Botanical Overview
Agastache rugosa belongs to the Lamiaceae family. While not among the most extensively documented medicinal plants, this species has recorded uses that warrant attention from researchers and practitioners. The mint family (Lamiaceae) includes aromatic herbs and shrubs with square stems, opposite leaves, and two-lipped flowers. Many species produce essential oils in glandular trichomes on their leaves and stems. This family is one of the most important sources of culinary and medicinal herbs worldwide.
