Harvesting Instructions

  • Harvest when medicinal properties are at the peak in mid- to late summer on a dry, sunny day
  • Cut the entire aerial part of the plant, leaving about twelve inches at the base for regenerative growth, it is possible to get a second cutting from well-established plants
  • Easy to over-dry and loose medicinal value – hang in bundles upside down in an area protected from the elements with good airflow and check regularly or for small amounts, in a single layer on a drying rack
  • When plants begin to crumble easily, remove foliage and flowers from stems and store in an airtight container (preferably with paper or desiccation packets added to absorb moisture and prevent molding over time)
