Currently there is no authoritative information to clearly state how long after taking Chinese medicine for flatulence will be effective, the specific effect of medication varies from person to person, generally 1 ~ 4 weeks after the effect, can continue to observe the symptoms, should be guided by a physician to use the medication. The time to drink Chinese medicine to regulate the effect is affected by the degree of illness, medication program, physical and other factors, depending on the person, can not be generalized. Generally speaking, under the premise of symptomatic medication, it takes 1-4 weeks, or even longer. The effect of Chinese medicine is slower, not as fast as Western medicine, so patients with flatulence should have enough patience when drinking Chinese medicine. After taking Chinese medicine, we should continue to observe the symptoms of the body, if the symptoms do not improve, the patient should consider stopping or switching to other medications. It is recommended that if a patient needs to drink Chinese medicine to regulate the stomach flatulence, please go to a regular hospital to find a Chinese medicine practitioner to see a doctor, and then prescribe the appropriate Chinese medicine program, do not take Chinese medicine on their own.
