When ever I have a cold I have a number of remedies I use.
In Scotland we have a thing called a hot toddy which is basically whiskey, cloves, honey and lemon made into a tea.
However, my other remedy (and this is the disgusting one) I have used and it works... is blend some garlic cloves and water into a blender. Then gulp down some of the brew at night. I normally just try to drink the whole thing. I don't really bother with measurements, Just play about till you find something that works for you. It's the garlic your eating, the water just helps it go own. Plus it's broken up and therefore absorbed into the body quicker and easier.
I also do the same as a mosquito repellent. Blend the garlic and water together and pour through a siv. The pulp I place in plant pots on my pation and the water garlic solution I place in a squeezy bottle and go around spraying my windows and door frames. All blood eating creatures hate garlic.
You can also use Listerine which surprisingly mosqutios hate for some reason. I use a combination of the two.
