Jesus’s miracle of Healing the man blind from birth as depicted in El Greco‘s Healing of the Man Born Blind, 1567

Fasting spittle – saliva produced first thing in the morning, before breakfast – was a treatment used in folk medicine in the ancient Mediterranean. Spittle was thought to cure many diseases. Spittle cures were usually considered to be more effective if fasting spittle was used.[1]

An early reference to the alleged medicinal benefits comes from the Roman author Varro, who mentions it as a cure for epilepsy and snake bites among other ailments.[2]

Roman natural philosopher Pliny commented in his Natural History that fasting spittle was efficacious in the treatment of ophthalmia, and that the fasting spittle of a woman was particularly beneficial for treating bloodshot eyes.[3]

The New Testament contains multiple instances of Jesus using spit as a cure. The Gospel of Mark records Jesus spitting directly into the eyes of a blind man, and the Gospel of John records Jesus using a mixture of spit and mud to make a poultice for healing blindness.[4][5]

And they bring unto him [Jesus] one that was deaf, and had an impediment in his speech … And he took him aside from the multitude, and put his fingers into his ears, and he spit, and touched his tongue; and saith unto him, Ephphatha, that is, Be opened. Mark 7:32–5


When he had thus spoken, he spat on the ground, and made clay of the spittle, and he anointed the eyes of the blind man with the clay. John 9:6

Suetonius, Tacitus and Cassius Dio mention Roman Emperor Vespasian treating blindness in a similar fashion.[2] Tacitus mentions that Vespasian consulted with physicians before healing the blind man with his spit. Tacitus also gives a natural, medical explanation for the healing, unlike Suetonius and Cassius Dio who ascribe a more supernatural aura to the restoration of the blind man’s sight.[6]

The Talmud also references the alleged medicinal benefits of saliva, particularly that of a first-born son.[7]

A certain person once came before R. Hanina and said to him, ‘I am sure that this man is firstborn’. R. Hanina said to him, ‘How do you know?’ — The person replied to him: ‘Because when people came to his father, he used to say to them: “Go to my son Shikhath, who is firstborn and his saliva heals’. Might he not have been the firstborn of his mother only [but not of his father]? There is a tradition that the saliva of the firstborn of a father heals, but that of the firstborn of a mother does not heal.

— Bava Basra 12:6b of the Talmud
