St. John’s wort is effective in treating depression—that’s common knowledge. But it also works against PMS, atopic dermatitis, and other ailments. Gentle and with proven efficiency.

We would like to provide you with an overview of the properties of this versatile medicinal plant.

Hardly any other medicinal plant has such a long and diverse history as St. John’s wort (Hypericum perforatum). Often referred to as a “natural antidepressant,” it remains a niche remedy – and quite undeservedly so. Because this plant packs a punch: whether for mild depression, hormone-related mood swings, or inflammatory skin conditions such as atopic dermatitis—St. John’s wort has demonstrated surprisingly broad effects in studies.

Active Compounds with Systemic Effects

This striking yellow-flowering plant contains a range of medically relevant compounds:

·       Hyperforin: inhibits the reuptake of serotonin, dopamine, and norepinephrine—acts as an antidepressant

·       Hypericin: mildly MAO-inhibiting, antiviral, and antimicrobial

·       Flavonoids and tannins: anti-inflammatory, antioxidant, astringent (tightens skin tissue)

This combination makes St. John’s wort a true all-rounder for both internal and external well-being.

St. John’s Wort Strengthens Our Largest Organ as Well as Our Psyche

Atopic dermatitis is more than just a skin problem. It is often accompanied by stress, sleep deprivation, and (severe) emotional strain—and this is where St. John’s wort has a dual effect:

·       Topically anti-inflammatory (through flavonoids and tannins)

·       Internally nerve-strengthening, mood-stabilizing, and stress-reducing

A study (Schempp et al., 2003) showed that a cream containing St. John’s wort led to significant improvements in atopic dermatitis—less itching, redness, and improved skin barrier.

It can also be used for small wounds, minor burns, and irritated skin.

Its effectiveness in treating mild to moderate depression is also well documented. A meta-analysis (Ng et al., 2017) concluded that St. John’s wort has comparable efficacy to common antidepressants, but with significantly fewer side effects.

Additionally, many individuals report improvements in:

·       nervous restlessness

·       irritability

·       sleep disturbances

·       seasonal affective disorder

Dosage: 600–900 mg of St. John’s wort dry extract per day, onset of effect usually after 10–14 days.

Herbal Support for Hormonal Balance

About three in four menstruating women suffer from premenstrual symptoms—both physical and emotional. Symptoms range from various types of pain to irritability, sleep problems, and depressive moods.

St. John’s wort can help here. In a placebo-controlled double-blind study (Canning et al., 2010), it was shown that St. John’s wort can significantly relieve PMS-related symptoms. St. John’s wort does not act hormonally, but through neurotransmitter modulation. And that’s exactly what makes it so effective for PMS.

Unlike sedatives (such as valerian), it is emotionally stabilizing. It helps the body return to its natural rhythm. In cases of difficulty falling or staying asleep due to inner unrest or hormonal fluctuations, St. John’s wort can be a gentle but effective option.

It may also represent a useful and gentle alternative for mild menopausal symptoms.
