Food sources that contain rutin, also known as vitamin P-1, bioflavonoid and rutoside, include buckwheat, noni fruit, black tea, citrus fruit rinds and mulberry. Non-edible plants containing rutin include forsythia, hydrangea and tobacco. You can buy supplements containing rutin over the counter at your local health food store. As with any medication or supplement, adverse reactions may occur. Consult with your health care professional before taking rutin, especially if you are pregnant, breast feeding or have high blood pressure.
Supplement
Rutin is taken as an oral dietary supplement. It’s employed to treat hemorrhoids, poor circulation, Meniere’s disease, varicose veins and skin bruising, according to information provided by PDR Health. Meniere’s disease is an abnormality of the inner ear. Rutin accompanies ascorbic acid as an ingredient in vitamin C supplements because it intensifies its activity.
Dosage
Your health provider can supply you with information on how much rutin you should take. PDR Health explains that the appropriate dosage depends on your condition and the strength of the supplement or medication. In situations where you have no access to a health care provider, PDR Health cautions against exceeding the dose and frequency listed on the bottle of rutin.
Vessel Health
Rutin may positively affect blood vessel health. Administered over a five-year period in a study conducted by the Department of Biomedical Sciences at Chieti-Pescara University in Italy, rutin proved to be an effective treatment for venous edema and hypertension. This controlled trial, published in the February-March issue of "Angiology," reports trial participants did not experience adverse effects from the rutin treatment.
Arthritis
Rutin shows promise as an anti-inflammatory. In animal studies, rutin “inhibited clinical signs of chronic arthritis,” according to a study conducted by the School of Pharmacy at Bordeaux 2 University. It reports in a 2008 issue of the journal “Arthritis Research and Therapy" that rutin could have “clinical value in reducing inflammatory manifestations in human arthritis and other inflammatory diseases.”
Side Effects
Taking rutin may cause side effects or an allergic reaction in some people. If you experience respiratory problems, chest pain or hives, PDR Health warns you may be experiencing an allergic reaction. Other reported side effects include, but are not limited to, dizziness, tachycardia, hair loss, vomiting, constipation and abdominal pain along with leg or finger swelling. If you experience any of these symptoms or other manifestations, discontinue use and contact a health professional immediately. Do not induce vomiting unless instructed to do so.
