It is not possible to generalize how long it takes to stop taking herbal medicine. The length of treatment varies for different herbs for different diseases. A small course of treatment takes about 3-5 days, and a long course of treatment takes about 2-3 months. The length of treatment varies for different diseases with herbal medicine. For example, for some acute diseases, the course is short and can be cured in 3-5 days by taking Chinese medicine treatment. Some skin diseases and chronic diseases have a longer duration and require several months of treatment before they become effective. During their treatment, they should visit the TCM department regularly, usually once every 1-2 months, to review the hospital and adjust the medication according to the changes in their condition. In addition, drugs such as He Shou Wu, Mu Tong and Huo Ma Ren have large toxic side effects and need to be stopped for 2-7 days after taking them for about 2 weeks to avoid excessive accumulation of drugs in the liver and kidneys, causing drug toxicity. Patients should pay attention to rest, light diet and drink more water while taking Chinese medicine in order to accelerate the metabolism of the drugs and reduce toxic side effects.
