Ginger's Therapeutic Potential in Asthma

Primary Objective: The primary endpoint is a clinically significant improvement in tolerance to inhaled methacholine (PD20). Secondary Objectives: 1) To determine if oral daily ginger extract intake - decreases fractional excretion of nitric oxide; decreases blood eosinophilia; decreases asthma-associated cytokines in serum; decreases medium chain fatty acids; improves asthma symptoms; and 2) Establish pharmacokinetic parameters of biologically active components of ginger in adult asthmatics.
