Table 3.

Effective concentrations values, EC₀₅ and EC₅₀ (% v/v), resulting from dose-response curves for the three honeys on A431 cells at 24 h.

Honey	EC05	EC50
Acacia	2.36% (1.68–3.32%)	5.84% (5.33–6.39%)
Buckwheat	1.05% (0.67–1.69%)	3.78% (3.41–4.19%)
Manuka	0.66% (0.48–0.92%)	2.59% (2.36–2.85%)

Experiments were performed by the Calcein-Am method in triplicate with a minimum of eight replicates each. 95% CIs are indicated in parenthesis. Am, acetoxymethylester; CI, confidence interval; EC, effective concentration.
