Pycnogenol

Natural substance from the group of leukoanthocyanidins or catechins. The substance is extracted from the bark of the pine, mostly from the French maritime pine - Pinus pinaster atlantica. Pycnogenol is soluble in water and ethanol but insoluble in ether.

Antioxidant, anti-edematous, antithrombotic, antihypertensive, antiallergic

Pykogenol in osteoarthritis: 3 major clinical studies have shown that taking pine bark extract improves arthritic symptoms. The dosage is based on the commercial preparation "Pycnogenol®" and is indicated as 100 mg to 150 mg pycogenol p.o./day pycogenol.

Pycogenol in bronchial asthma: Clinical and experimental studies postulate an anti-allergic and anti-inflammatory effect with improvement of pre-existing bronchial asthma.

Pycogenol for thrombosis: In a study of 198 passengers on long-haul flights, the effect of pine bark extract on the risk of thrombosis was examined 15. The study participants received either 2 x 100 mg p.o. pycogenol or placebo 2-3 h before departure. The sonographically determined thrombosis rate could be significantly reduced by taking pykogenol (see alsotravel thrombosis).

Pycogenol in chronic venous insufficiency (CVI): Several studies refer to chronic venous insufficiency (CVI). There was an improvement in leg swelling.
