Insights & Discussion
Ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions.
Ginger is a natural spice that is used in diverse regions to add a pungent flavor to food. Furthermore, ginger has been used as an herbal medicine for common health problems. This systematic review is the first study that has exclusively collected RCTs regarding the efficiency of ginger in several human health conditions. The clinical effects of ginger have been introduced as six subsections: nausea and vomiting, gastrointestinal function, pain, inflammation, metabolic syndromes, and other symptoms. Reportedly, ginger has been effective in a majority of studies, including those that examined the alleviation of nausea and vomiting of pregnancy, digestive function, improvement in the expression level of markers for colorectal cancer risk, and anti-inflammatory functions. Several other functions have also been regarded as beneficial in trials, with some confronting results. However, a few drawbacks regarding the quality of the trials, inconsistent evaluation systems or parameters, and the generally small size of the studies need to be noted. Therefore, systematically designed research with detailed descriptions of methodology and a sufficient pool of participants is necessary for future clinical trials to address the functional characteristics of ginger.

Phenolic extracts from turmeric and ginger have significant anti-inflammatory effects and enhance wound healing in Wistar rats.
2023 Cosmetics Effect of Phenolic Compounds Extracted from Turmeric (Curcuma longa L.) and Ginger (Zingiber officinale) on Cutaneous Wound Healing in Wistar Rats Bouchama C, Zinedine A, Rocha JM, Chadli N, El Ghadraoui L, Chabir R, et al.
Experimental Study Anti-Inflammatory Ginger Wound Healing
The study utilised the solid-liquid extraction method to obtain phenolic extracts from turmeric and ginger rhizomes. Using Wistar rats as a biological model, the researchers examined the anti-inflammatory effects of the extracts by observing the decrease in edema volume in the rat's hind paw following treatment. Moreover, the healing process of purposefully induced burns on the rat's dorsal region was monitored to evaluate the healing activity.
In the discussion of the results, it was observed that the application of creams containing the mentioned extracts resulted in complete healing after 19 days, a marked improvement compared to the control group, which only achieved 60% healing. The extracts demonstrated different levels regarding tissue repair at day 14, showing their respective potency. The study also identified diverse molecular weight distribution of phenolic compounds within the extracts, suggesting potential influence on how they affect anti-inflammatory and wound healing activities.
Fresh and dried ginger displays key botanical, phytochemical and ethnopharmacological differences, which are fundamental for their specific clinical uses in treating gastrointestinal issues.

Systematic Review Ginger Gut Microbiota
The methodology used in the research involved a retrospective comparison between Sheng Jiang (SJ, meaning fresh ginger) and Gan Jiang (GJ, meaning dried ginger), two traditional Chinese herbs. The comparison was undertaken specifically considering aspects of botany, phytochemistry, and ethnopharmacology. The research also delved into exploring the traditionally attributed use of ginger, in both its fresh and dried forms, for the treatment of gastrointestinal disorders, and its relationship with human gut microbiota - an aspect that hasn't been considered extensively previously.
The results displayed notable differences between fresh and dried ginger in terms of botany, phytochemical, and ethnopharmacological properties. Fresh and dried ginger are cultivated differently and display distinct physical appearances. This research proposed that these differences lay the foundation for how these two forms of ginger are applied clinically. Furthermore, discussing the pharmacology of gut microbiota-related gastrointestinal benefits, it is suggested that fresh and dried ginger could present innovative and potent avenues for preventing and treating gastrointestinal disorders.

Ginger emerges as a safe and effective treatment for nausea and vomiting in early pregnancy.
2018 Foods How Safe Is Ginger Rhizome for Decreasing Nausea and Vomiting in Women during Early Pregnancy? Stanisiere J, Mousset PY, Lafay S
Systematic Review Ginger Morning Sickness
Nausea and vomiting of pregnancy (NVP) affect 7 in 10 pregnant women, significantly impacting their quality of life. Concerns about the safety of traditional antiemetic drugs have led to the consideration of natural options like ginger, which has shown favorable risk/benefit ratios and strong evidence. Ginger supplements with 0.5 to 2 g of root per day can effectively alleviate NVP. However, ensuring ginger quality is crucial, especially in monitoring methyleugenol concentration for potential toxicity. The variability in gingerol composition among supplements underscores the importance of stringent quality control measures. Studies have not found significant reproductive or developmental risks associated with ginger use during pregnancy, but medical supervision and case-specific evaluation are essential. Further research on ginger's effect on platelet aggregation in pregnant women is recommended.
Ginger could be considered a harmless and possibly effective alternative option for women suffering from nausea and vomiting during pregnancy.
2014 Nutrition Journal A systematic review and meta-analysis of the effect and safety of ginger in the treatment of pregnancy-associated nausea and vomiting Viljoen, E., Visser, J., Koen, N. et al.
Systematic Review Ginger Morning Sickness
This review suggests potential benefits of ginger in reducing nausea symptoms in pregnancy (bearing in mind the limited number of studies, variable outcome reporting and low quality of evidence). Ginger did not significantly affect vomiting episodes, nor pose a risk for side-effects or adverse events during pregnancy. Based on evidence from this systematic review, ginger could be considered a harmless and possibly effective alternative option for women suffering from nausea and vomiting during pregnancy.
