Where does this knowledge come from?
According to Yunyin Sam, Chairman of the Chinese Medical Treatment Association, the so-called "Life Energy Cure" is adopted from traditional Chi Gong treatment. According to Chi Gong therapy, the Chi radiated by a Chi Gong master is called "external chi" and Chi circulating within the body is called "internal Chi."
When one is sick, the internal (Life energy) Chi is disturbed and this results in an imbalance in bodily mechanisms. In order for the mechanisms to resume their proper function, life energy in the human body must resume its free communication without disruption. New Chi whether it be "internal Chi" self-generated by the patient through Chi Gong exercise or whether it be "external Chi" radiated by a Chi Gong master, needs to be supplied to support or adjust the bodily mechanisms so disease can be cured.
All medical treatments such as acupuncture, electrotherapy, magnetic energy, Reiki and certainly FIR are all based on the same principle.
Chi radiated from a Chi Gong master is actually a form of FIR with electromagnetic wavelengths in the same 8-14 micron range.
Is there any research to back this up?
Research by NASA also indicates that within the rather broad infrared radiation spectrum, those in the 8-14 micron range most effectively penetrate the human body. It then naturally follows that when FIR of this frequency range is used in therapeutic treatment, it will have the greatest beneficial effect on the patient. This is because it is the frequency best able to produce the warmth necessary to expand capillaries and stimulate blood circulation.
Is FIR good for removing toxins from the system?
"One of the reasons FIR has beneficial results in a variety of illnesses is the ability of FIR waves to remove toxins which are often at the core of many health problems. Toxins in our body appear in water as clumps or globules. Blood circulation becomes blocked and cellular energy impaired where these toxins accumulate. However, when the energy from FIR is applied to water molecules containing toxins, the water begins to vibrate, releasing the encapsulated gases and other toxic materials back into the bloodstream where they are removed naturally by the body's normal detoxification process.
One study done by American researchers showed that the sweat released by users of a FIR sauna (80-85% water) was different from the sweat released by users of a conventional sauna (75-95% water) or doing normal exercise. The non-water portion of sweat released in a FIR sauna was cholesterol, fat-soluble toxins, toxic heavy metals, sulphuric acid, sodium, ammonia and uric acid".

Can FIR damage healthy cells whilst it is eliminating unhealthy cells?
No, unhealthy cells have a lower frequency which cannot tolerate the frequency put out by the FIR rays, whereas it just revitalizes normal cells because they are the same hertz, the same frequency, the same oscillation.
