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.
Infrared (IR) radiation is a type of electromagnetic radiation (a wave with electricity) . The wave is longer than light which humans can see and shorter than microwaves. The word infrared means below red. It comes from the Latin word infra (meaning below) and the English word red. (Infrared light has a frequency below the frequency of red light.) Red light has the longest wavelength that human eyes can see. Infrared waves cannot be seen by the eye. The infrared wave is between 800 nm and 1 mm. People sense infrared as heat.
