Balloon Flower
Platycodon grandiflorus
Under the name Jie Geng, the dried root of the balloon flower has been a cornerstone of Chinese herbal medicine for centuries, traditionally combined with other herbs to help clear the lungs and ease coughs heavy with phlegm. In Korea, the same root is known as doraji, where it crosses the line from medicine cabinet to dinner table as a beloved, crunchy banchan served at holidays and ancestral rites. Long before either tradition, farmers and foragers simply admired the plant for its theatrical buds, each one inflating like a tiny lantern before bursting open into a star.

Traditional preparations.
A simple, traditional preparation echoing the way Jie Geng has long been simmered in East Asian herbal practice to make a warming, slightly bitter root tea.
Traditionally, a decoction is made by gently simmering 3 to 5 grams of dried, sliced root in 2 cups of water for 15 to 20 minutes, then straining and sipping warm.
Safety.
Raw balloon flower root can irritate the mouth and throat, so it is always peeled and soaked or parboiled before eating, or simmered as a decoction when dried. Avoid it during pregnancy and breastfeeding, and use caution with bleeding disorders or blood-thinning medication.
