Weeds used in medicine
Weeds used in medicine by Alice Henkel is a practical scientific publication (a USDA Farmers’ Bulletin) written in the early 20th century. It outlines how common weeds can be identified, harvested, and prepared for medicinal use, emphasizing proper collection, curing, and basic marketing. The bulletin opens with clear instructions on timing harvests, cleaning and shade-drying roots, leaves, flowers, and seeds, and packing samples for sale. It then profiles a wide range of weeds—from burdock, dandelion, docks, couch grass, and pokeweed to foxglove, mullein, lobelia, tansy, grindelia, boneset, catnip, hoarhound, blessed thistle, yarrow, Canada fleabane, jimson weed, poison hemlock, wormseed, and black and white mustards. Each entry notes common names, habitat and range, plant description, the parts used, when and how to collect and cure them, principal medicinal uses, and typical market prices, with warnings for poisonous species (e.g., foxglove, jimson weed, poison hemlock, lobelia, pokeweed). Throughout, the book encourages farmers to turn weed eradication into modest profit by supplying clean, well-dried crude drugs that meet dealers’ standards.
