Stewardship

Gentian (Gentiana lutea) is wild-harvested in European mountain meadows; Alpine stands declining from overharvest. Choose cultivated where possible. Stewardship: the bitter that opens digestion is the teacher of bitterness itself — a virtue we have lost in modern sweet-dominated palates.

In the traditional record

Gentian (Gentiana lutea) — the genus name honors Gentius, king of Illyria (2nd century BCE), who according to Pliny and Dioscorides discovered the medicinal use of the root; cultivated and used throughout European herbal tradition (Hildegard, Culpeper, Commission E) as the archetypal bitter tonic for sluggish digestion and hepatic insufficiency.

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.
