Mimosa hostilis is a tree from Brazil, where it is better known as Jurema Preta. Its rootbark contains a visionary tryptamine. Mimosa hostilis is often used together with Peganum harmala to produce an effective and easy to prepare Ayahuasca analogue.
In combination with an MAO-inhibitor the dosage is 5 to 20 grams of Mimosa hostilis. Taken by itself (as a cold water infusion) a higher dosage is required: between 25 and 45 grams.
