface is grayish yellow, the links are obvious, there are irregular shrinkage cavities and grooves, and the quality is hard and tight, which is extremely difficult to break. The cross section is goat keratin-like, gray or yellow-white, and tastes slightly sweet.

3. Gopher: The original plant is an ornamental flower. After peeling and drying, the rhizome is conical, and both ends are often broken, with fibrous decapitation. The surface is yellowish or brownish yellow, with obvious longitudinal wrinkles and slightly sunken fibrous root marks. Under the magnifying glass, you can see that it is covered with tiny white crystals with no links. Hard, extremely difficult to break, its section is uneven, with a circular pattern at the center. The gas is slightly smelly, and the taste is light, which has the feeling of stinging the throat.

4. Potato: Its tuber is oval after steaming. The surface is yellow, with irregularly distributed concave bud roots, no point connection, flat section, horny and slightly regular.

5. Dali Chrysanthemum: The original plant is a famous flower. The processed root is spindle-shaped, the epidermis is gray or yellowish brown, there are wide longitudinal grooves, and the two ends are slightly pointed and fibrous. Hard, not easy to break, and its section is uneven. It tastes light and sticks to the teeth when chewed. This product is sometimes called "Sichuan peeled gastrodia elata" by mistake.

Gastrodia elata is mild in nature and has many functions, so people are happy to buy it back for home. For example, when buying in a farmer's market, the above identification method of Gastrodia elata can give you an important basis.
