It was from this plant that the isoflavone genistein was first isolated in 1899; hence the name of the chemical compound. The medicinal parts are the flowering twigs.

The plant has been used in popular medicine and herbalism for various complaints, including skin diseases, even in modern times.<ref>Template:Cite journal</ref><ref>Template:Cite book</ref><ref>Template:Cite book</ref>
