Cupping with a funnel is a technique where ozone is introduced to the body surface on a specific restricted area at a low flow rate. The area to be treated should be wet and then the glass funnel is held firmly over the specific area. The flow rate should be low at 1/32 - 1/16 LPM. Funneling can have good results when applied daily for three weeks and up to three months.
Availble sizes are 2 inches, 4 inches, and 6 inches.
