Didn't you find a strange phenomenon? There are countless "experts" and specialized clinics for diseases that are difficult to cure under the current medical conditions, as well as endless specific drugs and "ancestral" secret recipes, and there are often "authoritative" reports to overcome such a stubborn disease.
Drugs that are endlessly advertised on radio and television cannot be said to be ineffective. Since it is a drug, it certainly has some effect on some people, and it may even have a good effect, but there is absolutely no one-size-fits-all product that has a good effect on everyone.
We should all understand that the main goal of these businesses in manufacturing these drugs (including the so-called "drugs") is not to make money by "saving lives", but to make big money by selling "drugs".
