I can't give exact medical advice, but here are some general information: In Chinese medicine, Radix Glycyrrhizae Preparata and Radix Trichosanthis are considered to be relatively safe drugs, which can usually be used during or before menstruation. Radix Glycyrrhizae Preparata has the functions of harmonizing gastrointestinal tract, soothing liver, regulating qi, invigorating spleen and benefiting qi, and Trichosanthes Radix has the functions of clearing away heat and toxic materials, resolving phlegm, relieving cough, relieving swelling and resolving hard mass. However, the specific dosage, type and time should be determined according to the individual's physical condition and illness, and it is best to use it under the guidance of a doctor or Chinese medicine. Especially during menstruation, it is recommended to avoid using herbs that cause uterine contraction, so as not to affect the normal discharge of menstruation. In addition, some Chinese medicines may interact with other medicines or have dangerous side effects in some cases. Therefore, it is best to consult a doctor or Chinese pharmacist before using Chinese medicine.
