What is probiotic therapy? What is prebiotic therapy? What does alternative medicine mean? What are the pros of each kind of therapy? Why do they work? What are the cons of each kind of therapy? Why don't they work? Discuss at least one current therapy in use or being investigated for each type (probiotic, prebiotic, alternative medicine). Provide your thoughts about the use of these types of therapies (picking a specific bacterium) versus treatment with antibiotics, etc.
