Due to various medical reasons, patients often have a catheter fitted, and these flexible tubes can contain nasty bugs and cause infection.

Theoretically, water with honey might be useful for flushing urinary catheters to keep them clean while they remain in the bladder.
Scientists admit that so far many more trials would be needed to check whether it is safe to use this technology in humans.
