Mimosa Hostilis Root Bark: Common Questions
What is Mimosa hostilis root bark?
It is the inner root bark of Mimosa tenuiflora, a small tree native to Mexico, Central America and north-eastern Brazil. It is also called tepezcohuite, jurema preta or MHRB, and it is valued for its high tannin content and deep purple-brown colour.
What is Mimosa hostilis root bark used for?
Craftspeople use it as a natural dye for fabric, yarn and leather, as a natural colourant in handmade soap, and as an ingredient in cosmetic formulations. We sell it as a raw material for these uses, not for human consumption.
Which form should I choose: whole, shredded or powder?
Choose shredded bark for dyeing fabric, because it strains cleanly. Choose powder for soap and cosmetics, because it blends evenly. Choose whole bark if you want the longest shelf life or prefer to process it yourself.
What colours does it produce?
Shades range from soft pink through dusty purple to deep red-brown. The result depends on the fibre, the amount of bark and any mordant: alum brightens the colour and iron darkens it.
What sizes do you sell?
Every form is available from 500 g up to 100 kg, so you can order a small test quantity or a bulk supply for a studio or resale.
How much bark do I need?
It depends on the weight of material you are dyeing and how deep you want the colour. Our dye calculator works it out in grams, ounces or pounds.
