Herbal substances that affect hemostasis

Abstract

The use of naturally occurring plants, which have been used for thousands of years by humans for their medicinal properties, is steadily growing in popularity. Their pharmacologically active constituents which confer medicinal benefit also pose risks, including the potential for causing or contributing to bleeding. This is especially problematic in patients undergoing surgery or procedures as the unrecognized bleeding potential of many natural substances could lead to perioperative hemorrhage and related complications. Perioperative practitioners should understand the importance of completing a full medication review preoperatively which includes disclosure of natural substances. An understanding of the bleeding risks of these substances should also be appreciated.
