It can be prepared as a tea by steeping dried leaves in hot water, or as a decoction by boiling the plant material for a longer period. For topical use, a diluted essential oil or powdered form can be applied directly to the skin.

Safety, Side Effects and Contraindications

Agastache foeniculum can be considered relatively safe when used in moderate amounts for short-term purposes, although it may cause mild side effects such as gastrointestinal discomfort, nausea, or allergic reactions in some individuals.

It is generally well-tolerated, but excessive consumption may lead to more severe symptoms like dry mouth, dizziness, or increased heart rate. There is limited research on its interactions with medications, but it may interfere with blood thinners or antidiabetic drugs due to its potential effects on blood clotting and glucose metabolism. Pregnant and breastfeeding women should avoid agastache foeniculum due to insufficient evidence on its safety during these periods, and individuals with chronic illnesses should consult a healthcare provider before use.

To ensure safe use, it is recommended to start with small doses, avoid long-term use, and consult a qualified healthcare professional, especially if taking other medications or having pre-existing health conditions.

Growing, Harvesting and Storage

Agastache foeniculum grows in well-drained soil with a pH between 6.0 and 7.5, thriving in full sun to partial shade and requiring moderate water during the growing season.

It is a hardy perennial that benefits from regular watering during dry periods, but it should not be overwatered to avoid root rot. To ensure optimal growth, it should be planted in early spring after the last frost, and regular weeding and mulching can help suppress weeds and retain soil moisture. The best time to harvest agastache foeniculum is in late summer to early autumn when the leaves and flowers are most aromatic and potent, using clean pruning shears to cut the stems just above a node.

After harvesting, the plant material should be dried in a cool, dark, and well-ventilated area to preserve its medicinal properties, then stored in airtight containers in a cool, dry place or refrigerated to extend shelf life.
