It is a long running product by vicks. it is an ointment type of thing which is used externally against cold and flu int specially chest nose and forehead sections of the body. personally I dont like it. whenever I used it in my forehead, it caused burning sensation in my eyes.
I think it does not work a little bit against flu. Only it reduces the allergic problems of such during common cold. I will say anybody to use a better ointment
