Just read the paper (well, skimmed is more honest). They cite 5 human trials. The first study was not blind, and it also did not show a difference between the control group and the treatment group. The "mini-review" author made it seem like there was an improvement to the honey group over the control, but this was not the case.

The second study, I can't access. The conditions were a bit more complicated, so I can't fully assess, but the "mini-review" author notes that they were also treated with olive oil and corticosteroids. Also, the group sizes were tiny (11 people split into 3 groups), which makes me highly suspicious of any statistically relevant effects. There's also no placebo.

The third study seems legit from a quick skim. They placebo controlled with flavored corn syrup. At the end of the study, the treatment group does not have a significantly different symptom score than the placebo group. The fact that both groups improve is again misinterpreted by the "mini-review" author. In their defense, the authors of that third study really wordsmith their abstract to make it read that way.

The forth and fifth study both show no improvement due to the treatment.

So 4/5 studies show no improvement over control/placebo, and the 5th study i can't read.

I did find a randomized, controlled study on birch honey which seems good, and it shows an improvement over a regular honey control. That's not in the minireview.

Overall, if there's 4 studies saying no, 1 saying yes, and 1 inconclusive, I'm going to take that as a no.
