Assessing the Mechanisms and Impact of a Novel Cannabinoid Product for Gynecologic Pain

Recruiting now · Phase 1/Phase 2 · Has a placebo group

Conditions studied: Endometriosis, Adenomyosis, Chronic Pelvic Inflammatory Disease

In brief

Despite recent increases in both medical and recreational cannabis use in the United States and globally, little research has been conducted to determine the potential applications for womens health. A variety of medical cannabis and hemp-derived products on the marketplace claim to hold efficacy for many womens health-related conditions, including gynecologic pain. This 7-day study of individuals living with endometriosis, adenomyosis, or chronic pelvic inflammatory disease (PID), will identify specific targets and mechanisms underlying the potential impact of a hemp-derived, full-spectrum, high-CBD product in individuals with gynecologic pain.
