Gingerol is a bioactive compound found in fresh ginger that contributes to its pungent flavor. As research continues to uncover the medicinal properties of ginger, gingerol has come under focus for its antioxidant and anti-inflammatory effects that may benefit health in numerous ways. The purpose of this article is to explore what gingerol is, its known and potential uses and health applications, safety considerations, and recommendations regarding this promising natural compound.
What is gingerol?
Gingerol is a phenolic compound found abundantly in fresh ginger root (Zingiber officinale). Chemically known as [6]-gingerol based on its molecular structure, it is mainly responsible for the distinctive spiciness and aroma of ginger. Along with other gingerols and shogaols, [6]-gingerol makes up around 4-7.5% of the weight of fresh ginger root. Research indicates gingerol and related compounds have antioxidant, anti-inflammatory, antimicrobial, and gastroprotective properties.
Health benefits of gingerol
Emerging research highlights various potential therapeutic benefits of ginger and gingerol related to its antioxidant and anti-inflammatory properties. While larger scale human studies are still needed, some promising health benefits include:
1. Reducing nausea and vomiting - Multiple reviews indicate effectiveness for reducing chemotherapy-related and postoperative nausea. A 2016 meta-analysis of randomized controlled trials found that ginger was more effective than placebo in alleviating pregnancy-related nausea and vomiting as well.
2. Supporting gut and digestion - Gingerol may protect against gastric ulcers, with animal studies showing protective effects in the gastrointestinal tract. A 2019 double blind, placebo-controlled pilot study also found reduced abdominal discomfort, bloating, and improved bowel habits in women with irritable bowel syndrome after ginger supplementation.
3. Relieving pain - Ginger and gingerol have shown success alleviating pain and inflammation associated with osteoarthritis and muscle soreness in some trials. A 2010 study on patients with osteoarthritis of the knee saw significant reductions in knee pain after 6 weeks of ginger supplementation compared to placebo.
4. Aiding weight loss - Animal model studies found gingerol helped reduce body weight, indicating potential weight management benefits. More research needs to demonstrate effects in overweight human subjects.
5. Supporting cardiovascular health - Ginger Root Extract Powder displays antihyperlipidemic and anti-atherosclerotic activities that may support heart health. An animal model study in diet-induced obese rats also showed cardioprotective effects from ginger with reductions in ventricular hypertrophy and fibrosis.
6. Exhibiting antimicrobial effects - Research shows [6]-gingerol has antibacterial, antifungal, and antiparasitic properties against various pathogens. However, clinical trials are essential to determine efficacy in human infections.
Uses of gingerol
Culturally, ginger has been used for centuries in foods and traditional healing systems. Today, usage focuses on harnessing gingerol's bioactive effects.
Culinary uses: The phenolic gingerols provide fresh ginger's characteristic zing, making it a versatile ingredient in global cuisines. Gingerol's impact diminishes with heating or drying, so fresh ginger best preserves gingerol content. Ginger powder contains roughly 50% less gingerol than the fresh root.
Ayurvedic medicine uses ginger for its warming, digestive properties. Traditional Chinese medicine utilizes ginger to relieve nausea, diarrhea, and other GI disturbances.
Modern applications also recognize gingerol's antioxidant, anti-inflammatory, and antimicrobial properties. It holds potential for development into functional foods, nutritional supplements, pharmaceuticals, cosmetic products, and more.
1 Potential medicinal applications
While human studies are limited to date, [6]-gingerol shows promise as a therapeutic supplement to help alleviate certain inflammatory conditions, GI issues, microbe infections, side effects of chemotherapy and possibly even support weight management when used prudently:
Inflammation-related issues like arthritis, muscle pain: Gingerol may help via anti-inflammatory and analgesic effects demonstrated in osteoarthritis and exercise-induced muscle injury studies. Heart health: Gingerol improved lipid profiles and reduced atherosclerotic lesions indicative of vascular-protective properties that lower heart disease risk. Chemotherapy side effects: Gingerol containing interventions clinically reduced acute chemotherapy-related nausea versus placebo in multiple studies. Gut issues like ulcers and IBS: Gingerol exhibited gastroprotective effects against ulcer formation and colitis in rodents via antioxidant and anti-inflammatory activities. Antimicrobial benefits: Gingerol may combat bacterial and fungal infections, with lab research showing effectiveness against foodborne pathogens, yeasts, and parasites. Obesity & weight loss: Animal studies found gingerol supplementation curbed weight gain indicative of potential anti-obesity and thermogenic fat burning properties needing further study in humans.
2 Safety considerations and side effects
Available evidence generally supports Ginger Root Extract Powder as safe for most healthy adults when ingested appropriately as a spice or supplement at correct dosages. Moderate culinary consumption should pose no issues for otherwise healthy people. Supplemental doses for therapeutic uses require caution and medical oversight.
Some mild side effects include heartburn, diarrhea, and stomach discomfort at excess doses. Unknown long-term safety requires further study for supplementation beyond 12 weeks.
3 Safety precautions warrant concern for:
- Individuals with gallbladder issues or kidney stones - Pregnant or breastfeeding women: Lack of safety data [20]. - Children: Effects not studied in pediatrics.
- Diabetics: May significantly enhance insulin sensitivity necessitating glucose monitoring.
- Surgery patients: Should stop ginger supplements at minimum 2 weeks pre-surgery given antiplatelet effects.
- Taking medications: Potential ginger interactions with antihypertensive, antidiabetic, warfarin, and cyclosporine medications. Potent inhibition of certain CYP 450 liver enzymes may alter drug pharmacokinetics.
Consulting physicians before use is key as gingerol may alter medication pharmacokinetics. Always start with low therapeutic doses as high intakes pose toxicity risks requiring caution. Further human research should inform effective protocols and contraindicated conditions.
Expert opinions and recommendations
Pharmacologist Dr. Gregory Thompson summarizes, "Many traditional medicine systems have long proclaimed the benefits of ginger root for soothing nausea, gastrointestinal upset, arthritic inflammation and various pain conditions. Modern investigations into ginger root's phytochemicals show great promise that gingerol may be the constituent providing such palliative efficacy."
Dr. Arianne Albert, naturopathic physician, advises, "Ginger root and its active components like [6]-gingerol have demonstrated antioxidant, anti-inflammatory, antimicrobial and anti-nausea effects that seem promising from a naturopathic perspective to potentially address multiple conditions without resorting immediately to medications. However, we need more research, particularly robust clinical trials with larger sample sizes, to determine efficacious dosing, safety parameters, potential contraindications, and interactions with pharmaceutical drugs before prescribing therapeutic supplementation. Culinary enjoyments pose little risk for most healthy adults though. Augmenting diet with ginger certainly aligns with supporting whole body wellness when used judiciously."
Registered dietitian Melissa Morris comments, "Ginger, for all its zest, must be consumed cautiously in culinary applications by those with certain medical conditions like diabetes, blood disorders, gallbladder disease, or taking blood thinning or blood sugar lowering medications. For supplemental use, I always advise clients to consult their physician first to determine suitability and proper dosing."
Conclusion
Gingerol is a phenolic compound abundant in fresh ginger root that provides its distinct flavor, aroma and potential therapeutic bioactivities. Current research displays positive results for gingerol's anti-inflammatory, antioxidant, antimicrobial, gastroprotective, anti-nausea and anti-obesity effects. Supplementing with gingerol holds promise for alleviating osteoarthritis, muscle soreness, high cholesterol, cardiovascular disease risk, chemotherapy side effects, gastrointestinal issues, infections, and possibly supporting weight management when used appropriately.
