In a double-blind randomized placebo trial, the effect of the powdered rhizome of ginger (Zingiber officinale) was tested on seasickness. Eighty naval cadets, unaccustomed to sailing in heavy seas reported during voyages on the high seas, symptoms of seasickness every hour for 4 consecutive hours after ingestion of 1 g of the drug or placebo. Ginger root reduced the tendency to vomiting and cold sweating significantly better than placebo did (p less than 0.05). With regard to vomiting, a modified Protection Index (PI) = 72% was calculated. Remarkably fewer symptoms of nausea and vertigo were reported after ginger root ingestion, but the difference was not statistically significant. For all symptom categories, PI = 38% was calculated.

Patients undergoing photopheresis are required to ingest the drug 8-MOP as part of their treatment. This drug causes nausea as a side effect. Ginger taken prior to 8-MOP may substantially reduce this side effect. This study compared patients' nausea when taking 8-MOP with and without ginger.

Ginger is well known in the form of ginger sticks or ginger ale. If these are consumed during travel, the traveler imbibes, albeit subconsciously, a healing plant for motion sickness. The efficacy of ginger rhizome for the prevention of nausea, dizziness, and vomiting as symptoms of motion sickness (kinetosis), as well as for postoperative vomiting and vomiting of pregnancy, has been well documented and proved beyond doubt in numerous high-quality clinical studies. The use of this ancient medicine for gastrointestinal problems (stimulation of digestion) has been given scientific approval. Today, medicinal ginger is used mainly for prevention of the symptoms of travel sickness.

Ginger (Zingiber officinale) is often advocated as beneficial for nausea and vomiting. Whether the herb is truly efficacious for this condition is, however, still a matter of debate. We have performed a systematic review of the evidence from randomized controlled trials for or against the efficacy of ginger for nausea and vomiting. Six studies met all inclusion criteria and were reviewed. Three on postoperative nausea and vomiting were identified and two of these suggested that ginger was superior to placebo and equally effective as metoclopramide. The pooled absolute risk reduction for the incidence of postoperative nausea, however, indicated a non-significant difference between the ginger and placebo groups for ginger 1 g taken before operation (absolute risk reduction 0.052 (95% confidence interval -0.082 to 0.186)). One study was found for each of the following conditions: seasickness, morning sickness and chemotherapy-induced nausea. These studies collectively favoured ginger over placebo.

Ginger has long been used as an alternative medication to prevent motion sickness. The mechanism of its action, however, is unknown. We hypothesize that ginger ameliorates the nausea associated with motion sickness by preventing the development of gastric dysrhythmias and the elevation of plasma vasopressin. Thirteen volunteers with a history of motion sickness underwent circular vection, during which nausea (scored 0-3, i.e., none to severe), electrogastrographic recordings, and plasma vasopressin levels were assessed with or without ginger pretreatment in a crossover-design, double-blind, randomized placebo-controlled study. Circular vection induced a maximal nausea score of 2.5 +/- 0.2 and increased tachygastric activity and plasma vasopressin. Pretreatment with ginger (1,000 and 2,000 mg) reduced the nausea, tachygastria, and plasma vasopressin. Ginger also prolonged the latency before nausea onset and shortened the recovery time after vection cessation. Intravenous vasopressin infusion at 0.1 and 0.2 U/min induced nausea and increased bradygastric activity; ginger pretreatment (2,000 mg) affected neither. Ginger effectively reduces nausea, tachygastric activity, and vasopressin release induced by circular vection. In this manner, ginger may act as a novel agent in the prevention and treatment of motion sickness.

Ginger (Zingiber officinale rhizome) is a widespread herbal medicine mainly used for the treatment of gastrointestinal diseases, including dyspepsia, nausea and diarrhoea. In the present study we evaluated the effect of this herbal remedy on the contractions induced by electrical stimulation (EFS) or acetylcholine in the isolated rat ileum. Ginger (0.01-1000 microg/ml) inhibited both EFS- and acetylcholine-evoked contractions, being more potent in inhibiting the contractions induced by EFS. The depressant effect of ginger on EFS-induced contractions was reduced by the vanilloid receptor antagonist capsazepine (10(-5) M), but unaffected by the alpha(2)-adrenergic antagonist yohimbine (10(-7) M), the CB(1) receptor antagonist SR141716A (10(-6) M), the opioid antagonist naloxone (10(-6) M) or by the NO synthase inhibitor L-NAME (3 x 10(-4) M). Zingerone (up to 3 x 10(-4) M), one of the active ingredients of ginger, did not possess inhibitory effects. It is concluded that ginger possesses both prejunctional and postjunctional inhibitory effects on ileal contractility; the prejunctional inhibitory effect of ginger on enteric excitatory transmission could involve a capsazepine-sensible site (possibly vanilloid receptors).

