Ginger and honey each trigger a surprisingly wide range of physiological responses, from dampening nausea signals in the gut to lowering inflammatory markers in the blood. Together, they share overlapping anti-inflammatory and antimicrobial properties, and lab research suggests their combination can amplify certain effects beyond what either produces alone. The pairing is more than folk-remedy tradition: peer-reviewed studies back several of the claims people make about this duo, though some effects are better established than others.
How Ginger Calms the Stomach
The most thoroughly studied benefit of ginger is its ability to reduce nausea and vomiting. The active compounds responsible, mainly gingerols and shogaols, work by blocking serotonin receptors (specifically the 5-HT3 type) in the gut and brain. These are the same receptors targeted by prescription anti-nausea drugs. Ginger compounds also antagonize substance P and acetylcholine receptors, and they speed up the rate at which the stomach empties, all of which contribute to settling queasiness.1PubMed. Ginger-Mechanism of action in chemotherapy-induced nausea and vomiting: A review Lab studies on gut tissue confirm that gingerols and shogaols weakly inhibit both muscarinic and serotonin receptors involved in intestinal contractions, which helps explain why ginger eases cramping and not just the urge to vomit.2PubMed. Effects of ginger constituents on the gastrointestinal tract: role of cholinergic M3 and serotonergic 5-HT3 and 5-HT4 receptors
This anti-nausea effect holds up across different contexts. Clinical trials have tested ginger for morning sickness, motion sickness, post-surgical nausea, and chemotherapy-induced nausea, and while the strength of evidence varies, the direction is consistently positive. For the average person dealing with an unsettled stomach after a meal or during travel, ginger tea or a small piece of candied ginger root is one of the better-supported home remedies available.
Honey for Coughs and Upper Respiratory Infections
Where ginger’s headline act is nausea relief, honey’s strongest clinical showing is against coughs and sore throats. A systematic review and meta-analysis pooling data from multiple trials found that honey outperformed usual care for upper respiratory infections. It reduced cough frequency, cough severity, and overall symptom scores compared with standard treatments or no treatment.3PubMed. Effectiveness of honey for symptomatic relief in upper respiratory tract infections: a systematic review and meta-analysis The effect is meaningful enough that some medical guidelines now recommend honey as a first-line option for cough in adults and children over one year old, before reaching for over-the-counter cough suppressants.
The mechanism is partly physical: honey coats and soothes irritated throat tissue. But its antimicrobial and anti-inflammatory properties likely play a role too, reducing the bacterial load and local swelling that drive persistent coughing. Pairing honey with ginger in a warm drink is a classic combination, and while no large trial has tested the precise pairing for colds, the logic holds up given that ginger contributes its own anti-inflammatory effects and honey handles the cough directly.
Dialing Down Inflammation
Chronic, low-grade inflammation is implicated in everything from joint pain to heart disease, and both ginger and honey contain compounds that interfere with inflammatory signaling. For ginger, the key pathway involves a protein complex called NF-κB, which acts as a master switch for inflammation. When immune cells encounter a threat, NF-κB turns on and triggers the release of inflammatory molecules. Gingerol suppresses NF-κB activation, which in turn reduces the production of several pro-inflammatory signals including TNF-α, IL-1β, and IL-6.4PubMed. Anti-Inflammatory Effects of Gingerol on Lipopolysaccharide-Stimulated RAW 264.7 Cells by Inhibiting NF-κB Signaling Pathway The same pattern has been observed with 6-gingerol in macrophages specifically, where it blocked the inflammatory cascade triggered by bacterial toxins without interfering with other immune functions.5Frontiers in Immunology. The “root” causes behind the anti-inflammatory actions of ginger compounds in immune cells
Among ginger’s family of active compounds, the shogaols appear to be the more potent anti-inflammatory agents. In a mouse model of intestinal inflammation, 10-shogaol was the most effective compound tested, outperforming both gingerols and shorter-chain shogaols, all through the same NF-κB pathway.6Heliyon. Anti-inflammatory effect and signaling mechanism of 8-shogaol and 10-shogaol in a dextran sodium sulfate-induced colitis mouse model Shogaols form when ginger is dried or cooked, which means dried ginger powder or a long-simmered ginger tea may deliver a somewhat different anti-inflammatory profile than fresh ginger slices.
