6 Shocking Health Effects of Nutmeg: Neurological, Heart & Digestive Risks You Must Know
Is Nutmeg Safe? The Truth About This Popular Spice in Asian Kitchens
Nutmeg (known as buah pala in Malay/Indonesian, jathikai in Tamil, jaiphal in Hindi, and *ลูกจันทน์เทศ in Thai) is one of the most loved warm spices across Asia Pacific kitchens. From creamy Indonesian bubur ketan hitam and Singaporean kueh to Indian garam masala blends and Filipino arroz caldo, a tiny grating of fresh nutmeg or a pinch of powder adds irresistible aroma and depth.
When used in normal cooking amounts, nutmeg is completely safe and even beneficial. It contains antioxidants, supports digestion, and has mild anti-inflammatory properties that traditional Ayurvedic and Jamu practices have celebrated for centuries.
Consumption of nutmeg becomes potentially risky when someone consumes it in abnormally large quantities. At high doses, a compound called myristicin acts as a natural deliriant and mild hallucinogen.
However the adverse reactions are extremely uncommon in everyday cooking because you would need to eat several tablespoons of pure nutmeg powder in one sitting to reach this toxic state.
Why Nutmeg Can Become Dangerous in High Doses
Timeline of Nutmeg Overdose Symptoms
- 30 minutes – 2 hours: Dry mouth, flushed skin, rapid heartbeat
- 2 – 6 hours: Intense nausea, vomiting, dizziness, feeling of “heaviness” in limbs
- 3 – 8 hours: Visual and auditory hallucinations, confusion, extreme anxiety, inability to distinguish reality (true delirium, not fun psychedelia)
- 8 – 48 hours: Lingering grogginess, body aches, dehydration, occasional palpitations
- Full recovery usually takes 1–3 days; hospital care is needed in severe cases

1. Neurological (Brain & Nervous System) Side Effects
Consuming too much nutmeg can have serious effects on the nervous system, with some reactions being potentially dangerous. The most common neurological symptoms include:
- Hallucinations – both visual and auditory distortions
- Delirium and confusion – difficulty thinking clearly or making decisions
- Disorientation and trance-like states – feeling detached from reality
- Severe agitation or anxiety – restlessness, panic, or emotional instability
- Drowsiness and extreme fatigue – overwhelming sleepiness or lethargy
- Dizziness and blurred vision – lightheadedness or impaired sight
- Slurred speech – difficulty articulating words clearly
- Headaches and memory issues – including temporary amnesia
In more serious cases, nutmeg overdose can cause:
- Tremors – involuntary shaking or muscle spasms
- Seizures – rare, but documented in extreme cases
- Acute psychosis – particularly with high or repeated doses
Why This Happens
These effects occur because compounds like myristicin and elemicin interfere with chemical signaling in the brain, mimicking the action of certain synthetic hallucinogens. The result is a long, unpleasant, and sometimes frightening experience that doctors call “nutmeg intoxication.”
2. Cardiovascular (Heart & Blood Pressure) Effects
Nutmeg overdose can also put significant stress on the cardiovascular system. Reported effects include:
- Rapid heartbeat (tachycardia) – an unusually fast pulse
- Irregular heartbeat (palpitations) – sensations of fluttering or skipped beats
- Low blood pressure (hypotension) – which can cause dizziness or fainting
- Occasionally high blood pressure (hypertension) – particularly in sensitive individuals
- Skin flushing and warmth – a sudden reddening of the face or body
- Chest discomfort – ranging from mild pressure to pain
For individuals with pre-existing heart conditions, these effects can be particularly concerning and may require immediate medical attention. Even in healthy adults, high doses of nutmeg can temporarily strain the heart and circulation.
