There is no distinction between dandelion root and dandelion leaf in medicine. Dandelion is actually used in medicine in the form of the whole herb, that is, at the time of picking, dandelion root and leaf are actually picked together, and then dried in the sun for medicine. However, the leaves of dandelion are relatively thin, so the active ingredients are relatively easy to dissolve once boiled. The root tends to be more dense, so the root is more resistant to soaking, the effective ingredients may not be soaked once, need to be repeated many times to soak, cook to cook out, but the two drugs in the function is not any distinction.
