This edition (previous in 1996) guides the Oriental medical practitioner toward finding appropriate herbal prescriptions once an Oriental medical differential diagnosis or pattern discrimination is established. It assists practitioners in custom-tailoring those formulas to their patients' needs by providing single herb modifications sorted by patterns of disharmony. The book also covers preparation procedures and a four-way herb name cross-reference. Appendices guide the reader to what's needed to set up a pharmacy along with a list of suppliers for Chinese herbs. Annotation c. Book News, Inc., Portland, OR (booknews.com)
