Purified root extracts from Echinacea purpurea (L.) MOENCH.,
Echinacea angustifolia D.C. and Echinacea pallida (NUTT.) NUTT.
revealed biological activity in different immunological and
virological test systems. All three plants exhibited different
activity on immunological parameters, such as mitogenic
stimulation, production of immunoglobulin IgM and of certain
cytokines. An antiviral activity versus herpes simplex virus
(HSV-1) and influenza virus (A2) was observed. The extracts under
investigation also showed an indirect antiviral effect via
stimulation of the interferon alpha, beta-production.
