Vachellia rigidula, commonly known as Blackbrush Acacia or Chaparro Prieto, and also known as 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.[2] This perennial 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 phytochemical study of V. rigidula[6] by workers at the Texas A & M University Agricultural Research and Extension Center at Uvalde, TX, reported the presence of over forty alkaloids, including low amounts (up to ~ 15 ppm) of several amphetamines that had previously been found by the same research group in the related species Senegalia berlandieri,[7] but which otherwise are known only as products of laboratory synthesis. Compounds found in the highest concentrations (ranging from a few hundred to a few thousand ppm) were phenylethylamine, N-methylphenethylamine, tyramine and N-methyltyramine. Other notable compounds reported were N,N-dimethyltryptamine, mescaline, amphetamine, methamphetamine and nicotine, although these were found in low concentrations (e.g. mescaline at 3-28 ppm).
The presence of such an unprecedented chemical range of psychoactive compounds, including ones not previously found in nature, in a single plant species has led to the suggestion that some of these findings may have resulted from cross-contamination or were possibly artifacts of the analytical technique.[8]
Uses
V. rigidula is used in weight loss dietary supplements because of the presence of chemical compounds claimed to stimulate beta-receptors to increase lipolysis and metabolic rate and decrease appetite.[9]
V. rigidula is also known as a large honey producer and early blooming plant for its native region.[10]
Safety
In 2015, 52% of supplements labeled as containing Acacia rigidula were found to be adulterated with synthetic BMPEA, an amphetamine isomer.[11] Consumers following recommended maximum daily servings would consume a maximum of 94 mg of BMPEA per day.[11] In 2012, however, the FDA determined that BMPEA was not naturally present in Acacia rigidula leaves.[12]
