Do ricola cough drops have antihistamines in them

Ricola is a cough suppressant drops and soothes throat. Its main ingredients are herbs, which is mostly minty in flavor like the sage, lemon balm and peppermint, which act as oral anesthetic and cough suppressant, the mallow has calming effect while thyme is good for the cough. I do not think it has antihistamine and if they do, they must indicate proper caution concerning the effects of antihistamine in the body.
