Botanical Overview
Leopard’s-Bane (Arnica montana) is a flowering plant in the Asteraceae family. Traditional medicine systems have documented several valuable applications for this species, supported by its observed therapeutic effects. The daisy family (Asteraceae) is one of the largest plant families, characterized by composite flower heads (capitula) that contain many small florets surrounded by bracts. Plants range from tiny alpine herbs to large tropical trees. The family includes many medicinally important species with bitter compounds and essential oils.

Respiratory conditions.
- Expectorant
Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
