In vitro experiments found that TECA can inhibit the inflammatory response induced by LPS, and can effectively reduce the level of IgE and the release of inflammatory cytokines (IgE can induce the activation of mast cells and release a variety of allergic mediators, such as cytokines, histamine, etc.). Studies have shown that TECA can inactivate macrophages in the skin, thereby reducing skin inflammation and atopic responses [3].
