Okay, so who hasn’t been told “leaves of three let them
be?” I grew up with that saying and had
to remember it while walking around in my own back yard. It was knowledge passed through oral
communication, and it’s knowledge I will never forget. Along with the saying comes the
precautions. Now that you know the
saying, heed it. You are less likely to
get poison oak, if you don’t touch it.
If you seen around, even if your sure you didn’t touch it, take a cold
shower afterwards and its probably best to take a few cold showers
afterward. We take cold showers because
hot showers open up your pores and allow the irritating oil into your skin,
which can result in icky bumps or disgusting oozing messes.
All cultures have poisonous plants that they need to avoid,
but I will concentrate on the Native American tribes from what is now northern California . These people knew how to use poison oak. The used the plant to make die, the stems to make baskets and the roots for food. They obviously understood something that we don't, or built up immunity. Those who made their home in this area before
the arrival of Europeans, and even after the arrival of Europeans, were able to
survive by living off acorns. However,
the acorns could not be eaten raw, and had to be put through a process to
become edible. The acorns of the area
contain a poison called tannic acid that makes acorns bitter and, if eaten in
large quantities, can cause death. The
knowledge of how to “leach” acorns, remove the tannic acid, is domestic
knowledge. This knowledge was maintained
through oral explanation and constant practice.
