Blackbrush Acacia or Chaparro Prieto (Acacia rigidula) 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.[1] This perennial is closely related to A. berlandier and is not listed as being threatened.[2] It reaches a height of 5–15 feet (1.5–4.6 m).[3] Blackbrush Acacia grows on limestone hillsides and canyons.[4] It is also used as a fat burner.

Chemical compounds found in Acacia rigidula

  • 3,4,5-Trihydroxy-phenethylamine (demethylated mescaline)[5]
  • Methamphetamine
  • Anhalamine[5]
  • Beta-methyl-phenethylamine[5]
  • Catechin[5]
  • Dimethyltryptamine 323.8 ppm spring, 568.4 ppm fall[6]
  • Fisetin[5]
  • Hordenine[5]
  • Mescaline[5]
  • N-Methyltryptamine 4.6 ppm spring, 54.9 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.[7]
