SampleMimosa Hostilis root bark is the outer bark of the Mimosa tenuiflora tree, native to north-eastern Brazil and Mexico. It is sold as a raw botanical material, valued by natural dyers for the deep purple it produces on wool, silk and leather, and by soap makers for its high tannin content.

Mimosa tenuiflora is a fast-growing tree found across north-eastern Brazil and parts of Mexico, where it is known locally as jurema or tepezcohuite. The bark of its root is harvested, dried and either milled to a powder or cut into a coarse shred.
What makes it interesting to craftspeople is tannin. The root bark carries an unusually high tannin load, which is what allows it to bond with protein fibres without an aggressive mordant, and what produces its characteristic purple-to-maroon range on wool and silk.
It is sold in two cuts. Powder disperses quickly and suits shorter baths and smaller pieces. Shredded bark releases pigment more slowly, which many dyers prefer for larger work where even uptake matters more than speed.
Colour depth is a function of fibre, mordant, bath temperature and time rather than of the bark alone. The same material will give a muted mauve on cotton and a deep aubergine on wool. Dyers usually keep notes per batch, because bark from different harvests varies.
One point we are direct about: this is a raw botanical material. It is not food, it is not a supplement, and it is not sold for human consumption. We sell it for dyeing, soap and cosmetic manufacture, craft and botanical research, and our checkout asks buyers to confirm that intended use.
Mimosa Hostilis root bark produces purple to maroon shades on protein fibres such as wool and silk. Colour depth depends on fibre type, mordant choice, bath temperature and time. Powder suits shorter baths; shredded bark suits longer ones and larger pieces.
Availability differs by product line because the law does. Botanical materials ship to all 50 states. Amanita products ship to 49. Vapor products are governed by the federal PACT Act and reach a considerably smaller set of states.
