St. John’s Wort Herb (Hypericum perforatum) – Dried Whole Herb

St. John’s Wort Herb (Hypericum perforatum) – Dried Whole Herb

Harvested at peak flowering from Hypericum perforatum, our dried St. John’s Wort herb retains the full spectrum of the plant’s naturally occurring phytochemicals — including hypericin, hyperforin, flavonoids (quercetin, rutin, kaempferol), and xanthones. Unlike standardised extracts, the whole herb delivers a broad-spectrum botanical profile consistent with traditional European herbal medicine practice, where the plant has been used for over 2,000 years as a nervine tonic and mood-supporting remedy.

Indicated For

• Mild to moderate low mood & emotional imbalance
• Mild anxiety & nervous tension
• Seasonal mood changes
• Sleep disturbance associated with nervous restlessness
• Topical support for minor skin irritations, bruising & nerve-related tension

Benefits

Hypericin & Pseudohypericin — Naphthodianthrone Compounds

Hypericin is the principal marker compound of Hypericum perforatum and has been extensively studied for its role in mood regulation. It modulates serotonin, dopamine, and noradrenaline reuptake, contributing to its antidepressant-like activity. A landmark meta-analysis in the British Medical Journal (Linde et al., 1996, updated 2005) analysed 37 RCTs and concluded that St. John’s Wort was significantly superior to placebo for mild-to-moderate depression and comparably effective to standard antidepressants with fewer side effects.

Hyperforin — Phloroglucinol Derivative

Hyperforin is the primary active constituent responsible for antidepressant and anxiolytic effects. It acts as a reuptake inhibitor of serotonin, dopamine, noradrenaline, GABA, and glutamate via a sodium conductive mechanism — distinct from conventional SSRIs. Research in Pharmacopsychiatry (Chatterjee et al., 1998) confirmed significant antidepressant effects in double-blind RCTs. The whole herb naturally contains hyperforin alongside synergistic flavonoids that may enhance bioavailability and activity.

Flavonoids — Quercetin, Rutin & Kaempferol

The flavonoid fraction of St. John’s Wort contributes antioxidant, anti-inflammatory, and MAO-inhibitory activity. Studies in Journal of Natural Products and Phytomedicine document the role of quercetin and kaempferol in modulating neuroinflammatory pathways and supporting mood regulation — compounds present in the whole herb but often absent or reduced in isolated extracts.

Sleep & Nervine Support

A study in Pharmacopsychiatry (Schulz, 2006) found St. John’s Wort improved sleep quality, increasing deep sleep stages and reducing nocturnal restlessness — consistent with its traditional use as a nervine relaxant and sleep herb.

Topical Anti-inflammatory Activity

Hypericin and flavonoids have demonstrated anti-inflammatory and wound-healing properties topically. Research in Journal of Ethnopharmacology supports traditional use for minor skin irritations, bruising, and nerve-related discomfort when infused in a carrier oil.

How to Use

As a Tea / Infusion:

1. Add 1–2 teaspoons (2–4g) of dried herb to a cup of freshly boiled water.
2. Steep for 10–15 minutes, covered, to preserve volatile compounds.
3. Strain and drink 2–3 times daily.
4. Consistent use for 4–6 weeks is recommended for full benefit.

Topical Infused Oil:

1. Pack a jar loosely with dried herb and cover completely with a carrier oil (e.g. olive or sunflower).
2. Leave to infuse in a warm, sunny spot for 4–6 weeks, shaking daily.
3. Strain and apply the infused oil to localised areas of skin irritation or muscle tension.
