Abstract

INTRODUCTION:

Over-the-counter herbal and alternative medicines are classified as dietary supplements and, unlike drugs, are not rigorously regulated by the United States Food and Drug Administration. Their potential adverse effects are often poorly characterized.

METHOD:

Red clover, dong quai, and Siberian ginseng are herbal compounds used for treatment of perimenopausal symptoms such as hot flashes. These compounds are known to contain coumarins, and thus carry the potential for hemorrhagic complications; however, no cases of intracranial hemorrhage have been reported.

DISCUSSION:

We report a 53-year-old woman with spontaneous subarachnoid hemorrhage due to the use of an herbal supplement containing red clover, dong quai, and Siberian ginseng.
