Sorry, I'm not sure if that statement is correct. The elemicin SWIM had was not 100% pure. It was 91% I think. I don't know what the impurities were; they could have been responsible for the stronger odor. Also SWIM never had pure eucalyptol, but rather eucalyptus oil, so don't take that statement as a fact. Before that can be said as a fact, SWIM has to have 100% pure elemicin and 100% pure eucalyptol for comparison.
