The purpose of this site is to collect lab research by medical doctors about herbs that are proven to treat illnesses and counter the false attacks on herbs by the medical industry and false claims by alternative medicine. I let the science tell the facts.

Proanthocyanidins, Procyadidins

Procyadidin according to the following research reports has tremendous antioxidant and healing properties. The old wives tale "An apple a day will keep the doctor away" is proven to have scientific validity. Delicious and Granny Smith apples, green tea and other herbs have proanthocyanidins.

Some of its health effects are increased oxigen, lessening of heart and arterial problems, increased anti-oxidants, and many other remarkable benifits. see item 5 below.

1. Wickipedia "Proanthocyanidin (PA or PAC), also known as procyanidin, oligomeric proanthocyanidin (OPC), leukocyanidin, leucoanthocyanin and condensed tannins, is a class of flavanols. Proanthocyanidins are essentially polymer chains of flavonoids such as catechins.[1] One was discovered in 1948 by Jacques Masquelier and called Vitamin P, although this name did not gain official category status and has since fallen out of usage. It was Masquelier who first developed techniques for the extraction of proanthocyanidins from certain plant species."

2. "Proanthocyanidins can be found in many plants, most notably apples, pine bark, cinnamon, grape seed, cocoa, grape skin, and red wines of Vitis vinifera. However, bilberry, cranberry, black currant, green tea, black tea, and other plants also contain these flavonoids. The berries of chokeberry, specifically black chokeberry, have the highest measured concentrations of proanthocyanidin found in any plant to date.[2][3] [4] Apples contain on average per serving about eight times the amount of proanthocyanidin found in wine, with highest amounts found in the Red Delicious and Granny Smith varieties... Proanthocyanidins suppress production of a protein endothelin-1 that constricts blood vessels.[8] These studies provide data supporting the French Paradox which hypothesizes that intake of proanthocyanidins and other flavonoids from regular consumption of red wines prevents occurrence of a higher disease rate (cardiovascular diseases, diabetes) in French citizens on high-fat diets...Common antioxidants currently used are vitamin C and vitamin E; however, studies show that proanthocyanidins antioxidant capabilities are 20 times more powerful than vitamin C and 50 times more potent than vitamin E [9]. Proanthocyanidins found in pine bark and grape seed extract work directly to help strengthen all the blood vessels and improve the delivery of oxygen to the cells. Proanthocyanidins also have an affinity for cell membranes, providing nutritional support to reduce capillary permeability and fragility. Although flavonoids are widespread in nature, the powerful proanthocyanidin compound is most abundant and available from the bark of the maritime pine and in grape seeds, or pips.
* Proanthocyanidins reduce histamine production, and are used in the treatment of allergies.
* Proanthocyanidins help improve circulation by strengthening capillary walls. This is especially important for people with compromised circulatory systems, such as stroke victims, diabetics, arthritics, smokers, oral contraceptive users and people with general cardiovascular insufficiencies.
* Proanthocyanidins inhibit enzymes that break down collagen. Proanthocyanidins help collagen repair. The breakdown of collagen is what causes our skin to lose its elasticity which in turn causes wrinkles. Proanthocyanidins help keep skin elastic, smooth and wrinkle-free. Proanthocyanidins are also taken as an oral cosmetic to help in the prevention of wrinkles.
* Proanthocyanidins act as an internal sunscreen. Inhibiting the daily effects the Sun's rays have on our skin.
* Proanthocyanidins cross the blood-brain barrier to protect the blood vessels in the brain.

3. Proanthocyanidins cross the blood-brain barrier. This enables proanthocyanidins to fight free radicals in the vessels of the brain that in turn will help them remain healthy. This can result in increased mental acuity, a decreased potential for stroke, and possibly in fighting senility."

5. In Eating For Diving Fitness: The Lesser Known Antioxidants - Part IV: Proanthocyanidins by Gary L. Taylor, Technical IT, etc. he states the following benifits;
Boost immune system
Protection from arteriosclerosis
Enhance connective tissue health
Reduces lipid peroxidation
Boosts the effects of vitamin C
Lower cholesterol levels
Reduces inflammation & edema
Reduced cancer risk
Reduced risk of stroke and heart attack
Effective antioxidant for brain & nerve tissue
Possible arthritis reduction and relief
Helps prevent inflammation of lung tissues
Potential anti-aging benefits
Reduction & repair of UV damage to cells
Reduction of muscle cramps
Potential for reduction of diabetic retinopathy
*** Appears to enhance and augment the antioxidant properties of vitamins E, C, and A.
