Oil Pulling for Health & Longevity

Evidence Review created on 07/25/2026 using AI4L / Opus 4.8

Also known as: Oil Swishing, Kavala, Gandusha, Kavala Graha

Motivation

Oil pulling is the practice of swishing a spoonful of edible oil — most often coconut or sesame — around the mouth for several minutes and then spitting it out. It is used as an add-on to normal oral care in the hope of cleaner teeth, healthier gums, and fresher breath. The idea is simple: the oil coats the teeth and gums, mixes with saliva, and is thought to lift away some of the bacterial film in the mouth.

The practice comes from traditional Indian medicine, where it was used for centuries and later promoted far more widely once inexpensive coconut oil made it easy for anyone to try at home. Interest has grown as researchers increasingly link the health of the mouth to the health of the whole body, from the heart to blood sugar control, making a cheap and gentle mouth-care habit worth a closer look.

This review examines what the evidence does and does not show about oil pulling: its possible effects on gum inflammation, mouth bacteria, plaque, and breath, the practical ways it is done, its safety, and the open questions that remain. It weighs the strength of the evidence, not the popularity of the claims.

Systematic Reviews

This section summarizes the systematic reviews and meta-analyses of oil pulling identified on PubMed, prioritized by recency, study size, and direct relevance.

The largest synthesis to date, pooling 25 trials and 1184 participants. Oil pulling improved gum inflammation scores versus non-chlorhexidine rinses, while chlorhexidine (a prescription antibacterial mouth rinse) remained better at reducing plaque; the authors rated overall certainty as very low.

A meta-analysis of nine randomized controlled trials (studies that randomly assign participants to treatment or control) that found a significant reduction in salivary bacterial counts with oil pulling but no significant difference in plaque or gum inflammation scores versus controls.

A systematic review focused specifically on coconut oil, including four trials of 182 participants; it reported reductions in salivary bacteria and plaque but flagged high risk of bias and insufficient data for firm conclusions.

An Oxford evidence-based-medicine review of five trials that found suggestive but limited short-term benefits, emphasizing that oil pulling is low-cost and potentially useful while calling for more rigorous trials.

A recent review of traditional oral-hygiene methods; for oil pulling with sesame or coconut oil it reports moderate reductions in bacterial load and improved gum health, with results varying against chlorhexidine and methodological limits urging caution.

Mechanism of Action

Oil pulling is a topical, non-systemic practice: the oil acts inside the mouth and is spat out rather than absorbed, so its effects are local to the teeth, gums, and oral bacteria. Several mechanisms have been proposed.

  • Mechanical and emulsifying action: Swishing the oil for several minutes coats the teeth and gums and, as the oil mixes with saliva, it emulsifies (breaks into tiny droplets). This is thought to physically trap and lift bacteria and the sticky biofilm (dental plaque) off tooth surfaces, which are then removed when the oil is spat out.

  • Antimicrobial fatty acids: Coconut oil is rich in lauric acid, a fat that can be converted to monolaurin (a compound with germ-killing properties). These are proposed to disrupt the membranes of cavity-causing bacteria such as Streptococcus mutans (a leading cause of tooth decay), reducing their numbers in saliva.

  • Antioxidant components: Sesame oil contains sesamol and sesamin (natural antioxidants), which have been suggested to reduce inflammation and the oxidative damage associated with gum disease, offering a possible route to improved gum health.

Competing views exist. Skeptics argue that any measured benefit is largely explained by the simple mechanical act of swishing any liquid and the extra time spent on oral care, rather than by a unique property of the oil, and note that the popular claim that oil pulling “pulls toxins” out of the bloodstream has no supporting evidence. Supporters counter that the specific reductions seen in S. mutans counts and gum inflammation with oil, beyond water rinsing, point to a genuine chemical contribution. Current evidence cannot fully separate these explanations.

As oil pulling is not a pharmacological compound taken into the body, systemic pharmacological properties such as half-life, tissue distribution, and enzyme metabolism do not apply.

Historical Context & Evolution

  • Traditional origin: Oil pulling originates in traditional Indian (Ayurvedic) medicine, where it is described under the terms kavala (a full mouthful swished vigorously) and gandusha (holding oil in the mouth). It was practiced as a daily oral-hygiene ritual, typically with sesame or sunflower oil, and was traditionally credited with benefits ranging from strong teeth and gums to relief of a wide array of ailments.

