Cupping for Acupuncture .No flames needed.
Similar to those used by Sonny Bill Williams, except his are glass and need flames to create the vacuum.
I was doing this for a while. And no fires are needed. I will definitely be going back to this. If you do this cupping. you will be a rare person with great insight as to the many pathways towards maintaining health.
There might be one set left for personal visitors oh if we can find it.
