RAVEENDRAN NAIR, Ph.D.1, RICHARD T. CLÈMENT, M.D.,3 and STEVEN J. MELNICK, Ph.D., M.D.2 ABSTRACT Background: The efficacy of homeopathic medicines for maintaining human health and treating disease hasbeen extensively examined in clinical trials. However, there is a paucity of preclinical evaluations of the ef-fects of homeopathic medicinal preparations on cellular signaling pathways relevant to the applications of thesepreparations. Materials and methods: In this study, the immune-modulatory effects of Phase 6 (for the stimulation of thenonspecific defense system) and Flu Terminator® (for influenza and viral diseases) (Be Well HomeopathicsInc. Miami, FL), two homeopathic preparations developed for the purpose, were evaluated in normal humanleukocyte cultures in vitro. Results: Both Phase 6 and Flu Terminator stimulated the production of pro- and anti-inflammatory cytokinesby human leukocytes, although higher doses often produced a weaker response than lower doses. The carriersolvent (20% ethanol) failed to elicit any cytokine synthesis. Conclusions: The results of the in vitro studies suggested that ultralow concentrations of ingredients in Phase6 and Flu Terminator were capable of eliciting a human immune response.
