Rutin is a bioflavonoid that you can purchase over-the-counter, also known as vitamin P. Rutin is available as an herbal supplement or as a topical cream or ointment, and is not regulated by the U.S. Food and Drug Administration. Rutin is a natural compound in some of the fruits and vegetables that you consume, especially if you eat buckwheat, which is the richest source of rutin. It's best to talk to a doctor before taking rutin for any condition that you may have.
Definition
Rutin is an herbal supplement that is in the classification of bioflavonoids. You can find bioflavonoids in the rind of green citrus fruit, rose hips, black currents, black tea, buckwheat, cherries, prunes and apricots, according to the Vitamins-Supplements.org website. When rutin is digested in your body, it is metabolized and most of it is converted to quercetin.
Uses
As a bioflavonoid, rutin is used in alternative medicine to enhance the action of vitamin C. Additional uses for rutin include supporting blood circulation and as an anti-inflammatory and antiallergenic, according to Drugs.com. Dr. Andrew Weil, a world-renowned integrative medicine pioneer and leader, notes that bioflavonoids such as rutin help to reduce blood pressure, cholesterol and may help to maintain the strength and flexibility of your capillaries, which may help with bruising, hemorrhoids and varicose veins.
Side Effects
Rutin is generally safe to consume, but consulting with a health-care professional is advisable before you start taking the supplement. Rutin may cause side-effects such as allergic reactions, which include difficulty breathing, chest pain and skin inflammation or itching. Additional side effects include dizziness, abdominal pain, headache, muscle stiffness, dry mouth, vomiting, diarrhea, constipation, light-headedness, heartburn and tachycardia--a feeling that your heart is pounding and racing, according to Physicians' Desktop Reference.
Considerations
If you have a medical condition, are pregnant or are planning on conceiving, consult with a health-care practitioner prior to starting treatment with rutin. It is unknown if rutin will harm a fetus or pass through breast milk during breastfeeding. Drugs.com recommends consulting with a health-care professional to discuss potential risks of taking rutin.
Warning
Rutin is not a substitute for medical treatment; consult with your health-care provider to discuss any potential risks. In addition, seek emergency medical attention if you are experiencing an allergic reaction, including hives, difficulty breathing or swelling of the face, tongue, lips, throat or tongue.
