Judging from its description, it is difficult to conclude that it is the same plant as the so-called Yexiahong in “Li Shi Cao Mi”. The fourteenth volume of “A Study of Plant Names” contains a small green growing sandy land, high and small, with small pink flowers, drooping cusps, and red fruit in winter.

Expectorant and antiasthmatic effects Aidi tea decoction has obvious expectorant effects on mice by gavage (phenol red method), and the intensity of action is equivalent to that of platycodon grandiflorum. The effect of intraperitoneal injection is stronger, but it has no effect on rabbit eye conjunctiva. Obvious irritation, indicating that its expectorant effect may be produced by absorption.
