I use thyme honey lemon tea. 1 tsp dried thyme, honey and lemon to taste. Steep thyme in 1 cup hot water. I use a tea ball like is used for making loose tea in a pot, add honey and lemon and sip away. I do this three times a day. A cold or flu always settles in my chest and this will break it up. I found this about 4 years ago and have yet to buy any kind of OTC remedy for a cough or congestion.
