Some believe that effective communication between doctor and patient is a core clinical skill that should be taught as rigorously as other medical sciences are taught. Underlying this belief is a growing body of research and development of guidelines acknowledging that physicians need not be born with excellent communication skills but can learn as they practice various other aspects of medicine.
Essiac and Flor Essence are herbal tea mixtures that are sold worldwide as health tonics or herbal dietary supplements (see Question 1).
Essiac was first promoted as a cancer treatment in the 1920s. Flor Essence was created a number of years later (see Question 2).
Supporters of Essiac and Flor Essence say that these products make the immune system stronger, have anti-inflammatory effects, and show anticancer activity (see Question 3).
Laboratory, animal, and clinical (human) studies...
Clinicians specializing in cancer acknowledge that insufficient training in communication and management skills is a major factor contributing to their stress, lack of job satisfaction, and emotional burnout.[3,4] Unfortunately, few oncologists or nurses have received adequate formal education in communication skills using methods likely to promote change, confidence, and competence.[3,4] On the other hand, good physician-patient communication is associated with adherence to drug regimens and diets, pain control, resolution of physical and functional symptoms, control of blood sugar and hypertension, and good psychological functioning of patients.[3,4]
Most (80%) patient-physician communication studies involve primary care physicians (i.e., family medicine physicians, general internists, or pediatricians). However, approximately 20% of studies in one review  used cancer providers, revealing a trend of inadequate training in patient communication for oncologists and other health professionals who deal with cancer patients, particularly with respect to breaking bad news and handling strong, emotionally charged interview contexts.[5,6]
One group of authors believes there are four tasks in teaching effective practitioner–cancer patient communication:
Defining and distributing a comprehensive, evidenced-based curriculum.
Recruiting faculty and/or local practitioners who embrace this curriculum and employ it in practice.
Anchoring the curriculum in evidence-supported behaviors to promote effective interventions and focus clinical controversies on the spectrum of naturally occurring communication styles that arise when working with patients.
Employing longitudinal reinforcement.
Given a well-developed and broadly accepted curriculum, the next step in establishing a successful communication program is to create surroundings that maximize the opportunity to learn, practice, and internalize the curriculum. Longitudinal learning programs that utilize a cohesive faculty result in more meaningful incorporation of curricular elements into the practice styles of learners.
