Finely powdered Mimosa Hostilis inner root bark. This product is imported from Brazil and is also known by other names: Jurema Preta, Tepezcohuite and Mimosa Tenuiflora (MHRB). This MHRB has a deep dark color and is very dense given the manner in which is it powdered.
We powder our own root bark to ensure it is 100% pure and organic root bark and not trunk bark. We only offer inner root bark from old Mimosa trees from Brazil. The root bark from old trees is richer in tannins than the root bark from younger trees; therefore, this bark is perfect for use as a natural dye and leather production. Not only does the root bark from old Jurema Preta trees has a higher tannin content, it is a little darker and thicker than bark from younger Jurema Preta trees.
This powder has a similar texture to regular flour and is always kept in a dry place under a cool temperature. Our powdering process is done with a hammer mill using a 1mm mesh to ensure all parts of the root bark are grinded into a fine powder.
Recommendations for storage: Keep in a cool and dry place, and avoid leaving any air inside the bag if storing for later use.
