Light and heat are important media of treatment in Naturo pathy. Sunlight gives us both. This is an inexpensive but powerful natural agent and it plays a great part in keeping us in health, as it provides us with two important necessities of life. It is for this reason that the Sun is worshipped as God-the Protector.

Nature has provided a number of expensive methods for the preservation and also for restoration of health when it is disturbed. If it is not convenient or possible for any particular person to use mud-packs or take sun-bath, he can carry with him and take some pills having the effect of the spectral colour of Sun-rays.

Sunlight consists of several visible and invisible rays. It is safe to use visible rays for treating human diseases. The spect rum of visible rays consists of seven colours, namely: Violet. Indigo, Blue, Green, Yellow, Orange and Red. Of these, Blue. Green and Red are primary colours and the rest are mixtures thereof. The main combinations can give us over 200 hues and shades otherwise the seven colours can be multiplied into an unlimited number. These colours can replace hundreds of medicines in use these days.

We lose ourselves in wonder at the majesty of the perfectly ordered colours and must realize that beauty in the world is not by chance Travlling in a plane we get only a glimpse of the cosmic vastness and the role of the Sun in the cosmic whole. The different vegetables, fruits. flowers. nuts, grains. etc,. derive their different colours from their paramount source the Sun, which is the Supreme Power House.

It has been ascertained by the Scientists that every substance has a colour spectrum of its own. This means that every drug also has its own colour spectrum. It is, therefore, logical and has also been proved by experience that spectral colours can be used directly in place of drugs for medical effects. Thuschromotherapy uses spectral colours directly in place of conven tional drugs with the result that there is no drug after-effect. Of the 7 colours mentioned above, blue is cooling and soothing, red is warming and stimulating and green is harmonising in between the two and Nature’s best blood purifier. Just as there are 3 Doshas in Ayurveda, namely: Vat, Pitta and Kaph, there are these 3 primary colours in chromotherapy. So long as the three colours are in a balanced state, a man remains in health but when this balance is upset, a state of disease is noticed. As every medicine has some colour, every organ of the body also has some colour. For treatment in chromotherapy. the colour of the diseased organ and the temperament of the patient are ascertained and the harmonising colours are used which correct the ailments. We have specific medicines which act directly on certain. organs; similarly there are certain colours for which different organs have affinity. Describing the affinity of every colour or every organ for a particular colour becomes a matter of detailed study which is out of the scope of this Chapter. Hence the details about the affinity are not given here..

The main medium for administration of colour effect is water but oil, sugar, candy, fruit juices and sugar milk, etc. can also be similarly charged with the colours and these things can be used for longer periods.

                                                            Method of Preparation of Solar Medicines

The healing effects of the spectral colours can by two ways: obtained

(i) by external application to the body by passing Sunlight through various coloured glass sheets, or cellophane paper, and

(ii) by preparing solar medicines for internal and external use.The latter is done by exposing to sunlight, water, milk, powder.or oil, etc., stored in coloured bottles for a number of days. The medicinal effect of the colours is absorbed the medium stored in the coloured bottles. The colour rays pass easily through water medium, so we get a medicinal charge on the water quickly-say, within eight hours of exposure to sunlight. Oils and solids have, however, to be exposed for a month or so to obtain an effective medicinal colour charge.

We have seen that, in chromotherapy, the power of the Sun is utilised through the colours of Sun-rays. In magnetotherapy, the power of magnets is made use of to cure diseases, magnets are believed to have solar power as they give heat to the body. when applied to it and the magnetic waves spread out like the rays of the Sun. Hence it is evident that both the systems of treatment draw their power from the same source i.e. the Sun and are, therefore, alike to some extent. Moreover, just as water is charged with colours in chromotherapy, water is also charged with magnetism and magnetised water works as a good medicine in the diseases of abdomen, stomach and in urinary troubles including stones in kidneys.
