[YEA] Something that really helps get rid of the flu or a cold is fasting. When you feel the beginning stages of a cold, if you stop eating for a just a day you will often stop it dead in it's tracks. Drinking juice throughout the day instead of eating is another good alternative if you feel you need to get some calories in. Orange juice, preferably freshly squeezed, green juices (made by juicing fresh veggies like celery, broccoli, spinach, kale, etc. ), and other fruit juices like apple juice or mango juice are great to drink for a day or two of fasting.
If you'll be purchasing them, make sure the juices are not from concentrate and are not juice cocktails. Since I use natural remedies during colds, like cayenne pepper or grapefruit seed extract, I've had no problem taking them while fasting or juice fasting but I'm not sure if taking prescription medicines on an empty stomach is a good idea. I've taken the general over the counter stuff like tylenol with no problem, though, I still keep the dose low and don't take it as often as I would if I were eating. Also, if you've got a full blown cold already, you will likely have to fast 2-3 days to get rid of it, maybe more. If you get the chance to stop it early, usually one day will be enough.
