Mimosa Hostilis Root Bark Powder (MHRB Powder)

Mimosa hostilis root bark powder (MHRB powder) is the finest-processed form of Jurema Preta, milled to a uniform consistency that maximizes surface area for rapid extractions and precise measurements. The inner root bark is harvested from mature Mimosa tenuiflora trees in northeastern Brazil, dried, and ground to a fine powder without fillers or additives.

This format is the go-to choice for researchers, natural dye professionals, and botanical enthusiasts who require fast-acting, measurable preparations. The powder dissolves readily in water-based solutions and produces a concentrated tannin extract ideal for high-intensity fabric dyeing applications.

The fine grind accelerates extraction times significantly compared to shredded or whole bark: a dye bath that takes 2–3 hours with shredded bark can be achieved in 30–45 minutes with powder. Available in sizes from 100g sample quantities to 1kg bulk bags.

Each batch is tested for purity and packed in moisture-barrier, resealable pouches. All material is 100% inner root bark — zero outer bark, zero fillers. Please check your local regulations before ordering.
