common complications of conventional treatment procedures. Nature is a marvelous source of phytoconstituents
with incredible varieties of biological activities. By tradition, medicinal plants have been utilized for the treatment of
countless infectious diseases worldwide, some of which contain a broad spectrum of activities. Modern drug discovery and development techniques ofer highly efcient separation techniques, inauguration of vector-based schemes
where the original infectious virus is cloned to the non-infectious one for antiviral screening targets. The objective of
the review was to gather available data on 20 both cultivated and native plants of Asia giving antiviral activities and
