Which Qur'anic surah is used to treat headaches and stop blood bleeding?

It was mentioned regarding the treatment of headaches that when revelation descended upon the Prophet, peace and blessings be upon him, he would develop a headache, and he would wrap his head with henna. It was also narrated that during his final illness, he said, "Oh, my head!" and he would bind his head. Furthermore, whenever someone complained to him about a headache, he would tell him, "Perform cupping."

As for the treatment of bleeding and wounds, it was narrated that when the Prophet, peace and blessings be upon him, was wounded in the face on the Day of Uhud, Fatimah took a piece of mat, burned it, and placed it on the wound, and the bleeding stopped. He also used to say to the sick person: "In the name of Allah, the soil of our land, with the saliva of some of us, our sick will be cured, by the permission of our Lord."

No specific verses were revealed for the treatment of these ailments, but the Quran in general is a cure, as Allah Almighty says: (And We send down from the Qur'an that which is a healing and a mercy to those who believe), and the Prophet, peace and blessings be upon him, said: "The best medicine is the Quran."
