Fasting spittle – saliva produced first thing in the morning, before breakfast – has been used to treat a wide variety of diseases for many hundreds of years. Spittle cures are usually considered to be more effective if fasting spittle is used.[1] Spittle was considered to be particularly effective in the treatment of eye and skin problems, and was considered a standard treatment for warts. The folklorist Steve Roud has suggested that it may have stemmed from the observation that animals often lick their wounds.[2]
An early recorded use of spittle as a cure comes from the Gospel of St Mark, believed to have been written in about 70 AD:
— Mark 7:32–5
Writing at about the same time as Mark, the Roman naturalist and philosopher Pliny claimed in his Natural History that a woman’s fasting spittle is generally considered to be highly efficacious for bloodshot eyes.[1]
