Dandelion is recommended to be used in dried form when used as a traditional Chinese medicine, and in fresh form when consumed or used externally. Dandelion has the effects of clearing heat and removing toxins, eliminating swelling and dispersing lumps, inducing diuresis and clearing diuresis, and is mostly used for breast carbuncle and acute mastitis. First, fresh dandelion can be taken in decoction, or mashed juice for internal use, and the dregs can be applied externally to the affected area. Secondly, for gastritis caused by Helicobacter pylori infection, urinary tract infections caused by dampness-heat downstream, damp-heat jaundice, as well as the treatment of eye redness and swelling pain caused by liver fire, it is appropriate to use the dried product with other Chinese herbs. When used externally, the fresh product is more effective, and the amount of single product used is 9-15g, while the amount of fresh product used externally should be large, usually more than 30g, and it should be noted that the amount is too large and easy to lead to slow diarrhea. When dandelion is used in different ways, there are differences in its use.
