Narrated Abu Kabsha al-Anmari told that God’s messenger used to have himself cupped on the top of his head and between his shoulders and that he used to say:
“If anyone pours out any of this blood he will not suffer if he applies no medical treatment for anything.”
Salma, the Prophet’s woman-servant, told that no one complained to God’s messenger of a headache without his telling him to get cupped, or of a pain in his legs without his telling him to dye them with henna.
