It was narrated from ‘Abdullah that the Prophet (Peace be upon him) said: “Allah does not send down any disease, but He also sends down the cure for it.”Sunan Ibn Maajah, Book 31, Hadith 3438
Ultimately, Allah has control over everything. If He withholds a cure from someone, no one can give it to him. If He gives a cure to someone, no one can withhold it from him. Anyone seeking a cure first needs to turn to Allah and ask Him for help. Then they should take whatever means they can to find a cure. With that said, here are some cures and treatments found in the Sunnah of our Messenger Muhammad ﷺ.
And We send down of the Qur’an that which is healing and mercy for the believers, but it does not increase the wrongdoers except in loss.(Qur’an 17:82)

And your Lord inspired to the bee, “Take for yourself among the mountains, houses, and among the trees and [in] that which they construct. Then eat from all the fruits and follow the ways of your Lord laid down [for you].” There emerges from their bellies a drink, varying in colors, in which there is healing for people. Indeed in that is a sign for a people who give thought.Qur’an 16:68-69

A man came to the Prophet ﷺ and said, “My brother has some Abdominal trouble.” The Prophet ﷺ said to him “Let him drink honey.” The man came for the second time and the Prophet ﷺ said to him, ‘Let him drink honey.” He came for the third time and the Prophet ﷺ said, “Let him drink honey.” He returned again and said, “I have done that ‘ The Prophet ﷺ then said, “Allah has said the truth, but your brother’s `Abdomen has told a lie. Let him drink honey.” So he made him drink honey and he was cured.Sahih Bukhari 5684
