[A comparative study of the action on the hemostatic system of extracts from the flowers and seeds of the meadowsweet (Filipendula ulmaria (L.) Maxim.)].

Flowers and seeds of Filipendula ulmaria show a high level of anticoagulant activity. Their anticoagulant and fibrinolytic effects were demonstrated after per os administration of the extracts. The seed extracts exert equally high anticoagulating effects when administered in vivo and in vitro.
