Low-Dose Oral Ginger Improves Daily Symptom Scores in Asthma.

A significant number of individuals with asthma have poorly controlled daily symptoms and utilize dietary supplements such as ginger in a quest for improved symptom control; however, its effectiveness at improving the control of symptoms is unproven. We questioned whether low-dose oral ginger would improve subjective and objective measurements of asthma control in mild-to-moderate asthmatics. We performed a randomized, placebo-controlled, double-blinded study of a low dose (1 g twice daily) of a dietary supplement of ginger in 32 mild-to-moderate uncontrolled asthmatics over a 2-month trial period while maintaining daily conventional asthma therapies.

Pharmacokinetics of Gingerols, Shogaols, and Their Metabolites in Asthma Patients.

6-Gingerol and 6-shogaol are the most abundant gingerols and shogaols in ginger root and have been shown to reduce the asthmatic phenotype in murine models of asthma. Several studies have described the pharmacokinetics of gingerols and shogaols in humans following the oral ingestion of ginger, while little was known about the metabolism of these components in humans, particularly in patients with asthma. In this study, a dietary supplement of 1.
