Ferula asafoetida is an endemic species in Iran and is rich in oleo-gum resin with high economic value in the world. One important application of F. assafoetida is its traditional use for the management of respiratory ailments. The aim of this review was to collect papers dealing with F. asafoetida oleo-gum resin in respiratory tract128;™s diseases in modern medicine. For preparing the manuscript the scientific databases (Google scholar, PubMed, Springer, Science Direct, Magiran), books, thesis, etc. were searched using the keywords of "Ferula asafoetida", "Ferula scorodesma", "Scorodesma foetida", Ferula asafoetida is an endemic species in Iran and is rich in oleo-gum resin with high economic value in the world.

The results of the investigation confirmed the traditional belief on the efficacy of Ferula asafoetida in the treatment of respiratory viral infection (Coronavirus, influenza), cigarette smoking, asthma, cough and cancer, but most studies were limited to in vitro. There was only one registered randomized, blinded, placebo controlled clinical trial for 300 mg F. asafoetida aqueous extract capsules (three times a day for 14 days) on 40 patients with COVID-19 without any published results. Although, the studies implied the efficacy of F. asafoetida in the treatment of respiratory treatments, but design large clinical studies for evaluating its efficacy and safety is essential in future investigations.Northex asafoetida" plus 128;œrespiratory tract128;, "respiratory disorder" 128;œinfection128;, "cough", "trachea", "traditional medicine" up to Feb 2022 and the collected data were summarized, analyzed, and discussed.
