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

Because of its delicate violet aroma, iris is used in perfume, toothpaste, and cosmetics.

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 rhizome of the iris plant is a strong purgative but not so intense when dry. It is also used in several bronchial medicines due to its notable expectorant and antitussive properties. It is also a diuretic.
