Eclectic medicine and botanical pharmacognosy
A monumental work of American botanical medicine and the definitive reference for the 'Eclectic' school of medicine. The 1898 revision by Felter and Lloyd represents the peak of 19th-century clinical herbalism. It provides exhaustive data on the botanical description, history, chemical constituents, and therapeutic actions of hundreds of medicinal plants, with a strong focus on North American species. John Uri Lloyd's contributions on plant chemistry are considered foundational to modern pharmacognosy.
