Balloon Flower (Platycodon grandiflorus) has a longstanding history of use in traditional East Asian medicine, particularly in Chinese and Korean herbal practices, to address respiratory ailments such as coughs, sore throats, and congestion. In Traditional Chinese Medicine (TCM), the root of Balloon Flower, known as Jie Geng, is classified as an herb that “opens up the lungs” and is commonly included in formulas aimed at resolving phlegm and promoting the flow of lung qi. It is believed to help expel pus, ease sore throats, and alleviate symptoms of sinus and bronchial congestion. Historical materia medica texts describe its use for conditions involving mucus, blocked sinuses, and difficulty breathing.

Modern scientific evidence for Balloon Flower’s effectiveness in treating sinus congestion specifically is limited. Laboratory and animal studies indicate that saponins and other constituents in the root may have anti-inflammatory, expectorant, and immunomodulatory effects, which could theoretically support respiratory health. However, most clinical research focuses on cough and bronchitis rather than sinus congestion per se. Thus, while the tradition is robust and plausible mechanisms exist, rigorous human clinical trial data confirming its efficacy for sinus congestion are lacking.

In summary, the use of Balloon Flower for sinus congestion is primarily justified by traditional knowledge, with limited but suggestive preclinical scientific support.
