Texas’ Peyote Hunters Struggle to Find a Vanishing, Holy Crop

Mauro Morales picks his way through mesquite trees and prickly pear cacti. The 65-year-old cautiously steps around a thicket of tasajillo, or rattail cactus, just down the road from his small ranch near Rio Grande City. Tasajillo thorns stick you like a fish hook, he says. Then there’s the cola seca—the rattlesnake—another job hazard.

“We’re far enough from a hospital that you probably wouldn’t make it if you got bit,” he says in a quiet voice, as though a snake might take his words as an invitation to strike.

Morales has been wandering through the chaparral for half an hour, staring at the ground. He combs over small rocks with a stick. Finally, he spots a greenish knob, sprouting out of the ground under the tasajillo thicket.

“There’s some medicine, right there,” he says. It’s a lone peyote button, about an inch in diameter, way too small to harvest. It’ll be another five years before this peyote is mature. As he navigates the hostile flora, he points to three more small peyote plants, all of them too young to cut.

“I used to collect as much in a week as I now do in a month,” he says. “I don’t know what’s going to happen to the medicine.”

Cruising the Amazon

Life is everywhere in the upper Amazon wilderness. Life that creeps, life that crawls, life that slithers, sprouts, burrows, scurries and slinks—and dies. The dank odors of alternating rot and genesis rise from the mulching forest floor. My Deet-fortified insect spray battles swarms of blood-mad mosquitoes to a draw. The air is fat with syrupy humidity, and I am sweating like an icicle in the sun.

Nature is on fast-forward here. Trees—palms, laurels, kapoks, mahoganies, bamboos, acacias, figs, balsas, cedars—jostle each other in the search for a share of the sunlight; they grow to enormous heights and spread their foliage like a green umbrella at the top. Lianas, tropical climbing plants, wind themselves like boa constrictors around the tree trunks and arch themselves in great loops as they, too, struggle upward for a glimpse of light. The trees become parasites, and giant orchids seed themselves in branches 60 feet from the ground. The general effect is of a an impenetrable fecund, living wall.

Amid this vast assortment of life, creatures use stunts and flim-flam to befuddle or repel predators, lure prey, seduce mates and gobble food. Caterpillars masquerade as snakes, plants imitate the smell of rotting meat to attract flies as pollinators, and trees rely on fish to distribute their seeds when the rivers flood.

It’s a jungle out here.

Amazon Natives Use Google Earth, GPS To Protect Rainforest Home

Deep in the most remote jungles of South America, Amazon Indians (Amerindians) are using Google Earth, Global Positioning System (GPS) mapping, and other technologies to protect their fast-dwindling home. Tribes in Suriname, Brazil, and Colombia are combining their traditional knowledge of the rainforest with Western technology to conserve forests and maintain ties to their history and cultural traditions, which include profound knowledge of the forest ecosystem and medicinal plants. Helping them is the Amazon Conservation Team (ACT), a nonprofit organization working with indigenous people to conserve biodiversity, health, and culture in South American rainforests.

Marijuana’s Key Ingredient Might Fight Alzheimer’s

The active ingredient of marijuana could be considerably better at suppressing the abnormal clumping of malformed proteins that is a hallmark of Alzheimer’s than any currently approved drugs prescribed for the treatment of the disease.

Scientists report the finding in the Oct. 2 issue of the journal Molecular Pharmaceutics.

About 4.5 million Americans suffer from Alzheimer’s disease, which gradually destroys memory. As more people survive into old age, cases of Alzheimer’s disease are expected to triple over the next 50 years. There is no known cure.

The researchers looked at THC, the compound inside marijuana responsible for its action on the brain. Computer models suggested THC might inhibit an enzyme with the tongue-twisting name of acetylcholinesterase (also called AChE) that is linked with Alzheimer’s. AChE is known to help accelerate the formation of abnormal protein clumps in the brain known as amyloid plaques during Alzheimer’s. This enzyme also helps break down the brain chemical acetylcholine, which is linked to memory and learning. Acetylcholine levels are reduced during Alzheimer’s.

