Gua sha treatment is a traditional East Asian healing technique that’s similar to cupping and acupressure. A practitioner lubricates your back then pressure-strokes it with a small, rounded tool. Gua sha is sometimes referred to as spooning because it can be done with the edge of a metal spoon You can also use a metal bottle cap, a coin or a tool made from horn or jade. The most striking aspect of this technique is the bruise-like streaking it leaves.
