Rating (out of 5): 2

Ferula assafoetida, commonly known as asafoetida, has been traditionally used in Ayurvedic, Unani, and Persian medicine as a remedy for various respiratory ailments, including cough. Historical texts and ethnobotanical records describe the use of asafoetida as an expectorant and antitussive agent. It was often administered in powders, tinctures, or as part of herbal formulations to help relieve coughs, bronchitis, and asthma-like symptoms. The resin contains volatile oils, such as ferulic acid and umbelliferone, which have been attributed with anti-inflammatory, antispasmodic, and antimicrobial properties that may help in soothing irritation of the respiratory tract and reducing the frequency of coughing.

However, while there is a strong tradition of its use, scientific validation is limited. Only a few laboratory and animal studies have indicated that asafoetida may possess bronchodilatory and antitussive effects, but robust clinical trials in humans are lacking. Therefore, its use for cough is primarily grounded in traditional medicine systems, with low to moderate supporting evidence from preclinical studies. Further research, particularly well-designed clinical trials, is needed to confirm these effects and establish safety and efficacy in humans.