In lab experiments, the scientists found THC was significantly better at disrupting the abnormal clumping of malformed proteins. THC could completely prevent AChE from forming amyloid plaques, while two drugs approved for use against Alzheimer’s, donepezil and tacrine, reduced clumping by only 22 and 7 percent, respectively, at twice the concentration of THC used in the tests.

Chocolate generates electrical power

Willy Wonka could have powered his Great Glass Elevator on hydrogen produced from his chocolate factory.

Microbiologist Lynne Mackaskie and her colleagues at the University of Birmingham in the UK have powered a fuel cell by feeding sugar-loving bacteria chocolate-factory waste. “We wanted to see if we tipped chocolate into one end, could we get electricity out at the other?” she says.

The team fed Escherichia coli bacteria diluted caramel and nougat waste. The bacteria consumed the sugar and produced hydrogen, which they make with the enzyme hydrogenase, and organic acids. The researchers then used this hydrogen to power a fuel cell, which generated enough electricity to drive a small fan (Biochemical Society Transactions, vol 33, p 76).

Beverage Creates a Buzz

INZA, Colombia — Call it the “Real Thing.”

Indians in this remote mountain village in southern Colombia are marketing a particularly refreshing soft drink that harks back to Coca-Cola’s original formula, when “coca” was in the name for a reason.

Advertising posters here describe the carbonated, citrus-flavored Coca-Sek as “more than an energizer” — a buzz that just might be provided by a key ingredient, a syrup produced by boiling coca leaves.

Since January, the Nasa indigenous community has been offering the soft drink locally and in neighboring Popayan, where it is bottled. By the end of the year, the Nasa hope to sell Coca-Sek nationwide, targeting the same consumers who drink Gatorade or Red Bull, both highly popular with Colombians.

For six years, the Nasa have been quietly selling coca-flavored cookies, aromatic teas, wines and ointments at informal sidewalk stalls and in health food stores. They say they’re trying to capitalize on a plentiful resource — and remove the stigma from a leaf that for them is sacred.

Test for Magic Mushrooms Glows in Dark

An Australian researcher has developed a new test for mushrooms that produces a glowing light if they contain the hallucinogenic ingredients that make them ‘magic’.

Several species of magic mushroom grow in Australia, mainly in New South Wales, Victoria and South Australia.

Nicole Anastos, who did the research for her PhD at Deakin University, describes her work in the latest issue of the Journal of Forensic Sciences.

She applied the method to three species of magic mushroom Psilocybe subaeruginosa, Hypholoma aurantiaca and Panaeolina foenisecii, provided by the Royal Botanic Gardens Melbourne.

The technique uses chemiluminescence, a light reaction that occurs when two chemicals react, to detect psilocybin and its metabolite psilocin. These are the serotonin-like psychoactive ingredients in magic mushrooms.

Study boosts homeopathy

A six-year UK study has provided support for homeopathy by demonstrating that over 70% of people with chronic diseases had positive health changes after homeopathic treatment.

The study, conducted at Bristol Homeopathic Hospital shows, involved more than 6,500 patients with conditions ranging from eczema to arthritis.

The results come a few months after a study in The Lancet found that homeopathy was no better than placebo.

In a BBC News report, Matthias Egger of the University of Berne, who worked on The Lancet study, criticized the new report.

Egger says it was weakened by lack of a comparison group and he questioned the validity of how improvements were recorded.

“Patients were simply asked by their homeopathic doctor whether they felt better, and it is well known that in this situation many patients will come up with the answer the doctor wants to hear,” says Egger.

The Doors of Perception by Aldous Huxley

It was in 1886 that the German pharmacologist, Louis Lewin, published the first systematic study of the cactus, to which his own name was subsequently given. Anhalonium lewinii was new to science. To primitive religion and the Indians of Mexico and the American Southwest it was a friend of immemorially long standing. Indeed, it was much more than a friend. In the words of one of the early Spanish visitors to the New World, “they eat a root which they call peyote, and which they venerate as though it were a deity.”

