The recommended dosage for adults is typically 1-2 grams of dried plant per cup of tea, taken up to three times daily, while children should only use it under medical supervision, with a lower dosage.

Due to limited research, use should be conservative, with short durations and frequent monitoring to ensure safety and efficacy.

Safety, Side Effects and Contraindications

However, it may cause side effects such as gastrointestinal discomfort, including nausea and vomiting, as well as dizziness and fatigue in some individuals. Petasites hybridus may interact with certain medications, particularly those affecting the respiratory system or the central nervous system, and should be used cautiously with other herbs or drugs that have similar effects. It is contraindicated during pregnancy and breastfeeding due to limited safety data and potential risks to the fetus or infant.

For safe use, it is recommended to consult a healthcare professional before use, follow recommended dosages, and monitor for any adverse reactions, especially in individuals with pre-existing chronic illnesses.

Growing, Harvesting and Storage

Petasites hybridus grows in moist, well-drained soils in partially shaded to fully shaded environments, typically in temperate regions with cool, humid climates.

It thrives in loamy or clay-rich soils with high organic matter content and requires consistent moisture without waterlogging. Regular watering is essential, especially during dry periods, and mulching helps retain soil moisture and suppress weeds. For optimal growth, it should be planted in early spring, and regular monitoring for pests and diseases is recommended to ensure healthy development. Harvesting is best done in late summer to early autumn when the leaves are fully developed but before the plant begins to die back, using a sharp knife to cut the leaves at the base.

After harvesting, the leaves should be dried in a shaded, well-ventilated area to preserve their potency, then stored in airtight containers in a cool, dark place to maintain their medicinal properties.
