Urushiol is a generic name that indicates a mixture of
several close alkylcatechols contained in the sap of the
Anacardiaceae family such as Toxicodendron radicans
Kuntze (poison ivy) or Anacardium occidentale L.
(cashew nut tree). The R-side chain generally includes
13, 15, or 17 carbons. A urushiol with a C15 side chain
is named pentadecylcatechol (a term sometimes
employed in medical literature for poison ivy urushiol),
and a urushiol with a C17 side chain is a heptadecylcatechol
(mostly encountered in poison oak urushiol).
