willow bark has caffeineYep, Yaupon Holley. The only tree in N.America with caffiene in it (supposedly). Razor had it somewhat right. The old ones dranked it before an important event,like ball games, war, etc. NDN's traded that plant all over the country. Roast the leaves then brew. Taste like coffee/tea mixed. It is a diuretic. Wood is good for crafts/fires. Chew leaves for caffiene withdrawal headaches. One of those berries will make you take a trip & never leave the farm it digested
I know the Creek tribes from alabama used it....So probably the Choctaw,Cherokee and Chicksaw also.what tribes used them like that, do you know?
