Brief Summary

This study consists of a randomized, double-blind, placebo-controlled crossover trial with open label extension evaluating a topical natural health cream containing ß-caryophyllene alone and in combination with 0.025% capsicum oleoresin against placebo. At the end of the randomized controlled phase of the trial all participants will be given open-label combination cream to be administered over the subsequent 3 weeks. Primary Endpoint: Evaluation of improvement in pain interference as measured by the BPI in individuals who are experiencing pain due to osteoarthritis of the knee. Secondary Endpoints: Secondary endpoints are: Confirmation of safety of the topical cream when used daily over 10 weeks. Further evaluation will include overall patient satisfaction with the products tested.
