I did some tests regarding transdermal activity:

I cleaned very well with a rag full of DMSO.  I felt like i had flames on my body for a bit.  The i took a bath in Syrian Rue tea.  There is little to no transdermal activity – however sprinkling a few seeds in the bath appears intelligent.  They “cling” to you in certain spots and allow you to rub off a little something u didnt know was there.  I dont know if they are “grabbing” at something or “planting” themselves – they dont act like other seeds in the bath.  After the bath just to re-search – i painted myself in clove oil and the “flames” lasted 10 minutes.  I was sore the next day.  If i didnt try things, i wouldn’t discover things.
