In the theory of traditional Chinese medicine, fried salt or rice hot compress, also known as "ironing", can warm the skin, dispel wind and cold, promote qi and blood circulation, remove blood stasis and relieve pain. The above effects can be achieved by smearing fried salt or rice on acupuncture points and muscles of human body, and the salt or rice is cheap and easy to obtain.

Salt or rice compress can relax muscles and accelerate local blood circulation. Hot salt or injection has strong permeability, which can not only make hot air penetrate into human body, but also absorb iron, moisture and cold, diminish inflammation and dispel cold, and change machine pain.

I hope it works for you.
