Whitfield's ointment

It is named after Arthur Whitfield (1868–1947), a British dermatologist.

[4] Whitfield's ointment is not advised for areas of thinner skin, such as the scrotum or the groin, and in such sites should only be used diluted to half-strength.

[5] A systematic review of the medical literature comparing treatments for ringworm and jock itch was generally critical of the quality of data available.

It concluded that there was "insufficient evidence to determine if Whitfield's ointment, a widely used agent, is effective",[6] implying that the studies were of poor quality and therefore effectiveness could not be determined.

Individual studies support its use as a cost-effective treatment.
