You are standing in a grocery aisle holding a $9 jar of local wildflower honey in one hand and a $38 jar of New Zealand manuka in the other. You've heard manuka is medicinal. You've heard raw is what matters. You've heard UMF 10+ is the minimum. You've also heard most of this from people who sell manuka honey.
Here's the actual story, based on what the research supports, and where the two kinds of honey overlap, diverge, and — in the specific case of sore throat and upper-respiratory symptoms — become roughly interchangeable.
What "raw honey" actually means
Raw honey is honey that has not been heated above hive temperature (roughly 95°F) and has not been filtered finely enough to remove pollen, propolis traces, and enzymes. Commercial honey, by contrast, is usually pasteurized at 160°F+ and ultrafiltered — which gives you a shelf-stable clear syrup that looks nice but has lost most of what makes honey biologically active.
The enzyme that matters most for antimicrobial activity is glucose oxidase. It produces small, steady amounts of hydrogen peroxide when honey touches moisture. Heat kills it. Ultrafiltration pulls out the pollen and micronutrients that come with it. What's left tastes fine on toast and does very little on your throat tissue.
What manuka is
Manuka is raw honey made by bees foraging on the manuka bush (Leptospermum scoparium), native to New Zealand and parts of Australia. It has everything any raw honey has — glucose oxidase, pollen, enzymes — plus a specific additional compound called methylglyoxal (MGO), which comes from the manuka nectar itself.
MGO is a non-peroxide antibacterial. Unlike the peroxide activity in regular raw honey, it's stable over time and at slightly higher temperatures. This is what the UMF (Unique Manuka Factor) rating is measuring — essentially, how much MGO is in the jar. UMF 10+ is the lower end of "medicinal grade"; UMF 20+ is where the prices get serious.
For wound care, there's a real and specific evidence base for medical-grade manuka — it's used in some burn and chronic-wound protocols. That's a legitimate application, and it's where manuka's reputation actually comes from.
What the sore-throat evidence actually shows
Here's where the marketing and the research diverge.
In 2020, Abuelgasim, Albury, and Lee at Oxford published a systematic review and meta-analysis in BMJ Evidence-Based Medicine: 14 studies, 1,761 participants, honey for upper-respiratory infection symptoms. Honey outperformed standard care for cough frequency, cough severity, and symptomatic relief.
Most of the studies in that meta-analysis used ordinary raw honey — pasteurized honey wasn't the comparator, and manuka-specific grades weren't the variable being tested. The underlying mechanism for sore-throat relief is coating, mild osmotic pull, low pH, and the hydrogen peroxide activity from glucose oxidase. Those are properties of any raw, unheated honey. Manuka has them too, plus MGO on top. But the MGO is not what's doing the throat work.
For sore throat, the evidence points to any raw, unheated honey. Manuka's specific value is somewhere else — in wound care, not your pharynx.
Where the price difference comes from
Manuka is expensive because it's geographically constrained (only grows in New Zealand and a narrow band of Australia), seasonally limited, rigorously tested, and strongly marketed. None of those factors make it better for a sore throat. They make it better for a burn dressing.
A good raw wildflower honey from a single US apiary — traceable, unheated, minimally filtered — carries the glucose oxidase activity, the pollen spectrum, the viscous coating, and the mild osmotic pull that the Oxford meta-analysis was measuring. At a fraction of the manuka price, and with a supply chain that doesn't involve air-freighting a condiment across the Pacific.
What we use, and why
The raw wildflower honey in our Box of 20 comes from a single US apiary. It's not heated during blending — we cold-mix it with the Atlantic sea salt specifically so the glucose oxidase stays intact. The ratio is 35% honey to 65% salt, which is where the coating effect of honey and the rinsing effect of hypertonic saline balance out in a way that actually reaches the back of the throat.
We didn't use manuka because we're not making a wound dressing. We're making a daily throat ritual.
What neither kind of honey will do
No honey treats strep throat. No honey replaces antibiotics for bacterial infections. Neither raw wildflower nor UMF 20+ manuka is an antiviral, and neither will prevent a cold you've already caught. Both are unsafe for infants under 12 months — the under-one honey rule applies to every kind.
And manuka, despite the pricing, is not inherently "stronger" for respiratory use. For wound care, yes. For the pharynx, the evidence says "raw honey, traceable source, unheated" and the brand of nectar the bees happened to find isn't the variable.
The practical answer
If you're buying honey to put on a burn under medical supervision, manuka is reasonable. If you're buying honey for tea, for a sore throat, or as one of the two ingredients in a daily gargle — a good raw wildflower honey from a traceable source, used cold, gives you everything the meta-analysis was measuring.
Save the $29. Pour. Stir. Gargle. Honey and salt. Nothing else.
