I decided to try Sinu-Rite for her sinus infection and AmazPet for her asthma. I figured Respo-K only works for minor cold without infection. Distributor in Hong Kong does not carry Sinu-Rite and AmazaPet, so my friend sent them to me from San Francisco. After three tablets of Sinu-Rite today(one tablet five times daily), Minna actually stopped sneezing, I am not sure it actually worked within one day or just coincident. I'll definitely have another update about Sinu-Rite and AmazPet.
