St. John's Wort

Hypericum perforatum

Late June means one thing on the farm.......

It's St. John's Wort season.

Since St. John's wort is best when harvested and made into remedies when fresh, I look forward to this harvest every year. There's something about walking in a sunny field and gathering the bright yellow flowers scattered among the other herbs and flowers.

Harvest days are some of my favorite days. They remind me that good herbal medicine doesn't begin in the apothecary. It starts outside, paying attention to the plants and their stages of growth in order to harvest them when they are at their peak. I have had my eye on the St. John's Wort for weeks, marking where it is growing and visiting it often.

Meet the Plant

St. John's Wort is one of those plants that rewards those who look closely.

Hold one of the flower petals or leaves up to the light and you'll notice tiny translucent dots scattered throughout it. Those little oil glands give the leaves and petals the appearance of being full of tiny holes, which is where the name perforatum comes from.

Now gently squeeze one of the fresh flower buds between your fingers. Within seconds, your fingertips begin turning a beautiful, deep crimson. The first time you see it happen, it's almost magical. It never gets old......

Get to Know Her

St. John's Wort usually reaches peak bloom around June 24th, the traditional Feast of St. John the Baptist. That's where the plant gets its common name and why many herbalists still associate it with the height of summer.

St. John's Wort has been woven into the fabric of European herbal tradition for centuries. Before we had laboratories and scientific journals, herbalists learned by careful observation. Watching when a plant emerged each spring, when it flowered, where it preferred to grow, how animals interacted with it, and what happened when it was prepared in different ways.

St. John's Wort has a fair bit of folklore attached to it.

Its bright yellow flowers, blooming near the summer solstice, made it a symbol of light during the longest days of the year. In many parts of Europe, bundles of St. John's Wort were gathered around the Feast of St. John the Baptist and hung in homes, barns, and doorways. People believed the plant represented protection, blessing, and the triumph of light over darkness, and it became closely associated with hope and the changing of the seasons.

Traditional herbalists prepared the fresh flowering tops in several ways. Fresh tinctures were valued because many believed the living plant captured qualities that diminished once it was dried. Infused oils, recognizable by their deep ruby-red color, became a staple in home apothecaries and were often kept alongside calendula, comfrey, and plantain oils as versatile herbal preparations for skin care in everyday life.

Historical texts from Europe describe St. John's Wort as a plant that belonged in nearly every household medicine chest. Rather than being reserved for a single purpose, it was appreciated as a broad, dependable botanical that earned its place through generations of practical experience.

Amazingly, herbalists across different countries often arrived at remarkably similar conclusions about this plant. They may not have shared modern scientific terminology, but they shared careful observation. This tradition of watching, learning, and passing knowledge from one generation to the next is one of the foundations of herbalism.

 

What Makes This Plant Different?

Fresh matters. That's probably the biggest lesson this plant teaches. The vibrant red pigments released from the fresh flowers begin changing soon after harvest. That's one of the reasons many herbalists prefer making fresh tinctures and infused oils whenever possible.

It is good to know how and when a plant is harvested and how quickly it should go from harvest to jar.

Taste & Energetics

How We Prepare It

When St. John's Wort is ready, the fresh flowering tops and leaves are harvested and processed as quickly as possible.

Watching an infused oil or tincture slowly turn ruby red over the following weeks never gets old to me. It is a sign that good things are being extracted for use. It is also a good reminder that plants are complex and that good herbal medicine takes time.  From seed to shelf or harvest to formula,  every batch is made in small quantities with careful attention to harvest timing, preparation, and quality from start to finish.

Growing & Harvesting

St. John's Wort loves sunshine. You'll often find it growing along field edges, open meadows, roadsides, and disturbed ground.

Harvesting happens after the morning dew has dried but before the afternoon heat begins stressing the plants. I collect the flowering tops and leaves from healthy plants.

Remember that good wildcrafting means leaving plenty behind for seeds and next year's growth. The goal isn't to take everything, just what is needed.

From Sherri's Apothecary

After all these years, I still get excited when St. John's Wort starts blooming.

One of the gifts herbalism has given me. Is learning to pay attention to the beauty of God's creation and let the plants tell you when they're ready. You can't rush them, and you won't be able to convince them to bloom because it's convenient for your schedule.

God built rhythms into His creation.  I'm reminded that health works much the same way. We live in a culture that wants everything immediately, but most of what lasts takes time and patience. Plants know that. Maybe we should too.

Safety Considerations

St. John's Wort is powerful and should be used thoughtfully. It is known to interact with several prescription medications by affecting how the body processes certain drugs. Individuals taking medications, those who are pregnant or nursing, and anyone with medical concerns should consult an appropriately qualified healthcare professional before using this herb.

Proper identification is essential. Never harvest or use a plant unless you are confident it has been correctly identified.
