Coltsfoot is a traditional Chinese medicinal material with a long history of use.

This product is the dried flower bud of Tussilago farfara L., a plant in the Asteraceae family. It is included in the 1990 edition of the Chinese Pharmacopoeia.

Coltsfoot was first seen in the "Songs of Chu" during the Spring and Autumn Period and the Warring States Period, and was called Tuxi and Kejeong in the early Han Dynasty's "Erya". Its medicinal uses were first recorded in "Shen Nong's Materia Medica" of the Eastern Han Dynasty, and it was listed as a middle grade product. It is recorded that the main symptoms include cough, inverse upper qi, asthma, laryngeal blockage, various types of epilepsy, and cold and heat evil qi. It has been recorded in the Materia Medica of successive dynasties. Su Song's "Ben Cao Tu Jing" of the Song Dynasty records: Coltsfoot is also found in Guanzhong today. The roots are purple, the stems are green and purple, and the leaves are like grasshoppers. In December, yellow flowers bloom with green-purple calyx. Remove an inch or two of soil and look like chrysanthemums at the beginning. The calyx is straight and plump. There are no children. Tao lived in seclusion (Tao Hongjing). It is said that it came out of Korea and Bai. Those who help are close to this category. There are also red flowers with leaves like lotus and straight leaves. The big ones can hold one liter, and the small ones can hold several. They are commonly known as bee-bucket leaves, also known as water-bucket leaves. This is what the Tang Dynasty Note says is as big as sunflowers and clumps; the Song Dynasty's "Compendium of Materia Medica" records: Coltsfoot flowers, in spring, people may pick them as vegetables, and those with slightly visible flowers must be used as medicine. If it is already fragrant, it will be useless. Nowadays, most people use chopsticks, but there are probably no flowers. The "Compendium of Materia Medica" of the Ming Dynasty is listed as grass grass, and its shape, habitat, production area, nature, flavor, function, etc. are described in detail.
