" (2) Outline: "Where dodder is used, wash away the sand and mud with warm water, soak it in wine for one night, dry it in the sun and mash it. If not, soak it and mash it again, and we will know the details later. Another method is to soak the wine for four or five days, steam it for four or five times, grind it into cakes, cloud bake it, or dry it in the sun. When it is exposed, put a few pieces of paper in it and smash it together, and it will become powder immediately, saving effort. "
Textual research: from "Materia Medica": "Dodder soup, slightly fried and broken, if it is a pill, it must be carefully studied. Because it is difficult to grind people, I soaked in wine all night. Boil and spin silk, pound it into cakes, dry it and grind it, and finally it will be fine. However, if the wine is soaked for a long time, it will often turn sour and smelly, losing all the flavor of the fragrance. Every bubble is invalid. Now the tortoiseshell cakes on the market are all filled with wheat flour, and the fragrance is all good, so they must not be used. " (1) Bielu: "Dodder was born in Kawasawa, Korea. Spread on herbs, the color is yellow and thin, and it is a red net, which is light and tired. The moon is solid and violent. " (2) Tao Hongjing: "Dodder, many fields have fallen, all floating on Artemisia sphaerocephala. As the old saying goes, there is poria cocos under it and tussah on it, so it's not necessary today. "

Seed coat reddish brown or brownish yellow, slightly rough. Observation under a magnifying glass: there are fine dark spots on the surface, bright spots at one end and linear hilum in the center. Hard and not easy to break. There is no breath and the taste is slightly astringent. It is best to have complete particles without dust and impurities. Location: Liaoning, Jilin, Hebei, Henan, Shandong, Shanxi, Jiangsu and other places. ② The characters of Cuscuta chinensis are similar to those of the former species, but they are larger, with a long diameter of about 3 mm and a short diameter of about 2 ~ 3 mm Under the magnifying microscope, the surface of Cuscuta chinensis has irregular short-line markings.

Microscopic identification: ① Cuscuta australis powder: grayish yellow. (1) The seed coat cells are thin and yellow-brown, with two rows of cells in the cross section; Extracellular cells are 13 ~ 24 microns in radial direction and 4 ~ 9 microns in tangential direction, with thin walls and lignification; The inner row of grid cells is 32 ~ 56 microns in radial direction and 4 ~ 9 microns in tangential direction, with thick wall and no lignification, and the bright area is located on the upper part of the inner row of grid cells. On the surface, the cells are polygonal and slightly shrunk. ② The cross section of epidermal cells in seed skin is square, with a diameter of 19 ~ 37 microns, and the side wall is slightly thickened; The surface is round and polygonal.
