Gua Sha on the back can help with sleep.
Consider using it for thyroid and breast nodules.
Apply oil locally, use a suction cup, and after suctioning, push and pull as needed.
Stop when sha appears.
This can be done daily, or after the sha fades.
Suction cups
Not expensive, very effective.
Fixed cupping is also effective.
Can treat acne, eczema, and itchy rashes.
