Learning To Recognize Poison Ivy

We all know just how annoying poison ivy can be thanks to the rashes that they cause on our skin when it is exposed to the urushiol liquid. The urusiol only comes out when the plant is punctured. The best way to protect ourselves from it is to learn how to recognize the plant before we touch it.

The most common thing to remember is the saying that “leaves of three let them be”. This is true - but it is also important to remember that some plants in the poison ivy plant will look slightly different. Some plants like the Virginia creeper are harmless and will not leave a rash. So you must be able to determine the good from the bad.

A great way to help you is the “black spot” sign. The urushiol oxidizes rapidly when it is excreted from the plant and is touched by the air around it. The oxidation causes a darkening so that the initial clear fluid will turn a creamy color until it changes to dark black.

You do have the ability to examine the plant carefully this way only if it has already been damaged and the oxidation process has already been done. You may also look at it if you wear protective gloves to protect your skin.

*Note: Those of you with children should teach them the “leaves us three” rule. It is easier for them to remember.
