Weeds used in medicine

A practical handbook for farmers and collectors describing how common field weeds may be gathered, prepared, and cured for use as crude medicinal drugs. It explains proper seasons and techniques for digging roots and harvesting barks, leaves, flowers, and seeds; cleaning, drying, slicing, and storage methods; and precautions to prevent mold, contamination, and misidentification. The main portion offers concise botanical descriptions, uses, and preparation tips for many familiar species—such as burdock, dandelion, docks, couch grass, pokeweed, foxglove, mullein, lobelia, tansy, yarrow, jimson weed, poison hemlock, and mustards—supported by illustrations and practical advice on handling and marketing small lots.