Why they should have venerated it as a deity became apparent when such eminent psychologists as Jaensch, Havelock Ellis and Weir Mitchell began their experiments with mescalin, the active principle of peyote. True, they stopped short at a point well this side of idolatry; but all concurred in assigning to mescalin a position among drugs of unique distinction. Administered in suitable doses, it changes the quality of consciousness more profoundly and yet is less toxic than any other substance in the pharmacologist’s repertory.

Mescalin research has been going on sporadically ever since the days of Lewin and Havelock Ellis. Chemists have not merely isolated the alkaloid; they have learned how to synthesize it, so that the supply no longer depends on the sparse and intermittent crop of a desert cactus. Alienists have dosed themselves with mescalin in the hope thereby of coming to a better, a first-hand, understanding of their patients’ mental processes. Working unfortunately upon too few subjects within too narrow a range of circumstances, psychologists have observed and catalogued some of the drug’s more striking effects. Neurologists and physiologists have found out something about the mechanism of its action upon the central nervous system. And at least one Professional philosopher has taken mescalin for the light it may throw on such ancient, unsolved riddles as the place of mind in nature and the relationship between brain and consciousness.

Entheogenic Linkage

The Psychedelic Salon has posted a new podcast, this one being a dialogue between Terence McKenna and Ralph Abraham.

From the site: It isn’t often that we have the opportunity to see how accurate predictions about the future are, but this fascinating conversation between two of the great thinkers of our times has already proven to be right on target. The reason this may be of interest to you is that if they correctly predicted some things that have now happened, then we are really in for some big time excitement if some of their more far-out predictions come true.

Also, last night on Coast to Coast AM with George Noory, the author Graham Hancock was interviewed. Although it’s mostly new-age nonsense, he echoes Terence Mckenna’s claim that our cognitive and linguistic capabilities were enhanced through the use of entheogens.

Marijuana Chemical Fights Hardened Arteries

April 6, 2005—The active ingredient in marijuana that produces changes in brain messages appears to fight atherosclerosis—a hardening of the arteries.

But puffing pot probably won’t help. The findings, reported in the journal Nature, “should not be taken to mean that smoking marijuana is beneficial for the heart,” says Michael Roth, MD, a professor of medicine at UCLA medical school.

New research opens a window on the minds of plants

RALEIGH, N.C. ? Hardly articulate, the tiny strangleweed, a pale parasitic plant, can sense the presence of friends, foes, and food, and make adroit decisions on how to approach them.

As trowel-wielding scientists dig up a trove of new findings, even those skeptical of the evolving paradigm of “plant intelligence” acknowledge that, down to the simplest magnolia or fern, flora have the smarts of the forest. Some scientists say they carefully consider their environment, speculate on the future, conquer territory and enemies, and are often capable of forethought – revelations that could affect everyone from gardeners to philosophers.

The Beer Brewing Monkeys of Borneo

Long thought the figment of sailors? over-active imaginations, recent studies have proven the existence of savvy primates who know how to make fermented brew and throw one hell of a party.

Giles Humbert III quizzes Dr. Roger Curlman, the award-winning British anthropologist who spent six months living with the drunken and savage beasts.

Modern Drunkard Magazine: Monkeys that make their own beer! Inconceivable!

Richard Curlman: Not beer, actually. That?s a long-standing misconception. It?s more of a crude sort of wine.

MDM: A particularly nasty brand of Cabernet, I should imagine.

RC: Nothing that sophisticated.

Chomp, chomp: Carrot compound reduces cancer risk

Scientists have given us another reason to eat carrots—a compound found in the popular root vegetable has been found to have an effect on the development of cancer. A team of researchers, from the University of Newcastle upon Tyne in England and Denmark, found the natural pesticide falcarinol reduced the risk of cancer developing in rats by one third. Although experts have recommended that people eat carrots for their anti-cancer properties, it has not been known exactly what component of the vegetable has this effect.
