St. John’s Wort Extract
Description
St. John’s Wort Extract is obtained from the flowering aerial parts of Hypericum perforatum, a perennial herb native to Europe and North America. Traditionally, it has been used for centuries as a herbal remedy to promote emotional balance, relieve nervous restlessness, and support wound healing. It is now one of the most widely studied and used botanical extracts for mood support.
The extract is standardized to hypericins (≥0.3%) and hyperforin (≥2%–5%), the primary active compounds responsible for its antidepressant and mood-regulating activity. These constituents are believed to modulate neurotransmitters such as serotonin, dopamine, and norepinephrine, thereby promoting positive mood, emotional stability, and stress resilience. Modern research supports its role in maintaining mental well-being and nervous system balance.
Commercial production involves harvesting and drying of flowering tops, followed by aqueous–ethanolic extraction and purification. The resulting fine reddish-brown powder is stable under dry storage, soluble in ethanol, and partially soluble in water. St. John’s Wort Extract is widely applied in mood support supplements, stress management formulations, and functional wellness products.
