Frequently Asked Questions
What is Korean Bellflower Root?
Korean Bellflower Root (Platycodon grandiflorus), known as doraji in Korean cuisine, is a perennial herb from the Campanulaceae family. It has been used for centuries in Korean and Chinese traditional medicine primarily for respiratory conditions. Its key bioactive compounds are triterpenoid saponins, particularly platycodin D, which have demonstrated expectorant, anti-inflammatory, and immune-modulating properties.
What is the recommended dosage and is it safe?
Traditional dosages range from 3 to 6 grams of dried root daily as a decoction. Standardized extracts are typically dosed at 500 to 1,000 mg per day. It is generally safe at culinary and standard supplemental doses. High doses may cause GI discomfort due to saponin content. Pregnant and nursing women should avoid therapeutic doses due to insufficient safety data.
What are the main benefits of Korean Bellflower Root?
The primary traditional and research-supported benefit is respiratory health — platycodin D acts as a natural expectorant, helping to clear mucus and support lung function. It also demonstrates immune-stimulating properties through its polysaccharides and provides antioxidant protection via flavonoids. In Korean culture, it is commonly eaten as a side dish (namul) and used in soups for general wellness.