3. Gastrointestinal (Digestive System) Effects
Nutmeg toxicity can also affect the digestive system, leading to uncomfortable and sometimes severe symptoms:
- Severe nausea – a persistent feeling of sickness
- Repeated vomiting – which can contribute to dehydration
- Abdominal pain and cramping – sharp or persistent stomach discomfort
- Diarrhea – loose or watery stools
- Dry mouth and reduced saliva – causing discomfort and difficulty swallowing
- Ileus – a temporary stoppage of bowel movements in severe cases
Severe vomiting and dehydration can intensify toxicity, making symptoms more pronounced and slowing recovery. Maintaining hydration and seeking medical attention if symptoms are severe is essential.
4. Sensory & Physical Disturbances
- Numbness or tingling in the arms and legs
- Burning or prickling sensations on the skin
- Eye irritation and dilated pupils (mydriasis)
- Increased sensitivity to light
- Fever and excessive sweating in some cases
- Grogginess and difficulty concentrating
- Body aches and muscle soreness
- Headaches
- Mental fog and lingering fatigue
5. Organ Stress and Long-Term Risks (High or Repeated Doses)
With repeated abuse or extremely high doses, nutmeg can have serious long-term effects on multiple organs and the nervous system:
- Liver stress or damage – often indicated by elevated liver enzymes
- Kidney strain – reduced efficiency in filtering toxins
- Cellular degeneration in brain tissue – observed in animal studies, potentially affecting cognitive and neurological function
- Impairment in auditory and neurological processing – subtle changes in hearing or brain signaling
- Psychosis-like episodes – rare but reported with repeated misuse
- Psychological dependence – uncommon, but some cases of habitual misuse have been documented
While fatalities are extremely rare, they have occurred with very high doses, especially when combined with other substances. These risks highlight that nutmeg, though natural, can become dangerous when consumed far beyond normal culinary amounts.
6. Pregnancy, Children, and High-Risk Groups
Certain populations are particularly vulnerable to nutmeg toxicity:
- Children – their smaller body size makes them more susceptible to toxic effects
- Pregnant women – high doses can pose serious risks to both mother and fetus
- Individuals with heart, liver, kidney, or neurological conditions – pre-existing health issues can amplify toxic effects
- People taking psychiatric or cardiovascular medications – interactions with drugs such as MAOIs, SSRIs, or blood pressure medications may increase danger
During pregnancy, large doses of nutmeg are considered unsafe and may lead to:
- Miscarriage – uterine stimulation and toxicity can increase risk
- Fetal toxicity – compounds like myristicin can cross the placenta
- Developmental complications – potential impacts on growth or neurological development
For these groups, it is essential to limit nutmeg to typical culinary amounts or avoid it entirely, ensuring both safety and peace of mind.

Beware of online “nutmeg challenge”
Nutmeg is one of the safest spices in your kitchen, as long as you use it the way it’s meant to be used, as a spice. The moment problems begin is when people stop treating nutmeg like a flavoring and start treating it like a supplement or a so-called “natural remedy.” That is where real health concerns start to appear.
Early signs of toxicity include nausea, dizziness, dry mouth, and flushed skin, while more severe effects may involve hallucinations, confusion, rapid heartbeat, or abdominal pain. For children, pregnant women, and individuals with heart, liver, kidney, or neurological conditions, even moderate amounts can be risky.
If you or someone in your household experiences these after accidentally adding way too much nutmeg (or worse, after trying an online “nutmeg challenge”), stop eating, drink water, and monitor closely. Seek medical help immediately.
Simple, Smart Rules Every Household Can Follow
- Grate only what you need. Freshly grated nutmeg tastes better, and using small amounts naturally prevents overdoing it.
- Never use nutmeg as a home remedy for sleep, anxiety, or stress. What seems “natural” can still be harmful in large doses.
- Store whole and ground nutmeg in labeled, airtight containers and always keep them out of children’s reach.
- When a recipe says “a pinch,” believe it. Nutmeg is powerful, and just a tiny amount delivers plenty of flavor.
- Keep nutmeg away from heat and direct sunlight. Proper storage preserves its aroma and strength while also reducing the risk of accidental overuse.
