Is there anything out there for the common cold?

I am male so, obviously, having a Cold has brought me to my Knees :-)

Apart from Whisky, Hot Water and Sugar (Tried it, didn't work, but I felt pretty good) or sticking a piece of seaweed up me bum, is there anything out there that 'Does what it says on the packet'?

Answers that are seen as 'Old Wives Tales' are more than welcome.
You clearly have man-flu, an unpleasant variant of the Influenza virus as a result of which you must take to your bed immediately, groan loudly at random intervals, adopt a puppy dog expression, expect the female of the house (who might have a bit of a cold as opposed to any variation of flu through which she must stop whinging and get on with it) to pander to your every whim.

Joking aside, take high dose vitamin c, garlic capsules and echinacea to boost the immune system. Drink plenty of clear fluids (NOT alcohol, you'll just get a hangover on top of your cold), a Lemsip or other similar product and some olbas oil or vicks nasal spray for a blocked nose.
