A prestigious academic indexing service has removed Cureus, a medical journal that publishes a disproportionately high volume of alternative medicine research, from its Master Journal List due to concerns about article quality and peer review standards. This decision signals a growing problem in how complementary and integrative medicine research reaches the publicâand why patients should be cautious about which studies they trust. What Happened to Cureus and Why It Matters? Clarivate, the company that maintains the Web of Science databaseâone of the most widely used academic research indexesâremoved Cureus from its Master Journal List in March 2026. This means the journal will no longer receive an impact factor, a metric that researchers use to evaluate a journal's credibility. The decision came after Clarivate placed the journal on hold in September 2025 due to concerns about article quality. The removal is significant because it directly affects how researchers and healthcare providers perceive published studies. When a journal loses indexing, researchers are less likely to submit their work there, and clinicians are less likely to cite or trust its findings. For patients seeking evidence-based information about alternative therapiesâfrom acupuncture to herbal supplementsâthis raises an important question: How did a journal with such serious quality problems become a major publisher of complementary medicine research in the first place? The Scale of the Problem at Cureus Cureus published approximately 50,000 papers in 2025 alone, an extraordinarily high volume for a single journal. What makes this concerning is that an unusually high percentage of these articles focus on so-called alternative medicine, or complementary and integrative medicine. The journal's retraction rateâthe percentage of published papers that must be withdrawn due to errors, plagiarism, or fraudâappears to be significantly higher than the average for medical journals. Since Springer Nature acquired Cureus in late 2022, the journal has retracted approximately 125 papers. In 2025 alone, Cureus closed six of its academic channels that critics described as functioning like "paper mills"âoperations that prioritize publishing volume over quality. The journal has also repeatedly had to retract plagiarized articles and has faced serious authorship issues, including cases where authors faked peer reviewer accounts or failed to disclose conflicts of interest. Why Does This Matter for Alternative Medicine Research? Alternative therapiesâincluding acupuncture, herbal remedies, meditation, tai chi, and supplementsâare increasingly popular among patients seeking holistic, personalized care. Many people use these approaches alongside conventional medicine or to manage chronic conditions like back pain, anxiety, and arthritis. The problem is that not all alternative medicine research is created equal, and low-quality studies can mislead patients into trying ineffective or potentially harmful treatments. When a journal like Cureus publishes large volumes of alternative medicine papers without rigorous peer review, it creates a false sense of legitimacy. A patient searching online for evidence about a particular herb or therapy might find a Cureus article that appears to be peer-reviewed research, when in fact it may not have undergone adequate scientific scrutiny. This is especially dangerous when alternative therapies are used instead of proven conventional treatments for serious conditions. How to Evaluate Alternative Medicine Research Safely - Check the Journal's Reputation: Look for articles published in well-established, indexed journals with strong peer review processes. Avoid journals that have been flagged for quality concerns or removed from major academic databases like Web of Science. - Look for Randomized Controlled Trials: The strongest evidence comes from randomized controlled trials and systematic reviews that combine multiple studies, not from case reports or opinion pieces. Ask your healthcare provider whether the research supporting a therapy meets this standard. - Evaluate the Outcome Being Measured: A study might show that a treatment is "statistically significant" but provide only a small practical benefit. For example, a supplement might reduce pain by 10% in a study, which may not be meaningful in real life. Consider whether the benefit matters for your specific situation. - Assess the Risk-Benefit Profile: Even natural treatments can cause side effects or interact with medications. A therapy with weak evidence but high risk is not worth trying, while a therapy with moderate evidence and low risk might be reasonable to try alongside conventional care. - Distinguish Between Complementary and Alternative Use: Using acupuncture alongside chemotherapy for nausea (complementary) is different from using it instead of insulin for diabetes (alternative). Complementary approaches are generally safer because they support rather than replace proven treatments. What Does the Evidence Actually Show for Common Alternative Therapies? Not all alternative medicine research is unreliable. Some therapies have accumulated solid evidence for specific uses. According to integrative medicine experts, several approaches have stronger evidence bases than others: Acupuncture has the most robust evidence for treating certain types of chronic pain, including low back pain, neck pain, and osteoarthritis-related pain. It also shows promise for tension-type headaches and migraines when used for prevention. The mechanism likely involves modulation of pain pathways and release of endogenous opioidsâthe body's natural pain-relieving chemicals. Mindfulness, meditation, and breathing practices have strong evidence for reducing stress and anxiety symptoms, improving sleep, and helping people manage chronic illness. These approaches can enhance quality of life and reduce how much pain disrupts daily activities. Movement-based therapies like yoga and tai chi show good evidence for chronic low back pain, balance improvement in older adults, and stress reduction. Tai chi, in particular, has strong evidence for fall prevention in seniors. Massage therapy can provide short-term relief from muscle tension and anxiety, and may help reduce symptom-related distress in cancer patientsâthough it is not a cancer treatment itself. Herbal supplements present a more complicated picture. While some herbs like peppermint oil show promise for irritable bowel syndrome symptoms and ginger may help with nausea, quality assurance, dosing uncertainty, and drug interactions remain major concerns. The Bottom Line: How to Use Alternative Medicine Safely The removal of Cureus from major academic indexes serves as a reminder that not all published research is trustworthy. When considering alternative or complementary therapies, work with your primary healthcare provider to evaluate the evidence together. Ask whether a therapy is being used to complement proven treatments or replace themâthe distinction matters enormously for your safety. Look for therapies with solid evidence from reputable journals, understand what outcome is actually being measured, and be honest about the risks. Some alternative approaches, like meditation for anxiety or acupuncture for back pain, have accumulated enough good evidence to be worth trying alongside conventional care. Others remain unproven or carry significant risks. The goal of integrative medicine is not to replace proven healthcare, but to support informed decisions with the best available evidenceâand that evidence should come from sources you can trust.
