Thesw white spots results from a derangement of your normal defense mechanisms against infection. Actually body starts producing antibodies against pigment producing cells of its own skin.
Generaly these white patches called Vitiligo.
Vitiligo is anomaly of internal immune system of human beings, and currently there are no precise ways to treat this process.
Although the complete annihilation of the vitiligo from your body is a complex matter, whereas original color of skin can be brought back.
According to my observation tropical treatment is quite better Cure of vitiligo because there has no side effect as well as negative effects. Other thing is you can apply it for some affected part of your body for testing purposes. And final thing which you need is tropical treatment is quite faster than homeopathy.
