The “flu” and “flu-like symptoms” (including the common “cold”) is literally just the body’s natural/healthy detoxification process. Loss of appetite, fever, fatigue and mucous production are all there so your body can rest and detoxify itself naturally. In other words, anything you can do to assist this process is beneficial. The body has to remove waste and when it gets clogged, it tells you to stop eating, stay in bed, sweat it out. The body is an amazing thing, it knows exactly what it has to do!