Honey contributes its own anti-inflammatory activity through its polyphenol content. While the evidence for honey’s systemic anti-inflammatory effects is less extensively studied than ginger’s, one trial in healthy, diabetic, and hyperlipidemic subjects found that honey consumption for 15 days reduced C-reactive protein, a major blood marker of inflammation, by about 7% in healthy subjects and 75% in those with high cholesterol.7PubMed. Natural honey lowers plasma glucose, C-reactive protein, homocysteine, and blood lipids in healthy, diabetic, and hyperlipidemic subjects: comparison with dextrose and sucrose
Blood Sugar and Cholesterol
Ginger has shown a consistent ability to improve blood sugar control in people with type 2 diabetes. A meta-analysis of randomized controlled trials found that ginger supplementation significantly reduced fasting blood sugar, lowered HbA1c (the measure of long-term blood sugar control), and improved insulin sensitivity compared with placebo.8PubMed Central. Effects of Ginger (Zingiber officinale Roscoe) on Type 2 Diabetes Mellitus and Components of the Metabolic Syndrome: A Systematic Review and Meta-Analysis of Randomized Controlled Trials A more recent meta-analysis confirmed the direction, reporting a significant reduction in both fasting blood sugar and HbA1c across eight and seven study arms respectively.9Complementary Therapies in Medicine. The effect of ginger supplementation on metabolic profiles in patients with type 2 diabetes mellitus: A systematic review and meta-analysis of randomized controlled trials In one individual trial, people with type 2 diabetes who took ginger powder daily saw roughly a 10% drop in fasting blood sugar over the study period, while the placebo group’s blood sugar actually rose.10PubMed. The effect of ginger powder supplementation on insulin resistance and glycemic indices in patients with type 2 diabetes: a randomized, double-blind, placebo-controlled trial
Honey’s relationship with blood sugar is more nuanced, because it is, after all, largely sugar. But compared with table sugar or glucose syrup, honey produces a smaller blood sugar spike and has been associated with modest improvements in lipid profiles. A large meta-analysis of 29 trials found that oral honey intake lowered total cholesterol, LDL cholesterol, and triglycerides while raising HDL cholesterol.11Nutrition Reviews. Effect of honey on cardiometabolic risk factors: a systematic review and meta-analysis In healthy young subjects, honey consumption improved the lipid panel across the board, while an equivalent amount of sucrose pushed cholesterol and triglycerides in the wrong direction.12Clinical Nutrition ESPEN. Effect of natural honey consumption compared with sucrose on lipid profile among young healthy subjects The mechanism likely involves honey’s polyphenols and its lower glycemic effect relative to refined sugars, but honey is still calorie-dense, so these benefits apply to moderate use, not unlimited consumption.
Blood Pressure
A recent dose-response meta-analysis of randomized controlled trials found that ginger supplementation lowered systolic blood pressure by about 5 mmHg and diastolic blood pressure by about 2 mmHg on average. The largest effects appeared in people who already had elevated blood pressure, those taking doses of 2,000 mg per day or more, and those with obesity.13PubMed Central. Ginger Supplementation and Blood Pressure in Adults: A GRADE-Based Systematic Review and Dose-Response Meta-Analysis of Randomized Controlled Trials Animal research offers a plausible mechanism: ginger extract relaxes blood vessels through multiple routes, including stimulation of muscarinic receptors and blocking of calcium channels, a dual action that echoes how some pharmaceutical blood-pressure drugs work.14Vascular Pharmacology. Cardiovascular effects of ginger aqueous extract and its phenolic constituents are mediated through multiple pathways A 5-point systolic drop is not dramatic compared with medication, but for someone making lifestyle changes and looking for small edges, it is meaningful.
Menstrual Pain Relief
One of the more practical findings about ginger is its effect on menstrual cramps. A meta-analysis of five placebo-controlled trials found that ginger was significantly better than placebo at reducing period pain severity.15PubMed Central. Efficacy of Ginger in the Treatment of Primary Dysmenorrhea: A Systematic Review and Meta-analysis Two additional trials compared ginger head-to-head with ibuprofen-type painkillers and found them equally effective.16Pain Medicine. Efficacy of Ginger for Alleviating the Symptoms of Primary Dysmenorrhea: A Systematic Review and Meta-analysis of Randomized Clinical Trials In one randomized trial, the ginger group reported about 11 fewer hours of pain and rated their pain roughly 3 points lower on a 10-point scale than the placebo group.17PubMed Central. Effect of Zingiber officinale R rhizomes ginger on pain relief in primary dysmenorrhea a placebo randomized trial The effective doses in these studies generally ranged from 750 to 2,000 mg of ginger powder per day during the first three to four days of the menstrual cycle.
