Did you know that there are numerous herbs named after popular religious figures? One example is the St. John's Wort (Hypericum perforatum) plant.1 This herb is named after St. John the Baptist, since it's usually in full bloom by June 24, the saint's feast day.

St. John's Wort has wild yellow flower2 clusters with oval and elongated petals,3 while the plant itself is shrubby and has pale green leaves.4 Although primarily found in Europe, St. John's Wort has since spread to the Americas, Russia, Asia, China and the Middle East.5

The plant blooms in June to August in uncultivated ground, woods, hedges, roadsides and meadows. Once St. John's Wort grows, many small, round and black seeds appear that have a resinous smell and are stored inside a three-celled capsule.6

Important Benefits of St. John's Wort

Undeniably, St. John's Wort's antidepressant effect is its strongest point. The herb contains a rare combination of antidepressant chemicals that prevent or delay the reuptake of hormones serotonin, dopamine and norepinephrine, thereby reducing depressive symptoms.

St. John's Wort also works in combatting anxiety and mood swings and in delivering additional energy and pleasure.7,8 This herb may be ideal for people with Seasonal Affective Disorder or SAD, a condition that occurs during the winter months because of a lack of sunlight and goes into remission during the spring and summer months.9

St. John's Wort aids in enhancing your metabolism and internal clock to battle sleeplessness, irritability and chronic fatigue, and in removing chronic stress hormones from the body, boosting health and cognitive function.

This herb is also beneficial for women's health, since it helps reduce sensitivity of pre-menstrual symptoms, improves conditions of women having pre-menstrual and menopausal mood swings and helps alleviate pregnancy-related hemorrhoids or other stretched out areas of the body.

St. John's Wort regulates hormonal activity, too, since its active ingredients have strong effects on hormone regulation. The herb can lessen hypothyroidism symptoms and aids the thyroid gland in producing adequate amounts of hormones.

St. John's Wort's soothing nature and rich concentration of antioxidant and anti-inflammatory compounds can ease pain caused by arthritis, gout, joint discomfort and muscle aches, and help reduce inflammation of the cardiovascular system, helping lower blood pressure levels and stress levels on the heart.

Plus, if you or someone you know is struggling with withdrawal symptoms against cigarettes, alcohol or other addictive substances, St. John's Wort may curb these addictive tendencies. However, studies are still being conducted on this. Other known health benefits of St. John's Wort include:

Fighting viral infections — New research highlighted that St. John's Wort could prevent or reduce risk for viral conditions like AIDS and hepatitis. A caveat to this is the high dosage needed for the antiviral effect to take place, raising a person's risk for numerous side effects. Additional research is still needed to determine the proper balance.

What Are St. John's Wort's Uses?

St. John's Wort was used as folk medicine for the wounded, especially by the Knights of St. John during The Crusades. During Medieval times, St. John's Wort was used to drive out the "inner devil" in people. Meanwhile, a Swiss alchemist and doctor,10 Paracelsus, recommended St. John's Wort to be used against hallucinations.11

However, St. John's Wort's history of medicinal use actually dates back even further to ancient Greece, where its flowers and leaves were used as a medicine.12 Nowadays, St. John's Wort is common in European countries such as Germany as a natural antidepressant, although therapeutic use is now growing in other parts of the world.

The herb is also used topically via salves or tinctures to speed up the healing process of burns, bruises and scrapes. St. John's Wort stimulates circulation of oxygenated blood to those skin cells to stimulate repair.13,14 St. John's wort's leaves and flowers are harvested, dried and used either as a liquid or tincture, or as a tablet or capsule.15 Herbalists typically use a fluid extract, although St. John's Wort tea and oil are available, too.16,17

You can also take a muslin cloth, soak it in the oil and apply to the area for an hour. Dab the cloth several times onto the skin during the day.

Faster healing of cuts, scrapes and/or scratches — This is one of St. John's Wort oil's advantages. Plus, the oil's anti-inflammatory capabilities lessens redness and inflammation. Just apply the oil at home because it can attract dirt that could possibly cause an infection.
