July 8, 2026

Mimosa Hostilis rotbark, torkat naturmaterial

Mimosa Hostilis, botanically known as Mimosa tenuiflora, is a thorny, drought-tolerant tree that grows wild across northern and northeastern Latin America. Its root bark has a long tradition of use in the region – as a natural dye in textile craft, as part of folk skincare in Mexico, and as a culturally significant plant in northeastern Brazil. At Växtbutiken we sell the gently dried root bark, whole or ground, as a botanical raw material for anyone interested in the plant's history and craft applications.

Botany and origin

Mimosa tenuiflora belongs to the legume family (Fabaceae) and is native to the Caatinga biome of northeastern Brazil – a dry, thorny scrubland covering parts of the states of Bahia, Pernambuco, Ceará, Paraíba, and Rio Grande do Norte. The tree also occurs naturally northward through Mexico (Oaxaca, Chiapas) as well as in El Salvador, Honduras, Panama, Colombia, and Venezuela. It typically grows 4–8 meters tall, has feathery, mimosa-like leaves and fragrant white flower spikes, and is known as a pioneer species that recovers quickly after drought and wildfire. The bark is dark brown to gray on the outside but reddish-brown on the inside – which gave rise to several of its folk names.

Tepezcohuite – the Mexican skincare tradition

In Mexico the bark is called tepezcohuite, a name with roots in Nahuatl. There it has been used for generations in traditional folk medicine, mainly applied locally to the skin. Tepezcohuite gained international attention following two severe disasters in Mexico in the 1980s – the San Juan Ixhuatepec gas explosions in 1984 and the major Mexico City earthquake in 1985 – when, according to several contemporary reports, powdered bark was used by medical staff and the Red Cross to treat burn victims when conventional medical supplies ran short. These events strongly contributed to the bark's reputation as a valuable traditional resource for skin and wound care in Mexican folk medicine.

Jurema Sagrada – a sacred plant in northeastern Brazil

In its native Brazil, where the tree is called jurema preta, the root bark holds deep cultural and spiritual significance. It is central to Jurema Sagrada, a religious and ritual tradition rooted in Indigenous peoples such as the Potiguara and Tabajara of northeastern Brazil, which over time has woven together with Afro-Brazilian and folk Catholic elements in what is known as Catimbó. The tradition lives on today among several groups, including the Kariri, Pankararu, Truká, and Atikum, and the root of the jurema tree has historically been used to prepare a ceremonial drink that plays a central role in these contexts. It's part of the region's living cultural heritage – a reminder of how deeply a single plant can be interwoven with different peoples' spiritual lives, far beyond its practical uses.

Natural textile dyeing

The root bark contains a high tannin content – up to around 16 percent according to pharmacognostic studies – which has historically made it popular both as a leather-tanning agent and as a natural textile dye. Depending on the fiber, concentration, and any mordants used, dyeing can produce anything from warm reddish-brown and rust tones to deeper wine-red and purple shades. This makes the root bark a valued raw material for natural dyeing of yarn, fabric, and other natural fibers – especially for those who want to avoid synthetic dyes and work with craft traditions going back several hundred years.

Modern skincare and cosmetics

The Mexican skincare tradition around tepezcohuite has in recent years found its way into the commercial cosmetics industry, where extracts of the bark – often marketed under names like "the Mexican skin tree" – appear in products that highlight the bark's natural tannins and its reputation as a gentle skincare ingredient. As with other botanical raw materials with a long tradition, interest in Mimosa tenuiflora has grown as more people seek out natural alternatives in skincare and craft.

Our root bark – whole or ground

At Växtbutiken we sell Mimosa Hostilis root bark as a botanical raw material, gently dried and available both as whole pieces and as ground powder – depending on whether you want to work with dyeing, craft, or other creative projects. As with all dried plant material, we recommend storing it dark, dry, and airtight for the best shelf life, and always testing in smaller batches first if you're experimenting with dyeing or new recipes.
