Vitiligo also, though not dangerous in itself, is still ugly and is due to a bad habit of body. There are three species. It is called alphos when it is white in colour, generally rather rough, and not continuous, so that it looks as if drops of some sort had been sprinkled about. Sometimes also it spreads still more widely with certain gaps. That called melas differs from it in being of a black colour and like a shadow; otherwise it is similar. Leuce is somewhat like alphos, but is whiter and extends deeper; there are hairs on it, white, and like down. All these spread, but more quickly in some people than in others. The alphos and melas come and go at various seasons; the leuce, once established, is not easily got rid of. The two former are not difficult to treat, the latter is scarcely ever cured, for even if the discoloration is mitigated, the colour of health does not right altogether. But whether any one of these is curable or not is easily learnt by this test. The skin should be cut into or pricked with a needle: if blood escapes, which it usually does in the first two species, there is place for a remedy; if a whitish humour, cure is impossible, and then we should even refrain from treating it. But to the species which admits of treatment we should apply lentil meal, mixed with sulphur and frankincense, pounded up together in vinegar. Another application for the same purpose, ascribed to Irenaeus, is composed of coral, soda, cumin and dried fig-leaves, in equal quantities, pounded up with vinegar added. The vitiligo is smeared with this in the sun, then it is soon washed off, lest it corrode too much. Some find it useful to anoint the species which I have said is called alphos with the following prescription ascribed to Myron: they mix sulphur 1 gram, split alum 0·66 gram, soda 1·33 grams with a cupful of dried myrtle leaves; then at the bath they dust bean-meal over the vitiligo and afterwards apply the above remedy. That which I said was termed melas is treated by pounding up together coral, frankincense, barley and bean-meal; and these are sprinkled on, using no oil in the bath before the patient sweats; then this kind of vitiligo is rubbed off.
