The Cowden Support Program utilizes 14 different Nutramedix products including 6 Microbial Defense herbals (3 pairs of herbals) that are taken rotationally. The first pair (Banderol and Samento) were studied in vitro by Eva Sapi, PhD and her group at the University of New Haven, Connecticut and found to eliminate all forms of Borrelia burgdorferi (spirochetes, round-body forms and biofilm forms). In that study, doxycycline antibiotic was not nearly as effective against biofilm and round body forms of Borrelia burgdorferi. Richard Horowitz, MD in New York State has found the Cowden Support Program to be effective in markedly improving the condition of 70-80% of the advanced Lyme Borreliosis patients with co-infections over 4 to 6 months time, even if the patients had previously failed to improve on multiple courses of antibiotics. Dr. Horowitz presented the findings of his use of the Cowden Support Program in a fairly large group of his patients with Lyme Borreliosis & co-infections at the ILADS conference in the fall of 2007. More recently, a 9 month observational study with the Cowden Support Program was conducted by the Borreliose Centrum Augsburg, Germany. Completed in 2012, this study resulted in 80% of patients showing symptomatic improvements (via questionnaire) and 90% of patients showing improvements via lab blood tests.
