Welcome to the Zanfel Zone! As always, Zanfel Laboratories is here to provide you with important information on plant identification, prevention, and treatment.

Working Around Poison Ivy and Poison Oak

Tips for reducing exposures and misery:

  1. Plant Identification. In the US, there are two species of poison ivy and two species of poison oak. The shape of the plants’ leaves can vary widely from one place to the next. Be suspicious of any climbing vine that uses aerial roots to attach to trees. (For free copies of Zanfel’s education resources on plant ID, please click on the “Want To Learn More” link)
  2. Remember that all parts of the plant are toxic. The plants’ toxin, urushiol, is an oil that is found not only in the leaves, but also in the vines, aerial roots, stems, and roots. Running a chainsaw through a poison ivy stem or vine can spray your skin and clothing with urushiol, the plants’ rash inducing oil.
  3. It only takes about 60 minutes for urushiol oil to absorb into the skin. If exposure is suspected, wash the exposed skin ASAP with soap and cool water to remove as much unabsorbed urushiol as possible. If it has been more than 60 minutes, the urushiol is already in your skin and “regular” soap and water is no longer effective.

Zanfel can be used as a post-exposure preventative to remove the urushiol that has already bonded with the skin, thereby either preventing, or greatly reducing the severity of the reaction.

  1. Rash treatment: Zanfel is the ONLY product clinically shown to remove urushiol from the skin, ANYTIME after outbreak of the rash. For most mild to moderate reactions, the use of Zanfel completely stops the itching, and puts the body in a position to heal the rash. Zanfel allows the poison ivy/oak affected employee to quickly return to work in an itch free and healing state. For severe or systemic cases, Zanfel can be used in conjunction with a prescribed steroid medication.

Where Horticulture Meets High Adventure

We are proud to help announce the launch of a crowd funding campaign for a new poison ivy themed graphic novel.

Prepare For Poison Ivy’s Fall Colors

One of the early signs of fall is the turning of poison ivy leaves from green to yellow, and then to a bright red. Poison ivy is usually one of the very first plants to have its leaves change in the fall. You’ll look out into the woods and everything will be green, except for the bright yellow or red leaves on a climbing poison ivy vine.
