Natural Remedies for Treating a Cold

I normally take a whole bunch of supplements and remedies to keep my immune system strong so that colds are kept at bay.  I have recently run out of a few things due to some financial commitments and wow it’s made a huge difference, and not in a good way. I’ve actually had 3 colds in the space of 6 weeks! I thought I would look into the natural remedies one can take when you do get a cold.
