The duration of Chinese herbal medicine for body conditioning has a lot to do with the efficacy of the herbal medicine, the way it is used, the dosage as well as the patient’s condition and constitution, and needs to be analyzed on a case-by-case basis. Most of all, it depends on the different causes of the disease. For example, it takes 3-6 months to improve the immune function of the body. Chinese herbal medicine has a mild preventive and curative effect on the body and produces relatively few side effects. Each person’s constitution is different, the dosage form of herbal medicine is different, the absorption ability of herbal medicine is different, and the curative effect produced is also different, so the time for conditioning the body is also uncertain. Generally speaking, if the patient’s condition is mild, he may need to take three courses of treatment, usually every 7 days as a course of treatment, with an interval of 2-3 days in between. If the patient’s condition improves after three courses of treatment, the drug can be discontinued. If the patient’s condition still does not improve, it is recommended to consult the Chinese medicine department or related departments and ask for the doctor’s opinion to determine whether the formula needs to be adjusted. It is recommended to maintain a reasonable diet, eat more vegetables and fruits, and engage in appropriate activities to improve one’s immunity and make the body healthier and more energetic while regulating the body with herbs.
