I suggest everyone keep this product at home, and take at the FIRST signs of flu. 
 
If I feel chilled and achey, I start taking Oscillococcinum under the tongue every hour. My other acute flu remedies include high doses of Vitamin A and D, Host Defense Mycoimmunity, bottomless cups of ginger/turmeric tea, and a hot bath or sauna. This combination works extremely well at stopping the flu in its tracks.
