Structure and properties
Immunostimulants do not have a uniform chemical structure.
Effects
Immunostimulants have immunostimulant properties, meaning that they are thought to promote immune system activity and thus reduce susceptibility to infectious diseases. Their efficacy is controversial in the scientific literature. It must also be noted that the immune system is partly responsible for disease symptoms. Therefore, “strengthening” it is not desirable in every case. The individual success of therapy is also difficult to assess. Since they are usually well tolerated, a therapy trial is possible.
