Water is LIFE. You are Water. Terahertz frequency lies in the energy range of hydrogen bonds which means that even simple molecules absorb terahertz well, ESPECIALLY WATER.
Water content varies widely depending on tissue type and physiological state. Adipose tissue ranges from 18 to 32% water in, muscle is relatively stable at about 75% water, the average for brain tissue is about 78% and for bone, it is about 10%.
The reason the iTeraCare Quantum Terahertz Device works so well is that the terahertz frequency is mostly absorbed by water.
By weight, the average human adult male is approximately 60-70% water.
In the case of large biomolecules such as proteins, DNA, RNA, lipids, and even polysaccharides, with their multiple and unique vibrational modes and complex intramolecular interactions (e.g. protein folding and DNA double-strands) and associated counter-ion aura, terahertz is expected to be a good functional affecter. Proof of this can be found in the ever-growing body of studies showing the terahertz spectral signatures of different biomolecules such as biotin, DNA, albumin, collagen, carbamazepine, glucose, lactose anhydrate, indomethacin, lactose, and many others.
