(A) The graph presents the percentage of viable cells and thus toxicity of the three MTS tests performed on human keratinocyte cells (HaCaT), with dose dependent killing up until 16 µg/mL of CBD, from where the toxicity levels out around 50% up to the highest tested concentration of 64 µg/mL of CBD. (B) CBDA and CBD demonstrate very minor hemolytic activity in concentration ranges of up to around 8 × MIC and 4 × MIC, respectively. SDS was used as a positive control lysing 100% of the red blood cells.
