Lemon-Ginger-Honey Tea for Colds: Claims Checked

The claim

The claim is that a hot drink of lemon, ginger and honey helps a cold, soothes a cough or sore throat, or "supports immunity". We label the claim itself a marketing claim and a folk belief, and looked at what the evidence says for each part. The ginger plant is covered in Ginger and the single-herb tea in Ginger Tea.

What the NHS says

The NHS lists hot lemon and honey as something you could try for a cough and says it "can have a similar effect to cough syrup", but also says there is limited evidence that hot lemon and honey or herbal medicines ease a cough. [1] The NHS says a cough usually clears up by itself within 3 to 4 weeks. [1]

The hot drink

In a 2008 study of 30 people with a cold or flu, a hot fruit drink did not change objective measures of nasal airflow but did improve how people rated airflow. [4] The hot drink gave immediate and sustained relief from runny nose, cough, sneezing, sore throat, chilliness and tiredness, whereas the same drink at room temperature relieved only runny nose, cough and sneezing. [4] The authors discuss placebo effects and effects on saliva and airway secretions. [4] The abstract calls it a hot fruit drink and does not describe a lemon-ginger-honey tea, so the result should not be transferred to one.

Honey

• Cochrane review (2018): six randomized trials involving 899 children aged 12 months to 18 years. Honey probably reduces cough frequency better than no treatment or placebo (moderate certainty), and honey given for up to three days probably worked better than placebo. [5] The review concluded there was no strong evidence for or against using honey, and most children received treatment for one night. [5]
• Meta-analysis (2021): 14 studies of honey for upper respiratory tract infections found honey superior to usual care, and called for further high quality, placebo-controlled trials. [7]
• One trial: 300 children aged 1 to 5 years with colds and nighttime cough got a single dose of 10 g of honey or a date-extract placebo 30 minutes before bed. Parents rated the honey products higher for relief. [8]
• Form matters: the trial descriptions we read give honey on its own or in a syrup, and do not mention honey stirred into hot tea. [5][8] More on this is in Honey for Cough and Sore Throat and Honey.

Ginger

• Traditional use: NCCIH says ginger has been used in folk medicine for conditions such as asthma, flu, indigestion and gastrointestinal discomfort. [9]
• Research: NCCIH says most ginger studies tested dietary supplements rather than foods, and that ginger may help nausea and vomiting in pregnancy. It describes ginger as promoted for nausea and vomiting, osteoarthritis, menstrual cramps and other conditions, and does not name colds. [9]
• EU regulator (2025): the HMPC monograph lists a traditional use for relief of symptoms of the common cold, "exclusively based upon long-standing use". [6] The amounts it describes are for powdered ginger and tinctures, and tea is not among the forms it lists. [6]
• Cell study (preclinical): a hot-water extract of fresh ginger reduced plaque formation by human respiratory syncytial virus in cultured airway cells, while dried ginger did not show a dose-dependent effect. [10] This is a cell result, so it does not show that drinking ginger tea treats an infection.

Lemon

Proper evidence not found for lemon or lemon juice as a cold treatment. We searched PubMed for "lemon juice common cold" and "lemon ginger honey cold". Results were unrelated. For the vitamin C question, see Vitamin C and the Common Cold and Lemon Water: Claims Checked.

What you can safely do

• Do not give honey to a baby under 12 months.
• If you take a blood thinner, ask a pharmacist before using ginger regularly.
• Check the label if you buy a ready-made blend, since it may hold other herbs. See Herbal Tea Claims Checked.
• See a clinician if a cough lasts more than 3 weeks, if you are losing weight for no reason, if you have a weakened immune system, or if you have chest pain, trouble breathing or cough up blood. [1]
