Airborne diseases are becoming a great threat to human kind due to its highly infectious mode of transmission. Medicinal plants have been traditionally used to cure many pathogenic diseases including diseases caused by viruses. Plants contain bioactive compounds which are capable of inhibiting the growth of most pathogens and also show antiviral activity. Since these plants are of natural origin, these biochemicals possess minimum toxicity and their possibility of causing allergies to an individual is also low. Biochemicals showing antiviral properties have been found in various parts of the plants like roots, stem, leaves, flowers, etc. This review focuses on the antiviral properties of plants against air borne viruses - Influenza, Rhino virus, SARS, HSV and RSV, which mainly affect the respiratory tract.
