What is the advantage of wet cupping and hijama?

Narrated ibn Abbas, the Messenger of Allah (sallallahu alaihi wasallam) said: I did not pass by an assembly of Angels on the night that I was taken on the night journey (lailatul israa), except that all of them said to me: Oh Muhammad, upon you is cupping" (you should have cupping performed). (Sunan ibn Majah 3477) Narrated Anas bin Malik (radiyallahu anhu) that the Messenger of Allah (sallallahu alaihi wasallam) said: I did not pass by an assembly of Angels on the night that I was taken on the night journey (lailatul israa), except that they said: Oh Muhammad, order your nation with cupping" (to use cupping as a treatment). (Sunan ibn Majah 3479) Narrated Jabir (radiyallahu anhu) that Umm Salamah (wife of the Prophet, sallallahu alaihi wasallam) sought permission from the Messenger of Allah (sallallahu alaihi wasallam) to have cupping performed on her. So the Prophet (sallallahu alaihi wasallam) ordered Abu Taibah to cup her. He said I assumed he was her brother from breastfeeding or a boy in puberty. (Sunan ibn Majah 3480) Narrated Jabir (radiyallahu anhu) when he returned to Muqanna’ he said: I will not leave until you treat yourself with cupping. I heard the Messenger of Allah (sallallahu alaihi wasallam) saying, Indeed, there is a cure (cupping). (Sahih Muslim 2205) Narrated by ibn Abbas (radiyallahu anhu), the Prophet (sallallahu alaihi wasallam) said. There is a cure in three things: in the slash of the cupper, drinking honey, or cauterization with fire, and I forbid my nation from cauterization. (Sahih Al-Bukhari 5681) Many cultures have strongly encouraged this technique for curing ailments. The human body is likely to fall victim to many diseases due to toxins' accumulation and presence in the blood. Many harmful acids, microorganisms, and other substances that can impact the body's normal functioning are sucked out using this technique. In other words, cupping is more like a precautionary measure to purge the body of diseases through blood purification. However, cupping is used successfully not only as a preventive procedure but also as a treatment method. https://philaacupuncture.com/wet-cupping-hijama/
