Water, water, water.........are you drinking enough? As hard as I know this is for people to believe, it is the missing ingredient in many, many health issues. We are 70% water and we drink mostly tea, coffee and soda. Tea and coffee are strong diuretics which rob us of what water we do drink. You need 16 ounces of water to counteract the effects of one 8-ounce cup of coffee or tea. I am an herbalist and my clients learn the important value of water in feeling better. It's really that important.
