What’s the deal with … coffee enemas?

It seems like nothing is off limits these days in L.A.’s most woo-woo wellness scenes. From ayahuasca circles and mail-order ketamine lozenges to off-label peptide injections, IV drips and longevity treatments, there’s a seemingly infinite number of ways to look and feel better that people will swear by in this town. Coffee enemas — mostly for digestive issues, but also for a host of other emotional and physiological conditions — is on that alleged miracle menu, and far more common than I even realized before I started writing this article.

“Oh, I have a friend who does that,” “Oh, my cousin swears by it,” I began hearing from people as soon as I started looking for interviewees.

Reddit contains hundreds of anecdotes — both enthusiastic and cautionary — about coffee enemas, which involve a person, often on their own, but sometimes with the assistance of an alternative health practitioner, filling a bag with coffee fluid, inserting a tube into their rectum, and slowly allowing the liquid to be absorbed. “Beware of coffee enemas,” reads the subject line of a post from a woman who did them regularly for a decade and reports feelings of exhaustion, spaciness and cravings when she tries to stop. “Caffeine in any form only (temporarily) masks and provides salve toward bigger, unaddressed issue(s),” she writes.

In response, another user — a person with Stage 4 ovarian cancer — jumps in to defend the practice. “Let’s respect what we are all doing, whether we agree or not,” they write. “I am doing conventional [treatment] in conjunction with alternative (I believe there is a place for both). I haven’t felt this good since my diagnosis. I feel light, have never felt jittery and chemotherapy had me so constipated I would cry.”

Over the last couple of decades, the interest in digestive health has grown exponentially, prompted by research on the gut-brain connection. According to a report by Grand View Research, the global gut health market was valued at $60.31 billion in 2025 and is projected to reach $114.83 billion by 2033. The growing number of people who are quietly (and often devoutly) doing coffee enemas is a part of this larger trend, which also includes fasting, cleanses, colonics, probiotics, food allergy and stool tests, and a number of other products and services intended to address everything from irregular or uncomfortable bowel movements to energy levels and mood. But what’s the deal with coffee enemas? And are they actually good for you? We talked to a wide range of people with an equally wide range of opinions.

Five enemas a day? Inside the controversial Gerson therapy

The pro-enema Reddit user coping with Stage 4 cancer posted that they do three coffee enemas daily. They discovered the practice through Gerson, an institute founded in 1978 to promote a treatment plan initially developed for tuberculosis, and later for cancer, migraines and other chronic conditions, by German American physician Dr. Max Gerson in the 1930s. If you visit the Gerson Institute website, the supplies for a coffee enema — organic therapy blend coffee ($9.75) and the complete enema bucket kit with catheter ($19) — are listed in its store. It has clinics in Tijuana, Budapest and Shangri-La, China.

Nicole Ferrer-Clement, executive director of the Gerson Institute, says the treatment plan, referred to as the Gerson therapy, has four parts, with five coffee enemas per day being the first part and an essential component of the protocol. The other parts include a vegetarian, fat-free diet, three juices (carrot, carrot and apple, and a green juice) and supplements. The idea behind the coffee enemas, she says, is that compounds (theobromine, theophylline, caffeine) in coffee stimulate the liver to produce more bile, which helps carry toxins out of the body through the digestive tract. Ferrer-Clement says this is important for cancer patients, whose livers may already be compromised while processing toxins released during treatment. Even though many people reach out to Gerson about coffee enemas for general health and wellness and constipation, she says that’s not generally something they recommend. The therapy remains controversial among mainstream oncologists, in part because there are few rigorous clinical studies evaluating its efficacy.

“We want research on [coffee enemas], we’re happy and open to do that, if someone is going to fund it,” Ferrer-Clement says, estimating the institute has treated thousands of patients over the years.

In addition to using coffee enemas to treat cancer, the majority of users online report turning to them for constipation. Many anecdotes are from people who tried more conventional medicine for digestive issues and, from a place of desperation, decided to look elsewhere for solutions. Others, like Chevanni Davids, a 33-year-old South African man living in Bali, use them to maintain a general sense of well-being. Davids — who grew up in South Africa, where culturally it’s common for grandmothers to administer enemas to children in rural areas — does a coffee enema twice per month. He was introduced to the practice of enemas with coffee by someone he describes as a Brazilian grandmother or elder. He swears by the practice, saying it’s kept his bowel movements regular and his emotional state at an equilibrium. Davids warns against doing them too frequently, however. “The addiction is a thing,” he says, “because it feels so, so good. After you do it once, you’re going to say, ‘I’m going to do that tomorrow.’”

