Herbal Wisdom by Brittany Wood Nickerson Illustrations by Chelsea Granger Water-based medicines, such as teas and infusions (infusions are longer-steeped, mineral-rich teas), are some of the oldest forms of herbal medicine. In poetic, approachable language, this poster outlines a few of our favorite tea and infusion herbs, inviting you to engage in this age-old tradition by crafting your own blends and brewing your own teas and infusions. 6.5 x 19-inch poster. A complementary display copy will be included with your first order. Please note that we only ship through USPS.
