Known since ancient times and associated to Bacchus, the god of wine and vine in Greek mythology, the grape is the fruit of the red vine, Vitis vinifera, whose leaves turn red as autumn approaches.

The fruit and seeds of the grape are used in phytotherapy and are rich in antioxidant molecules. They contain a large number of molecules, including polyphenols such as quercetin, rutin and kaempferol, anthocyanidins, tannins and proanthocyanidols, also known as OPCs. These different antioxidant molecules contribute to the protection against free radicals, which are responsible for cell ageing.


OPCs have a protective effect on the blood vessels and an anti-inflammatory effect, particularly in cases of venous insufficiency.


Grapes are also known to contain resveratrol, a polyphenol that acts as a vascular protector. Resveratrol is at the origin of the "French paradox", a theory according to which the consumption of alcohol, and more particularly of red wine, would reduce the risk of cardiovascular disease. However, the abuse of alcohol is dangerous for health and should be consumed in moderation.

Grapes help to reduce bad cholesterol (LDL) in favour of good cholesterol (HDL), thus contributing to the prevention of cardiovascular disease. It is also a source of potassium, manganese and iron. While manganese is a cofactor involved in the functioning of enzymes, iron is involved in haemoglobin and in the transport of oxygen in the blood.

Grape polyphenols have also been studied for their effects on the brain, particularly in terms of memory, cognition, synaptic plasticity and neurogenesis, i.e. the production of new neurons, the number of which usually tends to decrease as we get older.


Grapes are a natural drainer that also contributes to the proper functioning of the nervous system. It contains natural antioxidants, including proanthocyanidols (OPC), which protect cells against free radicals. They also help to maintain the integrity of blood vessels and capillaries to promote venous circulation. Furthermore, the presence of resveratrol contributes to good cardiovascular health and promotes good blood pressure.