A doctor’s take

Unsurprisingly, given that most people tend to find coffee enemas after reports of being failed by Western medicine, mainstream gastroenterology is not on board with this practice. “Coffee enemas are based on the ill-conceived idea that you’re washing toxins out of your colon, but your colon is not an organ that clears toxins like the liver,” says Dr. Barry Zamost, a gastroenterologist who was in private practice in Long Beach for more than 40 years. “This just flies in the face of all logic and physiology that any doctor has learned for 100 years.”

Zamost remembers first hearing of coffee enemas decades ago when Michael Landon, an actor best known for his roles on “Little House on the Prairie” and “Bonanza,” decided to reject chemotherapy in favor of alternative treatments following a pancreatic cancer diagnosis in 1991. Over his four decades in private practice, Zamost says he frequently saw patients with constipation who were frustrated and trying alternate methods, but that oral therapies such as laxatives, supplements and prescription medications remain the most safe and effective treatments.

A review of case reports from nine people who self-administered coffee enemas also concluded that there’s insufficient evidence to prove that the practice is helpful, and that it could be harmful, to the colon. Zamost says he thinks it’s unlikely for someone to cause themselves serious harm by doing coffee enemas, although it’s happened. He also says that in rare cases that enemas — not with coffee — are appropriate for patients who are severely constipated to provide temporary relief. But, generally, he doesn’t see any benefit to using coffee. As for why people report loving them? That’s easy enough to explain, he says. “Everybody feels better after a bowel movement. So if you gave yourself an enema that really made you feel like you were emptied, you’ll feel good. It doesn’t mean your health is better.”

The takeaway

Coffee enemas are likely not harmful when done in moderation, but we don’t have much more than anecdotal evidence at this point to indicate that they’re helpful either.

Nobel Prize winner leaving UC Berkeley for new role in China

Nobel Prize winner leaving UC Berkeley for new role in China

Nobel Prize recipient Omar Yaghi is leaving his role at UC Berkeley to lead the development of a new artificial intelligence institute at Tsinghua University in Beijing, the Chinese university announced.

Yaghi will head the AI Chemistry and Materials Research Institute at Tsinghua, where he was appointed an honorary professor in 2022. Known as AIMATRY (AI × Materials × Chemistry), the new center will focus on material design and synthesis through artificial intelligence, according to a statement from the university.

In 2025, Yaghi shared the Nobel Prize in chemistry with Susumu Kitagawa of Kyoto University and Richard Robson of the University of Melbourne for their development of metal-organic frameworks, a type of super-porous material in which metal ions and carbon-based molecules combine to form crystals with exceptionally large surface areas.

The material has the potential to combat climate change by capturing and storing carbon or other pollutants, and by extracting water from the atmosphere in water-scarce areas. Upon awarding the prize, a member of the Nobel committee likened the technology’s ability to store enormous amounts of stuff in seemingly compact spaces to Hermione Granger’s enchanted handbag in the Harry Potter series.

Yaghi’s Irvine-based company, Atoco, has said it will start taking orders later this year for its technology that harvests water from the air.

A representative for Yaghi said he was not yet available to respond to questions.

China is one of several countries that has been actively recruiting scientists from the U.S., where the Trump administration has slashed science funding, suspended research grants, fired science advisors and tightened immigration restrictions.

“For many, many years, our funding was very competitive; if you worked hard and you were doing good research, you would get funding,” Yaghi said of the U.S. in an interview with Scientific American earlier this year. “The current state is not so encouraging because of the cutting back on grants and support of science by the very agencies that many university researchers rely on.”

Yaghi was born in Jordan to Palestinian refugees, and immigrated to the U.S. when he was 15 to study.

“We’ve learned over and over in human civilization that scholars can move across borders,” Yaghi told the New York Times last year. “This is how knowledge spread and how vast regions of the world lifted themselves out of poverty.”

