Partly. Her everyday basics (whole grains, less sugar, honey for a cough) are well supported [1][2]. Most of her poultices, packs and soaks have little or no research, and a few claims are dangerous. The NSW health regulator permanently prohibited her from providing health services in 2019, finding she posed a risk to public health and safety [6].","mediumText":"How to read her advice\n\nHer teaching is food-first. It rests on the idea that the body heals itself when it gets the right conditions: whole plant foods, water, sunlight and sleep, plus water treatments such as hot-and-cold showers and soaks, and kitchen-cupboard poultices and packs. It helps to sort the advice into what holds up, what is thin or traditional, and what a regulator has acted on.\n\nWhat holds up. Whole grains instead of white flour went with lower rates of heart disease, cancer death and early death across 45 long-term studies [1]. Plant-rich eating, less added sugar, enough sleep and daily daylight are standard advice too (see plant-based diets, added sugar, sleep and sunlight). Honey probably eases cough in children over one year old [2], ginger may ease nausea [11], and aloe vera gel may speed the healing of burns [12].\n\nWhat is thin or traditional. Castor-oil packs, charcoal poultices, onion and potato poultices, hot-and-cold showers and Epsom-salt soaks are folk comfort measures. Warmth can soothe, but the research is small. One before-and-after study found castor-oil packs eased straining without changing how often people went [3], and we found no trials showing that charcoal or onion draws out venom, infection or toxins. Our articles on poultices and compresses, castor oil packs, activated charcoal, hydrotherapy and Epsom salt baths cover each.\n\nThe regulatory record. The NSW Health Care Complaints Commission (HCCC) describes O'Neill as an unregistered practitioner who provides services as a naturopath, nutritionist and health educator. On 24 September 2019 it found that she had breached five clauses of the Code of Conduct for Unregistered Health Practitioners and posed a risk to the health and safety of the public, and it made a permanent order prohibiting her from providing any health service, paid or voluntary [6]. Its statement quoted comments from her publications that it called non-evidence-based: that raw goat's milk can replace breast milk, that cancer is a fungus treatable with bicarbonate soda, that pregnant women with group B strep need not take antibiotics, and that there are no safe vaccines [6]. It also found that she discourages mainstream treatment for cancer, antibiotics and vaccinations [6]. The HCCC's register still listed the order as permanent when we checked on 21 October 2026 [13]. Orders can change, so check the register for the current position.\n\nUsing this page. The grades below apply to the uses she describes. They draw on public lecture listings, transcripts, her online shop and regulator documents, and accounts of her preparations vary, so this page gives no recipes or doses. For sick-day basics see what to eat when sick and fever; for whole-food cooking, browse the recipe library.","deepText":"The remedies, one by one\n\nGrades describe the use she recommends, not the substance in general. \"We found no trials\" means PubMed searches on 21 October 2026 found none for that use.\n\nStrong\n\nWhole grains instead of white flour. In a meta-analysis of 45 prospective studies, each extra 90 g a day (about three servings) went with 22% lower risk of cardiovascular disease, 15% lower cancer mortality and 17% lower all-cause mortality; refined grains showed little link [1]. The data are observational. Her other diet principles, mostly plants and little refined sugar, are also well supported (plant-based diets, added sugar).\n\nModerate\n\nHoney (cough, sore throat, colds; her onion-honey syrup). A Cochrane review of six trials (899 children aged 12 months to 18 years) found honey probably eased cough more than no treatment or placebo, and may match dextromethorphan; most children were treated for one night, and the reviewers saw no strong evidence for or against it [2]. We found no trial of the onion. Honey can carry Clostridium botulinum spores: a 1979 investigation found them in 9 of 90 samples and linked honey to infant botulism, so it should not be fed to infants [7]. More in honey.