First published in 1874 and reissued here in its second edition of 1879, this substantial work provides information on the vegetable material medica used by Victorian pharmacists, principally in Britain but also in India. Arranging the entries according to the type of plant from which each drug is derived, Daniel Hanbury (1825–75) and Friedrich August Flückiger (1828–94) give a description of each drug as well as covering its botanical origin and history, including its first medicinal application. They also discuss chemical composition, referring to the investigations of other scientists as well as their own, and comment on microscopic structure. Intending to create a broad reference work rather than an encyclopaedia, the authors chose not to focus on the therapeutic applications of the drugs. In many instances, however, they give some information on how the plant products are used. The appendix provides short biographical and bibliographical notes.
