here's a common and well-known remedy that some Asians may use:

Koo' (rub) kchall (wind) is used to treat a variety of ailments, including fever, upper respiratory infection, nausea, weak heart, and malaise. A coin is dipped in a mentholated medicine and rubbed in one direction (away from the center of the body) in a symmetric pattern on the patient's chest, back, and/or extremities. This is referred to in western literature as "coining" or "dermabrasion."

this is said to be a Cambodian remedy, but i'm mixed and this is very common among family and relatives. very effective. if the skin don't appear red, then that means you are not sick enough or it's been done wrong.
