After taking herbal medicine for a period of time, your body pattern will undergo changes and show improvements gradually.  Thus, it is important that you return for follow-ups so that the doctor can adjust the prescription according to your most recent condition and provide you with a new prescription after diagnosis.  As a reminder, do not take the same prescription for a long period of time without doctor’s approval as it may cause unhealthy or negative treatment effects.
