Hi, The last few days I have had a pretty bad cold. Runny nose, sore throat ect. And have recently just had a cough. This morning I woke up and felt really sick in the stomach and ended up vomiting out bile, nothing else. I have stopped with the vomiting now. But I was just curious, does lemon juice kill bacteria? I was just wanting to know if it would help my situation or not? Thanks, Hayley
