Herb of the Week: St. John's Wort — Sunshine in Herb Form

St. John's Wort blooms around the summer solstice — the longest, brightest day of the year — and that timing feels intentional. This is an herb associated with light, warmth, and the lifting of darkness. It has been used for melancholy and despair for over two thousand years, and modern research has confirmed what healers throughout history already knew.

What Is St. John's Wort?

St. John's Wort (Hypericum perforatum) is a wildflower with small yellow blooms that appear to have tiny dots when held up to light — those "dots" are actually oil glands containing the active compounds hypericin and hyperforin. It's native to Europe but grows freely across North America. It's one of the most studied herbs in the world.

What St. John's Wort Is Good For

• Mild to moderate depression — multiple meta-analyses show it is as effective as SSRIs for mild to moderate depression, with fewer side effects
• Anxiety — calming effects on the nervous system; helpful for anxious depression and seasonal mood changes
• Nerve pain — topically and internally, one of the best herbs for nerve damage, neuralgia, and sciatica
• Wound healing — St. John's Wort-infused oil is deeply healing for bruises, burns, and sore muscles
• Seasonal affective disorder — particularly effective for the low mood that comes with reduced light exposure

How to Use It

For mood: Standardized capsules (0.3% hypericin) — 300mg three times daily. Give it 4–6 weeks before evaluating effectiveness.

Tincture: Effective but must be made from fresh or freshly dried plant material — the active compounds degrade quickly.

Infused oil: The classic preparation for external use. Apply to bruises, sore muscles, nerve pain, and skin irritation.

Critical Drug Interactions

St. John's Wort is a potent inducer of liver enzymes and can significantly reduce the effectiveness of many medications including birth control, antiretrovirals, blood thinners, and antidepressants. If you take any prescription medications, consult a healthcare provider before using St. John's Wort. This is not a reason to avoid it — it's a reason to use it wisely.

A Spiritual Note

In European folk tradition, St. John's Wort was hung above doorways on midsummer's eve to protect against dark spirits and negative energy. Whether you hold that literally or metaphorically, there's something true in it. This is a plant that helps light find its way back in — into the body, into the mind, into the spirit. Some of us need that more than we admit.
