Introduction

St. John’s Wort was touted as the “happy herb” of the 1990s as it was used to treat depression and anxiety. In recent years St. John’s Wort has also shown promise as a remedy for damaged nerve endings. If you suffer from nerve pain or damage, insomnia, stress, mild (to moderate) depression and anxiety, fibromyalgia, chronic fatigue or seasonal affective disorder then St. John’s Wort may be able to help (Gladstar, 2014) (Easley & Horne, 2016).

St. John’s Wort belongs to the Hypericaceae plant family and is a perennial that grows to 80 cm in height. St. John’s Wort has bright yellow flowers that appear in flat-topped clusters. St. John’s Wort thrives in temperate climates across the globe and is normally harvested in summer (Chevallier, 2016).

Scientific Research

Resources by Ng, et al., 2017 and Coppock & Dziwenka, 2016 present the findings of clinical studies completed on St. John’s Wort in humans. These findings are summarised below:

  1. The results of numerous clinical studies suggest that St. John’s Wort could be considered a viable alternative to SSRIs for mild to moderate depression as it has similar results, fewer side effects and a lower risk of discontinuation (or dropout).
  2. Clinical studies have suggested that St. John’s Wort may control postoperative pain.
  3. St. John’s Wort was seen to increase the duration of deep sleep across numerous studies.
  4. Meta-analyses have shown that St. John’s Wort is an effective treatment for menopausal discomfort with few side effects.
  5. Topical preparations of St. John’s Wort have shown antimicrobial activity.

Preparations & Dosage

Infused oil – apply topically to bruises, sprains, burns and injuries of all kinds. Infuse 70% St. John’s Wort flowers and 30% St. John’s Wort leaves in olive oil (in a 1:4 ratio) for 2 to 6 weeks (Gladstar, 2014) (Chevallier, 2016) (Easley & Horne, 2016).

Infusion – pour 1 cup of boiling water over 1-2 tsp of dried herb and infuse for 10-15 mins. Take 100-240 mL 1-4 times a day as a digestive tonic (Easley & Horne, 2016) (Chevallier, 2016).

Tincture – take 5 drops to 3 mL 3 times a day of a 1:2 ratio tincture (containing fresh plant material and 95% alcohol) (Easley & Horne, 2016) (Chevallier, 2016). Take 2-4 mL 3 times a day of a 1:5 ratio tincture (containing 40% alcohol) (Hoffmann, 2003).

Capsule – take 500-1 500 mg 3-4 times a day (Easley & Horne, 2016).

Cream – for cramps or neuralgia rub onto the affected part (Chevallier, 2016)

Note that tinctures and infusions prepared from fresh, good-quality herbs will turn a deep red. If the colour does not turn red then it is an indication that the plant material is old, of poor quality or the wrong species of St. John’s Wort (Easley & Horne, 2016).

Safety Considerations

In the past there were concerns that St. John’s Wort worked similarly to a monoamine oxidase (MAO) inhibitor, but recent findings have disproved this theory. This means that St. John’s Wort doesn’t have the same restrictions as MAO-inhibiting antidepressants (Gladstar, 2014) (Brinker, 1998) (Gardner & McGuffin, 2013).

Contraindications

Empirical evidence suggests that St. John’s wort should not be consumed during pregnancy due to its emmenagogue, abortifacient and uterine stimulant effects and actions (Brinker, 1998).
St. John’s Wort should not be used during phototherapy (laser or ultraviolet) by fair-skinned persons, or when taking photosensitizing drugs (Easley & Horne, 2016) (Gladstar, 2014) (Chevallier, 2016) (Hoffmann, 2003) (Brinker, 1998) (Gardner & McGuffin, 2013) (Hoffmann, 2003) (Brinker, 1998).

Drug Interactions

If taken internally St. John’s Wort may decrease the therapeutic activity of some immunosuppressants, anticoagulants, antiarrhythmics, calcium channel blockers, anti-anginal, hormonal contraceptives, anxiolytics, antidepressants (tricyclic), antivirals, statins, anti-cancer drugs, beta-adrenergic blockers, hypoglycemics, antiulcer agents, antifungals, anticonvulsants, skeletal muscle relaxants and antihistamines (Chevallier, 2016) (Hoffmann, 2003) (Gardner & McGuffin, 2013). It is strongly advised that you consult with a qualified healthcare practitioner if you intend on taking St. John’s Wort while on other medication.
Avoid using St. John’s Wort when taking selective serotonin syndrome reuptake inhibitors (SSRIs) as it may result in serotonin syndrome. If you are considering switching from SSRIs to St. John’s Wort, implement a 3-week wash-out period for the SSRI before switching to St. John’s Wort (Easley & Horne, 2016) (Chevallier, 2016).

Adverse Events

Based on evidence from clinical trials, St. John’s Wort has been well tolerated, with no serious adverse effects reported (Gardner & McGuffin, 2013).
Evidence obtained from clinical trials also suggests that phototoxicity concerns, when taking St. John’s Wort, are not an issue for the general population. Caution is however advised for fair-skinned persons who experience excessive sunlight exposure.
