When eight male volunteers were exposed to air concentrations of 10, 225 or 450 mg/m3 of 97% pure (+)-limonene during light physical exercise, mean respective capillary blood concentrations were 1.5, 11.0 and 21.0 μmol/L after one hour, and 1.5, 12.5 and 23 μmol/L after two hours. In two similarly constructed studies, the human pulmonary uptake was ~ 60% for inhaled α-pinene, and ~ 70% for δ-3-carene at the two higher doses. The mean biofilm formation and inhibition value in the presence of essential oils was equal to 67±5.5% and 60% for P. aeruginosa MU 188. Chemotypes are variants within a single botanical species, but in other cases, such as calamus or sage, a difference in botanical origin also entails significant compositional differences with important toxicological consequences.
