Look For Me by Janet Shawgo
A lantern, a medicine pouch, and a bell to stop the gunfire: That was all nurses took into the Civil War battlefields as they sought out injured men, boys, and women disguised as men. Among them is Sarah Bowen, a young healer from Georgia, whose use of herbal medicine brings her scorn from most field doctors even as it saves countless lives...What the reader gains is an understanding not only of the medicinal uses of native plants, but of the women’s incredible resourcefulness.
