Atractylodes, particularly Atractylodes macrocephala (Bai Zhu) and Atractylodes lancea (Cang Zhu), is widely used in Traditional Chinese Medicine (TCM) to support the treatment of colds, specifically as a component in formulas aimed at alleviating symptoms such as nasal congestion and dampness. In TCM theory, Atractylodes is believed to strengthen the spleen, dry dampness, and expel wind-cold pathogens from the body, which is thought to help the body recover from colds and respiratory illnesses. The herb is commonly included in formulas like “Cang Er Zi San” and “Xiang Sha Liu Jun Zi Tang,” which are prescribed for symptoms such as nasal congestion, runny nose, and general malaise associated with common colds.

However, scientific evidence supporting the use of Atractylodes as a decongestant or for treating colds is limited. Most available studies focus on its anti-inflammatory and immunomodulatory properties, which could, in theory, help with symptoms of colds, but direct clinical trials in humans for these specific uses are lacking. The evidence base, therefore, remains largely traditional, with anecdotal reports and centuries of use in TCM rather than robust modern scientific validation. Thus, while Atractylodes continues to be used in traditional herbal practice for colds and congestion, more research is needed to confirm its efficacy and mechanisms in this context.
