The role of the foot patch is mainly two aspects: first, paste the foot Chungquan point, because Chungquan point is the original point of the foot Shao Yin kidney meridian, paste this point, can effectively play the role of nourishing Yin to reduce fire. And the foot patch can be added to the drug ingredients to nourish Yin and reduce fire, such as Huang Lian, Scutellaria baicalensis, ground bark, cypress and peony, raw earth, angelica and other drugs. It can effectively increase the effect of nourishing Yin and lowering fire, effectively treating the human body after the Yin deficiency fire caused by dry eyes, red eyes, astringent eyes and weakness, sweating and other symptoms.
