Therapy—Yerba Santa has a soothing influence upon irritating, dry, hacking, persistent cough.

It is of value in chronic bronchitis, chronic pneumonitis and in phthisis pulmonalis, in allaying the cough which seems to increase the patient's feebleness and advance the development of the disease. It is an excellent remedy combined with grindelia robusta. It acts well in all forms of cough where there is dryness of the mucous membranes, in conjunction with other directly indicated remedies. It is prepared in the form of a syrup, and like prunus virginiana, can be made a basis or vehicle for other agents. The syrup conceals the bitter taste of quinine admirably.
