A ginger drink can match the trial dose, but no trial we read tested tea. In capsules, 0.5 to 3 grams of ginger a day for up to 3 months was the range reported to work. Across 29 randomized trials, ginger lowered CRP, a blood marker of inflammation, by a small 0.86 mg/L.
Can a ginger drink lower inflammation?
Start with what the research measured. CRP (C-reactive protein) is a protein your liver makes more of when inflammation is up. A meta-analysis pools many trials into one answer.
The largest one so far, from 2025, pooled 29 randomized trials of ginger supplements. CRP fell by 0.86 mg/L on average. Two signals that immune cells use, IL-6 and TNF-alpha, fell too. An earlier meta-analysis of 16 trials with 1,010 people found lower CRP and TNF-alpha, but no clear change in IL-6. In five trials of people with type 2 diabetes, the drop was real but "relatively small."
So the direction is steady. The size is modest.
And here is the catch for anyone holding a mug. A 2020 review of 109 ginger trials found only 43 of them met its bar for high-quality evidence, and it flagged small groups and unstandardized methods. The umbrella review said the same thing in plainer terms: trials described their ginger poorly. Not one of these papers tested a cup of tea.
The dose that was tested
We pulled the doses from the trials in our pack into one table, so you can see what people actually swallowed.
Two grams of dried ginger a day was the dose the 12-week colitis trial used.From a 2019 randomized trial in Complement Ther Med
| Study | Who | Daily dose | How long | What changed |
|---|---|---|---|---|
| Crichton 2022 | 24 reviews of many trials | 0.5 to 3 g, in capsules | Up to 3 months | The range "consistently reported as effective" |
| Nikkhah-Bodaghi 2019 | Forty-six adults with mild to moderate ulcerative colitis | 2,000 mg dried ginger powder, as 4 capsules | 12 weeks | Disease activity and quality of life improved; a marker of cell damage (MDA) fell by week 6 |
| Hu 2011 | 11 adults with indigestion (functional dyspepsia) | 1.2 g, as 3 capsules, once | One test day | Stomach emptied faster; symptoms did not change |
| Broeckel 2025 | 30 adults with joint and muscle pain | 125 mg of extract (12.5 mg gingerols) | 58 days | Some inflammation markers moved; pain and stiffness ratings improved |
Do the math on the colitis trial: 2,000 mg split across 4 capsules is 500 mg, or half a gram, per capsule. That is a small amount of powder. Spread over a day, it fits easily in two mugs of hot water.
One honest limit. Every trial here measured dried ginger or an extract. These papers give no way to convert grams of dried powder into grams of fresh root, so our plan sticks with dried, ground ginger.
Does ginger reduce inflammation in the gut?
The best gut trial we found was in ulcerative colitis, a bowel disease driven by inflammation. Forty-six people with mild to moderate disease took 2 grams of dried ginger a day or a placebo for 12 weeks. By the end, the ginger group's disease activity scores were better, and so was their quality of life. That is one small trial, so treat it as a lead.
Ginger also seems to move the stomach along. In 11 people with indigestion, 1.2 grams in capsules made the stomach empty faster, from a median of 16.1 minutes to 12.3. Their symptoms did not change.
How to tell if it's working
You won't feel your CRP. If you want a number, an hs-CRP blood test before you start and again after 12 weeks is the only way to see it, and your doctor can order both. Keep your expectations small: the average drop across 29 trials was 0.86 mg/L.
Pain is easier to track. The joint pain trial checked people at day 0, day 30 and day 56, and ratings of pain, stiffness and daily function improved. Rate your own aches from 0 to 10 on day 1, then at weeks 4 and 8.
Could ginger make inflammation worse? In the meta-analyses we read, markers went down or did not change. None went up. One trial did see a rise in eosinophils, a type of white blood cell, in the ginger group.
Who should skip it
Skip it if ginger has ever given you a rash, swelling or trouble breathing. Stop if it upsets your stomach.
Ask first if you take a blood thinner. A systematic review of 8 clinical trials found that 4 reported ginger made platelets, the cells that start a clot, clump less, and 4 found no effect. The authors called the evidence equivocal. Ask first, too, if you take medicine for blood sugar, since glycemic control is one of the areas where ginger showed effects. The trials here enrolled adults, so this plan is not for children.
The plan
Tick what you'll try this week. Your picks stay on this device.
you take a blood thinner or aspirin, take medicine for diabetes, are pregnant or breastfeeding, have gallbladder or bleeding problems, have surgery coming up, or want to give ginger to a child. Keep taking your medicine as prescribed and talk to your provider before changing it.
