adifrank Posted February 6, 2006 Share Posted February 6, 2006 I hope I'm asking this question in the right forum. If not, please redirect me. Anyway, my question is: when we smell aromatic cedar, what is the size range in microns of the particle(s) that are actually physiologically interacting with our systems? .... Don't ask why I need to know. Thanks for your help!! Link to comment Share on other sites More sharing options...
DV8 2XL Posted February 6, 2006 Share Posted February 6, 2006 The active component of cedar's odor is an aromatic essential oil called lignen, I believe - a medium sized molecule Link to comment Share on other sites More sharing options...
