Viral Laryngitis Clinical Trial
Official title:
Treatment of Acute Tracheitis and Laryngitis With Essential Oils of Some Aromatic Medical Plants.
This randomized, double blind, parallel group study, compared the efficacy of spray
containing aromatic essential oils of some herbal plants, against placebo in the treatment
of patients with acute viral Laryngitis or Tracheitis.
Study objectives: Primary to demonstrate a hoarseness or cough relief within 20 minutes
after first administration of treatment with the spray.
Secondary to demonstrate a reduction of a defined symptoms sum score based on symptoms and
signs comparing baseline therapy from the beginning to the end of 3 days treatment
This study compared the efficacy of spray containing aromatic essential oils of Eucalyptus
citriodora, Eucalyptus globulus, Mentha piperita, Origanum syriacum, and Rosmarinus
Officinalis, against placebo in the treatment of patients with acute viral Laryngitis or
Tracheitis.
In- vitro and clinical studies suggest therapeutic potential of aromatic herbs and trees
oils in the treatment of Laryngitis or Tracheitis. The pharmacological and clinical activity
of Eucalyptus citriodora, Eucalyptus globulus, Mentha piperita, Origanum syriacum, and
Rosmarinus Officinalis, include anti-inflammatory, anti-bacterial and anti-viral activities.
Some of these herbs and trees oils have direct activity on the respiratory tract, the
coughing reflex and the airflow in the nasal tract.
