Traditional Chinese Medicine classifies dis-ease, and the herbs and foods that heal them, in very different manners. With this, practitioners can open or close channels within the body, move qi around the body, dispel toxin, increase fluids, etc. TCM labels each herb or food with a characteristic, for example, dispels heat, increases qi, increases yin (upward flow) increases yang (downward flow) of energy in the body. It's very real, and very effective. Google your favorite fruit or vegetable and TCM characteristics, you will learn a lot. Meridians and acupuncture are very real. They were known about by ice age humanoids (see Otzi) many eons ago. There are more acupuncture systems than just Chinese too, there are Korean and Japanese variants as well. Same goes for Ayurveda, though that gets more into the astrological and medical component of the soul which inhabits the body (vata, pitta, kapha) Do a little digging on it. It is imperative that humans unlearn 99% of what Western Medicine taught us.
