On our sources

These entries draw on public-domain materia medica, most of it published before 1900, alongside a smaller number of modern reference works. Energetic qualities such as warming, cooling, drying and moistening are a traditional framework for describing how a plant behaves in the body, not a laboratory measurement. Where a period source states one, we cite it. Where none does, and for many North American herbs none exists, the value reflects modern herbal consensus rather than a historical text. When we cannot support a caution with real evidence, we say nothing rather than guess.
