Patient discussion about efficacy

Q. What do you think about the efficacy of Chinese medicine?

A. Did you know that Traditional Chinese Medicine works around the lungs, kidneys, liver and heart? Besides this, TCM also works around the small and large intestines, stomach, gall bladder and the urinary bladder. Being connected with ‘qi’ energy and blood, the vital substance, circulating through them, TCM uses a holistic approach to harmonizing the functions of these organs. TCM has deployed the theory that all structures in the body should work in tandem with the other and with the environment that surrounds us.
