Lab-Tested Mimosa Hostilis Root Bark — No Fillers
The Mimosa hostilis tree has three parts below ground: the outer bark, the inner root bark and the woody core. Only the inner root bark carries the rich reddish-brown color buyers look for. Unfortunately, many sellers bulk up their bags with outer bark, stems, leaves or even sawdust.
In contrast, every bag of our Mimosa hostilis root bark is 100% inner root bark, inspected by hand. Furthermore, every batch is sent to an independent third-party laboratory before it's sold.
- Botanical authenticity — confirmed Mimosa tenuiflora, no substitute species
- Purity screening — heavy metals, molds, yeast, E. coli, salmonella and pesticides
- Consistency — natural color and quality you can rely on, batch after batch
Mimosa Hostilis Root Bark for Natural Dyeing
Mimosa hostilis root bark is naturally rich in tannins — roughly 16%. For this reason, it has long been used in leather tanning, and today it is prized by natural dyers.
Depending on your fiber, mordant and water, it can produce shades from warm browns and rusts to deep plums and mauves on wool, silk, cotton and linen. For example, our Brazilian MHRB powder releases color quickly, while Mexican shredded bark is easy to strain from a dye bath.
Ethically Harvested Mimosa Hostilis Root Bark
Our Mimosa hostilis root bark comes from trusted cultivated sources in northeastern Brazil and the Chiapas region of southern Mexico. In other words, it comes from where the tree grows naturally and regrows year-round.

Mimosa Hostilis Root Bark FAQ
Below are quick answers to the questions we hear most about Mimosa hostilis root bark. For more, see the full FAQ page.
What is Mimosa hostilis root bark (MHRB)?
MHRB is the inner root bark of Mimosa hostilis (Mimosa tenuiflora), a perennial tree native to Brazil and Mexico. It's prized for its rich natural color and high tannin content. Unlike many sellers' bags, ours is 100% inner root bark — no stems, leaves, outer bark or fillers.
How do I know I'm getting authentic Mimosa hostilis?
Every batch is tested by an independent laboratory to confirm it's genuine Mimosa tenuiflora with no substitute species. In addition, authentic inner root bark has a deep reddish-brown color and fibrous texture. Contact us to request a batch lab report.
What's the difference between inner root bark, outer bark and stems?
The inner root bark is the reddish, fibrous layer beneath the root's rough outer bark. Outer bark, stems and the woody core are cheaper and lack the inner bark's color, so some sellers mix them in to bulk up bags. In contrast, we sell inner root bark only.
Is your Mimosa hostilis ethically sourced?
Yes. Specifically, we source from trusted cultivated sources in northeastern Brazil and Chiapas, Mexico — the plant's native range — where Mimosa hostilis regrows throughout the year.
What does "lab-tested" mean?
It means we send every batch to an independent third-party lab that first confirms botanical authenticity and screens for heavy metals, molds, yeast, E. coli, salmonella and pesticides.
How long does shipping take?
United States 5–10 business days, Canada 7–12, United Kingdom 5–8, European Union 5–10, and Australia & New Zealand 10–15. In every case, orders include tracking, and orders over $300 ship free. For other countries, contact us.
Do you ship discreetly?
Yes. All orders ship in discreet, plain packaging and, in addition, carry accurate customs declarations.
