Therapy. External. Grindelia promotes reparation in damaged conditions of the epithelium. It is especially valuable in chronic skin diseases with feeble circulation and tendency to ulceration. For indolent ulcers a lotion of the specific medicine (2 fluidrachms to Water, 16 fluidounces) may be applied freely upon compresses.
Action. The grindelias have a bitter, acrid taste, leaving an unpleasant, persistent, acrid sensation in the mouth and cause an increased flow of saliva. The kidneys are excited by them and diuresis is increased, while upon the bronchial membranes they produce a primary increase of secretion followed by a lessened expectoration and diminution of the rate of breathing. They are eliminated by the bronchi and the kidneys. Marked relaxation of the bronchi is produced by grindelia.
primary-actions. Gum weed acts primarily as: Antispasmodic, Bronchodilator, Expectorant (relaxing), Mucolytic, Anti-inflammatory, Anticatarrhal. Secondary actions include Antimicrobial.
