Pagoda tree (Sophora japonica) flower extract delivers rutin, a flavonoid antioxidant. This extract supports healthy venous circulation and helps keep capillaries strong.
Most people take it as a capsule or tablet, standardized to a set rutin content. Taking the extract with meals improves absorption.
Rutin can thin the blood mildly. If you take anticoagulant or antiplatelet drugs, or if you have surgery scheduled, check with a healthcare provider before using pagoda tree. Safety during pregnancy and breastfeeding has not been established.
