Herbalist and hydrotherapist who re-discovered the healing properties of a number of simple plants for the treatment of major diseases of the day (gout, arthritis, etc) when 19th century German pharmacy was beginning to extract and use concentrated alkaloids, glycosides (Foxglove) of plants. He insisted on use of the whole plant. Clinical experience of this tireless investigator led to the belief that Horsetail (Equisetum) arrests the growth of tumours, and where conditions are favourable may dissolve them. See: WHOLE PLANT.
