The H.E.R.B.A.L. Guide will greatly assist clinicians in counseling patients about use of herbal and dietary supplements and integrating these supplements into the comprehensive clinical management of common conditions. The opening section offers practical advice on the clinician-patient dialogue about supplements. Subsequent chapters discuss key issues regarding labeling, dosing, regulation, interactions and reactions, efficacy, clinical trials, and the role of each member of the health care team in management of supplements. Major sections present case studies of patients with common conditions and quick reference guides to the use of natural medicines in clinical management of specific disorders.
