Background

Sweet clover (Melilotus officinalis) is a plant native to Europe and now found throughout the world. Its flowering branch and leaf are used as medicine.

Sweet clover contains ingredients that might thin the blood and help wounds heal.

People use sweet clover for varicose veins, poor blood circulation, nerve pain in people with diabetes, bruises, and many other conditions, but there is no good scientific evidence to support these uses.

Don't confuse sweet clover with red clover. These are not the same.
When taken by mouth: Sweet clover is possibly safe when used appropriately. But it is possibly unsafe when used in large amounts due to the risk for liver damage and bleeding problems.
