Nuss says some common houseplants can cause skin irritation, including poinsettias, penciltrees, daffodils, hyacinths and ornamental buttercups. Most nettles can cause a toxic reaction when touched, but the reaction does not have lasting effects and requires no medical treatment. The most common plant-related injuries are caused by thorns. But implanted thorns, needles or spines can cause infections or other medical problems. Nuss says thorns embedded near joints can cause chronic arthritis.
Thorns embedded near bones can mimic a bone tumor.
Thorny plants that can cause painful injuries include roses, black locust and honeylocust trees and blackberry bushes. Be sure to wash all clothing and tools after working with problem plants. The residues can be hazardous for a long time. To read previous months' news releases, click on this link.
