This guide explains the legal status of Mimosa hostilis in the United States, its common lawful applications, and what customers should know before purchasing.

Mimosa hostilis at a glance

Mimosa hostilis (Mimosa tenuiflora), also called jurema preta in Brazil and tepezcohuite in Mexico, is a thorny tree native to northeastern Brazil and Mexico. Its root bark is prized for natural tannins and pigments used in dyeing, leatherwork and cosmetics.

For a full overview of the plant, its names and how to identify it, see our Mimosa hostilis guide. This page focuses on what U.S. law says.

Different parts of the plant include:

• Root bark
• Trunk bark and wood
• Seeds
• Flowers
• Leaves

These botanical materials have different applications, from ornamental cultivation and botanical study to manufacturing and artistic projects.

Federal legal status of Mimosa hostilis

Mimosa hostilis and Mimosa tenuiflora are not specifically named in the federal schedules of controlled substances under the U.S. Controlled Substances Act.

This distinction is important because the plant itself is not expressly scheduled by its botanical name.

However, federal law regulates certain naturally occurring compounds and materials containing them. Consequently, the legal status of a particular product or preparation may depend on its composition, intended use, and other circumstances.

For customers interested in ordinary botanical applications, the important consideration is that Mimosa hostilis has established uses unrelated to controlled substances.

Are other parts of the plant legal?

The federal controlled-substance schedules do not separately name Mimosa hostilis seeds, flowers, leaves, wood, or root bark as prohibited botanical species.

These plant materials may be used in legitimate activities, subject to applicable federal, state, and local regulations.

Examples include ornamental gardening, botanical education, natural dyeing, textile projects, and research.

Common lawful uses

Here is a short summary of the lawful uses customers ask about most. For the full rundown, see our guide to Mimosa hostilis root bark uses.

Mimosa hostilis is also of interest in traditional craftwork, natural pigment projects, and artistic applications.

Cosmetics and skincare

Mimosa tenuiflora has a history of use in skincare traditions and is of interest as a botanical ingredient in cosmetic formulations.

Manufacturers using botanical ingredients must comply with applicable product safety, labeling, and FDA requirements. Products marketed to treat or prevent diseases may be regulated differently from ordinary cosmetics.

Although Mimosa hostilis is not specifically listed as a controlled plant under federal law, state laws can impose additional restrictions.

Some state statutes specifically address certain botanical species, preparations, or intended uses. These restrictions do not necessarily apply in the same way to every botanical activity.

Customers should review applicable state and local laws before purchasing, cultivating, processing, or using botanical materials.
