Acacia rigidula, commonly known as Blackbrush Acacia or Chaparro Prieto, is a species of shrub or small tree in the legume family, Fabaceae. Its native range stretches from Texas in the United States south to central Mexico.[2] This perennial is closely related to A. berlandieri and is not listed as being threatened.[3] It reaches a height of 5–15 feet (1.5–4.6 m).[4] Blackbrush Acacia grows on limestone hillsides and canyons.[5]

Phytochemistry
A 1998 paper in the journal Phytochemistry indicates that the leaves and stems of A. rigidula contain 40 alkaloids and amines,[6] including:
- 3,4,5-Trihydroxy-phenethylamine (demethylated mescaline)[7]
- Methamphetamine
- Anhalamine[7]
- Beta-methyl-phenethylamine[7]
- Catechin[7]
- Dimethyltryptamine – 323.8 ppm spring, 568.4 ppm fall[6]
- Fisetin[7]
- Hordenine[7]
- Mescaline[7]
- N-Methyltryptamine – 4.6 ppm spring, 54.9 ppm fall[6]
- Nicotine[7]
- Nornicotine[7]
- Phenethylamine[7] – 2314.6 ppm spring, 5264.8 ppm fall[6]
- Quercetin[7]
- Tyramine[7]
- Tryptamine – 0.8 ppm spring, 21.2 ppm fall[6]
These findings have never been confirmed or discussed and are considered by some to be unlikely and a product of contamination or a hoax. Some of the apparently found phenylethylamines were previously only known as man-made and their discovery would have been quite revolutionary. Also the authors of the 1998 study did not answer written requests.[8]
Uses
Blackbrush Acacia is used in weight loss dietary supplements because of its adrenergic amine content. These substances stimulate beta-receptors to increase lipolysis and metabolic rate and decrease appetite.[9]
