Drinking the milk of goats that eat poison

I wonder if it helps to be sensitized as a child to poison ivy (back
east) and then to be thoroughly exposed to poison oak (out west).

The only difference in the catechol oil urushiol is poison ivy urushiol
has a 15 carbon chain while poison oak urushiol has a 17 carbon chain.

But, slight differences, can sometimes make a huge difference in cell
mediated immune responses.

Note: I use free drillers bentonite instead of expensive ivy block; and I
use Dawn dishwashing liquid instead of $40/ounce Technu (only the
government can afford those prices!).

BTW, here's a dripping vine I cut today, the size of my wrist, just
dripping with urushiol!
