What it Is

St. John’s Wort, botanically known as Hypericum perforatum, is a perennial herb characterized by its bright yellow, five-petaled flowers and small, oval leaves. If you hold a leaf up to the light, you might notice tiny translucent dots, which are oil glands. When crushed, the flowers release a reddish-purple oil, historically used for topical applications. This herb has a long history in traditional European herbalism, primarily for its mood-supporting properties and its external use for skin discomforts.

Did You Know?

The ‘Wort’ in St. John’s Wort comes from an Old English word for ‘plant.’ It gets its ‘St. John’s’ name because it typically blooms around St. John the Baptist’s Day, which is June 24th.

Ingredients

For St. John’s Wort tea, the primary ingredient is, naturally, the herb itself. You can use either fresh or dried flowering tops. For optimal potency, it’s generally recommended to harvest the flowering tops when the plant is in full bloom.

St. John’s Wort (flowering tops): Fresh or dried.
Water: Filtered water is preferred to avoid chlorine or other impurities that might affect taste or quality.

Approximate Measurements

The strength of your tea will depend on whether you’re using fresh or dried herb and your desired potency. Always start with conservative amounts and adjust as needed.

For Dried Herb: 1-2 teaspoons of dried flowering tops per 8 ounces (1 cup) of water.
For Fresh Herb: 1-2 tablespoons of chopped fresh flowering tops per 8 ounces (1 cup) of water.

Formula / Recipe: St. John’s Wort Infusion

This recipe focuses on creating a simple yet effective infusion, which is the most common way to prepare St. John’s Wort tea.

Step-by-Step Method

Measure the Herb: Place the measured dried or fresh St. John’s Wort into a heat-safe mug or teapot.
Heat the Water: Bring 8 ounces (1 cup) of filtered water to a boil.
Pour and Steep: Immediately pour the boiling water over the herb.
Cover: Cover the mug or teapot with a lid or a small saucer. This is a crucial step that many people skip, but it helps to retain the volatile oils and beneficial compounds that would otherwise escape with the steam.
Steep: Allow the tea to steep for 10-15 minutes. For a stronger infusion, you can steep for up to 30 minutes, but avoid steeping for too long as it can make the tea bitter.
Strain: Strain the herb out using a fine-mesh strainer or a tea infuser, leaving a clear, amber-colored tea.
Serve: Enjoy your tea warm. You may add a touch of honey or lemon if desired, though many prefer its natural, slightly earthy taste.

How to Use

St. John’s Wort tea is primarily consumed orally. It’s often used for its calming properties. While external use is also traditional (e.g., as a compress for skin), the tea form is usually for internal consumption.

Best Time to Use It

Many find it beneficial to drink St. John’s Wort tea in the morning or early afternoon. Due to its potential photosensitizing effects, it’s generally not recommended to drink it right before extended sun exposure, especially if you have fair skin.

How Often to Use

For general wellness support, one cup of St. John’s Wort tea per day is a common recommendation. Some individuals may opt for two cups, but it’s important to monitor your body’s response. Consistency is often key, but always observe the cautions section.

How to Buy / How to Choose Ingredients

Sourcing high-quality St. John’s Wort is essential for an effective and safe remedy.

Wildcrafting: If gathering yourself, ensure you correctly identify the plant (Hypericum perforatum) and that it grows in an area free from pesticides, herbicides, and heavy pollution. Harvest only the flowering tops.
Purchasing Dried Herb: Look for organic, sustainably sourced St. John’s Wort from reputable herbal suppliers. Ensure the product is freshly dried and hasn’t been sitting on shelves for years, as potency diminishes over time.
Avoid: Plants that show signs of mold, discoloration, or an unusual odor.

Storage

Dried Herb: Store dried St. John’s Wort in an airtight glass jar away from direct sunlight, heat, and moisture. A cool, dark pantry is ideal. It will retain potency for up to 12 months.
Prepared Tea: Brewed tea is best consumed fresh. If you must store it, refrigerate in a sealed container for no more than 24 hours. Reheating can diminish its quality.

Practical Tips

Use a good quality tea infuser: This prevents small herb particles from escaping into your tea.
Don’t boil the herb: Always pour boiling water over the herb, rather than boiling the herb itself. Boiling can destroy some delicate compounds.
Listen to your body: Pay attention to how St. John’s Wort affects you. Every individual is different.

Common Mistakes

Using the wrong plant: Mistaking Hypericum perforatum for other similar-looking plants can be dangerous. Always ensure correct identification if wildcrafting.
Boiling the herb: As mentioned, boiling can degrade valuable compounds. Infusion (pouring hot water over the herb) is the correct method.
Skipping the lid during steeping: Volatile oils are easily lost to evaporation, reducing the tea’s effectiveness.
Ignoring medication interactions: This is perhaps the most critical mistake. St. John’s Wort interacts with numerous medications.
Over-harvesting: If wildcrafting, only take a small portion of the plant from any given area to ensure its continued growth and sustainability.

Digoxin, cyclosporine, HIV drugs (protease inhibitors, NNRTIs), certain cancer drugs (irinotecan), triptans (for migraines).
