Melanocyte-stimulating hormone is a collective name for a group of peptide hormones produced by the skin, pituitary gland and hypothalamus in response to ultraviolet (UV) radiation. It plays a key role in producing coloured pigmentation found in the skin, hair and eyes.n Addisonâs disease, the adrenal glands do not produce enough hormones (including cortisol). This leads to a positive feedback loop where the hypothalamus stimulates the pituitary gland to release more adrenocorticotropic hormone to try and stimulate the adrenal glands to produce more cortisol.
Mescaline is a natural hallucinogenic substance that comes from a small spineless cactus called the Peyote, or Lophophora williamsi; the San Pedro Cactus, or Echinopsis pachanoi; and the Peruvian Torch cactus, or the Echinopsis peruviana.
The cactus contains mescaline and other psychoactive alkaloids, and as such is commonly used as a psychotic drug. The drug is made from harvested 'buttons' that grow on the tops of the roots. The mescaline content of dried peyote is high (as much as six percent) but is only one percent in undried peyote.Interestingly enough, the purpose of the mescaline found in the peyote cactus is to repel potential predators.he drug is made from harvested 'buttons' that grow on the tops of the roots.
