Cannabis Extracts Reduced Gut Inflammation Better Than Pure THC or CBD Alone in Mice

Both pure cannabinoids and cannabis extracts inhibited macrophage nitric oxide and pro-inflammatory cytokine release and reduced expression of cell surface inflammatory markers in vitro. In the colitis mouse model, treatments improved clinical scores and reduced macrophage infiltration in the colon. Cannabis extracts showed higher activity compared to pure cannabinoids, suggesting additional plant compounds contribute to the therapeutic effect.

In vitro experiments with macrophages from young and aged C57BL/6 mice activated with LPS and IFN-gamma, treated with pure THC, pure CBD, or cannabis extracts. In vivo murine colitis model assessed clinical scores, colon macrophage infiltration, and inflammatory cytokines in blood.

This study provides laboratory evidence that whole cannabis extracts may work better than isolated cannabinoids for gut inflammation, supporting the idea that other compounds in the plant contribute to therapeutic effects. It also shows that THC and CBD have distinct immune profiles.

Inflammatory bowel disease affects millions worldwide, and current treatments have significant side effects. If whole-plant cannabis preparations prove more effective than isolated compounds, it could influence how medical cannabis products are formulated for gut conditions.

Animal study with in vitro components; results may not translate to human IBD. Specific extract compositions and doses were not fully detailed. The colitis model does not perfectly replicate human Crohn's disease or ulcerative colitis.