  • Original intended use: Its core traditional purpose was oral cleanliness — maintaining healthy teeth, gums, and breath — embedded within a broader wellness framework that also ascribed whole-body benefits to the practice.

  • Modern revival: The practice re-entered wider awareness in the 1990s after a Ukrainian-Russian physician, popularly cited as Dr. F. Karach, promoted it with expansive health claims. These claims spread through early internet communities and, in the 2000s and 2010s, oil pulling became a mainstream wellness trend, accelerated by the popularity of inexpensive, palatable coconut oil.

  • Why it drew health-optimization interest: Growing scientific attention to the oral microbiome (the community of microbes in the mouth) and to links between oral health and conditions such as heart disease and diabetes made a low-cost, low-risk mouth-care habit attractive to people seeking to optimize long-term health.

  • Evolution of scientific opinion: Early enthusiasm rested largely on tradition and small studies. As controlled trials accumulated, reviews converged on a cautious middle position — plausible short-term benefits for gum inflammation and bacterial load, but low-certainty evidence and no support for systemic “detox” claims. This remains an active and unsettled area rather than a closed question; newer and larger trials continue to refine the picture in both directions.

Expected Benefits

The benefits below are grouped by the strength of the supporting evidence. A dedicated search of clinical trials, meta-analyses, and expert sources was performed to ensure the profile is complete. For a health- and longevity-oriented reader, the realistic value of oil pulling lies in oral hygiene as an add-on habit, not in systemic disease treatment.

Medium 🟩 🟩

Reduced Gingival Inflammation

Multiple randomized controlled trials and the largest meta-analysis to date report that oil pulling improves standardized gum-inflammation scores, and that the effect can exceed non-antibacterial rinses. The proposed basis is reduced bacterial load and the antioxidant/anti-inflammatory components of the oils. Evidence certainty is rated low by reviewers because trials are small, short, and varied, so the effect is best viewed as a probable short-term benefit for gum health used alongside standard care.

Magnitude: In pooled analysis, oil pulling improved modified gum-inflammation scores versus non-chlorhexidine rinses with a standardized mean difference (a way to combine results measured on different scales) of about −1.14 (95% confidence interval −1.31 to −0.97).

Reduced Oral Bacterial Load

Several trials and a meta-analysis show that oil pulling lowers the count of bacteria in saliva, including cavity-associated Streptococcus mutans. The likely mechanism combines mechanical removal of biofilm with the antimicrobial fatty acids in coconut oil. Because reductions in bacterial counts do not always translate into fewer cavities or measurable gum improvement in the same trials, this is a consistent but intermediate-strength finding.

Magnitude: A meta-analysis found a significant reduction in salivary bacterial colony counts favoring oil pulling (mean difference about 17.55, 95% confidence interval 2.56 to 32.55, on the reported colony scale).

Low 🟩

Reduced Dental Plaque ⚠️ Conflicted

Evidence on plaque is directly conflicting. Some individual trials and a coconut-oil-focused review report meaningful plaque reductions versus baseline, whereas the largest meta-analysis found chlorhexidine clearly superior to oil pulling for plaque control, and another meta-analysis found no significant plaque difference versus controls. The discrepancy likely reflects differences in oils used, swishing duration, trial length, and how plaque was scored. Oil pulling should therefore be seen as, at best, a modest adjunct for plaque, not a replacement for brushing or a prescription rinse.

Magnitude: Chlorhexidine outperformed oil pulling for plaque in pooled analysis (standardized mean difference about 0.33 favoring chlorhexidine); individual trials report plaque-index reductions of roughly 18–30% from baseline with oil pulling.

Reduced Halitosis (Bad Breath)

Small trials suggest oil pulling can reduce the volatile sulfur compounds (the gases that cause bad breath) and improve breath odor, in some cases comparably to a chlorhexidine rinse. The proposed mechanism is a reduction in the odor-producing bacteria on the tongue and gums. Evidence is limited to small, short studies, so the effect is plausible but not well quantified.

Magnitude: Not quantified in available studies.

Speculative 🟨

Teeth Whitening & Stain Reduction

A frequent popular claim is that oil pulling whitens teeth. Direct evidence is minimal; any effect is more plausibly explained by removal of surface bacteria and debris than by true bleaching, and expert commentary suggests it does little more than rinsing. A dedicated whitening trial is currently underway, but as of now the basis is largely anecdotal.

