Sifu Tang is suitable for women with blood deficiency. It is usually recommended to be taken for 7-15 days a month, but it needs to be taken in the context of the patient’s specific situation and cannot be generalized. When taking Sifu Tang, it is necessary to pay attention to the time of taking the medicine, which is recommended to be taken after menstruation for 7-15 consecutive days. Because menstruation itself is the process of draining stagnant blood, if Si Wu Tang is taken at this time, it may cause excessive bleeding or leave the body with a foundation of myoma. In addition, patients taking Siwu Tang need to pay attention to the fact that although Siwu Tang is good, it should not be taken in excess, and should be taken according to the doctor’s instructions to avoid the situation of the opposite of what is necessary, thus causing a burden to their own bodies. During the period of taking Siwu Tang, if there is any discomfort, such as diarrhea, stomach distension, poor appetite, cysts or tumors, it is recommended to visit the Chinese medicine department in time to make appropriate adjustments or treatments under the guidance of professional doctors.
