San Pedro (Echinopsis pachanoi): Previously known as 'Trichocereus pachanoi'

The San Pedro cactus (Echinopsis pachanoi) originates in the mountains of Peru and Ecuador where this mescaline cactus grows at an altitude of 2000-3000 meter. Nowadays this cactus can be found in other parts of the Andes, such as the Argentinean and Bolivian mountains. The San Pedro is a rapidly growing cactus: under the right circumstances, this cactus can grow up to 30 to 40 cm a year.

The San Pedro cactus has a extensive history in shamanic culture. The most ancient signs of ritual use date back to 2000 years ago. Since the beginning of civilization in the Andes region, local shamans were using the San Pedro as part of their rituals, hailing the cactus as the “Materia Prima’. It was used not only as a religious sacrament, but also as a shamanic medicine.

Unlike the Peyote cactus and the psilocybin mushrooms, the use of the San Pedro cactus was not punished by the catholic inquisition. It is also very surprising that this holy Indian plant bears the name of a catholic saint. How this came to be is unknown till this day.


The San Pedro contains mescaline, a psychoactive alkaloid with potent psychedelic and hallucinative effects. Users of mescaline attest to strong visual effects, an altered conscious, feelings of euphoria and intense harmony with nature. The normal dosage of mescaline is 0.3-0.4 gram (pure mescaline, not 0.3-0.4 grams of cactus). The consumption of mescaline cacti can induce heavy vomiting. According to original users this purging should be experienced as a positive, it is the cleansing of the body.

For the fanatics: the chemical formula for mescaline is 3,4,5-trimethoxyphenethylamine.

How To Dose Mescaline Cacti Properly

Cultivating the San Pedro cactus

Our cuttings of the San Pedro are exclusively derived from healthy and attractive cacti. These cuttings facilitate the home cultivation of your own San Pedro cactus. The cutting only needs to be placed in the ground after which the cutting will soon shoot roots and continue to grow, like it had never been out of the ground in the first place. Use special cactus soil and not the standard soil for indoor plants. This soil often contains an incorrect ratio of nutrients needed for cacti.

Water the cactus once a week in autumn and spring and only once every 2-3 weeks in winter. In summer you may water the cactus 3-5 times a week. The best method is to water the cactus from the bottom, so it is better to put the cactus in a pot with a punctured base. Place the pot in a shallow dish with water en the cactus will absorb what it needs. This method is preferred over watering the cactus with a spout from above.

Place the San Pedro cutting in the shade for the first month, allowing the cactus to adjust to its new surroundings and create a new root system. You will not need to water the cutting for the first 2-3 weeks.

Name change: From Trichocereus to Echinopsis

The Latin name for the San Pedro cactus has always been 'Trichocereus pachanoi', but recently a new classification for the cactus species was put in place. Now the San Pedro is subordinate to the much larger cacti family Echinopsis. The current and correct name for the San Pedro is therefore ‘Echinopsis pachanoi'. The name change has not yet caught on with the masses and the cactus is still commonly referred to as 'Trichocereus pachanoi'. It will probably take quite some time before people speak of the 'Echinopsis pachanoi'.

    Arrived in time, great service and great product! I still haven’t try it yet, but sure it will be good.


    Waar voor je geld!
    Mooie cuttings, ik laat ze lekker wortelen en alles wat er uit groeit is welkom. Mooi voor in de vensterbank, mooi om mee weg te dromen.


    Beste Qualität
    Ich habe mir einen mittelgroßen Cut bestellt. Der Kaktus kam absolut unbeschädigt und gesund an. Die Schnittstelle war schon gut angetrocknet, sodass ich ihn direkt in den Topf gestellt habe. Erste Wurzeln sind nach 5 Wochen ausgetrieben. Die Wirksamkeit habe ich noch nicht getestet, aber da bin ich zuversichtlich.


    Deshidratado como mi bolsa escrotal.
    Muy bien y muy bonito. Llegó en buen estado aunque más deshidratado que mis cojones tras ver a mi ex novia en las fiestas de mi pueblo. Tocará ver como crece.


    Received a cactus cutting 52.5 cm long with 6 cm "diameter", as measured from the protruded ends. It was excellent, better than expected. What I received was very strong, probably too much for a single person without experience or a sitter. Will order again in the future :)


    5 cacti medium size
    I ordered 5 cacti of medium size :D everything arrived well and i will try them out some time, when i am less busy + report :D




    Fantastico San Pedro
    La talea è arrivata ben imballata ed in ottima salute, dopo quasi un mese ha radicato e si è stabilizzata nel terreno.


    A gentle but powerful healing psychedelic experience
    I ordered 1 cacti of medium size 25-30cm and removed the vax and removed only the green layer without the white as in the description in the link i will post below. Than I mixed it and added 3 liters of water and cooked it on low temperature for about 2,5-3 hours until it was a very concentrated green liquid 1-1,5 dl. I fasted for 6 hours. I drank the tea inside my apartment and the taste was bitter but I liked it the I sat and meditated and listened to peyote and san pedro Icaros. It came up veeery slowly. After almost an hour I felt the first bodily signs and something in the stomach and my heartbet was going up and after 3 hours an alertness was increased and I started doing Yoga with a focus and attention that I dont have otherwise. I had almost no nausea and I had no stomach pain due to this method of preparing without rthe white pulp. After 4,5 hours after have som emotional ups and downs I felt that I had eaten too little. After I had eating I was 5 hours in the trip and now it was peaking and I felt increasing stimulant effects with increased energy and stamina and simultanously increased psychedelic effects. I decided to go out in the nature and went out and the effects just increased and it started raining and I just enjoyed the nature and went in the forest and up in the mountains near the lake. The visual effects was not so strong but noticable with saturated colours and mindfulness of the fractals in nature. Ecstatic feelings and euphoria that I have not experieced on other psychedelics. It felt like a natural MDMA with psychedelic effects. I hade lot of energy but not in the forced way like stimulants and I was dancing and did some spontanous yoga movements and it felt so healing. After 8-9 hours when it was dark I decided to go home but was not tired yet even if the effects starting to subside. I was in an ecstatic mode and fell asleep after 11-12 hours. This was what i would rate somewhere between a mild and average trip. It was a very external trip compared to psilocybin and Dmt and not so intense but very healing and I recomend to do it in the nature. One of my best trips ever and the after effects the days after and the healing process was surprising. Next time I will take a larger dose.
