The *Yizong Xinfa* (Medical Master's Heart Methods) states: The condition originally known as "Rouci" (Fleshy Spur), commonly called Jiyan (Corn/Clavus), grows on the toes, resembling a chicken's eye. Its root is sunken into the flesh, while the top protrudes hard and causes pain, making walking difficult. This arises from foot-binding or running in narrow shoes that cause compression; all these factors can lead to its formation. It is advisable to apply Jiawei Taiyi Gao (Modified Great Emperor Ointment) to moisten the area, or crush Ziyuzan Gen (Rhizoma Tricyrtidis) and apply it covered with oiled paper. Alternatively, mixing equal parts of Digupi (Cortex Lycii) and Honghua (Flos Carthami) into fine powder and applying it with sesame oil are also effective. (From *Yizong Jinjian*)
