title: [Huo is irrelevant with Huoxiang].
abstract: In ancient times, Huo referred to bean leaves and was a kind of vegetable. Though applied in medicine, Huo is recorded as vegetable in most cases and is given cultural significance for distinguishing social classes. Huoxiang was introduced to China from Jiaozhi as a kind of spice and was first recorded in Yiwu Zhi in the Han Dynasty. Later, Huoxiang was extensively used as a herb. The two plants are different in species, function and cultural value, which should be noted.
