T.J. Lyle was Wm Cook's protege in the late 1800s, and carried on on the faculty of the institute teaching materia medica after his passing.
I admire him, because when it came time for him to write "his" book, instead of posing and posturing as a know it all, he interviewed the elders of the profession in the Chicago and Indianapolis schools for their best formulas and included them interspersed with the materia medica, and captured the snapshot of the formulation strategies of this profession at it peak here in the States.
The book ended up being immensely influential, first in the 1920: Dr Herbert Nowell in Canada was lamenting the passing of teaching of physician level herbalism, and he put together his Dominion Herbal College Correspondence course, which is still offered in a morphed form today, but my main teacher Cascade Anderson Geller and a bunch of the California herbalists back in the 1980s took that course.
I was reading through this course in the NCNM library one day, about the same time that I had acquired the Lyle Materia Medica, and thought part of it looked really familiar. It turns out Nowell wrote whole sections of his course with Lyle open on the desk beside it, he followed the structure and order of paragraphs, and even included exact formulas from Lyle. He did not plagiarize but paraphrased, although he kept the sequence and content of paragraphs and herbs.
Another way this influenced contemporary herbalism in North America is that the famous Dr Christopher took the Dominion College Course, and rather unapologetically put whole sections of it into his books.
The other influence is that the British Herbalists Association revised and edited the original Lyle, cut out almost 2/3 of the original, and released a limited materia medica version of it during WWII era. They cut the total pages from 666 to 238, in the PDF files.
So this original is a true "missing link" historical volume connecting 1898 Physiomedicalism to contemporary British and North American herbalism.
It has everything in alphabetical order, you will find electrotherapeutics between Echinacea and Elletaria, and dietetics between Diervilla and Dioscorea and hydrotherapy (Aqua) between Apocynum and Aralia.
Physio-Medical Therapeutics, 1897, was written by T.J. Lyle M. D.
