Study Findings

• Cross Sensitivity Study: Cross-sensitivity studies were done on alkylresorcinols from extracts of Philodendron scadens and Philodendron lacerum and alkylcatechols from an extract of Toxicodendron radicans (poison ivy). Patients sensitive to Philodendron species (or other resorcinol-containing plants) may not be necessarily be cross-sensitiv e to Toxicocdendron species and vice versa.

Wild-crafted or cultivated.
