Herbal products have gained considerable interest among the pharmaceutical companies and consumers due to
the minimal side effects associated with them. The bioflavanoids present in these products are the key players in modulating
their effects. Several therapeutic effects have been attributed to the bioflavanoids present in green tea and turmeric.
Antimicrobial activity is one among the spectrum of activities they exhibit. Curcumin and catechins, the principle components
of turmeric and green tea respectively have virucidal and virustatic actions. An antimicrobial composition consisting
of extracts from green tea and turmeric have shown to be highly potent against various microbes, especially viruses. In the
present review, we have discussed the patents and the antiviral effects of curcumin and catechins. The antimalarial effect
of curcumin has also been discussed.
