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

The San Pedro cactus (Echinopsis pachanoi) originates in the mountains of Peru and Equador 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'.

    10/10 would cactus again
    We ordered 2 x medium (25-30cm) pieces of cactus with a total weight of 930g. This was consumed between 3 people and prepared using only the skin applying the freeze method (freeze, thaw, and blend) the drink. No boiling. This give us an all day love affair in cactus land. The duration of the trip lasted 16 hours and we started at 1pm in the afternoon and we went to early hours of morning. After reading internet dosages we were worried that 2 pieces of medium cactus would not be enough for 3 people but we were very much surprised. We also fasted which I believe heightened the trip. Would recommend being outside for at least part of the day however try to find somewhere safe and enclosed without public interaction.


    4 units
    I got 4 medium... 2 arrived with tips yellow but i think they will bounce back when they have roots. Only got one with a few light brow scarification lets see if it spreads or gets controled.


    Cactus fantastique
    Cactus de super qualité, arrivé en pleine forme, et s’adapte très bien à son nouveau environnement. Pas encore consommer, mais semble très prometteur.


    When the cactus arrived it was in perfect conditions, packaged well and looked healthy. I tried making a tea but it didn't go exactly as planned. I did some reaserch from various sources but they all made it in different ways, so i went with the one with the most positive feedback related to the views. I started by cutting the cactus to leave the center out, as i've read that it doesn't contain much mescaline and it mostly contributes to nausea. Then i took the skin off while paying attention not to damage the dark layer beneath it. I added water and the triangular pieces that i cut to a food processor and blended real good. After that i placed everything in a pot at low heat for approximately 4 hours while stirring continuously. I filtered the result and drank the tea. I had read that 30cm are enough for a mild to medium experience but i only got threshold effects that lasted quite a bit though. I thought it was because i threw up like 20' and 30' after consuming the tea but mescaline in the stomach is supposed to be absorbed pretty quickly (within 15') but idk. I m not sure if i did a mistake during the extraction process, if i shouldn't have cut out the center, if i threw up all the mescaline or if it was the cactus itself, but i couldn't find much insight on why it went like that, maybe you can help out?


    Came quickly and packaged safely. Planted and it's looking healthy and happy.


    Strong, well packaged San Pedro of 25-30cms
    Cactus was close to 30cms and came in great shape with blueish tints to it, meaning it is dormant and naturally preserving itself. Rooted indoors during the winter, it took up to 3 weeks after potting in a specialised soil mix I made, no water till a couple months after. I received a top cutting. Looking forward to see this one stretch out! Will come back and order the Peru/Bol Torches at some point.


    super healthy
    Best cactus ever! It´s growing really good and easy to take care of. I have never had a healthier plant


    ++++++++++++++++++Excellent Quality!++++++++++++++++++++++ VERY NICE! Everyone should try it!


    Good Quality
    Good quality and product arrived fast. I can recommend it!


    Non consiglio
    Purtroppo non ho avuto effetti, se non un po'di energia in più per tre ore. Ho inengerito la parte più esterna e bevuto il cuore come un thè, ma niente. Magari sono solo stato sfortunato. Al meno è un bell cactus di 30 cm per gli appassionati che vogliono crescerlo.
