Synopsis
Source of validity: Traditional
Rating (out of 5): 2
Aster tataricus, known as "Zi Wan" in Traditional Chinese Medicine (TCM), has a long-standing historical use for treating respiratory conditions, particularly coughs and wheezing. In classic TCM texts, it is described as an herb that enters the lung meridian and is commonly included in formulations aimed at resolving phlegm and relieving cough or dyspnea (shortness of breath/wheezing). The rationale is that Aster tataricus is thought to moisten the lungs, expel phlegm, and stop coughs. This traditional use remains prevalent in Chinese herbal practice today, especially in multi-herb formulas. Scientific studies directly evaluating Aster tataricus for wheezing or asthma in humans are limited. Some in vitro and animal studies suggest the herb has anti-inflammatory and expectorant properties, and may modulate cytokines or relax airway smooth muscle, which could theoretically alleviate symptoms like wheezing. However, human clinical trials are lacking, and the evidence is not robust enough to be rated highly. In summary, the use of Aster tataricus for wheezing is primarily justified by its traditional application in TCM, with only preliminary scientific support from basic studies. Its evidence base for this specific indication is rated as low to moderate (2/5), pending further scientific validation.
