A Thorough Understanding of Herbs Is Critical to Patient Safety

A thorough understanding of herbs is critical to patient safety. An example is the use of cinnamon to treat type II diabetes. It is important the patient uses Ceylon cinnamon, as the commercially available cassia cinnamon contains:

A) Coumadin, which may lead to bleeding problems
B) Coumarin, which can cause liver and kidney damage
C) Cinnamic aldehyde, which is toxic to the kidney
D) Cinnamate eugenol, which is toxic to the liver
