St. John's Wort

St. John's Wort Uses

St. John's Wort, named after St. John the Baptist, is a perennial herb native to Europe but found in many parts of the world today. Its cheerful yellow flowers, resembling mini-sunbursts, bloom around the summer solstice, adding colour to meadows and fields. Interestingly, St. John’s Wort flowers release a red pigment when crushed, a phenomenon aptly named "solar infusion." This quality symbolizes the sun's energy encapsulated within the plant. The St. John’s Wort plant gets its scientific name, Hypericum perforatum, from the Greek words "hyper" (above) and "eikon" (picture), alluding to St. John's Worts traditional uses as a protective charm hung above doors and windows.

The medicinal use of St. John's Wort dates back centuries. Notably, it was used by the Greeks to treat a variety of ailments, and throughout the Middle Ages, it gained a reputation as a herb with protective qualities. In traditional folk medicine, St. John's Wort was often used to alleviate conditions such as wounds, burns, and nervous disorders. 

A complex biochemical makeup lies at the heart of St. John's Wort's healing potential. The herb contains numerous bioactive compounds, including hypericin, hyperforin, and flavonoids. Hypericin, in particular, has garnered attention for its robust therapeutic effects, although the interplay of the various components (otherwise known as "synergy") is likely responsible for the herb's overall efficacy.

Key Health Benefits & Uses For St. John's Wort

While St. John's Wort has a rich historical tapestry, it still figures prominently in modern herbal medicine. Here are some of the most celebrated uses of St. John’s Wort today:

Antidepressant – St. John's Wort is renowned for its ability to alleviate mild to moderate depression and anxiety. In fact, many studies have shown that St. John's Wort is not only effective at fighting mild to moderate depression, obsessive-compulsive disorder (OCD), and anxiety by rebalancing neurotransmitters in the brain but also has far fewer potential side effects than most other prescription antidepressants, such as loss of sex drive. Also noteworthy is the fact that John's Wort is non-habit-forming.

Anti-Inflammatory – St. John's Wort possesses scientifically demonstrated antibacterial and anti-inflammatory effects. Indeed, research has shown that the active compounds in the plant, such as hyperforin and hypericin, can effectively help modulate the immune response and reduce pro-inflammatory cytokines while stimulating anti-inflammatory cytokines. This makes it a valuable remedy for osteoarthritis, rheumatoid arthritis, inflammatory bowel disease, asthma, gout, acne, eczema, dermatitis, and many other inflammatory disorders.

Antiviral – Research on the antiviral potential of St. John's Wort has shown that it possesses considerable antiviral properties against a whole host of viruses, but perhaps most notably, those affecting the respiratory tract, including infectious bronchitis. In recent years, it has also shown tremendous potential in studies as an antiviral agent against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. 

PMS & Menopause Symptom Relief – Given its demonstrated benefits in lifting moods and relieving depressive symptoms, it should come as no surprise that St. John's Wort is commonly recommended to soothe PMS and menopausal symptoms, most notably depression, chronic fatigue and hormonal imbalance. In menopause, in particular, research has shown that St. John's Wort supplementation may result in a substantial improvement in both psychological and psychosomatic symptoms in over 76% of women.

Skin Health – St. John's Wort's soothing and anti-inflammatory qualities have made it a popular remedy for skin ailments, including burns, wounds, and eczema. It can effectively relieve skin irritations, reduce redness, and promote overall health. St. John's Wort-infused oils, ointments, and creams are also ideal for topical application to aid in wound healing and alleviate symptoms of conditions like eczema, dermatitis, and others.

Who Should Consider Using St. John's Wort?

Incorporating St. John's Wort into one's daily regimen may be especially beneficial for individuals grappling with mood disorders, including mild to moderate depression, anxiety or mood swings. It may also be an excellent idea for those looking to support their neurotransmitter balance, such as serotonin, which plays a crucial role in mood regulation, and dopamine, which is intimately involved in pleasure, satisfaction and motivation.

Moreover, those dealing with seasonal affective disorder (SAD) may find John's Wort especially beneficial to tame symptoms such as lethargy, low mood and moodiness during the darker months. In addition, those trying to quit drinking may be interested in St John's Wort for its ability to reduce alcohol withdrawal symptoms and prevent cravings.

St-John’s Wort Supplement Varieties

St. John's Wort is available in various forms and potencies, including capsules and tablets, which offer a convenient and standardized dose. St. John's Wort is also frequently found in tincture form, which is convenient and portable and offers customizable dosing and ease of administration. Another advantage of tinctures is that the alcohol used for extraction is a highly effective solvent that can extract a broad spectrum of plant constituents, including water-soluble and alcohol-soluble compounds. This makes tinctures a superior way to capture all of the medicinal properties of a plant.

Herbal teas are another option that, while milder in effect, offers a soothing mode of administration. Oils, ointments, and salves infused with St. John's Wort extract are yet another option and ideal for topical use to address all sorts of skin conditions. 

Quality supplements typically specify the concentration of active compounds, such as hypericin, which indicates the formulation's quality and efficacy.

Final Considerations

Some individuals may experience mild and transient side effects, such as gastrointestinal discomfort, dizziness, or skin sensitivity to sunlight (photosensitivity).

 One of the most significant concerns is St. John's Wort's potential to interact with various medications, including antidepressants, birth control pills, and anticoagulants, reducing their effectiveness. Additionally, the herb may induce the metabolism of certain drugs, altering their blood concentrations and potentially leading to inadequate treatment outcomes. Individuals with pre-existing medical conditions, particularly those affecting the liver or with a history of bipolar disorder, should exercise caution when considering St. John's Wort, and consultation with a healthcare professional is essential to assess its safety and potential interactions. 

Pregnant and breastfeeding women are advised to avoid its use due to limited safety data in these populations.
