Emodin is a naturally occurring anthraquinone present in the roots of numerous plants and lichens and an active ingredient of various Chinese herbs. Emodin possesses various biological properties and serves as an anti-bacterial and anti-inflammatory agent. Emodin was studied as a potential anti-cancer agent: e.g., it was shown, that compound inhibits the invasion and migration of colon cancer cells in vitro and in vivo by blocking EMT, which is related with the inhibition of Wnt/β-catenin signaling pathway. Besides, emodin effectively ameliorates asthmatic airway inflammation and alternatively activated macrophages (AAMs) polarization, and thus can be a potential agent for the treatment of asthma. It is known that the Inhibition of AAMs is an alternative therapeutic strategy for treating asthma. Some experiments have revealed that emodin can be a beneficial dietary supplement in prolonging lifespan.
