Balloon-Flower (Platycodon grandiflorus) has a long history of use in traditional East Asian medicine, particularly in Chinese and Korean herbal practice. Its root, known as Jie Geng in Traditional Chinese Medicine (TCM), is commonly used to address respiratory issues, including coughs, sore throat, and conditions associated with phlegm and congestion. In TCM, it is specifically noted for its ability to "open up the lungs" and "disperse congestion," which has led to its traditional use for supporting the Eustachian tubes, as these structures can become blocked in the context of upper respiratory tract infections or allergies. The rationale is that by addressing phlegm and inflammation in the upper respiratory tract, Balloon-Flower may help relieve pressure or blockage in the Eustachian tubes.

Scientific evidence to confirm these specific effects is limited. Some pharmacological studies indicate that Platycodon grandiflorus root contains saponins and other compounds with anti-inflammatory and expectorant properties, which may indirectly support ear, nose, and throat health. However, there are no robust clinical trials directly demonstrating its efficacy for Eustachian tube dysfunction. Thus, its use for this indication is primarily supported by traditional herbal knowledge rather than modern scientific validation.
