Narrated Abu al-Darda: The Prophet ﷺ said: Allah has sent down both the disease and the cure, and He has appointed a cure for every disease, so treat yourselves medically, but use nothing unlawful.

Narrated Usamah ibn Sharik: I came to the Prophet ﷺ and his Companions were sitting as if they had birds on their heads. I saluted and sat down. The desert Arabs then came from here and there. They asked: Messenger of Allah, should we make use of medical treatment? He replied: Make use of medical treatment, for Allah has not made a disease without appointing a remedy for it, with the exception of one disease, namely old age.

Narrated Tariq ibn Suwayd or Suwayd ibn Tariq: Wail said: Tariq ibn Suwayd or Suwayd ibn Tariq asked the Prophet ﷺ about wine, but he forbade it. He again asked him, but he forbade him. He said to him: Prophet of Allah, it is a medicine. The Prophet ﷺ said: No it is a disease.
