Hypericum perforatum has been used for centuries in traditional medicine for the treatment of several disorders, such as minor burns, anxiety and mild to moderate depression.

It has been demonstrated that H. perforatum extracts and several of its major molecular components have the ability to protect against toxic insults: directly,  through neuroprotective mechanisms and indirectly, through is antioxidant properties. H. perforatum has therefore the potential to become an effective neuroprotective therapeutic agent. The effectiveness of H. perfpratum as an antidepression agent is particularly well studied, and the underlying mechanisms are well understood. [1, 2, 3,]

Hypericin is the main antidepressant constituent of H. perforatum, stimulating capillary blood flow. [4] Hypericin potential for antitumoral photodynamic therapy has been explored in several studies as it is probably the most powerful photosensitizer found in nature and for its specific properties, such as a strong absorption at longer wavelength, minimal dark toxicity, certain tumor selectivity and much higher clearance rate from the host body than hematoporphyrins. [3]

Hypericin has been shown to have a strong affinity for sigma receptors, which regulate dopamine levels. It also acts as a receptor antagonist at adenosine, benzodiazepine, GABA-A, GABA-B, and inositol triphosphate receptors, which regulate action potentials caused by neurotransmitters. [5]

Hyperforin is considered the antibacterial agent of H. perforatum. It inhibits the reuptake of many neurotransmitters and is a potent modulator of mitochondrial functions. [6] [7] [8]

Hyperforin inhibits serotonin uptake by elevating intracellular concentrations of sodium (Na) and calcium (Ca). [10]
