Ecology

Platycodon grandiflorus is a perennial plant which is commonly grown in mountains and fields. It is 40 to 100 centimeters high and has thick roots, and white juice comes out when the stem is cut. Leaves are 5 to 12 centimeters long, with narrow ends and teeth on the edges.

Flowers bloom purple or white in July and August, with one or several running upward at the end of the circle. The flower crown is divided into five branches in the shape of an open bell.

It lives throughout Japan, China, and eastern Siberia, including the Korean Peninsula.

Cultivation

This plant is hardy down to , and can be cultivated in USDA zones 3A to 9b. It dies down completely in winter, reappearing in late spring and flowering in summer. However, plants are widely available from nurseries in full flower from April onwards.

Though the species has blue flowers, there are varieties with white, pink, and purple blooms. 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.

Uses

Culinary

Korea

In Korea, the plant as well as its root are referred to as (). The root, fresh or dried, is one of the most common vegetables. It is also one of the most frequent ingredients in bibimbap. Sometimes, rice is cooked with balloon flower root to make . Preparation of the root always involves soaking and washing (usually rubbing it with coarse sea salt and rinsing it multiple times), which gets rid of the bitter taste.

The root is also used to make desserts, such as . Syrup made from the root, called (balloon flower root honey), can be used to make (balloon flower root tea). The root can be used to infuse liquor called , typically using distilled soju or other unflavored hard alcohol that has an ABV higher than 30% as a base.

In addition, other ingredients include calcium, fiber, iron, minerals, proteins and vitamins. Bottlenose is a good product for its thick roots, faithful interior, and strong taste. It is used as an anti-inflammatory, Jinhae, analgesic, sedative, and fever agent. It is also effective in reducing cholesterol, which can be effective in blood related diseases and high blood pressure. Doraji is good for young children and elderly people who have weak immune systems that are vulnerable to respiratory diseases, as well as for asthma, which can be called respiratory illness.

Medicinal

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.Nyakudya E.; Jeong JH.; Lee NK.; Jeong YS. (2014) “Platycosides from the Roots of Platycodon grandiflorum and Their Health Benefits.” Preventative Nutrition and Food Science 19 (2): 59–68. . 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, necessitate further research.

China
