Apart from being a traditional Chinese therapy, which has been going on for over 2000 years, it is also highly recommended by Prophet Muhammad (PBUH).
There are various incidents and traditions recorded in the books of Hadeeth, which prove the use of cupping in Arabia, by the Prophet (PBUH) and his Companions, and many books have been written regarding its benefits.
“The Prophet (PBUH) was cupped on his head for an ailment while he was in a state of Ihram, at a place called Jamal.” [Sahih Bukhari 76:21]
“If there is any good in your medicines, then it is in a gulp of honey, a cupping operation, or branding (cauterization), but I do not like to be (cauterized) branded.” [Sahih Bukhari 76:22]
“The best medicines you may treat yourselves with are cupping and sea incense.” [Sahih Bukhari 76:18]
“There is healing in cupping.” [Sahih Bukhari 76:19]
The Prophet (PBUH) also said:
“I did not pass by an angel from the angles on the night journey (Israa), except that they all said to me: upon you is cupping O Muhammad!” [Tirmidhi: 3477]
In another narration it’s mentioned: “Order your nation to perform cupping.” [Tirmidhi: 347]