Systemic & Longevity Benefits via the Oral-Systemic Link

Because poor oral health is associated with heart disease, diabetes, and inflammation, it is proposed that better mouth hygiene could contribute to long-term systemic health. This is mechanistic and indirect: no trial has shown that oil pulling changes any systemic or longevity outcome. The rationale is biologically reasonable but entirely speculative for this practice specifically.

Benefit-Modifying Factors

  • Baseline oral health: People starting with more gum inflammation or higher plaque and bacterial loads tend to show larger measurable improvements, whereas those with already-excellent oral hygiene have less room to benefit.

  • Baseline biomarker levels: Higher baseline salivary Streptococcus mutans counts and higher gum-bleeding scores predict a more noticeable response, since the practice acts by lowering these.

  • Oil type and technique: Coconut oil’s lauric acid may add an antimicrobial effect that plain swishing lacks, and longer, consistent daily swishing appears more effective than brief or irregular use — making adherence a key modifier.

  • Pre-existing conditions: Those with dry mouth (reduced saliva) may find emulsification less effective, while people with active gum disease may perceive more benefit as an adjunct to professional care.

  • Sex-based differences: No reliable sex-based differences in oil-pulling benefit have been established; trials have not been designed or powered to detect them.

  • Age-related considerations: Adults across the age range can use the practice; older adults with more gum recession or existing periodontal disease may notice adjunctive benefit, but should not substitute it for professional treatment.

Potential Risks & Side Effects

Oil pulling is widely regarded as low-risk, and a dedicated search of dental references and case-report literature was performed to ensure completeness. The risks below are grouped by evidence strength; the most consequential risk for a health-focused reader is behavioral rather than biological.

High 🟥 🟥 🟥

Displacement of Evidence-Based Oral Care

The best-documented harm is indirect: relying on oil pulling in place of brushing, flossing, fluoride, and professional dental care. Because oil pulling does not match fluoride or a chlorhexidine rinse for preventing cavities and controlling plaque, using it as a substitute can allow decay and gum disease to progress. Dental organizations consistently note it should only ever be an add-on. This risk is essentially certain when the practice replaces, rather than supplements, proven care.

Magnitude: Not quantified in available studies.

Low 🟥

Lipoid Pneumonia (Oil Aspiration)

Isolated case reports describe lung inflammation (lipoid pneumonia, caused by inhaling small amounts of oil) after oil pulling, typically when oil is accidentally drawn into the airway during vigorous or careless swishing. It is rare but potentially serious, and more likely in people with swallowing difficulty. The risk is minimized by gentle swishing and never inhaling or swallowing the oil.

Magnitude: Not quantified in available studies.

Gastrointestinal Upset

Swallowing the oil — deliberately or accidentally — can cause nausea, an upset stomach, or loose stools, and the spent oil holds bacteria and debris that are not meant to be ingested. Effects are mild and self-limiting and are avoided simply by spitting the oil out.

Magnitude: Not quantified in available studies.

Jaw Muscle Fatigue & Soreness

Swishing continuously for 15–20 minutes can tire the jaw muscles and cause temporary soreness, particularly for beginners or people with jaw-joint (temporomandibular) issues. It resolves with rest and shorter sessions.

Magnitude: Not quantified in available studies.

Speculative 🟨

Allergic or Sensitivity Reaction

People allergic to coconut or sesame could in principle react to the corresponding oil, with mouth irritation or, rarely, more significant allergy. This is based on general allergy mechanisms rather than oil-pulling-specific reports, and is avoided by choosing an oil one is not sensitive to.

Risk-Modifying Factors

  • Swallowing ability and airway control: People with impaired swallowing, a strong gag reflex, or neurological conditions affecting the airway have a higher aspiration risk and should be cautious or avoid the practice.

  • Pre-existing conditions: Active, untreated dental disease raises the stakes of substituting oil pulling for real care; jaw-joint disorders increase the chance of muscle soreness from prolonged swishing.

  • Known allergies: A coconut or sesame allergy converts a benign oil into a genuine hazard; the modifiable factor is simply oil choice.

  • Age-related considerations: Young children are prone to swallowing or aspirating the oil and are generally not suitable candidates; older adults at the upper end of the target range with swallowing changes should take extra care.

