Contact Allergy

Dr. Powlin Manuel is retired as of 1/1/22.

Contact dermatitis is caused by an allergic reaction to a chemical present in leaves, flowers, plants, or chemicals in a product. Contact allergic reactions are different in their mechanism which elicit a reaction because the reaction appears about 48 to 72 hours after exposure. Migration of immune cells to the area of contact and release of products of inflammation lead to redness, itching, swelling, and at time pustules appear around the area of contact. The allergen can vary depending on the plants and flowers present at the time of contact. The most common cause of contact allergy reaction is due to poison ivy.
