Herbal teas

The benefit:risk ratio


There is a long history of use of herbal teas. Recently, evidence has been produced outlining a number of possible medicinal effects of these teas including antioxidant activity, antimutagenic activity, immune response activity, anti-allergic activity, anti-diabetic properties, in addition to their beneficial mineral content. A wide range of adverse effects have been reported, in addition to the possible presence of pesticides, toxic trace elements, and pathogens. Interactions with conventional medicines are an increasing risk.
