A flowering plant also known as red clover. It is commonly used in alternative medicine due to its ability to affect blood flow and coagulation.

Red clover is used in some lubricants as a sexual enhancement ingredient, usually in coordination with other herbal extracts. There is limited research regarding trifolium pratense’s effectiveness as a libido-enhancing agent; however, it does contain isoflavones, chemicals that can affect inflammation.

It is generally safe, but large doses can cause some side effects including topical irritation and upset stomach.
