Mescaline Mescaline Mescaline (3,4,5-trimethoxyphenethylamine) is a naturally occurring psychedelic alkaloid of the phenethylamine class, known for its hallucinogenic effects comparable to those of LSD and psilocybin. It occurs naturally in the peyote cactus ("Lophophora williamsii"), the San Pedro cactus ("Echinopsis pachanoi"), the Peruvian torch ("Echinopsis peruviana"), and other members of the Cactaceae plant family. It is also found in small amounts in certain members of the Fabaceae (bean) family, including "Acacia berlandieri". However those claims concerning Acacia species have been challenged and have been unsupported in additional analysis. Peyote has been used for at least 5,700 years by Native Americans in
Plant–soil feedback of the other species ("G"(away) for plant species "x"). Then, the interaction coefficient is calculated as If "I" is negative, it means that both species grow worse in their own site compared to their competitor's soil, and therefore plant–soil feedback helps these species to coexist. Plant–soil feedback Plant–soil feedback is a process where plants alter the biotic and abiotic qualities of soil they grow in, which then alters the ability of plants to grow in that soil in the future. Negative plant–soil feedback occurs when plants are less able to grow in soil that was previously occupied by a member
