Your addition was at one point too specific and at the other too vague.

Adding "particularly Scotland" is too specific since it is widely used wherever it grows.

The other bit, the ash circle doesn't "have to be" activated by a human - It's not part of a ritual, Scott and the others simply can't handle the substance and so Mrs. McCall had to lay down that final line in the doorway.

We don't know, for example, if Lydia or Kira could touch it. The Darach could touch it and she had stopped being human a long time before.

I hope that's clear enough for you.
