Some diseases, such as burns, sprains, new injuries and pain are all areas of high temperature and excessive energy emission, which require cooling and calming gem treatment. Other forms of illness, such as old injuries, numbness, paralysis, strokes, some allergies, asthma, thrombosis and blindness are caused by low temperature and low energy emissions. These invariably benefit from stimulating invigorating gem energy.

With Electronic Gem Therapy it is possible to energise one part of the body with, say, diamonds and carnelians, whilst at the same time soothing another part with sapphires and emeralds.