Antimicrobial Effects and the Ginger-Honey Combination
Honey’s germ-fighting ability is well documented. Multiple components contribute: its high sugar concentration draws water out of bacterial cells, hydrogen peroxide generated by an enzyme in honey damages microbial DNA, polyphenols disrupt bacterial membranes, and a peptide called bee defensin-1 attacks bacteria directly. These elements work together, making honey active against a range of pathogens including drug-resistant strains.18PubMed Central. The antibacterial activities of honey Hydrogen peroxide plays a central role, but its concentration in honey is far lower than in medical disinfectants. Other honey components amplify its effect: DNA damage in bacteria occurred at hydrogen peroxide concentrations lower than expected, pointing to a cooperative effect among honey’s constituents.19PubMed Central. Re-examining the role of hydrogen peroxide in bacteriostatic and bactericidal activities of honey
When ginger extracts are mixed with honey, the antibacterial effect becomes greater than either ingredient alone. One study testing honey-ginger mixtures against both standard and drug-resistant bacteria found that the combination produced the largest zones of bacterial inhibition, exceeding the performance of honey alone, ginger alone, and even several common antibiotics like methicillin and amoxicillin tested against resistant strains.20PubMed Central. Synergetic Antimicrobial Effects of Mixtures of Ethiopian Honeys and Ginger Powder Extracts on Standard and Resistant Clinical Bacteria Isolates A separate study of bacteria from decayed teeth in orthodontic patients reached a similar conclusion about the synergistic antimicrobial effect of the combination.21Asian Pacific Journal of Tropical Biomedicine. Antimicrobial activity of ginger and honey on isolates of extracted carious teeth during orthodontic treatment These are lab findings rather than clinical trials in sick people, so they do not prove that drinking ginger-honey tea will cure an infection, but they do show a genuine biological mechanism behind the traditional use.
What Honey Does for Gut Bacteria
Beyond killing harmful microbes, honey also appears to feed the beneficial ones. Honey contains non-digestible oligosaccharides, short chains of sugar molecules that pass through the upper digestive tract intact and become food for bacteria in the colon. Lab studies show that honey oligosaccharides increase populations of bifidobacteria and lactobacilli, two groups widely considered beneficial, though not quite as strongly as commercial prebiotic supplements like fructo-oligosaccharides.22PubMed. In vitro investigation into the potential prebiotic activity of honey oligosaccharides Several reviews of in vitro, animal, and early human studies have found that honey selectively encourages the growth of Lactobacillus and Bifidobacteria while inhibiting potentially harmful species like Salmonella, E. coli, and C. difficile.23PubMed Central. The Potential of Honey as a Prebiotic Food to Re-engineer the Gut Microbiome Toward a Healthy State The oligosaccharide content varies widely by honey type, so not every jar at the store will have the same prebiotic punch.24Food Quality and Safety. Effect of honey in improving the gut microbial balance
Thermogenesis, Appetite, and Weight
Ginger appears to slightly increase the amount of energy your body burns after eating, an effect called diet-induced thermogenesis. A crossover trial in overweight men found a modest but statistically significant boost in the thermic effect of food with ginger, along with reduced hunger and a lower desire to eat, even though hormones like leptin and ghrelin did not change significantly.25PubMed Central. Ginger consumption enhances the thermic effect of food and promotes feelings of satiety without affecting metabolic and hormonal parameters in overweight men: A pilot study A separate crossover trial estimated that ginger tea increased non-nitrogen energy expenditure by roughly 113 kcal per day compared with water, though in that study appetite ratings did not differ.26Food Bioscience. Ginger infusion increases diet-induced thermogenesis in healthy individuals: A randomized crossover trial These are small, short-term studies, and an extra hundred calories of burn per day is modest. Nobody should expect ginger to replace exercise or a balanced diet, but it may provide a minor metabolic nudge.
Honey, meanwhile, compares favorably to table sugar in at least one appetite-related measure. When people ate a meal sweetened with honey instead of sucrose, the ghrelin response (the “hunger hormone” signal) was delayed and a fullness-promoting hormone called PYY was elevated more strongly. Blood sugar also rose less sharply after the honey meal. However, the two meals produced no difference in actual calorie intake afterward.27PubMed. Effect of honey versus sucrose on appetite, appetite-regulating hormones, and postmeal thermogenesis The takeaway is that honey is a marginally smarter sweetener than refined sugar from a metabolic standpoint, but it is not a weight-loss tool on its own.
