Book excerpt: Twenty plants, including familiar trees like the aspen, birch, spruce, and poplar, as well as lesser-known plants like Labrador tea, cow parsnip, and buffalo berry, form the soul of herbalist Robert Rogers’s medicine kit. Herbal Allies chronicles the journey that led Rogers to become an herbalist and shares his deep knowledge of the plants that shaped his practice. The author weaves personal experience, observations, knowledge from indigenous healers, and many years of expertise from his practice as a professional herbalist and clinical professor to present a unique and fascinating narrative that not only limns one man's vital connection to plants but also provides invaluable information on effectively using plant medicine for the prevention and treatment of a variety of health conditions.
