《山海经·山经·西山经》
山中还有一种草，形状像葵菜，散发出和蘼芜一样的气味，名称是杜衡，给马插戴上它就可以使马跑得很快，而人吃了它就可以治愈脖子上的赘瘤病。
有草焉，其状如共葵，共其臭如蘼芜，名曰杜衡，可以走马，食之已瘿。
There is also a kind of grass in the mountain, which is shaped like sunflower and has a smell similar to that of angelica. It is named Du Heng. It can be inserted into a horse to make it run faster. People can eat it to cure the swelling of the neck.