Zingiberis rhizoma is used as a broadspectrum antiemetic. We, therefore, conducted a comprehensive review of the literature to summarize the pharmacological and clinical effects of this popular plant material. Although clinical and experimental studies suggest that ginger has some antiemetic properties, clinical evidence beyond doubt is only available for pregnancy-related nausea and vomiting. Meta-analyses could not demonstrate the postoperative antiemetic effectiveness, and effect in motion sickness or nausea/vomiting of other ethiology. It also remains to be confirmed that proprietary ginger preparations are clinically useful to alleviate osteoarthritic or other pain, although there is no doubt that ginger constituents interfere with the inflammatory cascade and the vanilloid nociceptor. Ginger exerts in vitro antioxidative, antitumorigenic and immunomodulatory effects and is an effective antimicrobial and antiviral agent. Animal studies demonstrate effects on the gastrointestinal tract, the cardiovascular system, on experimental pain and fever, antioxidative, antilipidemic and antitumor effects, as well as central and other effects. The most relevant human pharmacological studies require a confirmatory study to exclude interaction of ginger preparations with platelet aggregation. Pharmacokinetic data are only available for [6]-gingerol and zingiberene. Preclinical safety data do not rule out potential toxicity, which should be monitored especially following ginger consumption over longer periods.

Ginger, the rhizome of Zingiber officinalis, one of the most widely used species of the ginger family, is a common condiment for various foods and beverages. Ginger has a long history of medicinal use dating back 2500 years. Ginger has been traditionally used from time immemorial for varied human ailments in different parts of the globe, to aid digestion and treat stomach upset, diarrhoea, and nausea. Some pungent constituents present in ginger and other zingiberaceous plants have potent antioxidant and anti-inflammatory activities, and some of them exhibit cancer preventive activity in experimental carcinogenesis. The anticancer properties of ginger are attributed to the presence of certain pungent vallinoids, viz. [6]-gingerol and [6]-paradol, as well as some other constituents like shogaols, zingerone etc. A number of mechanisms that may be involved in the chemopreventive effects of ginger and its components have been reported from the laboratory studies in a wide range of experimental models.

Ginger has been used safely for thousands of years in cooking, and medicinally in folk and home remedies. Advanced technology enables the validation of these traditional experiences. The National Center for Complementary and Alternative Medicine (NCCAM) has evaluated the results of the available studies, rating the reports from "suggestive" (for short-term use of Ginger for safe relief from pregnancy related nausea and vomiting), to "mixed" (when used for nausea caused by motion sickness, chemotherapy, or surgery), and to "unclear" for treating rheumatoid arthritis, osteoarthritis, or joint and muscle pain). NCCAM has funded investigators to study interactions of ginger with drugs (immunosuppressants), its effect of reducing nausea in patients receiving chemotherapy, and the safety and effectiveness of its use for health purposes, as well as its impact on inflammation. Upon completion of these studies, the scope of ginger's use will be clearly identified and incorporated into mainstream therapeutic options, thereby integrating east and west, old with new, to render ginger as a true "Universal Remedy".

This study assesses the effects of ginger on nausea and vomiting caused by pregnancy and compares it with metoclopramide medicine. This study was a randomized double-blind controlled trial. Metoclopramide, Ginger and placebo were putted in similar capsules. The medicines were administered three times a day. Then the Rhodes questionnaire was completed and its score were calculated. Data were analyzed by Chi square test, ANOVA and Repeated measurement. The intensity of changes in nausea, vomiting and Rhodes during study were statistically different in two groups of ginger and metoclopramide compared with placebo (p < 0.05), but it was not statistically significant between two groups of ginger and metoclopramide. According to our study, ginger is less effective than metoclopramide in reducing nausea and vomiting but it could be a good alternative for metoclopramide.
