Plant lectins are being studied for over a century. Until a decade ago, most information was obtained from biochemical, molecular, and structural studies of a reasonably high but still limited number of abundant lectins from seeds and vegetative storage organs.
Light therapy boxes should be designed to filter out harmful ultraviolet (UV) light, but some may not filter it all out. UV light can cause skin and eye damage. Look for a light therapy box that emits as little UV light as possible. If you have concerns about light therapy and your skin, talk to your dermatologist.
Effective wavelengths of near infrared light therapy include 700 nm to 1400 nm. The whole range of wavelengths have the same healing and therapeutic effect, the big difference is this: the longer the wavelength, the deeper it penetrates into the body.
