Here at Mayernik Kitchen, we make our tinctures with both fresh and dried herbs as an alcohol extraction. Alcohol is an excellent solvent for most herbal constituents and is one of the easiest ways to ingest your herbs. We allow our tinctures to extract for 6-8 weeks before staining and bottling. Alcohol preparations have a long shelf life, so they can be stored for years (in a cool, dark place) and in most cases, they will not loose potency.
