The San Pedro cactus can be ingested in different ways. From just eating the cacti raw to chemically extracting the mescaline. We'll describe two easy ways one can prepare the San Pedro cactus for consumption. This can be done easily at home: Eating San Pedro raw and brewing a tea of San Pedro cactus. A bit further you will find a simplified guide for mescaline extraction and a link to an extensive guide.
Eat the cactus raw
That is easy! Remove all thorns, spines and prickles and start eating the San Pedro cacti like you would a cucumber, chewing every part of flesh and skin. The center of the cactus is the wooden like stem and can't be eaten. This method of ingesting could take a while if you have a big chunk of San Pedro cactus.
Brew a tea of the San Pedro
Cut the San Pedro in slices. The center of the cutting is woodlike and can't be cut, so basically you'll be cutting stars with a round opening where the stem was. Put the slices in a food-processor to grind them to a pulp. Use the pulp to make a tea. Add boiling water and let it simmer for a while, then sieve or drink it straight up with the pulp. Add lemon for flavor and vitamin C. The latter helps to make you take up the mescaline better.
Other preparation methods of San Pedro are drying, freezing, add ground San Pedro cactus to
or extracting the Mescaline.
Extracting Mescaline from San Pedro
There are numerous Mescaline extraction techniques. Well explain one of the simpler ones step by step:
Simmering the sliced San Pedro in water for 5 to 7 hours.
- You will need to wash and cut up the San Pedro Cactus.
- Remove all thorns, spines and prickles with a sharp knife.
- Slice of the outer peel until you see a green pulp, this is were most of the mescaline is stored.
- Remove all the green pulp from under the peel for use.
- Put the pulp in a cooking pot with one liter of fresh water and let simmer for 2-3 hours.
- Sieve the residue to seperate the liquid (← this is your first extract) from the pulp.
- Simmer this pulp for a second time with just another liter of fresh water during 2 hours.
- Sieve this again and this time throw out the pulp.
- Add the second to the first extract into the cooking pot.
- Boil this down for a couple of hours until you have 250ml to 500ml (1-2 cups) left and your extract is ready.
A far more complex technique is an acid-base extraction, 1 yielding a material with a significantly higher concentration of Mescaline. Would you like to go full ‘Breaking Bad’ on the San Pedro Cactus?

The San Pedro dosage is hard to get exactly right since San Pedro cacti that grow under different conditions will produce varying amounts of active substance. One underarms length, and about the same circumference, of San Pedro cactus cutting should be enough to extract a good dose of mescaline.
