Poison oak, poison ivy & and poison sumac all contain the same allergenic oil, urushiol.
There was one experiment (not a clinical study) where a researcher rubbed leaves of poison oak, ivy & sumac on the backs of volunteers. The rashes on each volunteer were all about the same.


You cannot tell the difference between a poison ivy rash, a poison oak rash and a poison sumac rash.

The yellow yuck is the clear plasma from your blood stream. The blisters have thin skins and break easily. Chemicals, including histamine cause the plasma to continue to seep out, so the area continues to drip, making a huge mess.


Sometimes this is all the rash that shows up, but often, it keeps getting worse until it resembles the rash on the right.

You can never tell how long a poison ivy rash, or poison oak rash will last, but often it takes a week to get worse, and a week to heal.
It looks like the blisters near the ankle have crusted over and the rash is on the downturn swing

Think you need to get better at identifying poison oak & poison ivy?
The first chapter of the book has been made into a booklet.
You can download for free on the home page and take it with you in the field.
You will be able to postively identify poison oak & poison ivy, and rule out look-a-likes, and prevent a poison oak rash or a poison ivy rash.

This rash is relatively new, because the blisters are fresh and full. Soon they will burst.
There is no allergenic oil in the bliosters, so when it leaks onto the skin, it cannot spread the rash.

You can keep this from happening to you. Go to the home page and check out some text from the book.

It's lots of fun to read.

Fingers often get poison oak and poison ivy rashes, beause we might have accidentally grabbed a branch, but the rash is usually not real bad. The palm side or soles of the feet almost never develop a rash.
Tough skin doesn't allow the allergenic oil to be easily absorbed.


It looks like this woman scratched her face with three fingers that were contaminated with the poison oak or poison ivy allergenic oil.
It would help if the oil was a bright color, so we could spot it on our skin.

The face is one of the worse places to have a poison oak or poison ivy rash. You just feel crappy.

Delicate skin areas like armpits, inside forearms, between upper legs, behind knees etc., allow more oil to be absorbed through the skin than tougher skin areas like the outside of the forearms.
After a serious rash, it seems that the sensitive skin areas often break out during succeding rashes without having been contaminated.
