Platycodon grandiflorus (from Ancient Greek "wide" and "bell") is a species of herbaceous flowering perennial plant of the family Campanulaceae, and the only member of the genus Platycodon. It is native to East Asia (China, Korea, Japan, and the Russian Far East). It is commonly known as common balloon flower or balloon flower (referring to the balloon-shaped flower buds), and, depending on the region, Korean bellflower, Chinese bellflower, or Japanese bellflower.
Growing to 60cm (24in) tall by 30cm (12in) wide, it is an herbaceous perennial with dark green leaves and blue flowers in late summer. A notable feature of the plant is the flower bud which swells like a balloon before fully opening. The five petals are fused together into a bell shape at the base, like its relatives, the campanulas. There are varieties with white, pink and purple blooms in cultivation. In Korea, white flowers are more common. This plant together with its cultivars 'Apoyama group' and 'Mariesii' have gained the Royal Horticultural Society's Award of Garden Merit.

The extracts and purified platycoside compounds (saponins) from the roots of Platycodon grandiflorum may exhibit neuroprotective, antimicrobial, anti-inflammatory, anti-cancer, anti-allergy, improved insulin resistance, and cholesterol-lowering properties. Evidence for these potential effects was mainly observed in vitro, with the exception of cholesterol lowering effects documented in vitro and in rats. The lack of efficacy and limited safety data in humans however, necessitates further research.
In Korea, the roots are commonly used for treating bronchitis, asthma, tuberculosis, diabetes, and other inflammatory diseases. In China, they are used as a cough suppressant and expectorant for common colds, cough, sore throat, tonsillitis, and chest congestion.
