This product is absolutely horrible and made me feel worse than ever. I normally don't leave negative reviews but I feel like I'd be doing a disservice to people by not leaving this one. There's an insert inside the package that says if you share your opinion your next bag is free... so of course there are tons of glowing reviews to get more free product. But honestly I feel so bad on this I wouldn't request a second bag.
In fact, there is no hard evidence backing the claims made by tea companies that their detox teas actually purify human cells.

I have experienced exactly the same. I bought Yogi Berry DeTox and after just the second day (one cup per day) I could not sleep a minute. It kept me up all night despite that there are no stimulants (e.g. caffeine) in this version of the tea, or at least none is indicated on the label. It seems that some of us just might be sensitive to some of the ingredients.
While the benefits are plentiful, there are some important side-effects that you should keep in mind when drinking these teas. For example, when drinking the Original EveryDay Detox Tea, you should consult your doctor before if you have a history of gallstones or other digestive issues. The EveryDay Detox Tea Lemon can cause allergic reactions in those who are allergic to stinging nettle, dandelion, or burdock root.
