I have found Ginseng Concentrate an excellent substitute for coffee & tea. Don't know how it will stand as a Paleo item? It comes in a jar and is tar like in substance. You put about 1 - 2 grams into hot water according to taste. It looks just like coffee, has a strong smokey taste, and also, seems to give a little kick, maybe psychological. I am always amazes at how people think they get a big caffeine kick out of Espresso, when it fact it has less caffeine than coffee. The longer roasting of the beans burns out the caffeine. The Ginseng extracts are usually 96% ginseng 4% water and made from 6 year old roots. Bob Martin Webmaster AgeLess Resources http://www.ageless.com
