I’ve been reading a lot about extract of Elderberry. Prevention magazine seems to suggest that it can be helpful with reducing the time that you are sick. I’ve tried it (at the very first sign of a cold) and so far have been able to knock it out. I haven’t been sick in 4 or 5 years (whereas everyone around me gets sick often).

You should also make sure that you wash your hands thoroughly before you touch any food (and afterwards, especially if you have handled any raw meat). And try not to touch your mouth, nose or eyes or ears with your hands. If you have to blow your nose, use disposable tissues, not hankies, and wash your hands (or use hand sanitzer) after every single time you blow your nose or cough. Try not to cough into your hand, cough into your elbow (less likely to rub your elbow on your face). Of course, wash your hands after you use the restroom.
Keep the doorknobs, fridge and microwave handles, toilet handle and all faucets wiped down before and after you touch them (with antibacterial wipes). And wipe down the counter before and after you prepare your food. Throw out your current toothbrush and get yourself a brand new one.
Drink lots of warm liquids, but try to avoid dairy products, which seem to make you produce more mucous. Drink chicken soup (and add onions and garlic), teas of all sorts (decaf so you won’t stay awake), clear mushroom and vegetable and ginger broth and add a tiny bit of black and/or cayenne pepper which will help to open your nasal passges and helps to numb a sore throat. Avoid citrus juices, as they will actually make your throat sting.
If your throat is hurting, extract of echinachea, although the studies have recently indicated that they are not sure if it helps to reduce the time you are sick, will still have a nice numbing effect on the sore throat right after you swallow it. And you can also gargle several times a day with warm salt water.
If you are feeling achy, a nice hot bath can relieve a little of the pain, just make sure you get dried off and into warm dry clothes and dry your hair immediately.
Make sure you launder all of your sheets and blankets and bed covers right after you are feeling better.
