[Comparison of the in vitro activities of ammonium humate and of enzymically oxidized chlorogenic and caffeic acids against type 1 and type 2 human herpes virus (author's transl)].

Ammonium humate (prepared from marsh water humic acids) as well as enzymically oxidized diphenolic compounds such as the oxidation products of chlorogenic and caffeic acids have strong antiviral activities in vitro. The effective concentrations lie considerably outside the cytotoxic range of the compounds mentioned.
