Key Constituents
Red pigments historically used to standardise extracts; contribute to antiviral activity and are the compounds responsible for photosensitivity risk.
Considered the principal compound behind the antidepressant activity and the main driver of the herb's potent CYP3A4/P-glycoprotein induction and drug-interaction profile.
Antioxidant flavonoids contributing to overall activity.
A major phytochemical class of noni fruit and leaf, studied for antioxidant and anti-inflammatory activity.
Found mainly in the root and, at lower levels, the fruit; studied for anticancer and antimicrobial activity.
Fruit polysaccharides studied for gut-microbiota-modulating and anti-inflammatory effects in animal models of inflammatory bowel disease.
A phenolic coumarin found in the fruit, studied for anti-inflammatory and vascular effects.

Safety, Cautions & Contraindications
Significant drug interactions: strongly induces CYP3A4 and P-glycoprotein, reducing plasma levels of many drugs including oral contraceptives, antiretrovirals, cyclosporine, warfarin, and digoxin. May cause photosensitivity (fair-skinned individuals). Do not combine with SSRIs, SNRIs, or MAOIs (serotonin syndrome risk). Avoid in bipolar disorder.
Duke (2002) rates St. John's wort as ++ (raised from earlier editions) and notes antidepressant, antiviral, antibacterial, and wound-healing activities at experimental and clinical levels. Hypericin and hyperforin are identified as key active constituents. Clinical evidence (score 2) confirms antidepressant efficacy in mild-to-moderate depression, and WHO/Commission E provide approval for this indication. Dose: 300 mg standardized extract (0.3% hypericin, 3–5% hyperforin) three times daily. Duke emphasizes the critical drug interaction: St. John's wort is a potent CYP3A4 inducer and can significantly reduce blood levels of many medications including oral contraceptives, cyclosporine, antiretrovirals, and warfarin. Avoid combined use with SSRIs (serotonin syndrome risk) and pharmaceutical antidepressants (Duke, 2002).
Generally safe in moderate amounts. High potassium content — use caution in renal disease. Rare cases of hepatotoxicity reported with excessive consumption. May interact with warfarin (due to vitamin K content). Avoid during pregnancy.
Duke (2002) rates noni as +++ and notes analgesic, antirheumatic, antiarthritic, antitumor, antispasmodic, and hypotensive activities at the experimental level (score 1). Traditional Polynesian and South Asian medicine values it as a broad-spectrum tonic. The plant contains morindine, proxeronine, and damnacanthal, which are under investigation for immunomodulatory and anti-tumor effects. Duke notes that noni fruit can be consumed as food and is generally safe, though the juice has a strong unpleasant odor and taste. No significant toxicity has been reported with regular food consumption (Duke, 2002).

Botanical Description
Erect, branching perennial herb with paired, oval leaves dotted with tiny translucent oil glands that look like pinpricks when held to the light (giving the species name 'perforatum'). Bright yellow, five-petalled flowers with numerous stamens and black dots along the petal edges are borne in flat-topped clusters, and release a reddish pigment when crushed.[4]
Small evergreen tree or shrub (Rubiaceae), 3-10 m tall, with large, glossy, dark green, elliptical leaves marked by prominent parallel veins. Small, white, tubular, fragrant flowers are borne in dense rounded heads, developing into a compound fleshy fruit (syncarp) that is warty, semi-translucent and yellow-white when ripe, with a strong, pungent, cheese-like odour.[1]
Habitat
Grows in grassland, roadsides, woodland clearings and waste ground on well-drained soils; native to Europe, Western Asia and North Africa and widely naturalised elsewhere, including North America and Australia.[4]
Native to Southeast Asia and Australasia, and dispersed across the Pacific islands and into India and the Caribbean by early Polynesian voyagers and subsequent cultivation; grows in coastal areas, open and disturbed forest, and even on bare lava flows, tolerating poor, saline and drought-prone soils.[1, 6]
Harvesting
The flowering tops (flower and upper leaf) are cut in summer as the flowers open, around the traditional St John's Day period, and dried quickly in a warm, shaded, airy place to preserve the hypericin and hyperforin content.[4]
Ripe fruit is hand-picked as it softens and turns yellow-white, then traditionally left to further ripen or ferment for juice production; leaves and root are also traditionally gathered.[6]
Traditional Uses
St John's wort has a centuries-long European folk reputation as a wound-healing and nerve tonic herb, traditionally used for mild wounds, burns and nerve pain and to lift low mood; this traditional mood-supporting use is now one of the most extensively clinically studied applications of any herbal medicine, with standardised extracts shown comparable to conventional antidepressants for mild-to-moderate depression.[1, 4]
Noni has an extensive Polynesian, South Asian and Southeast Asian traditional-medicine history, used as a broad-spectrum tonic for pain, inflammation, infection and immune support, and traditionally for diabetes and skin complaints. The fermented fruit juice is the most widely used modern preparation, now studied for antioxidant, anti-inflammatory, immunomodulatory and metabolic effects supporting several of these traditional uses.[1, 6]
Preparations
Flowering-top extract standardised to hypericin and/or hyperforin content, taken as tablets or capsules; the best-studied clinical form for mood support.
Dosage
Clinical trials for mild-to-moderate depression commonly use around 300 mg of standardised extract three times daily (900 mg/day total); given extensive drug interactions, use should be discussed with a healthcare provider, especially alongside other medicines. Educational reference only, not a prescription.
Commercial noni juice is typically taken in modest daily amounts (a few tablespoons); given rare reports of hepatotoxicity with excessive or prolonged intake, avoid high doses, especially with pre-existing liver disease. Educational reference only, not a prescription.

Pairings
St John's wort raises serotonin activity and can cause serotonin syndrome when combined with other serotonin-boosting agents; pairing it with another mood-active, serotonergic herb such as saffron may add to this risk.[30]
St John's wort is a strong enzyme inducer and increases serotonin activity; combining it with another antidepressant-type herb such as rhodiola may add to serotonergic effects and unpredictably change how each is handled by the body.[30]
St John's wort speeds up the breakdown of many substances and also raises serotonin activity; pairing it with a sedative herb such as valerian may add to drowsiness and can unpredictably change how each is handled by the body.[30, 31]
St John's wort is a strong enzyme inducer and kava is a liver-metabolised sedative; combining them may add to central-nervous-system effects and alter how kava is processed, so combined use warrants caution.[30, 31]
