Labdanum is a rich brown resin sourced from the cistus shrubs of the species rockrose. This sticky resin is used since the ancient times as a natural remedy and perfume ingredient. Back in the past, the resin was collected from the beards and thighs of goats and sheep that gazed on the shrubs. Later on, the wooden instruments for sweeping the shrubs are invented. The resin was used to treat various ailments such as menstrual problems, rheumatism, and common colds. Today, the resin is mainly used in the perfume industry and obtained by boiling the leaves and twigs, by solvent extraction, or steam distillation.
