Get some dry chamomile flowers, put it in boiling water for couple minutes and breath the steam! Best way to do it: take the pan off the stove, cover your head with a towel so the steam doesn't escape and breath it through your nose and mouth. You can even keep your eyes open.
It is the best healing for flu, excellent for the skin and makes you feel fresh like morning-dew:)
No kidding, 3 times 10 minutes a day when you are sick, and the flu is gone like money from your pocket which you spend for medications. Get well people!
