”People were often blind at an early age,” says Totelin, whose research has discovered couching to have been a long-standing practice. There are several ways that a practitioner can create the suction in the cups. The cups could be placed over acupuncture needles for these treatments.  According to Ann Michelle Casco, L.Ac., a traditional Chinese medicine practitioner and acupuncturist at the integrative medicine canter Pacific Pearl La Jolla, the classic cupping technique is called Ca Juan Fi, which is fire or dry cupping. There are also specially designed cups fitted with air lock valves that allow practitioners to remove the air with a hand-held pump. However, the American Cancer Society notes that “available scientific evidence does not support claims that cupping has any health benefits” and also that the treatment carries a small risk of burns. 2 Cupping is generally safe when done by trained health professionals on people who are otherwise healthy. 7 It is not recommended in people with health problems due to side effects. 7 Cupping is not recommended as a replacement for typical treatment. 7 Cupping may result in bruising, burns, pain, or skin infection. 7 Research suggests that cupping is harmful, especially in people who are thin or obese. citation needed According to Jack Faso 1997, cupping results in capillary expansion, excessive fluid accumulation in tissues, and the rupture of blood vessels. 8 Fire Cupping can sometimes result in minor to severe burns, and can lead to hospitalization and may even require skin grafting to repair the injury. Cupping is a therapy used in traditional Chinese medicine acupuncture ACM to remove stagnation and stimulate the flow of qi chi. According to ACM, this would be a favourable outcome, suggesting the treatment has successfully removed toxins and stagnation. The cotton is then clamped by a pair of forceps and lit via match or lighter. Usually sciatica acupuncture treatments are not painful. Fire heats the inside of the cup and a small amount of suction is created by the air cooling down again and contracting. Some clinical research from China suggests this innovation in cupping technology is more comfortable for patients. Like acupuncture, cupping follows the lines of the meridians. The introduction of glass cups helped greatly, since the pottery cups broke very easily and the bamboo cups would deteriorate with repeated heating. 

Then ignites the soaked cotton ball and places it in the cup. - Includes 6 different pumping modes. Originally, animal horn was the original cup. There is no scientific evidence that cupping can cure cancer or any other disease.” Movement of the cups is a gentler technique than guasha, as a lubricant allows the cup to slide without causing as much of the subcutaneous bruising that is an objective of guasha.
