Soothing, softening, and beautifying

This page groups plants by their traditional hot, cold, moist or dry quality under the old humoral system of medicine. Wikipedia notes that "Galen supposed that a cold and wet thing could be used to treat an imbalance in a hot and dry organ," the reasoning this kind of plant classification rests on. Browsing by humoral temperament lets a visitor see which plants a historical healer would have reached for to correct a given imbalance.
