Take this amount every few hours as soon as you feel a cold or other illness coming on. After initially trying it with only one 'dose' and seeing the immediate effects, I now mix up a small bowl full of honey and cinnamon and spoon it into hot drinks or dip fruit into it all day long.
I find that with young children it's easy to just treat the whole family with this simple yummy remedy upon the first sign of a sniffle from anyone.
