This Odd Smell Recovery Trick Has Doctors Raising Eyebrows
Doctors Question the "Odd Trick" for Smell and Taste Recovery
The "odd trick" is the viral burnt orange remedy: people char an orange, mix it with sugar, and eat it to try to restore smell and taste after COVID-19, but doctors say there is no solid evidence that this DIY hack works, and it may irritate the mouth or throat instead.
What the trick claims to do
The viral idea behind the charred citrus method is that strong heat, bitter compounds, and sweet flavor together might "wake up" the senses. In practice, supporters say the burnt aroma and intense taste act like a reset button for smell and taste loss, especially after viral illness. That claim sounds plausible on social media, but it is not the same as clinical proof.
Medical experts have repeatedly pointed out that smell loss, or anosmia, and taste changes after COVID-19 usually improve gradually over time, often with structured rehabilitation rather than a shortcut. The most discussed evidence-backed approach is olfactory training, not a one-food fix. Harvard Health and UCHealth both describe repeated sniffing of specific scents as a more credible method than burnt-fruit trends.
Why doctors are skeptical
Doctors question the social media hack for three main reasons: it lacks controlled studies, it does not target the underlying nerve recovery process, and it may encourage people to delay proper evaluation. A TikTok trend can spread quickly, but speed of sharing is not evidence of effectiveness. In contrast, medical guidance usually relies on repeated scent exposure, symptom tracking, and follow-up when recovery stalls.
The strongest concern is that smell and taste problems are not always caused by the same thing. Viral infections, sinus disease, medication side effects, dental problems, smoking, reflux, and neurologic conditions can all affect flavor perception. A one-size-fits-all trick can therefore miss the real cause, which is why clinicians recommend assessing persistent symptoms rather than guessing at home.
What actually helps
The best-supported home approach is smell training, also called olfactory retraining. This usually means sniffing a small set of distinctive scents, such as lemon, rose, eucalyptus, clove, peppermint, or rosemary, for about 15 to 30 seconds each, twice daily, for weeks or months. Multiple medical sources describe this as the most practical first-line strategy for persistent smell loss after viral illness.
- Use strong, familiar scents such as citrus, spice, floral, or mint.
- Sniff each scent gently and repeatedly instead of taking one deep breath.
- Continue daily for at least several weeks.
- Track changes so you can notice gradual improvement.
- See an ENT specialist if symptoms do not improve or worsen.
Food-based strategies can also support recovery, especially for taste perception. Doctors often suggest using herbs, spices, ginger, lemon, vinegar, and other bold flavors to make meals more interesting while the senses recover. Good oral hygiene, smoking cessation, and limiting alcohol can also reduce confounding factors that make taste seem worse.
What the evidence suggests
Current medical reporting suggests many people improve with time, and a large majority recover partially or fully within a year after COVID-related smell and taste loss. Mayo Clinic reporting has said roughly 95 percent of affected patients can expect improvement in less than a year, though the timeline varies widely. That does not mean everyone recovers quickly, but it does mean patience and structured therapy matter more than viral hacks.
| Approach | What it is | Evidence level | Main caution |
|---|---|---|---|
| Burnt orange trick | Char an orange and eat it with sugar | Weak or none | May irritate mouth or delay proper care |
| Smell training | Repeatedly sniff distinct scents | Moderate support | Requires consistency over weeks |
| Flavor boosting | Use herbs, spice, ginger, citrus, vinegar | Supportive care | Not a cure, but may improve eating |
| ENT evaluation | Medical workup for persistent loss | Standard care | Needed if symptoms persist or are unusual |
- Confirm how long the smell or taste loss has lasted.
- Start daily smell training with several distinct scents.
- Use stronger flavors and better oral hygiene to make meals more tolerable.
- Avoid smoking and reduce alcohol if possible.
- Seek medical evaluation if recovery is incomplete after several weeks or if symptoms are severe.
How long recovery takes
Recovery from smell and taste loss is often slow, which is one reason people become attracted to dramatic home fixes. The first weeks after losing smell may be the best window for improvement, according to ENT specialists quoted in medical reporting, but gains can still continue later. A person may notice subtle changes first, such as faintly detecting coffee, garlic, or perfume before full recovery returns.
Doctors also note that smell and taste are related but not identical. Much of what people call "taste" is actually smell, especially the flavor complexity of food. That is why smell training can improve the experience of eating even when the tongue itself is not the main problem.
When to get checked
A persistent loss of smell or taste deserves attention if it lasts more than a few weeks, appears after head injury, comes with nasal obstruction, or is paired with neurologic symptoms. If the problem is accompanied by weight loss, fever, facial pain, or one-sided symptoms, it is especially important to rule out another cause. The burnt-orange trend cannot distinguish between temporary post-viral loss and a more serious medical issue.
"The simplest approach is to select about four or five fragrant items from your home that you remember," one ENT expert advised in reporting on smell retraining, emphasizing daily repetition rather than a single novelty remedy.
What this means now
The bottom line for the odd trick question is simple: doctors do not endorse burnt oranges as a reliable fix, but they do support smell training, symptom tracking, and medical evaluation when recovery lingers. People who want the best odds should skip the viral shortcut and use the evidence-based routine that ENT specialists actually recommend.
Expert answers to This Odd Smell Recovery Trick Has Doctors Raising Eyebrows queries
Is the burnt orange trick dangerous?
It can be, mainly because the fruit may be very hot and the charred surface can irritate the mouth or throat, while also distracting people from better-supported treatment. It is not a proven therapy for smell or taste recovery.
Does smell training really work?
Smell training is the most consistently recommended at-home option, and multiple medical sources say it can help people recover smell function over time. It is not instant, but it is much more credible than a single viral food hack.
How often should scent training be done?
Most guidance suggests once or twice a day, with each scent sampled for about 15 to 30 seconds. The key is repetition over weeks, not intensity in one session.
Can taste come back if smell does not?
Sometimes partially, but many people who think they have lost taste are actually experiencing smell loss that changes flavor perception. That is why treatment often focuses on olfactory recovery first.
