Table 4 provides a list of ODFs formulated using herbal extracts. From the table, it is evident that solvent casting method is the most preferred method to fabricate herbal ODFs. Zim laboratories limited, a leading Indian company in the domain of oral thin films has published a research article on oral dissolving films of ginger [21]. Visser et al. reported ODFs of five Indonesian medicinal plants extracts namely: Lagerstroemia speciosa, Phyllanthus niruri, Cinnamomum burmannii, Zingiber officinale, and Phaleria macrocarpa [92] were prepared by solvent casting method [95]. Of these plant extracts, Phaleria macrocarpa and Zingiber officinale are associated with antiviral activity [96,97]. Song et al. evaluated antiviral activity of quercetin-7-glucoside isolated from Lagerstroemia speciosa [98]. Sri Wahyuni et al. reported antiviral activity of Phyllanthus niruri, particularly they reported its activity against hepatitis C virus [99].
