“Cannabidiol (CBD) is a cannabinoid component from Cannabis sativa that does not induce psychotomimetic effects and possess anti-inflammatory properties.  In the present study we tested the effects of CBD in a periodontitis experimental model in rats. Morphometrical analysis of alveolar bone loss demonstrated that CBD-treated animals presented a decreased alveolar bone loss. These results indicate that CBD may be useful to control bone resorption during progression of experimental periodontitis in rats.” https://www.ncbi.nlm.nih.gov/pubmed/19070683
