Chromotherapy is a method of treatment of diseases by colour. It is best used as a supportive therapy along with other natural methods of preserving health such as correct diet, adequate rest and relaxation, exercise, yogic asanas and so on.

According to practitioners of chromotherapy, the cause of any disease can be traced to the lack of a particular colour in the human system. Colour therapy is a technique of restoring imbalance by means of applying coloured light to the body. It was a popular method of cure even in ancient times. Some 2,500 years ago, Pythagoras applied colour light therapeutically and 'colour halls' were used for healing in ancient Egypt, China and India.

The pioneer of modern colour therapy was Niels Finsen of Denmark. Following the discovery, in 1877, of the bactericidal action of solar ultra-violet energy,Finsen studied the possibility of assisting the healing of wounds with visible light. He subse- quently used red light to inhibit the formation of smallpox scars and, in 1896, founded a Light Institute ( now the Finsen Institute of Copenhagen) for the phototreatment of tuberculosis. In 1932, Gerrard and Hessay, two Californian psychologists, scientifically established that blue light had a calming effect and red a stimulating power on human beings.

Blue and red colours are considered at the two extremes with yellow representing the midpoint. These are also the three principal colours in a rainbow. A patient is first subjected to an examination to ascertain which colour he lacks. The deficiency is determined by observing the colour of the eyeballs, nails, urine and excrement. In cases of the lack of red the eyes and nails will be bluish, and the urine and excrement white or bluish. If there is a deficiency of the blue colour, the eyes and nails will be reddish and urine and excrement yellowish or red.

Every substance on earth contains colour. Even the rays cast on earth by celestial bodies contain colour in the form of white light. The rays of the sun contain seven different colours - violet, indigo, blue, green, yellow, orange and red. These are natural colours which are highly beneficial to the maintenance of health and for healing diseases.

According to Dr. Babbit, a well-known authority on chromotherapy, "sunlight is the principal curative agent in nature's laboratory and where light cannot enter, disease does. Chlorosis, anaemia, leukaemia, emaciation, muscular debility, degeneration of heart and liver, dropsical effusion, softening of bones,nervous excitability, physical deformity, stunted growth and consumption are the result of excluding oneself from the beneficial effects of sunlight. "

Sunlight plays an important role in the recovery from chronic diseases. Judicious use of sunlight can be part of the curing process in almost every affliction. The rays of the sun improve digestion and nutrition, quicken blood and lymph circulation and increase the elimination of impurities through the skin.
