MHRB
Mimosa Hostilis Root Bark
Mimosa Hostilis Root Bark (MHRB) is the root bark of Mimosa Hostilis and is widely used to extract DMT from.
Mimosa hostilis
Mimosa hostilis is the former scientific name for Mimosa tenuiflora, and the two names are synonymous [1][2]. The older name is still widely know due to its presence in the literature and as distributers of botanical products still use the older term. M. tenuiflora is an entheogen known as Jurema, Jurema Preta, Black Jurema, and Vinho de Jurema. Dried Mexican Mimosa Hostilis root bark has been recently shown to have a DMT content of about 1%. The stem bark has about 0.03% DMT.
To date no β-carbolines such as harmala alkaloids have been detected in Mimosa tenuiflora decoctions, however the isolation of a new compound called "Yuremamine" from Mimosa tenuiflora as reported in 2005 represents a new class of phyto-indoles [3]. This may explain the reported oral activity of DMT in Jurema without the addition of an MAOI. Imported MHRB typically requires the addition of an MAOI in the preparation of ayahuasca.
