So Who Is Saint John?


St. John’s Wort is so named because of the timing of the plant’s blooms – on or around St. John’s Day. This is actually a Christianized name referring to St. John The Baptist.

Medicinal Uses

St. John’s Wort has long been used in herbalism and traditional medicine. Its uses span from mental health support to treating wounds during the crusades.


The medicinal parts of the plant are above ground – meaning the stem, the leaves, and the flowers. Scientific studies have shown that the main chemicals at work in this plant are hypericin and hyperforin. These compounds can affect serotonin and dopamine in the brain. As such, Saint John’s Wort is often used in holistic treatments for mild to moderate depression, insomnia, and anxiety.

Steep On It


St. John’s Wort can be consumed in a variety of ways: tea, tincture, oil, dried herb, and salves are the most common. Many herbalists recommend using it fresh for optimal vitality. You can steep 2-3 teaspoons of the flowers in hot water for 4 minutes. Strain out the flowers before drinking and you’ve got a steaming cup of medicine in your hands! However, it isn’t overnight magic, exactly. Some herbalists caution that this powerful plant can take up to 4-6 weeks to work and alleviate particular symptoms. 


An important thing to note: this plant can cause serious side effects when used in combination with other medications.

Keeping St. John’s Wort in Your Garden


As a vigorous, invasive perennial plant, St. John’s Wort won’t be a difficult herb to incorporate into your garden. Plant your seeds or starter plant in sun or partial shade. Plants should be spaced about two feet apart from one another. Water regularly. This plant appreciates moisture but doesn’t want to be soggy for long periods of time. 


In order to keep this plant under control, you’re going to have to stay on top of things and watch the plant’s development closely. You can remove the flowers with shears in order to use them in medicinal ways. Make sure you do so before the plant berries, in order to prevent new seeds from forming. As little seedlings pop up, weed them out. 


When pruning this perennial plant to your desired size and shape, use those clippers in early spring – but don’t go too wild with it. The stalks you clip in the spring will not flower in the growing season. 


Before planting, do some research on St. John’s Wort in the area where you are living. If it is dangerously invasive and wreaking havoc on the ecosystem, consider planting something else in your garden, while foraging Saint John’s Wort in areas where it already grows. This can be an exciting scavenger hunt, with the added bonus of fighting back a plant that may be out-competing native pollinators in your area.
