Hypericum Perforatum (Homeopathic)

Hypericum perforatum (St. John's Wort) in homeopathic preparation is primarily valued for its bioactive phytochemical profile rather than macronutrient content, as it is consumed in very small doses. Key bioactive compounds include: **Hypericin** (0.05–0.3% in crude herb; naphthodianthrone class) — the primary marker compound responsible for photosensitizing and antidepressant activity; bioavailability is moderate orally with a half-life of approximately 24–48 hours. **Hyperforin** (2–5% in standardized extracts of the crude herb; phloroglucinol derivative) — considered the principal antidepressant constituent via inhibition of serotonin, dopamine, norepinephrine, GABA, and glutamate reuptake; highly lipophilic but unstable and light-sensitive, reducing bioavailability unless stabilized. **Flavonoids** including rutin (up to 1.6%), hyperoside (0.5–2%), isoquercitrin, and quercetin — contributing antioxidant and anti-inflammatory effects; bioavailability of quercetin glycosides is moderate (~20–30% absorption). **Procyanidins (oligomeric proanthocyanidins):** approximately 2–4% — support vascular health and antioxidant defense. **Pseudohypericin:** approximately 0.2–0.5% — structurally related to hypericin with similar but milder photodynamic and antiviral activity. **Xanthones** including 1,3,6,7-tetrahydroxyxanthone — minor constituent with MAO-inhibiting properties. **Essential oils** (0.1–0.3%) containing α-pinene, myrcene, and caryophyllene — contributing mild anxiolytic effects. **Tannins:** 6–15% (catechin-type) — astringent properties; may reduce absorption of co-administered nutrients/medications. **Phenolic acids:** chlorogenic acid and caffeic acid in trace amounts — antioxidant contributors. **Vitamins and minerals:** Not a significant dietary source; trace amounts of vitamin C, vitamin A precursors (carotenoids), and minerals (potassium, calcium, iron, zinc) are present in whole-herb preparations but are negligible at homeopathic dosing. **Macronutrients:** Per typical dose, essentially zero caloric, protein, fat, or carbohydrate contribution. **Homeopathic potency note:** In homeopathic dilutions (typically 6C, 12C, 30C, or 200C), the concentration of original bioactive molecules decreases exponentially with each centesimal dilution; at potencies of 12C and above (dilution beyond Avogadro's number, ~6.022 × 10²³), measurable molecular concentrations of hypericin, hyperforin, and other compounds approach zero, and the mechanism of action is attributed to the homeopathic principle of 'potentization' rather than direct biochemical activity. Standardized herbal (non-homeopathic) extracts are typically dosed at 300 mg three times daily, standardized to 0.3% hypericin and/or 2–5% hyperforin, to achieve clinically relevant bioactive compound exposure.
