Take it twice a day on an empty stomach in the morning, before going to bed or before meals at night. Pour out 20-30ML of enzyme stock solution each time, add 3-8 times of warm water (which must be below 40℃), dilute it and take it after stirring. Each bottle can be taken for two weeks as a course of treatment. According to different personal constitutions, 1~2 course can experience obvious effects. I suggest you take it for more than 2 courses to stabilize the curative effect and stay away from all kinds of sub-health and chronic diseases completely.