Wound Healing and Tissue Repair
Applied topically, honey has a well-documented role in wound care. Medical-grade honey products are used in hospitals for burns, surgical wounds, and chronic ulcers. Honey promotes tissue repair through a combination of its antibacterial properties, its ability to maintain a moist wound environment, and its anti-inflammatory activity, which together reduce infection risk and support new tissue growth.28PubMed Central. Honey, Wound Repair and Regenerative Medicine Manuka honey, a monofloral variety from New Zealand, has received particular attention for wound applications because of its unusually high concentration of the antibacterial compound methylglyoxal.29PubMed. Health Benefits of Manuka Honey as an Essential Constituent for Tissue Regeneration This is a topical application rather than a dietary one, so it falls outside the “what does eating ginger and honey do” frame, but it is worth knowing if you have minor cuts and a jar of raw honey in the pantry. Regular grocery-store honey has not been sterilized for wound use, so medical-grade products are preferable for anything beyond very minor scrapes.
Oxidative Stress
Both ginger and honey contain antioxidant compounds, and there is some evidence that the combination addresses oxidative stress more effectively than either ingredient alone. In diabetic rats, a combination of gelam honey and ginger significantly reduced markers of oxidative damage (including MDA, a byproduct of cell membrane damage) while boosting glutathione, the body’s primary internal antioxidant.30PubMed Central. Effect of the combination of gelam honey and ginger on oxidative stress and metabolic profile in streptozotocin-induced diabetic Sprague-Dawley rats A separate animal study found that ginger honey administration raised glutathione levels significantly.31Gaceta Sanitaria. Ginger honey affects cortisol, estrogen and glutathione levels; preliminary study to target preconceptional women These are animal and preliminary findings, so it would be premature to claim specific antioxidant benefits in humans, but they point toward a plausible mechanism for some of the metabolic improvements seen in clinical trials.
How Your Body Processes Ginger Compounds
Understanding how ginger is metabolized helps explain why the form you consume matters. After you eat ginger, 6-gingerol is partly converted to 6-shogaol and zingerone. The conversion to shogaol is largely one-directional: gingerol turns into shogaol much more readily than the reverse, and both compounds are cleared fairly quickly.32Frontiers in Pharmacology. Unraveling the interconversion pharmacokinetics and oral bioavailability of the major ginger constituents: [6]-gingerol, [6]-shogaol, and zingerone after single-dose administration in rats In human blood after ginger consumption, roughly a third of 6-gingerol ends up as its reduced metabolites (gingerdiols), while over 90% of 6-shogaol gets converted into phase I and cysteine-conjugated metabolites.33PubMed Central. Pharmacokinetics of Gingerols, Shogaols, and Their Metabolites in Asthma Patients These metabolites themselves appear to be bioactive, so the health effects of ginger are not solely about the parent compounds you swallow. Cooking, drying, and fermenting ginger all shift the ratio of gingerols to shogaols, which is part of why dried ginger and fresh ginger can have somewhat different effects in the body.
Safety Considerations
Ginger is generally safe in the amounts used in food and in typical supplement doses up to about 2 to 4 grams of dried ginger per day. However, because ginger has mild anti-platelet activity, there have been concerns about interactions with blood-thinning medications. A case report documented a probable interaction between ginger and the anticoagulant phenprocoumon, resulting in excessive anticoagulation.34PubMed. Ginger-associated overanticoagulation by phenprocoumon On the other hand, a controlled study in healthy volunteers found that ginger did not affect the blood-thinning action of warfarin, nor did it change platelet aggregation or warfarin clearance.35PubMed Central. Effect of ginkgo and ginger on the pharmacokinetics and pharmacodynamics of warfarin in healthy subjects The contradiction suggests the interaction may depend on dose, individual metabolism, or the specific anticoagulant involved. If you take blood thinners, mentioning your ginger intake to your doctor is a reasonable precaution, but casual ginger tea consumption is unlikely to cause problems for most people.
For honey, the main hard safety rule is age-related: honey should never be given to infants under 12 months old. Honey can harbor spores of Clostridium botulinum, the bacterium responsible for botulism. An infant’s immature gut allows those spores to germinate and produce toxin, which can cause a life-threatening illness. Documented cases of infant botulism traced directly to honey ingestion confirm this is not a theoretical risk.36PubMed Central. Infant botulism following honey ingestion For older children and adults, the mature digestive system prevents the spores from causing problems. People with diabetes should also be mindful of honey’s sugar content; the metabolic advantages over table sugar do not make it a free pass for unrestricted use.