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

Trump administration seeks to limit federal funding that doesn’t ‘advance’ presidential policies

A new rule proposed by the White House Office of Management and Budget would fundamentally overhaul the way federal grants are awarded and overseen — a sweeping change that one scientific society said “would all but end the use of scientific merit in the selection of grants and programs across the government.”

Proposed in late May, the rule would give political appointees unprecedented control over federal grants for research, education and infrastructure, and specifies that government funds can only be spent on projects “aligned with administration policies and priorities,” according to a copy of the proposed rule.

The rule would also restrict research topics, limit U.S. scientists’ ability to collaborate with colleagues in other countries and make it easier for the government to suspend or cancel grants at any time.

The changes are intended to improve “transparency, accountability, and oversight for Federal awards” while “ensuring that American tax dollars are not wasted or misused,” according to the White House office.

But critics say that if the rule is implemented, the final sign-off for grants will no longer be in the hands of subject-matter experts within individual agencies, but in those of political appointees.

“This touches all parts of American life,” said Dr. Eric Rafla-Yuan, a psychiatrist who practices at the Veterans Administration and San Diego County’s psychiatric hospital.

“Control of how all of the federal grants and programs are funded will fall under a small group of highly partisan individuals who would have very few limits on how they spend these billions of taxpayer dollars,” said Rafla-Yuan, who also chairs the Committee to Protect Public Mental Health advocacy group. “This touches everyone’s life, even if they don’t realize it.”

OMB published the proposed rule May 29, opening a 45-day comment period that closes July 13.

Opposition to the proposed rule has mobilized multiple sectors of society. Professional groups representing cancer researchers, civil engineers, county governments, medical schools, housing agencies, city and municipal governments, nonprofits and others have publicly expressed concerns about potential consequences.

By midday Thursday, the Federal Register logged nearly 100,000 comments about the proposal, many of them expressing concern.

“I understand the need for oversight, fiscal responsibility, and accountability. That is not the issue,” wrote Jack Feldman, a neuroscientist who holds the David Geffen School of Medicine Chair in Neuroscience at UCLA. “The issue is whether scientific research is to be judged by scientific merit, or whether it can be approved, denied, or terminated according to broad political criteria that may change from one administration to the next.”

Crucially, the rule converts policies governing federal grants from “guidance” into binding regulations that all agencies would be required to follow. It would give political appointees power to override federal agencies’ merit-based reviews and mandate that a political appointee review decisions to ensure that all awards “demonstrably advance the President’s policy priorities.”

The elevation of political appointees in what were previously merit-based decisions has alarmed many scientists.

“The proposed rule changes would all but end the use of scientific merit in the selection of grants and programs across the government,” read a statement from the Planetary Society, a nonprofit dedicated to space research.

Researchers and science groups have also expressed concern about a section of the rule prohibiting the promotion of “theories of disparate-impact liability” — a legal concept that refers to policies that appear neutral but cause disproportionate harm to certain groups.

The section’s vague language and many loopholes could have a chilling effect on any research that studies the effects of a disease, policy or public health intervention on any specific group of people, Rafla-Yuan said.

As an example, he said, “if there’s a specific age range that is at higher risk for suicide, and we want to figure out, well, what’s going on with people that are aged 14 to 19 … we can’t do that under the wording in this rule.”

New restrictions on collaborations with scientists in other countries would hinder opportunities for U.S. researchers and limit innovation, said Joanne Padrón Carney, chief government relations officer for the American Assn. for the Advancement of Science.

“Science is a global enterprise. Especially in biomedical and public health fields, diseases don’t care about borders or government policies,” she said.

California’s congressional delegation sent a letter Wednesday asking OMB to rescind the proposal, outlining concerns about its impact on scientific innovation, U.S. competitiveness and the fiscal stability of local governments, many of which rely on federal grants for local services.

The proposed rule grants the federal government broad powers to suspend or cancel grants for any reason, introducing “unprecedented unpredictability into local governance,” the lawmakers wrote, “leaving vital infrastructure projects unfinished and abandoning vulnerable populations who rely on these services.”

Republican Sen. Susan Collins has also asked the White House to withdraw certain parts of the letter and extend the public comment period, saying the proposed rule as written would “harm small and rural communities, undermine scientific and biomedical research, and conflict with Congress’ control over the federal funding process.”
