A small jar of this sticky stuff can cost anything from around ten pounds to over a thousand. Some brands claim it can help with sore throats, skin problems, hay-fever and poor sleep. Other producers curiously make no health claims at all about their manuka products. So what’s the buzz about and is there any science behind it?

Listener and beekeeper David got to get in touch to ask whether manuka honey can boost the immune system, and if it has any benefits over and above the ordinary honey from his bees produce.

Greg Foot gets stuck in to find out, talking with two microbiologists to learn why manuka honey is different and if there’s any truth to some of those sweet sounding claims.