  • Baseline biomarkers and sex: No reliable baseline-biomarker or sex-based factors that modify oil-pulling risk have been established in the literature.

Key Interactions & Contraindications

  • Prescription drug interactions: None are known. Oil pulling is topical and spat out, so it does not meaningfully enter the bloodstream and has no established interactions with oral or systemic medications.

  • Over-the-counter medication interactions: None are known. It is compatible with common over-the-counter products such as pain relievers and antacids.

  • Supplement interactions: None are known. It does not interfere with the absorption of oral supplements, though as a courtesy it is done before, not during, taking anything by mouth.

  • Additive / complementary oral-care agents: Fluoride toothpaste and, where prescribed, a chlorhexidine rinse have additive value for cavity and plaque control; these should be continued, with oil pulling used as an extra step rather than a replacement. Separating oil pulling from a chlorhexidine rinse by some minutes avoids the oil coating reducing the rinse’s contact.

  • Other intervention interactions: It layers safely with brushing, flossing, tongue scraping, and professional cleanings, and is best positioned as the first step of a morning routine.

  • Populations who should avoid it: Young children (aspiration and swallowing risk), individuals with significant swallowing disorders or a very strong gag reflex, anyone with a known allergy to the chosen oil, and people who would use it to replace professional dental treatment for active disease.

  • Severity and consequences: Interactions are, in practical terms, absent; the meaningful contraindications above are best classified as “caution” to “avoid,” with the main consequence being aspiration risk in vulnerable groups or untreated disease progression if it displaces real care.

Risk Mitigation Strategies

  • Use as an add-on, never a replacement: Keep brushing twice daily with fluoride toothpaste, flossing, and routine dental visits; add oil pulling on top. This directly prevents the highest-consequence risk — decay and gum disease progressing because proven care was dropped.

  • Swish gently and never inhale or swallow: Move the oil slowly and keep the head level rather than tilted back, and spit it all out. This mitigates the rare but serious risk of oil aspiration and lipoid pneumonia, and avoids the stomach upset from swallowing.

  • Start short and build up: Begin with 1–5 minutes and increase toward 10–20 minutes only as tolerated. This prevents jaw-muscle fatigue and soreness, especially for beginners or those with jaw-joint issues.

  • Match the oil to individual tolerances: A coconut or sesame oil free of known allergens is used, switching oils if any mouth irritation appears. This mitigates allergic or sensitivity reactions.

  • Spit into the trash, not the sink: Disposing of the oil in a bin or paper towel avoids drain clogging; while a plumbing rather than health issue, it prevents a common practical failure that leads people to abandon the habit.

  • Supervise or avoid in vulnerable groups: Do not use with young children or people with swallowing difficulties. This prevents aspiration in those least able to control the oil safely.

Therapeutic Protocol

A standard, practitioner-described protocol for oil pulling is consistent across integrative dentists and traditional sources, with the main variation being session length.

  • Oil choice: Use about one tablespoon (10–15 mL) of an edible oil. Coconut oil is the most popular for its taste and lauric-acid content; sesame oil is the classical Ayurvedic choice; some use a smaller amount to reduce jaw fatigue.

  • Timing (best time of day): Perform it in the morning on an empty stomach, before eating, drinking, or brushing, when the overnight bacterial load is highest. Traditional practice and modern proponents such as integrative dentists both favor this timing.

  • Duration: Swish gently for 5–20 minutes. Traditional and research protocols often use 15–20 minutes, but experienced clinicians note that 1–5 minutes still provides meaningful benefit and improves adherence.

  • Technique: Move the oil slowly around the mouth and pull it between the teeth; do not tilt the head back, inhale, or swallow. Spit the oil into the trash, rinse the mouth with water, then brush as normal.

  • Frequency (single vs. split dosing): Once daily is the standard approach; it is used as a single morning session rather than split through the day. Some traditional protocols allow up to two to three times daily, but there is no evidence this adds benefit.

  • Competing approaches: The main alternatives are the conventional approach (brushing with fluoride, flossing, and a therapeutic rinse such as chlorhexidine when indicated) and the integrative approach (oil pulling plus tongue scraping and a low-sugar diet, with conventional care retained). Neither is framed here as the default; the conventional measures have stronger cavity- and plaque-prevention evidence, while oil pulling adds a gentle, low-cost gum-focused step.

