Forms, Preparation and Usage
Hypericum annulatum has a variety of forms available, including fresh plant material, dried tincture, powder, essential oil, and capsule, each offering different methods of preparation and application.
It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by simmering the plant parts for a longer period, while an infusion involves using fresh herbs. For topical use, the essential oil or powdered form can be applied directly to the skin, often diluted with a carrier oil. The recommended dosage for adults is typically 1-2 teaspoons of tea three times daily, while for children, it should be used only under medical supervision and in smaller amounts.
Due to the potential for mild side effects and lack of long-term studies, usage should be conservative, with a duration of no more than two weeks unless advised otherwise by a healthcare professional.
Safety, Side Effects and Contraindications
Hypericum annulatum can be used as a medicinal plant, but it requires careful consideration due to its potential safety concerns.
While it is generally considered safe when used in recommended doses, it may cause side effects such as gastrointestinal discomfort, dizziness, and in rare cases, photosensitivity reactions. It should not be combined with other herbs or medications that affect the central nervous system, particularly antidepressants like SSRIs, as this may increase the risk of serotonin syndrome. Special populations, including pregnant and breastfeeding women, should avoid its use due to insufficient safety data, and individuals with chronic illnesses should consult a healthcare provider before use.
For safe use, it is advisable to follow recommended dosages, monitor for adverse reactions, and consult a qualified healthcare professional, especially if taking other medications or having pre-existing health conditions.
Growing, Harvesting and Storage
Hypericum annulatum grows in well-drained, sandy or loamy soils with a slightly acidic to neutral pH, thriving in full sun to partial shade and requiring regular watering during dry periods.
It benefits from mulching to retain moisture and suppress weeds, and should be pruned annually to encourage bushier growth and prevent overcrowding. The best time to harvest the bright yellow flowers is in late spring to early summer, just as they begin to open, using clean, sharp scissors to cut the flower heads without damaging the plant. After harvesting, the flowers should be dried in a cool, dark, and well-ventilated area to preserve their potency, and stored in airtight containers away from light and moisture to maintain their medicinal properties.
Proper care and timely harvesting ensure the plant's effectiveness for use in herbal remedies and traditional medicine.
