What is St. John's Wort Tincture?

St. John's Wort Tincture is an alcohol extract of Hypericum perforatum, the bright yellow-flowered perennial in the family Hypericaceae. The tincture has a characteristic deep red color that comes from the plant's hypericin content, the same compound that gives a traditional St. John's Wort infused oil its red hue. This is a 1:8 extract in a 47.5% alcohol solution.

About St. John's Wort

St. John's Wort takes its English name from its peak flowering around the feast day of Saint John the Baptist on June 24, and its species name perforatum from the tiny translucent glands that dot its leaves. Native to Europe and parts of Asia and now naturalized worldwide, it is among the most researched herbs in modern pharmacology. Its studied constituents are hypericin, hyperforin, and flavonoids.

Drug interaction note

It is well documented that hyperforin induces cytochrome P450 liver enzymes, and St. John's Wort is known to interact with a wide range of prescription medications. Consult a healthcare provider and pharmacist before combining this tincture with any medication.
