Hypericin is a naturally occurring anthracene derivative found in plants of the genus Hypericum, the most well-known of which is St. John’s wort (Hypericum perforatum). This compound is known for its photosensitizing properties and is used in medicine and pharmaceuticals for its antidepressant, antiviral and anti-inflammatory properties.

Hypericin is used in the treatment of depression and anxiety disorders, acting as a reuptake inhibitor of serotonin, dopamine, and norepinephrine. Its antiviral activity makes hypericin a promising remedy for combating various viral infections, including herpes. Additionally, hypericin has anti-inflammatory properties, making it useful for treating inflammatory conditions.

When using hypericin-based preparations, it is important to follow your doctor’s recommendations, as this compound can cause photosensitivity — increased sensitivity to sunlight, which can lead to burns and skin irritation.
