I really dont know if any organic honey will work, you have to be sure the bees are feed on flowers/ flora and not on Sugar syrup as some bee keepers are dodgy and want more honey so they feed bees on all kinds of stuff, i would try to source honey your sure the bees are free to get to natural environment and if there is any activity rating its much better, try to source honey from mountain areas if possible.
manuka is online as well Tasmanian jelly bush or jarrah honey from Australia,
try the organic honey and see how it goes, the better honey is the darker and richer its color will be.
remember to mix in warm water and drink whole cup 3 times on empty stomach.
I am sorry i cant help u further as i am not an expert on honeys i must admit.
