【Latin Name】 Vitis Vinifera L.
【English Name】Grape Seed
【Origin & Technology】 Grape Seed extract is an extract from the seed of grapes. The seed
is left over from the production of wine or juice are harvested,
ground and extracted. They have a high content of compounds known
as OPCs (oligomeric proanthocyanidins). Since French researcher,
Dr. Jack Masquelier isolated OPCs from peanut skin in 1947, OPCs is
found in many plants and has been declared to be a potent
antioxidant of non-toxic, non-mutagenic, non-carcinogenic, and free
of side effects according to a review of numerous researches.

【Functions】 The antioxidant capacity of Grape Seed (skin) Extract comes from
proanthocyanidins (oligomeric proanthocyanidins) (OPCs). With an
antioxidant power 20 times stronger than Vitamin C and 50 times
stronger than Vitamin E , OPCs is known as a powerful antioxidant
to neutralize free radicals, which play a major role in
degenerative diseases, cardiovascular diseases, impaired vision,
sun damage and premature aging.
1. Cardiovascular Diseases
Researches have assured that OPCs helps strengthen capillaries,
arteries and veins, which endows it several important clinical
applications. OPCs appear to stabilize the walls of blood vessels,
reduce inflammation, and generally support tissues containing
collagen and elastin.
1). Atherosclerosis:
It has been proved that the oxidation of LDL plays an important
role in atherosclerosis. By its excellent antioxidant activity,
OPCs eliminates damages that free radicals, as well as collagenase
and elastinase do to the arteries, thus prevents or reverses
atherosclerosis. Animal evidence suggested that OPCs could slow or
reverse atherosclerosis.
2). Venous Insufficiency (Varicose Veins)
Varicose Veins refers to the situation when blood pools in the
legs, causing pain, heaviness, swelling, fatigue, and unsightly
visible veins. By strengthening capillary and reduce capillary
osmosis, OPCs can relieve the pain and swelling of venous
insufficiency. For the same reason, OPCs is recommended as a
treatment for hemorrhoids as well. There is also some evidence that
OPCs can be useful for the swelling that often follows injuries or
surgery. OPCs appear to speed the disappearance of swelling, by
strengthening damaged blood and lymph vessels that are leaking
fluid.
A double-blind placebo-controlled study of 92 subjects found that
OPCs, taken at a dose of 100 mg 3 times daily, significantly
improved major symptoms, including heaviness, swelling, and leg
discomfort. Over a period of 1 month, 75% of the participants
treated with OPCs improved substantially. Another
placebo-controlled study that enrolled 364 individuals with
varicose veins also found that treatment with OPCs produced results
superior to those of placebo.
3). Retinopathy/Vision Improvement
The capacity of OPCs in strengthening capillary and reduce
capillary osmosis is effective for patients suffering from stroke
and retinopathy. OPCs has been proved to improve retinopathy caused
by diabetics, atherosclerosis, inflammation and aging. It has also
been reported that OPCs can speed vision recovery after strong
light, and improve vision acuity of those who suffer from eye
fatigue because of long-time computer using.
A 6-week, controlled (but not blinded) study evaluated the ability
of grape seed (skin) OPCs to improve night vision in normal
subjects. In this trial of 100 healthy volunteers, those who
received 200 mg per day of OPCs showed improvements in night vision
and glare recovery as compared to untreated subjects.
2. Aging/Alzheimer Disease
Because OPCs can easily pass the Blood-Brain Barrier, it can
effectively inhibit the damage that free radicals do to the brain
organism, so that Alzheimer Disease is prevented and reversed.
3. Skin Care
Because of its antioxidant activity, OPCs is thought to prevent the
skin from excessive ultraviolet radiation and free radicals.
Considerable evidences indicate that OPCs protects and strengthens
collagen and elastin of the skin, so that wrinkle is prevented and
elasticity of the skin is ke
