Fractal Cloud a dit:Bellissima esperienza e bellissimo racconto, grazie della condivisione! Soprattutto perché di esperienze con la mescalina ne ho trovate veramente poche, almeno nella sezione in italiano, mentre quelle con funghi, LSD, DMT etc abbondano.
Ma eri alla tua prima esperienza psichedelica?
roxyblue a dit:Grazie Davvero Mille, davvero. mi sentivo perso..perchè i vostri threed erano di tanto tempo fà e dubitavo di una pronta risposta (sorry, sorry, sorry).
Cmq come San pedro ci siamo? è lui?
Oddio, spiegami in che senso spostata e dove? (sono ebete per i forum).
Scusate se insisto Ragazzi, ma avrei un po di fretta. Qualcuno sa dirmi se è un pachanoi san pedro quello in foto che ho postato perchè vedendo le immagini sui threeds non so identificarlo?
Grazie mille e scusate l' insistenza.
Horror Vacui a dit:A me come aspetto pare essere lui ma non garantisco nulla. Non sono un esperto.
Ciò che mi sembra anomalo è il colore. Magari (e sto facendo delle ipotesi) è dovuto a condizioni e/o tipologia del terreno, alle condizioni di salute oppure ad altri aspetti simili. Devo dire che a giudicare dalla foto, le circostanze in cui è tenuto non sembrano eccellenti.
Ti spiego, le discussioni che vedi (come quella che tu hai iniziato facendo questa domanda) sono chiamate thread o topic.
Nel tuo caso è avvenuto che essendoci già una discussione sui cactus, il tuo thread è stato inglobato al suo interno (cioè all'interno della discussione già esistente).
Non preoccuparti, intuisco che per te si tratta di una delle prime esperienze su un forum, quindi è normale un po' di confusione iniziale
Preso da: Trout's notes on San PedroIt must be kept in mind that substantial differences in the alkaloid content and in the relative ratios of alkaloids present have been noted by numerous researchers. (True in many families) These differences have been noted to sometimes appear seasonally, such as the higher presence of N-methylated (as compared to N- demethylated) alkaloids detected by Lundstrom during summer in greenhouse maintained peyote. In contrast; in the same population of plants, winter analysis found levels of N- demethylated compounds to be higher than N-methylated ones. [While he used cultivated plants, the mescaline content was comparable to most of what is collected from the wild.]
They can vary as well according to the age of plant (young plant versus adult plant) or even by age of part. In cacti, the actual variables are largely unstudied.
Alkaloid content has been noticed to vary substantially in amount and/or even actual composition between varieties considered closely related by morphology, and concentrations sometimes vary widely even from one individual or locality to the next. In other families even daily fluctuations have been noted; in Phalaris and Papaver, for example, alkaloid concentrations were often found to be higher in the morning but this area still needs more study. (Quantitative comparative isolations of Papaver were published in FAIRBAIRN & WASSEL 1964 & Phalaris was reported by APPLESEED)
Very few workers seem concerned with any of this, and work on this subject has rarely been performed or published.
Species suggested by published analysis to be variously weak or potent have on occasion proven to be the opposite! Often the only data included is whether the plant was cultivated or collected from the wild. In many early papers we literally have to rely on the word of the workers as to the identity of what they analyzed, as vouchers were never
prepared and there is no physical means for confirmation. In recent decades, more attention is being given to the importance of herbarium vouchers being prepared to accompany the analysis. Even then, not all workers note
enough variables for their observations to have meaning. Size and approximate age, part of plant used and stage of growth, i.e. actively growing versus fully developed (if sampling only branches of large specimens), and time of harvest (time of year and time of day) should all be considered to be critical data to include along with place of origin. Ideally for a voucher, local ecology and a description of habitat would also be quite valuable (Plants associated with it, conditions of occurrence, and a description of the
terrain) Even better would be
also including a local soil test, and analyzing different parts and ages of the material, repeating the tests with the same specimens at different times of year
If performing repeated samplings of the same individuals, stress can become a factor capable of influencing the results. I suggest initially using pooled smaller samples of adjacent individuals within a given population with additional small samples being from several individuals within the population that is
pooled to check uniformity. Most plants can recover rapidly and well from light prunings. A minimum of two years time is suggested for a series of samplings. Differences in regrowth versus original growth should also be evaluated.
The factors controlling alkaloid production would be a fascinating and productive area for future academic research. If chemotaxonomy is to ever be considered a truly useful inclusion in the repertoire of taxonomic tools, the parameters of alkaloid production must be better defined.
Determining and taking steps to maximize alkaloid content would also be of benefit for those who view these plants as sacraments. Selection for known high alkaloid strains or focusing on clones of specific exceptional individuals for intensive large scale breeding and propagation efforts would be a worthwhile avenue for everyone involved with sacramental use of these plants.

The San Pedro cactus is very easy to grow in most areas. Because it grows naturally in the Andes Mountains at high altitude and with high rainfall, it can withstand temperatures far below that of many other cacti. It requires fertile, free-draining soil. They average half a meter per year of new growth. They are susceptible to fungal diseases if over-watered, but are not nearly as sensitive as many other cacti, especially in warm weather. They can be sunburned and display a yellowing chlorotic reaction to overexposure to sunlight.
In winter, plants will etiolate, or become thin, due to lower levels of light. This may be problematic if the etiolated zone is not sufficiently strong to support future growth as the cactus may break in strong winds.
