Introduction: Bellflower Root - A Treasure for Respiratory Health

Bellflower root (Platycodon grandiflorus), known as "doraji" in Korean and "jiegeng" in Chinese medicine, has been cherished for thousands of years across East Asia for both culinary and medicinal purposes. In traditional medicine, it's renowned for its exceptional benefits for bronchial and lung health. The characteristic slightly bitter taste of bellflower root comes from its saponin content - the key compound behind its remarkable health benefits.

During seasonal changes or on days with heavy air pollution, a cup of doraji tea is one of the best traditional remedies for a scratchy throat or persistent phlegm. Today, we'll explore the scientific benefits of bellflower root and share easy recipes for making doraji syrup and doraji tea at home.

1. Key Health Benefits of Bellflower Root

1.1 Respiratory Health and Phlegm Expulsion
