The active component in cannabis, cannabidiol (CBD), was first isolated from the hemp plant in 1940. Chronic pain, inflammation, migraines, depression, and anxiety have long been treated with CBD. The fundamental mechanisms of CBD’s effects on periodontal inflammation have yet to be fully understood. The amino sulfonic acid taurine is a substance that naturally exists in the body and is an inhibitory modulator of inflammation. This study examined the effects of CBD, taurine, and their combination on inflammatory cytokines and periodontitis in vivo. To assess the expression of inflammatory markers of iNOS, COX-2, TNF-α, and IL-1β, as well as TRAP count and resorbed pit areas, CBD and taurine were applied to RAW264.7 cells. The following groups of 45 Sprague-Dawley rats each were created: control (healthy), vehicle (induced periodontitis), low- and high-dose-CBD with taurine which were each treated for an additional 21 days. Rat teeth were obtained and subjected to histomorphometric studies.The combination of the two significantly decreased the expression of inflammatory markers TNF-α and IL-1β and the amount of TRAP+ cells and resorbed pit areas. Among rats with P. gingivalis-induced periodontitis, the alveolar bone resorption levels, periodontal pocket depth, and distance between cementoenamel junction (CEJ) and alveolar bone crest (ABC) were significantly reduced after treatment with CBD and taurine, suggesting that combining CBD with taurine could be a novel therapeutic agent against periodontal disease.

Osteoporosis is caused by an imbalance of osteoclasts and osteoblasts, and the major treatment technique for treating osteoporosis is to reduce the activity of osteoclastic bone resorption. Limonium tetragonum (LT) is a medicinal plant that contains bioactive molecules with anti-inflammatory and anti-cancer properties. Its effects on osteoclastogenesis, however, remain unclear.Limonium tetragonum extract (LTE) was examined for its inhibitory effect on osteoclastogenesis by TRAP and pit formation assay. As a result, LTE also significantly reduced TRAP formation, the capability to resorb calcium phosphate-coated plates, and F-actin ring formation.LTE reduced RANKL-induced activation of the MAPKs ERK, JNK, and p38 and the production of the transcription factors c-Fos and NFATc1 required for osteoclastogenesis. LTE also reduced the expression of osteoclastogenesis-related genes such as matrix metalloproteinase-9, tartrate-resistant acid phosphatase, and receptor activator of NF-κB. These findings suggest that LTE might be a promising treatment option for bone disorders caused by aberrant osteoclast production and function.
