Koromiko's traditional medicinal reputation belongs to the leaf, not to the honey.
Māori medicinal use of koromiko is documented for the leaf and leaf-bud, prepared as an infusion or chewed, principally for diarrhoea and stomach complaints. It was supplied to New Zealand troops for this purpose in both world wars. There is no corresponding traditional or evidential basis for the honey having the same effect, and the two should not be conflated.
