Mimosa hostilis is a drought-tolerant shrub native to Brazil and Southern Mexico. Its roots produce and store a substance known as DMT, which is highly toxic and produces hallucinations when consumed. The bark's dark color is also used to stain leather during tanning.
Sit the bark out in a well-ventilated room for 48 hours to make sure it is completely dry.
Place the bark in glass mason jars and cover the jars tightly with jar lids.
Store in a cool, dark place such as a kitchen pantry.
