Tried a mineral remedy like Arsenicum and it hasn't quite done the biz? This reference may help you find a plant analogue, since it lists the mineral content of 100 plants, sorted in order of degree; for instance, Humulus, (Hops), is highest in copper and selenium. Plants are described by their Latin, English, German, French and Dutch names. At the back of the book each element has its corresponding plants listed alphabetically, together with the mineral content of each. Although quite a high-tech read, it will appeal to those already familiar with Scholten's system, already written up in "Homoeopathy and the Elements" and "Homoeopathy and the Minerals". (See Bk 130 and Bk 124 respectively).
