How Bilberry Works?

The most effective parts of Vaccinium myrtillus are the leaves and fruit. The dried, ready fruit consists of tannins and a variety of anthocyanidin (anthocyanoside) constituents such as delphinidin, malvidin, cyanidin, petunidin, peonidin, and others. Anthocyanidin concentration ranges from 300 mg - 700 mg every 100 grams of fruits but content may depend on region of production. Clinical experiments suggest that these constituents are broadly distributed in the whole body after oral administration and are removed by the kidneys. After usage of a particular extract of bilberry (Bilberon 25, Tokiwa Phytochemical Co.), containing 15 diverse anthocyanidins, peak plasma concentration was accomplished within 15 minutes in an animal model. Bioavailability for the anthocyanidins ranges between 0.61% - 1.82%. For all anthocyanidins, combined, bioavailability was 0.93%. Bilberry leaves also consist of flavonoids such as quercetin; polyphenols such as resveratrol and a comparatively high concentration (9.0 ppm) of chromium. Raw bilberry fruit may include higher amount of a few constituents when compared to cooked bilberry. Heating bilberries, for 18 minutes at 190°C, leads to loss of 17% - 46% of resveratrol constituent because of degradation. Anthocyanidins in bilberry are thought to have number of natural impacts such as decreasing vascular permeability, increasing the synthesis of glycosaminoglycans, aiding in the redistribution of microvascular blood flow, reducing basement membrane thickness and the formation of interstitial fluid. An anthocyanidin pigment found in bilberry fruit may have gastroprotective and anti-ulcer effects. According to some laboratory research, anthocyanidins have anti-edema and anti-inflammatory effects. Initial research confirms that a bilberry leaf extract may have triglyceride, blood glucose and cholesterol lowering effects.

What Are The Side Effects /Adverse Reactions of Bilberry?

There is no significant side effect reported due to oral or topical consumption of bilberry powder.

How Bilberry Interacts With Other Herbs and Supplements?

Herbs and Supplements Containing Chromium Effects - There is significant amount of chromium in bilberry, which can enhance the potential risks of chromium toxicity when taken with chromium containing supplements or herbs such as cascara, brewer's yeast or horsetail. Herbs and Supplements with Hypoglycemic Potential - Bilberry leaves may have additive impact in human being with herbs that reduce the blood glucose levels. Herbs with hypoglycemic potential include fenugreek, devil's claw, guar gum, garlic, Panax ginseng, horse chestnut, Siberian ginseng, psyllium and others.

How Bilberry Interacts With Drugs?

Antiplatelet or Anticoagulant Drugs - Interaction rating between bilberry powder and drugs with Antiplatelet / Anticoagulant properties is moderate, so be careful while using this mixture. Initial studies recommend that anthocyanidin from bilberry can inhibit platelet aggregation. Combination of bilberry and anticoagulant and antiplatelet drugs may enhance the potential risks of bleeding. Some of these drugs include clopidogrel (Plavix), aspirin, enoxaparin (Lovenox), dalteparin (Fragmin), indomethacin (Indocin), heparin, warfarin (Coumadin), ticlopidine (Ticlid) and others. Antidiabetes Drugs - Interaction rating between bilberry powder and anti-diabetic drugs is moderate so be careful while using this combination. Initial clinical studies on animal models suggest that leave extract of bilberry leaf may have blood glucose lowering activity. Utilization of bilberry leaves may require dose adjustment of anti-diabetes drugs so dosage should of such patient should be regulated closely.

How Bilberry Interacts With Foods?

Not known.

How Bilberry Interacts With Lab Tests?

Blood Glucose - Bilberry powder may result in lowering of blood glucose and related test results. Initial experiments suggest that a bilberry leaves extract may have blood glucose lowering activity. Triglycerides - Leaves of bilberry may decrease the serum triglycerides and related test results. Initial experiments suggest that particular extract of bilberry leaves may have triglyceride lowering activity.

How Bilberry Interacts With Diseases and Conditions?

Diabetes - Vaccinium myrtillus may play its role in reducing blood glucose. According to initial studies, bilberry leaves extract may have blood glucose lowering effects; therefore blood glucose level of such patients should be monitored carefully. Surgery - Bilberry may interfere blood glucose levels. Bilberry may alter the blood glucose control during surgical procedures. Therefore, patients should stop using bilberry minimum two weeks before their suggested surgical procedures.

What Should Be the Dose/Administration of Bilberry?
