Herb of the Month: Grape Seed (Vitis Vinifera)

Author: Angelique Bone   Date Posted:1 May 2019 

Grapes and grape leaves have a long history of use in Greece to help promote health. In the 1970’s, Grape seed extract was developed, ¹ and it is now one of the main sources or oligomeric proanthocyanidin compounds. ²


One of the main functions Grape Seed is commonly used for is as an antioxidant. It is able to scavenge free-radicals, preventing damage to cells, and this effect has been shown to be stronger than that of Vitamins C and E. It also seems to help the amount of vitamin E which is lost through the neutralization of free radicals. ²


Grape seed also helps to improve blood flow and assists poor circulation, aiding in the relief of cold hands and feet.³ Evidence also supports the use of this herb to help reduce fluid retention in women who get this symptoms pre-menstrually.² It also has a strengthening effect on capillary walls and can support minor wound healing, due to grape seed containing compounds which assist with the cross-linking of collagen fibres. ²



Since Grape Seed has a strong antioxidant effect, and also exerts an anti-inflammatory effect, it seems reasonable that it would also be of benefit in supporting heart health. A Meta-Analysis of controlled trials found that Grapeseed did indeed offer some support for a healthy heart, though further trials would be beneficial. ⁴


Grapeseed is available as a single ingredient supplement or it can also be found in combination antioxidant formulas. Some women’s multivitamins also contain grapeseed for added health benefits.
