Whether to take Xiao Jin Wan or Free Pill for breast nodules should be determined by the clinician’s diagnosis. If breast nodules are caused by liver-qi disharmony, Free Pill is better, while Xiao Jin Wan is better for breast nodules caused by phlegm-qi stagnation. Xiao Jin Wan has the efficacy of dredging the liver and regulating qi (regulating the stagnation of liver qi), strengthening the spleen and harmonizing the stomach (restoring the functions of the spleen and stomach), and nourishing blood and regulating menstruation (regulating menstrual irregularities caused by blood deficiency). It is clinically used for treating dizziness and dizziness caused by Liver-Qi disharmony, irregular menstruation, distension and pain in the chest and ribs, and loss of appetite. If the breast nodules are caused by liver-qi disharmony, it is better to use Puan Yuan, but the specific circumstances should follow the advice of the clinician. Xiao Jin Wan has the efficacy of subduing swelling and dispersing nodules, resolving blood stasis and relieving pain. Clinically, it can be used for the treatment of breast rock (similar to breast cancer) caused by phlegm-qi stagnation and breast fetish (painful lumps in the breast, closely related to menstrual cycle and emotional changes, equivalent to breast hyperplasia), which can be seen as lumps at the mammary glands, which can be pushed and moved, with no change in color, and which are swollen and hard and painful. Xiao Jin Wan is better for breast nodules caused by phlegm-qi stagnation, but the specific situation is subject to the clinician. The clinical use of both Easy Pill and Xiao Jin Wan should be under the guidance of a doctor’s diagnosis.
