Myristicin Safrole. The position of the missing OCH3 is arrowed. The transformation of safrole to Ecstasy can be shown as: Safrole 3,4-methylenedioxy-N-methylamphetamine or MDMA (Ecstasy) Safrole comes from the sassafras tree. Traces can also be found in cocoa, black pepper, mace, nutmeg, and wild ginger.

From Mauritius they spread all along the East African coast and especially to Zanzibar, where cloves quickly became the major export.

Death generally results from an acute infection such as pneumonia or some other respiratory ailment or, even in young people, from heart failure.
