Rutin is a plant pigment (flavonoid) that is found in certain fruits and vegetables. Rutin is used to make medicine. The major sources of rutin for medical use include buckwheat, Japanese pagoda tree, and Eucalyptus. Other sources of rutin include lime tree flowers, elder flowers, hawthorn, rue, St. John’s Wort, Ginkgo, apples, and other fruits and vegetables.
Rutin is most commonly used for swelling in the arms or legs caused by damage to the lymph system (lymphedema) and osteoarthritis. It is also used for autism, or on the skin for sun protection, but there is no good scientific evidence to support these uses.
