Acupuncture through the meridians with time varies from person to person depending on the disease, in a week to several months, if the newly occurred disease with time is generally shorter, if the disease, serious disease, longer time. Acupuncture has the role of dredging meridians and regulating yin and yang, for newly occurring diseases, such as wind-cold cold, wind-cold headache, short-term pillow, shoulder pain, stomach pain, etc., acupuncture treatment is available, the treatment time ranging from 1 to 2 weeks, the specific time varies from person to person. For more serious diseases, such as stroke hemiplegia, long-term chronic stomach pain, intractable headache, etc., the treatment time will be prolonged, ranging from several weeks to several months. In addition, for new diseases where phlegm and dampness (pathological products formed by water-liquid metabolism disorders) are present to block the meridians, the treatment time will also be lengthened due to the heavy and sticky nature of phlegm and dampness. Therefore, the specific time for clearing the meridians with acupuncture depends on the individual’s specific situation, and it is recommended to ask the doctor to select the effective points and have them operated by the doctor.
