Echinopsis pachanoi (syn. Trichocereus pachanoi) -- known as San Pedro cactus -- is a fast-growing columnar cactus native to the Andes Mountains at 2,000-3,000 m (6,600-9,800 ft) in altitude. It is found in Argentina, Bolivia, Chile, Ecuador and Peru, and it is cultivated in other parts of the world. Uses for it include traditional medicine and traditional veterinary medicine, and it is widely grown as an ornamental cactus. It has been used for healing and religious divination in the Andes Mountains region for over 3,000 years. It is sometimes confused with its close relative Echinopsis peruviana (Peruvian torch cactus).

Description
Echinopsis pachanoi is native to Ecuador and Peru. Its stems are light to dark green, sometimes glaucous, with a diameter of 6-15 cm (2.4-5.9 in) and usually 6-8 ribs. The whitish areoles may produce up to seven yellow to brown spines, each up to 2 cm (0.8 in) long; the plant is sometimes spineless. The areoles are spaced evenly along the ribs, approximately 2 cm (0.8 in) apart. Echinopsis pachanoi is normally 3-6 m (10-20 ft) tall and has multiple branches, usually extending from the base. The tallest recorded specimen was 12.2 metres (40 ft) tall. White flowers are produced at the end of the stems; they open at night. The flowers are large, around 19-24 cm (7.5-9.4 in) long with a diameter of up to 20 cm (7.9 in). There are black hairs along the length of the tube leading to the flower. Oblong dark green fruits are produced after fertilization, about 3 cm (1.2 in) across and 5-6 cm (2.0-2.4 in) long.
Traditional uses
Echinopsis pachanoi has a long history of being used in Andean traditional medicine. Archeological studies have found evidence of use going back two thousand years, to Moche culture. Although Roman Catholic church authorities after the Spanish conquest attempted to suppress its use, this failed, as shown by the Christian element in the common name "San Pedro cactus" - Saint Peter cactus. The name is attributed to the belief that just as St Peter holds the keys to heaven, the effects of the cactus allow users "to reach heaven while still on earth."
Alkaloids
The San Pedro cactus contains a number of alkaloids, including the well-studied chemical mescaline (0.21-1.8%), and also 3,4-dimethoxyphenethylamine, 3-Methoxytyramine, 4-hydroxy-3-methoxyphenethylamine, 4-hydroxy-3,5-dimethoxyphenethylamine, anhalonidine, anhalinine, hordenine, tyramine, and 3-methoxytyramine.
Mescaline (3,4,5-trimethoxyphenethylamine) is a psychedelic drug and entheogen, which is also found in some other species of genus Echinopsis (i.e. Echinopsis lageniformis, Echinopsis peruviana, and Echinopsis scopulicola) and the species Lophophora williamsii (peyote).
Anecdotal evidence suggests that the highest concentration of active substances is found in the layer of green photosynthetic tissue just beneath the skin.
There are various mescaline extraction techniques, simple (simmering in water 5 to 7 hours) and complex (such as an acid-base extraction), the latter technique yielding a material with a significantly higher concentration of mescaline.
Cultivation
The San Pedro cactus grows in USDA hardiness zones 8b to 10.
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.
Propagation
Like many other plants, Echinopsis pachanoi can be propagated from cuttings. The result is a genetic clone of the parent plant. A long cactus column can be also laid on its side on the ground (like a log), and eventually roots will sprout from it and grow into the ground. After time, sprouts will form and cactus columns will grow upward out of it along its length.
Legality
In most countries it is legal to cultivate the San Pedro cactus, but in countries where possession of mescaline and related compounds is illegal and highly penalized, cultivation for the purposes of consumption is most likely illegal and also highly penalized. This is the case in the United States, Australia, Canada, Sweden, Germany, New Zealand, and Norway, where it is currently legal to cultivate the San Pedro cactus for gardening and ornamental purposes, but not for consumption.
