Iaso tea

Hi, has anyone tired this tea or heard any ones results?

I personally think that this a typical weight loss scam.  I have a still morbidly obese friend who swears by it -- yet, well, she's still SMO.  

She gave me some, I drank it -- it tastes okay -- but other than slightly helping with my constipation issues, I saw no difference.  JMHO -- I personally think following plan with our excellent tool is a lifestyle and sustainable change far more powerful than some gimmicky tea.
