Periodontitis is a chronic inflammatory disease and gums pull away from the teeth and form spaces. The main goal of treatment is to control the infection and anti-inflammation. Eucommia ulmoides Oliv. Bark (EU) is a traditional Korean herbal used for the treatment of arthritis and hypertension. In the present study, we investigated the anti-inflammatory properties of EU in Porphyromonas gingivalis-LPS (LPS-PG) induced YD-38 epithelial cells. We observed significant inhibition of nitric oxide (NO) production and the expression of interleukin-8 (IL-8), interleukin-6 (IL-6), tumor necrosis factor alpha ($TNF-{\alpha}$), cyclooxygenase-2 (COX-2) in LPS-PG-induced YD-38 cells. These results support that EU has an anti-inflammatory effects for the treatment of periodontitis.
