Engystol® Injection Solution is a homeopathic drug indicated for the support of the immune system to reduce severity and duration of symptoms in viral infections, particularly in the early stages of colds and influenza-like illnesses. The exact mechanism of action of Engystol® is still under investigation.
In vitro tests have demonstrated that Engystol® stimulates the phagocytic activity of human granulocytes by up to 33.5%.1
Further in vitro studies have demonstrated that Engystol® significantly increases the expression of interferon-γ producing T-lymphocytes. Therefore, it appears likely that there is an immunological stimulation caused by Engystol®, that is mediated by the activation of T-lymphocytes. Using Engystol®, therefore, enhanced the Th1 response, this being an antiviral pathway in the body.2
Other studies have indicated that Engystol® is associated with a stimulation of the immune system in terms of granulocyte function and improved humoral response.3, 4
