Karsai Nei Tsang is a traditional form of therapeutic genital healing and detox bodywork (also called sexual organs detox therapy) originating and exercised in Thailand and applied for both men and women. Karsai was popularized by Master Mantak Chia, who integrated the practice in his so-called Universal Healing Tao System (UHT).

The healing modality is closely related to Chi Nei Tsang, which is a therapeutic healing work for the abdominal area and internal organs. In fact, Karsai is a specific specialization of Chi Nei Tsang with a more precise focus on the genital organs. “Karsai” means sedimentation in the veins and “Nei Tsang” means working on or transforming the internal organs.

The goal of a Karsai treatment is to cleanse, stimulate and heal the genital and reproductive system by dissolving sediment clogging in the blood vessels (crystal-like sedimentation, toxins, and fat deposits) and releasing tensions and blockages in the genital system.
Blockages can cause organs to malfunction, notably the kidneys, bladder, liver, spleen, pancreas, lung, prostate gland, testicles, ovaries, uterus, and vagina.

The result of cleansing the genital system is an improvement of blood circulation in the body and specifically, blood flow into the genitals and genital area, which benefits functions such as sexual arousal, sexual vitality, and balanced hormonal release, with the latter specifically stimulating the sexual and reproductive capacity and functions.

Karsai Nei Tsang becomes particularly important for men and women over forty (when blockages and sedimentations start to happen more frequently) and for anyone in general who feels sexually blocked or has fertility issues. On the whole, one could say that Karsai Nei Tsang aims at health issues associated with the sexual organs and sexuality, frequent and difficult urination, premature ejaculation, problems having or maintaining an erection, fertility problems, prostate problems, menopause, ovarian cysts, impotency, painful menstruation or painful intercourse, painful scar tissue after giving birth, and low sexual libido.

On an emotional level, it’s clear that better sex life, whether connected to reproduction or perhaps rather to sensuality and eroticism, results in significant stress relief and a better, more happy, and balanced person. In addition, emotional issues due to a sexually repressive childhood or upbringing can be resolved.

As with Chi Nei Tsang, the relaxation or reduction of muscle tension, knots, tangles, and twists in the abdominal and pelvic area can release old trauma (sexual or otherwise) that was bound into cell tissue. Additionally, Karsai Genital massage is said to alleviate lower back pains, and stimulate a better memory, while improving body alignment, strengthening the pelvic floor muscles, overall resulting in a better general vitality and fitness.

When done well, a Karsai session is preceded by a Chi Nei Tsang Abdominal treatment, slowly moving in deeper into the genital area.
The treatment can engage in only external work in the groin, lymphatic glands, or can include internal work also. This counts for both men and women.

For men work is done internally on the prostate and externally on the testicles and scrotum. Work is also done around the anus.
Needless to say, Karsai is not a sensual erotic massage. Moreover, sometimes it can be painful. Note also that the treatment may bring up unpleasant past memories and feelings. Nevertheless, a session may provoke an orgasm or ejaculation, which is fully accepted if it happens during the treatment and is nothing to be ashamed of.

General contraindications for the Karsai treatment are active menstruation, recent surgery, a cardiac pacemaker, pregnancy, alcohol intoxication, fever, or active cancer. As with Chi Nei Tsang, it’s also advised not to eat two to three hours before the session (drinking is no problem).
