Sifu Tang is rarely used alone, mainly as a blood tonic. How long it takes to take Sifu Tang to be effective is related to the patient’s constitution, condition, reaction to the drug and other factors, and needs to be analyzed on a case-by-case basis. If the patient has a good constitution in the past, the cycle of taking Siwu Tang may be around 3 months, and one month needs to insist on drinking it for 7-10 days, trying to drink it 2-3 times a day. However, if the patient has a poorer constitution, it may take 5-6 months or longer to achieve the desired toning effect. Patients are advised to visit the Chinese medicine department and be treated by a professional doctor after a face-to-face examination, and to judge the specific way of medication and the time to take it, under the guidance of the doctor’s standardized medication treatment. Patients need to note that although Siwu Tang is good, but do not overdose, need to follow the doctor’s instructions, to avoid the opposite of what is necessary, thus causing a burden to the body. If discomfort occurs in the course of using the medicine, you need to immediately stop the medicine and consult your doctor for appropriate treatment and therapy.
