Dandelion is a commonly used herb in clinical practice. It belongs to the perennial herb family Asteraceae and has dandelion glycosides and dandelion esters, which have anti-inflammatory and anti-swelling properties and are commonly used in clinical practice for the treatment of inflammatory skin diseases. Dandelion can treat acne, but care should be taken to regulate its use. Acne is a common chronic, inflammatory skin disease in dermatology. Dandelion is more commonly used in acne identification, especially for patients with wind-heat in the lung meridian and damp-heat in the spleen and stomach, because of its anti-inflammatory and carbuncle-breaking effects, so it can be added when performing TCM identification in the clinic. However, the use of fresh dandelion for personal treatment is not recommended. In clinical practice, many mothers are found to use fresh dandelion for steaming and drinking for their children, but dried dandelion has a better therapeutic effect only after drying, and there are two sides to any drug, the positive effect of dandelion can be anti-inflammatory and the negative effect has some toxicity, so in the application of dandelion, it needs to be used in accordance with the regular hospital method.
