Pranarôm Olivardilla 5 ml is a 100% pure and natural essential oil from the flowering tops of Olivardilla. Olivardilla, or Inula graveolens in its scientific name, is a plant that only flowers in autumn and is known for its mucolytic, anti-catarrhal, antispasmodic, antibacterial and anti-infectious properties. It is also believed to act favourably against coughs, as it helps to inhibit the cough reflex thanks to its antitussive qualities. In addition to this, the oil is also considered to act as a possible cardiac tonic and cardiac regulator. In this sense, the use of this natural liquid product has been mainly intended for cases of respiratory conditions, common colds or asthma episodes involving secretions or cardiac fatigue.
