The 2nd edition of this book by the 19th century British practitioner, a close associate of Clarke & Burnett, who used "arborivital" mother tinctures (prepared from living plants) in practice.

Chiefly Arborivital Treatment with Illustrative Cases.

PREFATORY NOTICE.

I HAVE termed the system proposed by rne for the better investigation of the curative action of plantremedies, Arborivital, from the fact that this curative action is an inherent property of living plants, a truth which has hitherto been entirely unacknowledged by medical scientists.
Whether the existence of such a power was suspected by Hahnemann or not it is impossible for anyone to say, but certain it is that he considered single drops of plant remedies too strong for use when symptomatically related to disease. That these single drops—the unit or arborivital doses—are not too strong for use in malignant diseases, is amply shown in the body of this little work.
In fact, it is not possible to urge any reasonable objection to the use of these doses in suitable cases.
There is, then, obviously, no intention of initiating a new system of medicine; between the idea conveyed by this term and a system for the better prosecution of research into the actions of a limited group of remedial agents upon a defined class of diseases, a very wide distinction must be drawn.
Confessedly the outcome and development of Hahnemann's ideas, my researches have been in no way directed to the furtherance or sustainment of existing systems of medicine.
All I lay claim to is an honest and practical inquiry into the curative actions of certain remedial agents upon what were hitherto supposed to be incurable diseases, and with the results I am proud to admit myself fully satisfied.
My position will perhaps be better understood, even at the risk of subsequent repetition, by a reference to the following letters called forth by an Editorial Article and subsequent correspondence in Invention newspaper :—
