Proanthocyanidins

Clinical trial

Mechanism of Action

Vascular-protective compounds that reduce capillary permeability and fragility; relevant to varicose veins and chronic venous insufficiency

Uterine tonification; capillary integrity support via collagen cross-linking

Oligomeric tannins providing astringency and confirmed antimicrobial activity against common pathogens

Antioxidant oligomeric tannins in leaves; confirmed antibacterial properties studied for periodontitis prevention and influenza inhibition

Research Notes

HazelnutWestern

Oligomeric proanthocyanidins are well-studied vascular-protective compounds. Reduce capillary permeability and support venous integrity. Mechanism shared with grape seed and pine bark OPCs.

Partridge BerryWestern

Proanthocyanidins strengthen connective tissue and promote smooth muscle tonicity through collagen stabilization. Traditional pregnancy and postpartum use documented; modern evidence limited to observational reports.

SilverweedWestern

Proanthocyanidins provide astringent and antimicrobial activity. Well-characterised class of condensed tannins.

SorrelWestern

Proanthocyanidins from Rumex acetosa demonstrate antibacterial activity against periodontitis-causing bacteria and influenza virus inhibition in vitro.
