Nausea and vomiting are physiological processes experienced by every human being at some stage of their life. They are complex protective mechanisms and the symptoms are influenced by the emetogenic response and stimuli. However, when these symptoms recur frequently, they can significantly reduce the quality of life and can also be detrimental to health. The existing antiemetic agents are ineffective against certain stimuli, are expensive, and possess side effects. Herbal medicines have been shown to be effective antiemetics, and among the various plants studied, the rhizome of Zingiber officinale, commonly known as ginger, has been used as a broad-spectrum antiemetic in the various traditional systems of medicine for over 2000 years. Various preclinical and clinical studies have shown ginger to possess antiemetic effects against different emetogenic stimuli (original abstract available at https://www.ncbi.nlm.nih.gov/pubmed/23638927).
