I need help! continuous post nasal drip?

A friend of mine has sinus with symptoms like yours and tried a blend of 3 plant extracts. Worked great with him as his sinus eased only after 3 days of use. He is still using it and he told me that he had never felt better - no more pain in his nose, no bad breath and blocked nose. So I checked it out and found out that the 3 plant extracts are actually cinnamon, thyme and clove - popularly used to relief coughs, colds, respiratory infections.
