A List of Tea and Herbal Infusion Health Claims We’ve Come Across

Health claims for teas and herbal infusions are one of the easiest things to find online. What’s tricky is finding what these are based on. For many we found no supporting studies at all. In fact, most of the claims have no merit and are highly disputed by medical authorities. We present them here more for pointing out how many things are attributed to these beverages, but we leave it to you to consult with your doctor about their veracity.

True or False?

As stated earlier, some of these, such as the presence of antioxidants, are fairly well-supported by various studies. The cancer claims are another matter, with some reputable sources saying true and others saying false. As for weight loss, that is almost always very much up to the individual and has to be considered along with a variety of other factors such as genetic make-up, lifestyle changes as a result of switching to drinking tea (you may, for example, tend to eat at fast food places less often, not that eating at these places will necessarily make you fat), activity level changes when you switch to drinking tea, and so on.

So, here’s that disclaimer that we always like to include when discussing such matters: consult your doctor.

We do know that the lack of sugar is helpful for diabetes, and the energy needed for a good gongfu session is helpful in burning up excess fat. Other than that, who knows.
