Toxic plant oils contain chemical markers (urushiol) which bond to cell membrane proteins, re-identifying our cells as targets for our own immune system. This can quickly become a significant health risk. This booklet identifies five toxic plants and explains our body’s mysterious response to their irritating properties. We recommend reading this booklet to prevent unpleasant experiences with Cape Cod vegetation.
