It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by simmering for a longer period, while an infusion involves a gentler extraction method.

For internal use, adults are generally recommended to take 1-2 capsules daily or consume 1-2 cups of tea per day, while children should only use it under medical supervision.

Due to its potency, it is advised to use helichrysum italicum sparingly and for short durations, unless otherwise directed by a healthcare professional.

Safety, Side Effects and Contraindications

Helichrysum italicum can be a beneficial medicinal plant used for its anti-inflammatory, antimicrobial, and antioxidant properties, but it should be used with caution.

While generally considered safe when used in appropriate doses, it may cause mild side effects such as skin irritation, gastrointestinal discomfort, or allergic reactions in some individuals. It may interact with certain medications, including anticoagulants and sedatives, and should not be used concurrently with other herbs that have similar effects, such as chamomile or valerian. Special populations, including pregnant or breastfeeding women and individuals with chronic illnesses, should avoid using helichrysum italicum without consulting a healthcare professional due to potential risks.

To ensure safety, it is recommended to use high-quality, properly prepared products, start with small doses, and discontinue use if adverse effects occur.

Growing, Harvesting and Storage

Helichrysum italicum grows best in well-drained, sandy or loamy soil with a slightly acidic to neutral pH, thriving in full sun to partial shade.

It requires moderate watering, allowing the soil to dry slightly between waterings to prevent root rot. Regular pruning and deadheading encourage continuous blooming and maintain plant health, while mulching helps retain soil moisture and suppress weeds. The best time to harvest is when the flowers are fully open but before they begin to wilt, typically in late summer to early autumn, using sharp scissors to cut the flower heads just above the leaves.

To preserve its potency, the harvested material should be dried in a cool, dark, and well-ventilated area, then stored in airtight glass containers away from light and moisture, ideally in a cool, dry place or refrigerated to extend shelf life.
