“Detox” is applied to so many products on the herbal market these days, that its almost impossible to know what the word means anymore. Are we talking about weight loss or expelling toxins from drugs, pollutants, or unhealthy eating? Is the goal to detox the digestive system, liver, kidneys, or lungs? I think we all deserve a little clarity here. In Traditional Chinese Medicine guava leaf, or fan shi liu ye, is said to strengthen the spleen, promote digestion, and astringe the intestines. What this means is that the leaves support healthy digestion, curb the appetite, and clean the intenstines of whatever they’ve been holding onto. As such, the tea may be helpful for weight loss as well as general gastrointestinal detox or cleanse.
