Sorry if I'm sounding quite naive but I'm really yet to get it.
If I may get you right, human subjects with wounds were used as your treatment group. If that's the case, I don't see the relevance of using humans without wounds as control. The right thing, I stand corrected, would have been to compare the healing potency with conventional treatment excluding the honeys.
The patients with wounds should have been divided into 2 groups, exposed to the same treatment while the treatment group is given honey in addition. Then, the healing can now be compared after a chosen period.
No no no, @gentleshaid I think my explanation at the latter ending was not clear enough.
Human subjects with wounds were used as control obviously... probably the Way I constructed the English here got you confused.
