Hi emily, there are a lot of places selling Manuka Honey , different grades, etc. mind boggling. i asked the doc, his reply is if you try enough honey, you will roughly know what are the good type. its different in taste and consistency. <gulp, vague eh>
i bought mine from Taka basement, outside the cold storage where there is different stalls selling chocs, tea, honey,etc. that's not bad. 3 of us share a bottle of 500g, each a teaspoonful on its own every night. now i am trying out another brand which i bot from Unity pharmacy.
i read that for toddlers, should get no more than umf 10 manuaka. if you are buying with UMF, do remember to look out for UMF 10 label, made in NZ. coz its quite misleading a lot of brands try to pass that off with varied labels. quite a bit of internet writeup on this which you can prob google for details...
