This past weekend I was sick as a dog--couldn't move, eat, or do anything much besides cough and attempt to breathe regularly. In addition to Sudafed (the old school kind that you have to show ID for and get from the pharmacist because people make meth out of it), I relied on my other favorite remedy, Fresh's Sake Bath.
While I have no idea if any of the claims are true, supposedly the ingredients (which include 35% sake as well as ginger and fruit) increase your circulation and body temperature, thus allowing you to sweat out toxins. It also contains pine extract, which is good for clearing out your sinuses. At the bare minimum, it smells great and makes for a relaxing bath when you feel like death warmed over and you only have enough energy for turning on the faucet. Plus, I support any beauty product made out of alcohol.
