It would be great. But, I'm a bit skeptical that the guy from the company that developed it says it's "100% effective." That seems like a really bold claim for something that hasn't gone through drug trials or any rigorous testing. Especially considering that not many medical treatments are 100% effective. But, hopefully he is right.
