Strawberry leaves (Fragaria × ananassa, Fragaria vesca) are primarily used to relieve gastrointestinal distress and joint pain. Strawberry leaf tea is most commonly used to improve digestion and balance the acids throughout your digestive tract to relieve symptoms of gastrointestinal distress. Strawberry leaves contain tannins, bio-molecules that bind to proteins, amino acids, alkaloids and other compounds with a low pH that may be placing excess stress on your digestive system. Strawberry leaves can help alleviate an upset stomach, and reduce symptoms of nausea, bloating, stomach cramps and diarrhea. Also can help alleviate pain and swelling associated with conditions such as arthritis and rheumatism. Strawberry leaves contain trace minerals and vitamins, such as iron, calcium and Vitamin C that are important for the health and maintenance of many different bodily functions.  NOTE: If you are allergic to strawberries, you may also experience a potentially severe allergic reaction to strawberry leaves, or the tannins and other compounds extracted from them.
