Favus

Favus, a skin disease produced by the growth of a fungus known as the achorion schbnleinii. The disease usually affects the scalp, and produces yellow, irregular crusts, and leads to the falling off of the hair. It is more frequently met with in children than in adults, and is rare in England, but not uncommon in Scotland. Treatment consists in poulticing and washing the affected parts, and when cleanliness is secured in applying remedies to kill the parasite.
