2. Some of the observations of the old prescribers concerning sequence of remedies bear out the group-relationships of Boyd. There is the croup-group, consisting of Aconite (group I), Spongia (group VI), and Hepar (group X). There is the natural sequence that Hering observed for chronic cases: Sulph. (group VIII), Calc. (group IV), and Lyc. (group V).
3. It is the authors opinion and Phos. will often help a patient when Ars. is better indicated and vice versa. In cases of pneumonia where Phos. has been followed by Ars., he has observed in retrospect that Ars. really was the better remedy at the start. The two do not, however, appear to be inimical.
4. Possibly group VII is related to groups I, VI and X. McCrae suggests that II may be related to IV.
Boyd explains: “The drugs which are in bold face have strong support from clinical administration after Emanometer- selection as being grouped correctly. Where correct grouping of drugs has been obtained, the drug indicated on the Emanometer by matching the patients group and the drug-group tends, in chronic cases, to remain constant and to stand repetition in the chosen potency, provided the original prescription is successful. The action is wide and covers practically the whole symptomatology.
“The drugs in italics have had such a widely ameliorative action in given cases that the grouping is well supported. The remaining drugs have acted well in certain cases but not in sufficient number of cases to advance clinical support of the grouping.”.
