"This is a wonderful addition to the field of laboratory medicine.
You need this book if you ever have to answer questions on how
herbal supplements affect clinical laboratory tests." (Doody's, 23
September 2011)

"Summing Up: Recommended. Medical students and clinicians."
(Choice, 1 August 2011)

"Even though Americans rely increasingly on alternative
medicine, herbal and traditional remedies do not undergo the
testing for safety and efficacy as pharmaceutical drugs. In this
book, editors Dasgupta (pathology and laboratory medicine, U. of
Texas Medical School at Houston) and Hammett-Stabler (pathology and
laboratory medicine, U. of North Carolina at Chapel Hill) present a
balanced and comprehensive introduction to herbal supplements,
emphasizing the pharmacological interactions between herbal
supplements and Western pharmaceuticals". (Booknews, 1 June
