Not much you can do for a head cold, other than wait 7 days! LOL! Of course, that's what I'll tell me patients.
Some people swear by Echinacea, although every scientific study that's ever been carried out on the stuff shows its ineffective.
Might head up to the store and get you some Sudafed to keep you decongested. Remember, you have to get it from behind the counter now.
Go to a health food store and they can sell you all kinds of snake oils!
They have a Sudafed on the shelf at Wal-Mart that has Pseudephedrine and Guaifenesen (helps the flow of secretions) mixed. It's in a gel cap.
