My initial reaction is that the site is full of hype and that $175 for a few herbal tea bags and some internet download documents is awfully high. Money back guarantees are frequently used as a gimmick to get you to buy something. Many people never follow up on the guarantees, which companies are well aware of. Even it the product is worthless (and I am not saying it is), they can well afford to pay the people go through all the steps needed to get a refund (which may cost up to $150 or more for doctor visits and tests). After all, it costs them nothing for ebook type downloads and their costs for their herbs is likely only a few dollars per package.
There are less expensive effective ways to kill H. Pylori and heal stomach ulcers. Some can be found here:
