Pine Bark Extract May Help Blood Circulation in People With Deep Vein Thrombosis

Deep vein thrombosis is when a blood clot forms in the deep veins of the body, usually the legs.


A recent study suggests that taking a French maritime pine bark extract, also known as Pycnogenol, may help improve blood circulation in people with deep vein thrombosis.


Participants in the study included 815 people who had deep vein thrombosis and post-thrombosis symptoms. They were offered either standard treatment, consisting of compressed socks and control of thrombotic risk factors or standard treatment, as well as an intervention. The interventions offered were aspirin, ticlopidine, sulodxide, and Pycnogenol.


At the conclusion of the study, the researchers noted significantly lower incidence of recurrent thrombosis in the intervention groups, with the Pycnogenol group have the greatest reduction. That group had 5.8% incidence, compared with 17.2% in the control group. They also noted 6.5% incidence of post-thrombosis symptoms in the Pycnogenol group, compared with 19.8% in the control group. Finally, the Pycnogenol group had the lowest occurrence of thrombotic events, when compared with the other test groups.


Researchers from CH-PE University in Italy led the study. It was published in the June 2018 issue of Minerva Cardioangiologica.
