biofilm growth stopped in the strongest result, in glassware
Laboratory study · Tested in a dish · Saudi Sumra honey
What they did
Saudi Sumra honey was tested by broth dilution against clinical isolates of bacteria and fungi, including methicillin-resistant Staphylococcus aureus. Biofilm formation, quorum sensing — the signalling bacteria use to coordinate — and antioxidant activity were measured, and the honey's composition was read by GC-MS.
What they found
- Minimum inhibitory concentration 300 mg/mL against S. aureus including MRSA, 250 against Pseudomonas aeruginosa, 350 against E. coli, 250 against Acinetobacter baumannii.
- Biofilm formation reduced by 59% for Bacillus subtilis, 48% for S. aureus, 38% for E. coli, 33.6% for P. aeruginosa.
- Antioxidant activity: DPPH IC50 7.7 mg/mL, ABTS IC50 5.4 mg/mL.
What this study does not show
- This happened in glassware. It is not a treatment, it was not tried in animals or people, and we do not present it as either.
- The concentrations are enormous — 300 mg/mL is roughly a third honey by weight, held against bacteria in a dish. Eating a spoonful is nothing like it.
- The honey was Saudi Sumra. Ours is Yemeni Sumra from Wadi Doan. Same tree, different ground.
- One sample, one laboratory, not replicated elsewhere.
Why we publish it
Most Yemeni-honey research is about Sidr. This is one of the few papers about Sumra, the honey Yemenis have always kept for the stomach.

What this page is. These are summaries of published research about honey as a substance. They are not claims about DIVINEDROP products. No DIVINEDROP honey diagnoses, treats, cures or prevents any disease. Honey is a sugar-rich food, it is not suitable for infants under 12 months, and anyone managing a health condition should speak to their doctor.
