What It Actually Is
Manuka Honey is produced by bees foraging on the Manuka bush, native to New Zealand. It's graded by its Methylglyoxal (MGO) content, with MGO-400+ indicating a moderately high potency grade.
What Research Generally Shows
Manuka Honey has a well-established traditional and modern use for soothing throat irritation, with some research also examining its antibacterial properties due to its MGO content.
The Honest Gap
BreathEaseX doesn't disclose the amount of Manuka Honey per spray, though the MGO-400+ grade tells you its concentration standard.
