Hematohidrosis is a rare condition in which a human being sweats blood.
Leonardo Da Vinci described a soldier who sweated blood before battle. Jesus Christ experienced hematohidrosis while praying in the garden of Gethsemane before his crucification as mentioned in the Defenders Bible by Physician Luke as “and being in anguish he prayed more earnestly and his sweat was like drops of blood falling to the ground.”
