I didn't know how to identify whether Radix Codonopsis and Radix Astragali were smoked with sulfur. Later, under the introduction of a friend, I consulted the "Western Top Class Hall" in Taobao shop and taught me how to be smoked with dangshen sulfur:
Some time ago, I consulted the Western Region Shangpintang, because all their codonopsis pilosula originated from the "hometown of codonopsis pilosula in China", which is a natural and original ecological cultivation, unlike traditional Chinese medicine markets or hospitals, which are all smoked with sulfur. "Western Top-grade Soup" taught me to tell whether Codonopsis pilosula was smoked with sulfur;
Color (1): Codonopsis pilosula smoked with sulfur turns yellow unnaturally, especially at the roots, because many of them are washed and bleached with washing powder before sulfur fumigation to prevent sulfur from being smoked on the soil, and the "good-looking" effect of sulfur fumigation will be lost after falling off the soil; The color of Codonopsis pilosula without sulfur fumigation is khaki or khaki, that is, it is also natural khaki or khaki after being washed with clear water.
(2) Taste: Sulfur smoked Codonopsis pilosula has a pungent sulfur smell, which is related to the severity and time of sulfur smoked Codonopsis pilosula. The greater the sulfur smoke, the closer the time, and the more obvious the pungent smell; It's not sulfur, it's earth, and there's no pungent smell.
(3) Taste: Because there is monomer sulfur in sulfur-smoked Codonopsis pilosula, it tastes unnatural sour; There is no smoked codonopsis pilosula, which is fragrant and sweet.
(4) Storage: Generally, it will not breed after being smoked for half a year, and some of them can't be seen as old goods even after being stored for 2-3 years, but they are not smoked with sulfur. In a hot and humid climate, it is easy to breed, mold and rot. So put it in the refrigerator!
I bought Codonopsis pilosula several times in the Taobao shop "Western Region Shangpintang", and I was very satisfied. No problem. Their codonopsis pilosula is sold directly on the Internet from the place of origin, without going through the medicinal material market, so the quality is guaranteed.
