An estimated 50% of the Australian population take or have taken a Complementary Medicine in the last 12 months. Despite the prevalent use, there is limited knowledge amongst health care professionals, regulatory bodies and the general public regarding the efficacy and safety of many of these medicines. Joanna is involved in a number of projects that aim to contribute towards education in, and quality use of Complementary Medicine. Joanna's' own PhD work investigated the role of probiotics in altering the intestinal microbiota, symptoms and quality of life in individuals with Coeliac disease.
