Quercitin is a bioflavonoid supplement that helps the body in numerous ways

There are plant substances, closely linked to vitamin C, that give many fruits and vegetables their hues of red, blue and yellow through tiny colored crystals. Quercitin is one of these phytochemicals known as a bioflavonoid, which is beneficial to the human body. For example, rutin along with quercitin has been used in other countries to treat hemorrhoids and varicose veins. Quercitin is a bioflavonoid, which is showing promise to fight free radicals in the body and eliminate the damage they cause. Bioflavonoids are found in food and these foods help the body heal, but sometimes a supplement is necessary to get the amount that is needed for its anti-inflammatory and antihistamine properties.

Using Quercitin to help allergies and asthma

Quercitin can be a potent inhibitor of histamine release, which is known to cause the symptoms of allergies and asthma. When you hear the statement that "an apple a day keeps the doctor away," this can relate to how quercitin, which is found in apples helps to alleviate the sneezes, runny nose and congestion that makes allergies and asthma a nuisance. Other foods that are quercitin-rich are onions, red wine, tea, leafy green vegetables and fruits that are in the citrus family.

Quercitin is a natural remedy for varicose veins

Your legs have valves, which open letting the blood flow to the heart and later shut so gravity will not let the blood flow back into the leg. However, if these sensitive valves break, the blood collects in the vein and causes a varicose vein. Veins have different appearances, from a small spider vein to large unsightly veins that swell and ache. Ingesting quercitin will help treat and prevent varicose veins by improving the health of the connective tissues and capillaries. Supplements will act quicker in this situation, taking 500 mg a couple times per day.

Relieving the inflammation of IC and prostatitis

Some women suffer with an inflammatory condition of the bladder called interstitial cystitis. There is bladder pain and urinary urgency without the bacteria that is prevalent with cystitis. There has been studies and research where bioflavonoids, especially quercitin, have helped to relieve these symptoms. There is a product called CystoProtek, which many urologists suggest to women with this problem that contain bioflavoids. Even though they are not sure which specific element does the trick, since it contains quercitin many doctors feel this supplement is helpful

Men, on the other hand, suffer with inflammation of the prostate, which is called prostatitis. One study conducted showed relief when taking this bioflavonoid supplement versus the placebo.

A possible cancer preventative

Researchers have conveyed that eating a lot of fruits and vegetables is a way to prevent certain types of cancer. Bioflavonoids, including quercitin has been shown in this research to quell the growth of many cancer cells. The cancers studied were breast, ovarian, endometrial, colon, prostate and tumors of the lung.

The bottom line...

People taking blood thinners, corticosteroids, chemotherapy and other prescription medications should talk with their doctors before supplementing with quercitin. And of course eating the quercitin-rich foods is definitely a way to get this bioflavonoid into your body without any worries.
