Frequently Asked Questions
What is the quality standard of Prime Hostilis MHRB?
At Prime Hostilis, quality is our core value. We provide 100% pure Mimosa hostilis inner root bark (MHRB). We manually remove all “white wood” (sapwood) and outer bark, which contain no value. Our 2026 Reserve is laboratory-verified for purity, ensuring you receive the most potent botanical specimen available.
How is your MHRB Powder processed?
We use a specialized cold-milling process. Standard grinding creates heat that can damage delicate botanical fibers. By keeping the bark cold during milling, we preserve the full phytochemical profile, resulting in a micro-fine powder that is superior for research and artisan applications.
What is the difference between Mexican and Brazilian Mimosa?
Mexican Mimosa (Tepezcohuite): Sourced from the highlands of Oaxaca, it is world-renowned for its deep purple hues and traditional use in skincare and soaps.
Brazilian Mimosa (Jurema Preta): Sourced from the arid Pernambuco region, it is often preferred by researchers for its specific mineral density and consistency.
Both varieties are strictly 100% inner root bark.
How should I store my MHRB?
To preserve the integrity of your bark or powder:
Keep it in the original vacuum-sealed packaging until use.
Store in a cool, dark, and dry location.
Avoid exposure to direct UV light or high humidity.
Properly stored, our MHRB maintains its full potency for years.
Is your shipping discreet?
Yes. Privacy is a top priority for our clients.
All orders are shipped in plain, unmarked packaging.
We use vacuum-sealing to ensure the package is flat and scent-free.
There are no mentions of “Mimosa” or “MHRB” on the outside of the box.
How do artisans use this product?
Our MHRB is a versatile botanical specimen used globally for:
Natural Pigments: Creating sustainable dyes for textiles, leather, and wood.
Artisanal Soaps: Utilizing the traditional properties of Tepezcohuite.

MHRB User Guide: Storage, Handling & Application
How to Store Mimosa Hostilis Inner Root Bark
To ensure your 2026 MHRB Reserve maintains its maximum phytochemical potency, proper storage is essential.
Avoid UV Exposure: Keep your Mexican Mimosa powder in a dark place. Light can degrade the natural tannins.
Temperature Control: Store in a cool, dry environment.
Airtight Seal: Once our vacuum-sealed packaging is opened, transfer the bark to a glass jar. This prevents the finely milled powder from absorbing moisture from the air.
Working with MHRB Powder vs. Shredded Bark
Our cold-milled MHRB powder is designed for high-efficiency projects. Because the surface area is much larger than shredded Mimosa hostilis, it requires less time for botanical extractions or natural dyeing.
Pro Tip: When using the powder for Tepezcohuite soap making, mix it with a small amount of carrier oil first to prevent clumping.
Natural Dye & Pigment Instructions
Mexican and Brazilian MHRB are world-renowned for producing deep purples and earthy crimson tones.
Preparation: For the most vibrant hues, use a 1:1 ratio of inner root bark to the weight of your fabric.
pH Sensitivity: The color profile of Jurema Preta can shift based on acidity. Adding a pinch of citric acid can brighten the reds, while a more alkaline environment shifts the dye toward deep purples.
Heat Warning: Never boil the bark. Simmering at low temperatures preserves the botanical alkaloids and prevents the dye from turning brown.
Safe Handling & Laboratory Best Practices
When working with laboratory-grade MHRB, we recommend the following:
Use a simple dust mask when handling ultra-fine MHRB powder to avoid inhalation.
Work in a well-ventilated area.
Ensure all equipment is cleaned with distilled water to maintain the purity of the botanical specimen.
