The great Greek physician, pharmacologist, botanist, and author Pedanius Dioscorides devoted a long paragraph in the first chapter of his De Materia Medica to the virtues of the iris plant. Andres de Laguna (16th century) translated Dioscorides’s works into Spanish and commented on them, remarking on their multiple properties, such as “wonderfully purging the brain when its juice is taken through the nose.” Some years later, the plant was forgotten; however, recently, its virtues have been extolled again.

Healing Properties and Indications
Its root contains 50 percent starch, mucilage, and a very aromatic essential oil that gives the plant its peculiar violet aroma. When fresh, the plant’s rhizome is a strong laxative but not so intense when dry. Due to its notable expectorant and antitussive properties, it is also used in several bronchial medicines. It is also a diuretic.
