- Organon of Medical Arts by Samuel Hahnemann, ed Wenda Brewster O'Reilly (external link)

- Samuel Hahnemann was the man who brought ancient principles of healing together with innovative discoveries to formulate the healing art and science now known as homeopathy. His best-known work, the Organon was first published in 1810 and sets out the principles for healing with homeopathy. This modern translation by Wenda Brewster O’Reilly brings this sometimes difficult text beautifully to life.
