This is skin disease caused by fungi. In Ayurveda, this is called dadru. The infection spreads peripherally and heals centrally with the result that the earlier region becomes a ring with scaly or vesicular border and a central zone of normal or recovered skin.
Ringworm infection can affect both humans and animals. The infection initially presents with red patches on affected areas of the skin later spreads to the body. The infection may affect the skin of the scalp, feet, groin, beard or other areas.
Haridrakhand, mahamarichyai oil, neem, turmeric are the ayurvedic treatment for ring worm.
