What propolis actually does, by outcome

Each row is one outcome with effect size, evidence base, the dose that worked in trials, and time to first effect. Magnitude tiers come from native-unit MCID where available, Cohen's d otherwise.

Forms & standardisation

Topical forms own the evidence. Look for propolis mouthwash, gel, spray, or lozenges, and label language like propolis extract or standardized propolis, because that is what the oral trials actually tested.¹² Capsules show up on shelves, but the best human data for gums and canker sores comes from products that touch the mouth directly.¹²

Frequently asked

Common questions

Does propolis help bleeding gums?

Early oral-health trials show propolis improves gum inflammation and bleeding, especially in topical forms used for a few weeks.¹ The signal looks real, but the evidence still needs bigger confirmation.

Is propolis good for canker sores?

Small human studies show faster healing and fewer flare-ups of canker sores with propolis.² The data is promising, but it is still thin.

What form of propolis works best for mouth problems?

The best-studied forms are the ones that touch the mouth directly, like mouthwash, gel, spray, or lozenges.¹² Capsules exist, but the oral-health evidence mostly comes from topical use.

Is propolis safe if you have bee allergies?

Skip propolis if bee products or hive materials trigger you, because hypersensitivity reactions show up in the safety literature.⁴ That caution matters more if you already react to pollen, bee stings, or honey-based products.
