Antitussive effect Aidi tea decoction and its extract, catechin No. 1 have obvious antitussive effects on coughs caused by electrical stimulation of cat superior laryngeal nerves and mice caused by ammonia spray, and catechin No. 1 is particularly effective , May be the main cough suppressant ingredient of Aidi Tea. Its antitussive strength is equivalent to 1/4 to 1/7 of cocaine based on the dose, and it is intolerable even if it is administered to cats continuously for 23 days. It is speculated that the site of antitussive effect is in the center, possibly in the midbrain. Ai Dicha and Dwarf Tea No. 1 have no effect on reducing the dose of thiopental sodium in rats, and no obvious analgesic effect on mice. Large doses have no hypnotic effect on animals.

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.
