Eczema

A comparative study into the topical anti-inflammatory activity of cannabinoids (on croton oil-inflamed skin in mice) showed that Δ8THC, Δ9THC and THCV are about half as effective in reducing inflammation as Indometacin (a commonly used Non-steroid anti-inflammatory drug), but approximately 5 times more effective than CBCV and CBD. CBC and CBDV had no appreciable anti-inflammatory activity (Tubaro et al., 2010).
