The following classification of drugs included in the list of useful remedies according to their therapeutic use has been adapted from the text-book on pharmacology and therapeutics by Arthur R. Cushny. This index serves to indicate the comprehensiveness of the list and should assist in suggesting to practitioners and teachers possible additions and deletions that might be made so that the list will include all of the fairly well-established remedies that are really of use.

For ready reference the titles used are those under which the drug or preparation has been included and described in the list of useful remedies.
