How to identify St. John's wort

Hypericum perforatum, commonly known as Saint John’s wort is a perennial plant with yellow flowers and is used in both traditional European medicine and in folk herbalism. The origin of this plant dates back to its use by the ancient Greeks. The plant blooms around the feast time of St. John Baptist in late June and thereby gets its name. 

Characteristics to help you identify Saint John’s wort plant:

Saint John’s wort plant is characterized by black dots on the edge of five yellow flower petals.  These are often found on the leaves as well. It belongs to Hypericaceae family with average flower size of about one inch (2-2.5 cm). Flowers are bright yellow with 5 petals; leaves are usually small and opposite with 1-2 inches size. It usually grows from June to August and attains maximum height of 2 feet (60 cm). 

The species name “perforatum” refers to the fact that the leaves of the plant are “perforated” or appear to have tiny pin holes –tiny oil glands — which are only visible upon close inspection.

If ever you are unsure whether you’ve found St. John’s Wort, simply hold a leaf up to the light.  If you can see right through numerous translucent holes that look like pin pricks, then you’ve most likely found St. John’s Wort. 

Another test to conduct to be sure that the plant in question is indeed St. John’s Wort is to squeeze a flower and bud between your fingers.  If it’s St. John’s Wort, it will release a reddish or purplish oil.

A Natural Ally for Calm and Restful Sleep:

The extracts of St. John’s wort are often used to support a sense of calm and promote better sleep.

Studies suggest that St. John’s wort may help improve the brain’s use of neurotransmitters like serotonin, dopamine, gamma-aminobutyric acid (GABA), and norepinephrine. This improved neurotransmitter function can contribute to an overall sense of wellbeing and may help reduce feelings of stress and restlessness.

While there aren’t many long-term studies on St. John’s wort for stress relief, existing research is promising. Some studies have shown that St. John’s wort can positively influence emotional responses to negative stimuli in as little as seven days.

St. John’s wort may also aid sleep by supporting the production of the body’s sleep hormone, melatonin.

How to Use St. John’s Wort

For those looking to use St. John’s wort for calming effects or to promote restful sleep, it is best consumed as a tincture or tea. Unlike many herbal remedies that can be made with dried herbs, St. John’s wort is most effective when used fresh. Dried St. John’s wort loses much of its potency, so fresh preparation is key. Making a tincture or tea from fresh St. John’s wort ensures you get the maximum benefits.
