A field guide to the language
The art of an
herbal action.
Words that help us understand a plant’s traditions—and ask better questions about its benefits.
In herbal medicine, a classification is a way into a story. A nervine may belong to an evening ritual; a bitter brings a distinctive taste to the digestive tradition. Neither label tells us that every preparation has the same effects.
The first entries below describe herbal actions and concepts. The later entries group areas of use or research. Each plant profile explains the relevant species, part, preparation, evidence, and cautions.
Traditional use and clinical evidence answer different questions. The European Medicines Agency makes that distinction in its assessments of peppermint leaf, marshmallow root, and the adaptogenic concept.
