Jurema Preta (Mimosa hostilis) is a South American ethnobotanical root bark that's been used in Brazilian Jurema ceremonies for centuries. This category covers shredded root bark sold for botanical study, incense, and natural dye work — not consumption. One product lives here: Jurema Preta (Mimosa hostilis) 25 grams. If you're looking to buy authentic MHRB from a shop that's been handling ethnobotanicals since 1999, you're in the right spot.
Buy Jurema Preta — What This Category Actually Is
Jurema Preta is the Brazilian vernacular name for Mimosa hostilis (also called Mimosa tenuiflora), a thorny tree native to northeastern Brazil and parts of Mexico. The root bark — abbreviated MHRB in collector circles — has been central to Jurema cult practices among the Pankararu, Fulni-ô, and other Indigenous peoples for at least 400 years. Portuguese Jesuit records from the 1700s already mention it.
Outside ceremonial context, MHRB has two practical uses that keep it in global shops: it's a genuinely excellent natural dye (produces deep purples and browns that textile artists swear by), and it's a botanical specimen for people who study ethnopharmacology. The bark contains tannins at roughly 16% by dry weight according to Brazilian phytochemistry studies — which is why dyers love it and why it's been used in traditional tanning for generations.
Shredded Bark vs Powdered vs Whole — How to Choose
The format matters more than most first-time buyers realise. Shredded root bark is the middle ground: finer than whole bark chunks, coarser than powder. Here's the honest breakdown of what you'll find on the market when you shop for MHRB.
| Format | Best for | Shelf life | Handling |
|---|---|---|---|
| Shredded (what we stock) | Dye work, botanical study, collectors who want to see the material | Long — bark structure mostly intact | Easy to weigh, store, and visually verify |
| Powdered | Dye baths where fast extraction matters | Shorter — more surface area exposed | Messy, harder to verify authenticity |
| Whole bark strips | Collectors, long-term storage | Longest | Needs processing before use |
We'd pick shredded every time for a first order. You can actually see what you're getting — the pinkish-red inner bark colour is the quickest authenticity check, and powder hides that completely. Shredded also stores for years in a sealed jar without meaningful degradation, whereas powder oxidises faster.
What's In This Category
Right now there's one listing: Jurema Preta (Mimosa hostilis) shredded root bark in a 25g portion, intended as an ethnobotanical specimen. That's the whole category. If you need larger quantities or a different cut, get in touch — we've sourced MHRB from Brazilian suppliers since the early 2000s and can usually point you somewhere sensible.
How to Choose Your MHRB
Three things matter when you're deciding what to order: origin, freshness, and format. Brazilian-sourced bark from the Caatinga region is the historical standard and what most ethnobotanical literature references. Mexican Mimosa tenuiflora is botanically the same species but grown in different soil — some dyers prefer one over the other for colour depth. Freshness shows in the colour: proper MHRB has a reddish-purple inner layer. Grey, brown, or yellow bark means it's old or was harvested from stem rather than root.
If you're new to ethnobotanicals, start small. A 25g portion is plenty for dye experiments on a few metres of fabric, or for a botanical reference sample. You don't need a kilo to find out if this is something you want to work with long-term.
This page is written for adults. MHRB is sold as a botanical specimen and dye material — not for consumption.
Frequently Asked Questions
What is Jurema Preta used for?
Historically, it's central to Jurema religious ceremonies in northeastern Brazil. Today, most buyers use MHRB as a natural textile dye (it produces deep purples and browns thanks to ~16% tannin content) or as an ethnobotanical study specimen. It's also used in traditional leather tanning.
Is Mimosa hostilis the same as Mimosa tenuiflora?
Yes — they're two names for the same species. Mimosa tenuiflora is the currently accepted botanical name; Mimosa hostilis is the older synonym still widely used in trade and ethnobotanical literature. You'll see both on supplier labels.
How do I store shredded Jurema Preta root bark?
Keep it in a sealed glass jar away from light, heat, and humidity. Stored properly, shredded MHRB holds its colour and bark structure for years. Powdered versions degrade faster because of increased surface area exposure to air.
How can I tell if MHRB is authentic?
Look at the inner bark colour — genuine Brazilian MHRB has a distinctive pinkish-red to purple inner layer. Grey, yellow, or uniformly brown material usually means stem bark, old stock, or a different species entirely. Shredded format lets you verify this visually; powder doesn't.
