People have taken this and they became even more sick. Further more, JillyJuice claims are not backed with proper evidence. Sources of so-called "evidence" she is attaining is not reliable as it is online.
She also has no medical degree or any certification whatsoever to have the right to make this claims. All claims she makes are based completely on theory and supernatural content. There is also a high sodium content that is risky for many people. Basically, this is promoting a product that isn't even confirmed whether it works or not. I recommend not trying it at all.
