VOLUNTEERS WHO
HAVE HAD A DISABLING REACTION TO POISON-OAK SHOULD GENERALLY AVOID ANY
EXPOSURE.
Chronic health changes occasionally
occur following poison-oak exposure.
Half of Californians haven't had a reaction to poison-oak.
80% of these "non-reactors" develop a rash if adequately
provoked. Once provoked, you are allergic the rest of your
life. Being a non-reactor is convenient, but don't push
your luck!
If you are one of those who have had a reaction, take
comfort in knowing that the longer you go without having
another reaction, the less allergic you will become. With a
little bit of luck and skill, you'll be able to do what you
want!
Frequently Encountered Serious Problems:
(1) Oils
in the smoke from burning poison-oak can cause rashes on
exposed skin, especially at chafe points. Less commonly,
people have trouble breathing after exposure to the smoke.
(2) Punctures
and scratches by poison-oak require immediate first aid. Rinse
the wounds with drinking water; blot them dry; apply
bacitracin/polymixin ointment, available over-the-counter; and
bandage.
(3) Poison-oak leaves are more fragile than stems. The
sap from one poison-oak leaflet is sufficient to cause a rash
in a quarter of people.
(4) The sap from cut roots can get you. Roots
extend up to 25 feet from the nearest plant.
Other Concerns That Can Be Anticipated
(1) Permanent black clothing stains. Sometimes these clothes
are wearable; other times they provoke a reaction, despite
laundering, and have to be thrown away. You can always wear a
jump suit; disposable ones for painters are available,
starting at $5.
(2) Equipment contamination. Your cutting tools
and all your other equipment will gradually turn black.
Fortunately, old urushiol stains are not very allergenic. I
wore cotton gloves whenever I handled pruning shears, hand
clippers, etc. until I had had no reactions for two years, at
which time I no longer became itchy from the tools.
Identification of Poison-Oak:
See the "Identification"
brochure (.pdf file). In my experience, it takes several
months, with expert tutelage, to get good at it.
Preventive Measures include skin care and appropriate
clothing. See "Prevention: Skin Care"
and "Prevention: Clothing."
Treatment:
See "First Aid" and
"Medical Care." If you don't know how you'll react, it is
prudent to lay in the listed supplies. If you develop a
poison-oak rash during a trip, it may be time to move to safer
surroundings (e.g. from the campground to a motel in Morro
Bay) or end your trip.