\n\nGinger tea. A review of 109 trials found consistent support for easing nausea and vomiting in pregnancy and for effects on inflammation, metabolic and digestive outcomes; only 43 trials were high quality, and other uses were controversial [11]. We found no trial for colds or flu. More in ginger.\n\nAloe vera gel (burns). A meta-analysis of nine trials (six with healing data) found aloe shortened healing of second-degree burns by about 3.8 days against other topical treatments, with no clear difference in pain or infection [12]. Cool a burn under running water first; large, deep or facial burns, and burns in children, need medical care. More in aloe vera.\n\nSleep, sunlight and water are sound habits with support for specific benefits (sleep, sunlight); sun exposure also raises skin-cancer risk, so follow local sun-protection advice.\n\nWeak\n\nCastor-oil packs (constipation, 'lumps', cysts). The only clinical study we found was a before-and-after study in two Turkish rest homes with no separate comparison group described: packs did not change how often people went but eased straining, stool hardness and incomplete emptying [3]. We found no trials for lumps, cysts, fibroids, tumours, gallstones or bone spurs.\n\nPotato poultice (swollen fingers and ankles, splinters, puncture wounds). The one trial we found randomised 62 patients with forearm swelling after a heart procedure through the wrist artery to a raw potato compress or a standard medicated compress; the potato group had less swelling and pain [4]. That is a narrow hospital setting with an active comparator, not a test of infected fingers, sprains or wounds.\n\nActivated charcoal by mouth (poisoning, gas, 'food poisoning'). Hospitals use charcoal for some recent overdoses. In a crossover study of six healthy volunteers per drug, one 50 g dose cut absorption of two anti-seizure drugs sharply (lamotrigine to 58%, oxcarbazepine to 2.8% of usual exposure) [10]. That was an overdose-type dose, so it does not show what capsules do, but it is why people on prescription medicines should ask a pharmacist first. Suspected poisoning needs your local poisons centre. More in activated charcoal.\n\nContrast showers, Epsom soaks and the 'flu bomb' (a hot drink of garlic, ginger, lemon, honey and cayenne, promoted for colds and flu; recipes vary). Warm baths soothe, but the case that hot-and-cold showers or magnesium absorbed through the skin treat illness is weak (hydrotherapy, Epsom salt baths). We found no trial of the flu bomb as a mixture; its honey has the best evidence, and claims that it cures flu are unsupported. Never swallow essential oils; cayenne, garlic or ginger packs can burn skin, especially numb skin.\n\nNone\n\nCharcoal and onion poultices (venom, stings and infections; earache, boils and chest colds). We found no human trials of either. A poultice must never delay care for a snake bite, a sting that swells the face, a spreading infection, or earache in a small child; see poultices and compresses.\n\nContradicted\n\nA salt crystal before each glass of water, offered as the quickest way to hydrate and as help for high blood pressure. Trials of cutting sodium show lower blood pressure, so adding salt runs the wrong way (sea salt, blood pressure).\n\nClaims to leave alone\n\nThe HCCC listed four examples of comments from her publications. Each concerns serious illness, and acting on them in place of care can cause harm.\n\n'Cancer is a fungus', treated with bicarbonate soda, diet or wraps. Cancer is the growth of the body's own cells, not a fungus, and we found no trial showing that bicarbonate soda, taken or applied, treats the cancer itself. The evidence does show the cost of replacing proven treatment: in a matched cohort, 280 people with non-metastatic breast, prostate, lung or colorectal cancer who chose alternative medicine alone had 2.5 times the risk of death of 560 matched patients who had conventional treatment (hazard ratio 2.50, 95% CI 1.88 to 3.27). The study is observational, and choosing alternative medicine alone was rare [5].