  • Pharmacokinetics: As a topical practice that is spat out, oil pulling has no systemic half-life or absorption to optimize; “dosing” refers only to volume and swishing time.

  • Genetic, sex, age, biomarker, and condition factors: No pharmacogenetic variants govern oil pulling. No sex-based dosing differences are established. Older adults and those with gum disease may use it as an adjunct but should keep professional care central; people with dry mouth may need a little more oil or saliva-stimulating measures; children and those with swallowing difficulty should not use it. Higher baseline plaque, bacterial counts, or gum bleeding predict a more noticeable response.

Discontinuation & Cycling

  • Lifelong vs. short-term: Oil pulling can be used indefinitely as a daily habit or intermittently as desired; there is no requirement for lifelong continuation and no accumulating dependence.

  • Withdrawal effects: None are known. Because nothing is absorbed systemically, stopping produces no withdrawal symptoms; any oral-hygiene gains simply plateau or gradually reverse if overall care declines.

  • Tapering: No taper is needed. The practice can be stopped abruptly at any time without adverse effect.

  • Cycling: Cycling is not required to maintain efficacy; benefits depend on consistent use rather than on rotating on and off. There is no evidence that pausing periodically improves results.

Sourcing and Quality

  • Oil selection: Choose a food-grade edible oil intended for consumption. Virgin or extra-virgin, cold-pressed, unrefined coconut oil and unrefined sesame oil are the most commonly recommended for oil pulling.

  • What to look for: Prefer cold-pressed, unrefined, and ideally organic oils to minimize solvent residues; check for a fresh smell and taste and avoid rancid oil. Third-party quality testing or certification (for purity and absence of contaminants such as heavy metals or pesticide residues) adds confidence, since these oils are food products rather than regulated medicines.

  • Formulation: Plain single-ingredient oils are standard. Some products add flavoring or essential oils; these are optional and should be verified as safe for oral use, as they add potential irritants without proven added benefit.

  • Reputable options: Widely available culinary brands of organic virgin coconut oil and unrefined sesame oil are suitable; some companies also sell pre-portioned oil-pulling sachets for convenience, which trade higher cost for portion control.

Practical Considerations

  • Time to effect: Reductions in mouth bacteria can appear within days to two weeks in trials, while measurable improvements in gum inflammation typically emerge over two to six weeks of daily use; benefits fade if the habit stops.

  • Common pitfalls: The frequent mistakes are treating oil pulling as a replacement for brushing and flossing, swishing so long or vigorously that the jaw tires or oil is aspirated, swallowing the used oil, spitting it into the sink and clogging drains, and expecting whitening or “detox” effects that are not supported.

  • Regulatory status: Oil pulling is an unregulated wellness practice, not a medical treatment; the oils are sold as foods. Dental authorities such as the American Dental Association do not endorse it as a substitute for standard care, citing insufficient evidence.

  • Cost and accessibility: It is inexpensive and highly accessible — a jar of coconut or sesame oil costs little and lasts weeks — which is a major reason for its appeal; cost is not a barrier.

Interaction with Foundational Habits

  • Sleep: Direction — indirect/neutral. Oil pulling does not contain stimulants and does not directly affect sleep. Indirectly, better oral health is associated with reduced nighttime mouth-related irritation; practically, it fits naturally into a morning routine rather than a bedtime one.

  • Nutrition: Direction — indirect. Done fasted before breakfast, it does not add meaningful calories because the oil is spat out. It complements a low-sugar, low-refined-carbohydrate diet, which reduces the cavity-causing bacteria oil pulling also targets; choosing coconut versus sesame oil is a taste-and-tolerance choice rather than a nutritional one.

  • Exercise: Direction — none. There is no known interaction between oil pulling and exercise, and no timing considerations relative to workouts.

  • Stress management: Direction — indirect/neutral. It has no measured effect on stress hormones such as cortisol, but the several-minute swishing session can serve as a brief, quiet morning routine that some people fold into a mindfulness or grounding habit.

Monitoring Protocol & Defining Success

Because oil pulling is a topical oral-care practice, systemic blood work is not indicated; monitoring focuses on oral-health markers assessed at home and by a dental professional. Before starting, a simple baseline snapshot — a recent dental check-up plus noting current gum bleeding, breath, and any sensitivity — makes it possible to judge whether the practice adds value.

