This classification ensures that the medicine meets mandatory standards for safety, efficacy, and quality control throughout its entire manufacturing and distribution process.
Q: Are there any foods or drinks I should avoid while using Kanpo?

Q: Is it required to tell my healthcare provider I am using Kanpo?

This is especially important before starting any new medications (including non-prescription supplements) to allow for the review of potential interactions.