\n\nRaw goat's milk for babies. In US dairy outbreaks from 1993 to 2006, unpasteurised products caused 60% of those with known pasteurisation status and about 150 times more outbreaks and illness per unit consumed, with people under 20 disproportionately affected [8]. Babies who are not breastfed need a regulated infant formula; goat's-milk formulas exist and are a different product. …","deepTruncated":true,"references":[{"id":"1","title":"Whole grain consumption and risk of cardiovascular disease, cancer, and all cause and cause specific mortality: systematic review and dose-response meta-analysis of prospective studies","authors":"Aune D, Keum N, Giovannucci E, et al.","year":2016,"journal":"BMJ","pmid":"27301975","url":"https://pubmed.ncbi.nlm.nih.gov/27301975/"},{"id":"2","title":"Honey for acute cough in children","authors":"Oduwole O, Udoh EE, Oyo-Ita A, et al.","year":2018,"journal":"Cochrane Database Syst Rev","pmid":"29633783","url":"https://pubmed.ncbi.nlm.nih.gov/29633783/"},{"id":"3","title":"An examination of the effect of castor oil packs on constipation in the elderly","authors":"Arslan GG, Eşer I","year":2011,"journal":"Complement Ther Clin Pract","pmid":"21168117","url":"https://pubmed.ncbi.nlm.nih.gov/21168117/"},{"id":"4","title":"A Randomized Trial Comparing Potato Poultice Compress Versus Traditional Medicated Compress for Forearm Swelling After Trans-Radial Percutaneous Coronary Intervention","authors":"Zhang B, Tang C, Zou L, et al.","year":2026,"journal":"Catheter Cardiovasc Interv","pmid":"42446497","url":"https://pubmed.ncbi.nlm.nih.gov/42446497/"},{"id":"5","title":"Use of Alternative Medicine for Cancer and Its Impact on Survival","authors":"Johnson SB, Park HS, Gross CP, et al.","year":2018,"journal":"J Natl Cancer Inst","pmid":"28922780","url":"https://pubmed.ncbi.nlm.nih.gov/28922780/"},{"id":"6","title":"Mrs Barbara O’Neill – Breaches of Code of Conduct – Permanent Prohibition Order","authors":"NSW Health Care Complaints Commission","year":2019,"journal":"NSW HCCC media release, 24 Sep 2019","url":"https://www.hccc.nsw.gov.au/decisions-orders/media-releases/2019/mrs-barbara-o-neill-breaches-of-code-of-conduct-permanent-prohibition-order"},{"id":"7","title":"Honey and other environmental risk factors for infant botulism","authors":"Arnon SS, Midura TF, Damus K, et al.","year":1979,"journal":"J Pediatr","pmid":"368301","url":"https://pubmed.ncbi.nlm.nih.gov/368301/"},{"id":"8","title":"Nonpasteurized dairy products, disease outbreaks, and state laws-United States, 1993-2006","authors":"Langer AJ, Ayers T, Grass J, et al.","year":2012,"journal":"Emerg Infect Dis","pmid":"22377202","url":"https://pubmed.ncbi.nlm.nih.gov/22377202/"},{"id":"9","title":"Prevention of Group B Streptococcal Early-Onset Disease in Newborns: ACOG Committee Opinion, Number 797","authors":"American College of Obstetricians and Gynecologists","year":2020,"journal":"Obstet Gynecol","pmid":"31977795","url":"https://pubmed.ncbi.nlm.nih.gov/31977795/"},{"id":"10","title":"Effects of charcoal on the absorption and elimination of the antiepileptic drugs lamotrigine and oxcarbazepine","authors":"Keränen T, Sorri A, Moilanen E, et al.","year":2010,"journal":"Arzneimittelforschung","pmid":"20712131","url":"https://pubmed.ncbi.nlm.nih.gov/20712131/"},{"id":"11","title":"Ginger on Human Health: A Comprehensive Systematic Review of 109 Randomized Controlled Trials","authors":"Anh NH, Kim SJ, Long NP, et al.","year":2020,"journal":"Nutrients","pmid":"31935866","url":"https://pubmed.ncbi.nlm.nih.gov/31935866/"},{"id":"12","title":"Effects of Aloe vera on Burn Injuries: A Systematic Review and Meta-Analysis of Randomized Controlled Trials","authors":"Huang YN, Chen KC, Wang JH, et al.","year":2024,"journal":"J Burn Care Res","pmid":"38605441","url":"https://pubmed.ncbi.nlm.nih.gov/38605441/"},{"id":"13","title":"Ms Barbara O'Neill - Permanent Prohibition Order","authors":"NSW Health Care Complaints Commission","year":2021,"journal":"HCCC prohibition orders register (checked 21 Oct 2026)","url":"https://www.hccc.nsw.gov.au/decisions-orders/prohibition-orders/ms-barbara-oneill-permanent-prohibition-order"},{"id":"14","title":"Vaccines are not associated with autism: an evidence-based meta-analysis of case-control and cohort studies","authors":"Taylor LE, Swerdfeger AL, Eslick GD","year":2014,"journal":"Vaccine","pmid":"24814559","url":"https://pubmed.ncbi.nlm.nih.gov/24814559/"}],"wordCount":1627,"source":{"path":"src/content/topics/barbara-oneill-remedies/what-the-evidence-says.md"},"citeAs":"“Do Barbara O'Neill's natural remedies actually work?.” What's Healthy and Why. https://whatshealthyandwhy.com/barbara-oneill-remedies/what-the-evidence-says","notice":"General information backed by peer-reviewed research, not medical advice."}