Ongoing monitoring is best aligned with routine dental care: a professional check-up and cleaning every 6–12 months, with self-assessment of gum bleeding and breath every few weeks during the first 1–2 months and periodically thereafter.

Biomarker Optimal Functional Range Why Measure It? Context/Notes
Gum bleeding (bleeding on probing) 0–10% of sites Tracks gum inflammation, the most likely benefit Assessed by a dentist or hygienist; conventional care often accepts <20%, so the lower target reflects an optimal, not just adequate, standard
Plaque index Near 0 (minimal visible plaque) Gauges biofilm control and technique Home disclosing tablets can make plaque visible; oil pulling is an adjunct to, not a substitute for, brushing here
Salivary Streptococcus mutans count Low (below roughly 10⁵ colony-forming units/mL) Reflects cavity-causing bacterial load, which oil pulling can lower Chairside kits exist but this is not a routine test; best paired with a dietary sugar review; morning sampling before eating is most consistent

Qualitative markers to track alongside the table:

  • Breath freshness: morning and daytime breath quality, self-assessed or noted by others.
  • Gum comfort and bleeding: whether gums bleed less when brushing or flossing.
  • Tooth-surface feel: a smoother, cleaner feel to the teeth after sessions.
  • Mouth comfort: absence of jaw soreness, irritation, or dryness with the routine.

Success is best defined as steady or improving professional gum and plaque scores and self-reported breath and gum comfort, achieved without displacing brushing, flossing, or dental visits. A lack of change after 6–8 weeks of consistent use is a reasonable signal that the practice is not adding value for that individual.

Emerging Research

Research on oil pulling is active but small-scale, and current work is framed around oral-health endpoints most relevant to a health-focused individual rather than population disease outcomes.

  • Whitening and stain reduction trial: A randomized study of an oil-pulling whitening mouthwash in healthy adults is recruiting, measuring tooth shade and stain indices — directly testing the popular whitening claim that currently lacks support (NCT07667088, ~120 participants).

  • Gum health and oral microbiome trial: A recruiting trial is evaluating oil pulling against gum-inflammation, bleeding, and plaque indices together with plaque-microbiome analysis, which could clarify whether measured bacterial shifts track with clinical gum improvement (NCT07706647, ~120 participants).

  • Coconut oil pulling versus fluoride in children: A planned trial comparing coconut oil pulling (with and without clove oil) to fluoride mouthwash on Streptococcus mutans counts will help define where oil pulling stands relative to a proven cavity-prevention agent (NCT06902532, ~105 participants).

  • Need for larger, higher-certainty trials: The dominant future direction is simply better evidence. The largest meta-analysis to date graded certainty as very low and called for rigorous, adequately powered, well-reported trials; such studies could strengthen or weaken the current gum-health and bacterial signals (Jong et al., 2024).

  • Oral-systemic connection: Whether improved oral hygiene meaningfully affects systemic health remains open. Reviews of the oral microbiome’s links to heart, metabolic, and brain health outline why the question matters, but no study yet connects oil pulling specifically to systemic outcomes — a gap that could shift the case in either direction (Rajasekaran et al., 2024).

Conclusion

Oil pulling is a simple, inexpensive practice of swishing edible oil — usually coconut or sesame — in the mouth and spitting it out, used as an add-on to everyday mouth care. The most consistent signals from research are a probable reduction in gum inflammation and in the bacteria found in saliva, with fresher breath a plausible secondary effect. Its impact on plaque is genuinely mixed, and prescription antibacterial rinses remain better at plaque control. Claims that it whitens teeth, pulls toxins from the body, or treats disease are not supported by good evidence.

The overall quality of the evidence is low: most studies are small, short, and varied, so even the more encouraging findings carry real uncertainty. The main downside is not the practice itself, which is very low-risk, but the temptation to let it stand in for brushing, flossing, fluoride, and dental visits — the measures with the strongest backing. Rare problems such as inhaling oil or jaw soreness are avoidable with gentle technique.

For someone focused on long-term health, oil pulling reads as a low-cost, low-risk extra that may modestly help the gums and mouth, layered on top of proven care rather than replacing it, with realistic rather than sweeping expectations and much still left to confirm.
