Herba Tussin is a traditional cough and bronchial tea that supports the respiratory system* with demulcent herbs to soothe respiratory membranes, antitussive herbs to relieve cough and expectorant herbs to promote normal bronchial secretion.* Eucalyptus and licorice teas are traditionally used for non-serious upper respiratory tract conditions. Slippery elm is a safe and effective demulcent (soothing herb).
