Ammi Visnaga Oil is a powerful bronchial antispasmodic which can lead to freedom from allergic bronchial asthma. All my sources indicate, when inhaled, it can be a powerful weapon against asthma, especially bronchial asthma. Any essential oil can trigger an asthma attack, more or less at random. Among those who suffer from this disease, however, Amni Visnaga Essential Oil appears to actually ease the attack away, by both relaxing the bronchial spasms and by dilating the bronchia. For this reason, inhalation could prove helpful for both asthma and bronchitis.
