How it begins
The reaction from the plant is actually from the skin coming into contact with the plant’s oil. The urushiol oil is found in the flowers, stem, leaves and roots. It doesn’t take much to cause a reaction, but more importantly, they can remain active after the plant dies.
A rash generally appears 12 to 72 hours after contact with the plant or any object that has been exposed to the oil. This is due to the oil being absorbed and metabolized. Although the rash is not necessarily contagious, if the oil is transferred between skin to skin contact, the other person may suffer a rash as well.
Once you’ve identified the ivy, it is important to alert others of your find in order to better stop the accidental spread of the oil. If you’re thinking about clearing out poison ivy there are a few things you should be sure to do. Lessen the chance of contact by wearing long sleeves, pants, and gloves. More importantly, wash off all garden equipment used and remove clothing.
