Why Mimosa?

The Mimosa tenuiflora tree is a symbol of ancient regenerative healing. In the 10th century, the Mayans were already utilizing its bark for its incredible capability to heal wounds. Today we have discovered that its roots also contains one of the highest levels of DMT from any botanical known to man. At MIMOSA, we aim to bring the healing power of entheogens such as the Mimosa tenuiflora tree back into service for greater good of humanity.


Origin Story

Informed by ethical capitalism and grounded in morals and practices of the psychedelic community, Mimosa Therapeutics was formed as a Public Benefit Corporation.
