Hypericin is a naphthodianthrone, an anthraquinone derivative which, together with hyperforin, is one of the principal active constituents of Hypericum. Hypericin is believed to act as an antibiotic, antiviral and non-specific kinase inhibitor. Hypericin may inhibit the action of the enzyme dopamine beta-hydroxylase, leading to increased dopamine levels, although thus possibly decreasing norepinephrine and epinephrine.
