Karsai Nei Tsang is an ancient form of genital therapeutic healing and detox massage exercised in Thailand both for men and women.
Karsai recently became better known due to Mantak Chia, the founder of the Tao Garden, who integrated the practice in his Healing Tao System. The modality is closely related to Chi Nei Tsang, which is a therapeutic healing massage for the abdominal area and internal organs.


The purpose of Karsai is to heal and stimulate the genital system, by removing blockages in the genital area. Karsai Nei Tsang focuses on issues associated with the sexual organs, frequent and difficult urination, impotency, orgasms, premature ejaculation, painful menstruation, or painful scar tissue after giving birth, low sexual libido and painful intercourse.
Besides the above, Karsai Genital Massage seems to be effective also in reducing or eliminating lower back pain, helps improving body alignment and increases general vitality.
Below, we display the Thai Massage schools and teachers in Thailand that offer Karsai Nei Tsang courses and workshops.
