What is St. John's Wort Powder?

St. John's Wort Powder is the finely ground aerial parts of Hypericum perforatum, the bright yellow-flowered perennial in the family Hypericaceae. It is the same material as our cut-and-sifted St. John's Wort, milled for encapsulation and blending.

About the plant

The plant is named for its peak bloom around the feast day of Saint John the Baptist on June 24, and its species name perforatum comes from the tiny translucent glands that dot the leaves. Native to Europe and parts of Asia, it is among the most researched herbs in modern pharmacology, with hypericin, hyperforin, and flavonoids as its studied constituents. It is well documented that hyperforin induces cytochrome P450 liver enzymes, so St. John's Wort is known to interact with many prescription medications; consult a healthcare provider and pharmacist before combining it with any medication.
