The unique benefits of sour cherries (not to be confused with sweet cherries) first came to light in the 1990s, when numerous studies were published concerning the antioxidant content of this fruit. Further research has identified the active antioxidants as eight polypholic compounds, including anthocyanidins and quercetin. As well as potent antioxidants, anthocyanidins have been purported from studies to also possess anti-inflammatory properties. Furthermore it has been shown from studies on sour cherries that particular compounds found in these fruits may inhibit the inflammatory pathways associated with uric acid production. Toetal is a sour cherry concentrate that has been carefully processed to ensure the powerful antioxidant properties are retained. Sour cherries are thankfully not however a reflection of the taste of Toetal which is naturally sweetened with red grape and apple.
