TheraFlu is bad for you. I don't remember why.
I just take a cup of hot herbal tea, and mix in honey (tablespoon), hot sauce (a few drops), salt (pinch), and lemon juice (teaspoon), then drink it and breathe in the vapors. It is foul, but effective. If there is also a fever/headache, I take a Feverfew tablet. For runny nose, liquid Mucinex. Then bed, lots of moist heat, and about 4 hours later, all better.
