Enhance the deformability of red cells and improve the aggregation of red cells and blood platelet when light quantum penetrated into blood, thus separate the gathered red cells, decrease the blood viscosity, enhance the oxygen carrying capacity and accelerate the whole body blood circulation. Chest distress, hard breath, headache and dizzy giddy disappear, sleeping obviously improved, tinnitus and lacking in strength relieved after about 15 days irradiation. The laser bio-electromagnetic effectiveness?prevents the blood from gathering and decrease the blood fat. Light quantum could supply the bio-energy, peel off the fat layer which surrounded with the surface of red cells, to restore the negative charge, enhance the repulsive force between red cells, (hen avoid gathering, meanwhile activate much organized enzyme in blood, like SOO. melt the redundant fat in blood, accelerate the free radical cleaning, decrease and erase the fat, cholesterol in vessel, finally restore the smooth of vessel, and avoid the risk of atherosclerosis. The level of serum cholesterol, triglyceride and serum low density lipoprotein decreased obviously after 20-30 days irradiation, then dizzy giddy, headache disappear, good sleeping restore, chest pain, palpitation, limbs numbness and arrhythmia relieved observably. Triglyceride, low density lipoprotein and serum total cholesterol keep in line with the physiological indicators about 90 days irradiation. The laser bio-pressure effectiveness- accelerating circulation via nerve stimulating, and dissolves thrombus. Direct light quantum stimulating effectiveness occurs when irradiate the abundant sympathetic and plexus parasympathetic concentrated on the nasal cavity, reflectively enhance the circulation of blood in the cranial cavity and whole body, then accelerate the blood flowing, avoid thrombosis, improve the blood supply to heart and brain.Purifying blood ,reducing blood preesure ,reducing blood viscosity ,treating rhinitis.Best Sellers Rank: See Top 100 in Health & Household. : B073ZBN3DF.
