According to legend, there was a young medicine farmer named Platycodon grandiflorum in Tongbai Mountain who went out to collect medicine every day. One day, as soon as he entered the mountain, a scent of fragrance hit his nostrils. Looking closely, I saw a wild chrysanthemum growing on the cliff, swaying in the wind. Suddenly, the goldenrod was trampled down by a wild deer. The kind-hearted Platycodon was very distressed, so she climbed up the vines with her hands and stepped on the cliff with all her strength. Finally, she climbed up and helped up the wild golden chrysanthemum. Unexpectedly, at this moment, Kikyo jumped into the air and fell from the cliff. While unconscious, he vaguely heard someone calling Brother Platycodon. When he opened his eyes, he saw a flower-like woman guarding him. The woman said: "I am the Chrysanthemum Fairy who descended from heaven. In memory of her saving grace, I would like to pledge myself to you and become a lifelong partner." Platycodon agreed. From then on, one collected herbs and the other weaved, and although their life was poor, it was harmonious and happy. Unexpectedly, the Emperor of Heaven blamed him, and with a thunder, he took the Chrysanthemum Fairy away. At this time, Platycodon heard the sky calling: "Brother Platycodon, take care of yourself! Bury my body on the road to collect herbs. When you see the tomb, you will see me!" The voice suddenly stopped, and a torn chrysanthemum seedling fell on the ground. in front of me. Platycodon cried bitterly and jumped down the valley with chrysanthemum seedlings in her arms. In an instant, the mountain collapsed and the cliffs collapsed, forming a tomb. Every year thereafter, a grass would grow on the tomb, and people named it Platycodon grandiflorum. Because he embraces chrysanthemums, the platycodon that has been medicated is the chrysanthemum heart.
