CHLOASMA is a discolouration of the skin
characterised by the formation of round or oval patches, nickel-sized
or larger, having a yellowish or brownish colour.
The disease is of ineternal origin and hence external applications
will not be of much use.
It occurs more in women than in men and is situated chiefly
about the face and neck.
It usually appears in the form of crescent-shaped patches
on the forehead and temples, also about the mouth
In women, it is frequently found associated with and dependant
upon some physiological or pathological changes in the uterus.
In men, it sometimes occurs in connection with tuberculosis
and prolonged malaria.
Local applications are of temporary benefit. Some useful internal
medicines are --Argentumnit, Lycopodium, Caulophylum, Antimcrud
and Laurocerasus petroleum.
