The ointment was advertised as being effective against a wide range of conditions, including cuts, bruises, sprains, ulcers, bleeding piles and even colds and toothache. It could also be used as an embrocation by rubbing it into the muscles of the back, legs or feet.
The source of the name is uncertain, but a link to South Africa has been suggested. The brand name was at one time used to refer to ambulance-men and first aiders at rugby league matches in Australia and New Zealand.
