Moonflower has a high sulphur content. 3000 years ago, Central American Indians used this plant to create rubber from rubber tree sap. The sulphur cross linked the rubber molecules, producing the elastic effect. And now Charles Goodyear gets the credit for discovering this! He also played a key role in my family history. Mom and Dad met while working at Goodyear. Six degrees of removal, my foot! We are all so connected!
