Xanthoparmelia is used to treat sexual dysfunction, especially erectile dysfunction (ED), as well as to increase sexual desire (as an aphrodisiac). It is also used for cancer.
Products containing xanthoparmelia are often marketed for sexual enhancement. In 2004, the US Food and Drug Administration (FDA) seized numerous brand name supplement products containing xanthoparmelia because these products also contained the prescription drug tadalafil (Cialis). This drug is used to treat erectile dysfunction (ED).
