It grows mostly in Australia, Africa and South America. Its name comes from Greek and means "covered with dew" because its leaves are covered with glands that resemble drops of dew. Its extract is used to encourage bronchial secretion fluidity. It softens and soothes the oropharyngeal mucosa and improves voice tone.
