Why is the Bioquant applied using laser light through the nasal cavity?

It once happened to me that a gentleman called me and heard that we were supposed to put light in the nose and what nonsense it was. I tried to explain something to him and finally he understood. So I would like to explain why the nasal cavity.

Why the nose?

The nasal mucosa is richly congested and has a large network of capillaries. After all, when we injure our nose and start bleeding, it takes a while for the bleeding to stop.

The skin contains melanin and so light would lose its properties more significantly when passing through the skin than when applied in the nasal cavity.

Rapid absorption of photons into the blood

The response to application in the nasal cavity is very rapid and after only four minutes, changes in viscosity and rheology can be observed on a microscope during the analysis of live blood. However, it depends on the initial state of the user. Relatively healthy people react very quickly and people with more serious changes in the body react more slowly and need more applications. With repeated applications, the effects in the body remain longer and develop from local to systemic. And gradually the symptoms of the disease improve.

Nerve endings

Another advantage of the nasal cavity is the number of nerve endings belonging to the six meridians, and red light thus stimulates the acupuncture points belonging to these meridians. During the application, the olfactory epithelium is also irradiated and we have a case of the return of the sense of smell of one lady who lost her sense of smell for several years and the doctors could not help her for years.

Since the red light that symbolizes its red color energizes, the entire irradiated area, including the ocular background, is of great benefit from the application. This cannot be achieved by application to other parts of the body. There is a lot of literature on the topic called "photobiomodulation" and all its effects are described in detail, including red light.

I quote one professor's hypothesis:

ORIGINAL: There are six meridians inside / around nose, stomach meridian of foot yang-ming, du meridian, yin-jiao meridian, yang-jiaomeridian, large intestine meridian of hand yang-jiao, and small intestine meridian of hand tai-yang. These six meridians can be irradiated by intranasal LIL through intranasal multiple reflex. They are supposed to mediate some of the therapeutic effects of ILILT. This is called the meridian mediated ILILT hypothesis (MIH). (Liu et all)


The nasal cavity is an ideal place to apply a laser to correct blood rheology. There are other methods, such as intravenous administration, which administers the laser directly into a vein, but these applications are invasive and limited in number. Another application is a transcutaneous application, the effect of which is lost by passing through the skin. Therefore, the nasal cavity is considered to be the most effective method, which is non-invasive, which irradiates not only the blood in this area, but also nerve endings and meridians.
