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.
"There are two valuable extracts of ginger, essential oil which varies as 0.8–4.2% and oleoresin in the range of about 7% depending on its origin habitat and agronomic treatment of culture . Ginger oil possesses the natural aroma of crude ginger and is globally used in flavour, perfumer, and pharmaceutical and liqueur industry . The therapeutic properties of ginger oil are antiseptic, antispasmodic , carminative, cephalic, expectorant, febrifuge, laxative, and stomachic  . "
[Show abstract][Hide abstract] ABSTRACT: The solvent-free microwave extraction of essential oil from ginger was optimized using a 23 full factorial design in terms of oil yield to determine the optimum extraction conditions. Sixteen experiments were carried out with three varying parameters, extraction time, microwave power, and type of sample for two levels of each. A first order regression equation best fits the experimental data. The predicted values calculated by the regression model were in good agreement with the experimental values. The results showed that the extraction time is the most prominent factor followed by microwave power level and sample type for extraction process. An average of 0.25% of ginger oil can be extracted using current setup. The optimum conditions for the ginger oil extraction using SFME were the extraction time 30 minutes, microwave power level 640 watts, and sample type, crushed sample. Solvent-free microwave extraction proves a green and promising technique for essential oil extraction.

"In addition to its nutritional and flavour aspects, it has long been considered to have potential for multiple health benefits as illustrated by its use as a traditional medicine against headache, nausea, colds, and arthritis for as long as a thousand years by traditional people in Asia. More recent assessments by health scientists have shown that ginger may have a role in reducing certain cancers, diabetes, and high blood pressure and also have anti-inflammatory properties (Anonymous, 2010; Hamilton, 2011; Krell and Stebbing, 2012; Langner et al., 1998; Nicoll and Henein, 2009; Shukla and Singh, 2007; Vasala, 2010; Wright, 2011; Zachariah, 2008). However, there are still a few, albeit uncommon, minor adverse effects resulting from the consumption of ginger; these include slight gastrointestinal distress, heartburn, and oral irritation. "
[Show abstract][Hide abstract] ABSTRACT: Ginger is considered by many people to be the outstanding member among 1400 other species in the family Zingiberaceae. Not only it is a valuable spice used by cooks throughout the world to impart unique flavour to their dishes but it also has a long track record in some Chinese and Indian cultures for treating common human ailments such as colds and headaches. Ginger has recently attracted considerable attention for its anti-inflammatory, antibacterial and antifungal properties. However, ginger as a crop is also susceptible to at least 24 different plant pathogens, including viruses, bacteria, fungi and nematodes. Of these, Pythium spp. (within the kingdom Stramenopila, phyllum Oomycota) are of most concern because various species can cause rotting and yield loss on ginger at any of the growth stages including during postharvest storage. Pythium gracile was the first species in the genus to be reported as a ginger pathogen, causing Pythium soft rot disease in India in 1907. Thereafter, numerous other Pythium spp. have been recorded from ginger growing regions throughout the world. Today, 15 Pythium species have been implicated as pathogens of the soft rot disease. Because accurate identification of a pathogen is the cornerstone of effective disease management programs, this review will focus on how to detect, identify and control Pythium spp. in general, with special emphasis on Pythium spp. associated with soft rot on ginger.
"Ginger (Zingiber officinale) has traditionally been used in China for more than 2000 years for gastrointestinal symptoms such as nausea and vomiting. Ginger has been used as an antiemetic after chemotherapy, motion sickness, Gynecological Surgery, gynaecological laparoscopic surgeries, gynaecological day care surgeries. "
[Show abstract][Hide abstract] ABSTRACT: Post-operative nausea and vomiting (PONV) frequently hampers implementation of ambulatory surgery in spite of so many costly antiemetic drugs and regimens.
The study was carried out to compare the efficacy of ginger (Zingiber officinale) added to Ondansetron in preventing PONV after ambulatory surgery.
It was a prospective, double blinded, and randomized controlled study. From March 2008 to July 2010, 100 adult patients of either sex, aged 20-45, of ASA physical status I and II, scheduled for day care surgery, were randomly allocated into Group A[(n = 50) receiving (IV) Ondansetron (4 mg) and two capsules of placebo] and Group B[(n = 50) receiving IV Ondansetron (4 mg) and two capsules of ginger] simultaneously one hour prior to induction of general anaesthesia (GA) in a double-blind manner. One ginger capsule contains 0.5 gm of ginger powder. Episodes of PONV were noted at 0.5h, 1h, 2h, 4h, 6h, 12h and 18h post- operatively.
Statistically significant difference between groups A and B (P < 0.05), was found showing that ginger ondansetron combination was superior to plain Ondansetron as antiemetic regimen for both regarding frequency and severity.
Prophylactic administration of ginger and ondansetron significantly reduced the incidence of postoperative nausea and vomiting compared to ondansetron alone in patients undergoing day care surgery under general anaesthesia.
