Rating (out of 5): 2

Prickly ash (Zanthoxylum spp.) has a long history of use in traditional medicine, particularly in Chinese and Native American herbal practices, for a variety of ailments including coughs—especially those described as "spastic" or associated with bronchial irritation. Traditionally, the bark and berries have been used as a remedy for respiratory conditions due to their reputed ability to stimulate circulation, warm the body, and reduce spasms. In Traditional Chinese Medicine (TCM), prickly ash is often employed to "dispel wind" and "warm the meridians," which can be interpreted as addressing symptoms like cough and chest discomfort. Some traditional herbalists also attribute mild expectorant and antispasmodic properties to prickly ash, making it a candidate for soothing spasmodic coughs.

However, scientific evidence supporting the use of prickly ash specifically for spastic cough is limited. While some laboratory studies have identified anti-inflammatory and mild analgesic effects in prickly ash constituents (such as alkaloids and essential oils), direct research on its impact on cough—especially in human clinical trials—is lacking. Thus, its use for cough remains primarily rooted in traditional practice rather than validated by modern pharmacological research. Care should also be taken with its use, as prickly ash can interact with other medications and may not be suitable for all individuals.
