Natural Home Remedies for Food Poisoning

Introduction

Food poisoning, also called foodborne illness, occurs when we consume food that has been contaminated by microbes. These microorganisms can contaminate the food during any part of their processing journey till it reaches us and causes illness. Food poisoning is not necessarily caused by outside food, it can also occur when food is incorrectly handled or cooked at home. The symptoms of food poisoning can begin within a few hours of eating contaminated food. It may resolve without any treatment as well in mild cases, which is often the case, but sometimes in severe cases, a person might require hospital admission too⁴.

What Causes Food Poisoning?

Most often, food poisoning is seen in a large group of people who have all consumed the same contaminated food. It can also occur in individuals. Food poisoning is mainly the result of contamination of food, which can occur due to : 

• Improper handling of food, especially poultry and meat, through which microorganisms to enter our bodies if they are not killed thoroughly while cooking¹. 
• Consumption of eggs or meat that has been undercooked¹. 
• Contaminated water can also be the cause of it¹. 
• Unhygienic preparation of food by the use of unclean hands, utensils, cutting boards, etc¹. 
• Products that are kept out of the refrigerator for too long, especially foods with a tendency to get spoiled, like dairy products, food containing mayonnaise, etc¹. 
• Raw foods like fish or oysters, or raw vegetables that have not been washed well¹. 
• Untreated water can contain contaminants like bacteria, viruses, and parasites¹. 

Symptoms of Food Poisoning

Some of the most commonly experienced symptoms by people suffering from food poisoning are^{2, 5}: 

• Vomiting 
• Cramps in the stomach 
• Nausea
• Stomach upset 
• Diarrhoea 
• Fever 

Home Remedies for Food Poisoning

The symptoms of food poisoning can range from mild to very serious, depending on the type of microorganisms we get infected by and each body’s individual defense system². A few home remedies for food poisoning are as follows: 

1. Oral Rehydration Solution

As vomiting is one of the common symptoms experienced, rehydration becomes very important². ORS is the most scientifically supported home measure for food poisoning. It is recommended by health authorities worldwide to replace fluids and salts lost through vomiting and diarrhoea, and is considered a first-line approach for managing mild dehydration at home⁶.

Oral rehydration solution (ORS) can also be prepared at home by adding sugar and salt to a bottle of clean drinking water as per WHO guidelines. This homemade electrolyte-rich solution should be sipped every few minutes and should be used up within a day. Adding a pinch of cinnamon to coconut water and consuming it is also helpful for vomiting.

2. Lemon Juice

Lemon juice can be consumed by people when they experience food poisoning. It can be consumed by taking one glass of drinking water and squeezing half a lemon into it. It is a refreshing liquid and seems to make one feel better after consuming it. 

Although, lemon juice is refreshing and may help some people feel better, but there is little direct scientific evidence that it treats food poisoning. Its benefit is largely comfort-based⁷.

3. Apple Cider Vinegar

Apple cider vinegar is another popular home remedy being used for food poisoning. Add a few spoons of apple cider vinegar to a glass of water and consume two to three times a day to reap its benefits.  

Despite its popularity, there is insufficient scientific evidence to show that apple cider vinegar treats food poisoning. Claims about its benefits remain largely unverified.

4. Natural Oil

This is one of the more uncommon remedies used, but it is quite effective. Oregano oil or thyme oil, one of these two oils can be used. These oils seem to provide relief from the discomfort caused by food poisoning. To use it, we must add a few drops of the oil to water and consume it one to two times a day. How or why this works is not very clear.  

5. Bananas

Bananas are commonly consumed during recovery from diarrhoea because they are easy to digest and contain potassium, an electrolyte that can be lost during diarrhoea. Therefore, they are often included as part of supportive dietary measures during food poisoning. Some people consume a banana by mixing it with curd, for better effects, but it can be consumed directly as well. It may help support nutritional intake during recovery  

Bananas are easy to digest and provide potassium, an electrolyte that can be lost during diarrhoea. They are often part of bland diets recommended during recovery, so there is reasonable support for their supportive role⁸.

6. Ginger

Ginger (adrak) has been used in ayurveda for centuries to relieve vomiting, loss of appetite, and diarrhoea. A basin is made using amlaki and black gram around the navel. To this, the juice of fresh ginger is added once daily and retained for some time, to treat diarrhoea. As a cure for vomiting, ginger juice must be mixed with lemon juice and consumed fresh³. We can mix ginger (juice) in warm water and add honey to it as well. These home remedies are not just safe and natural, but also very tasty.   

Ginger has some research suggesting it may help ease nausea and vomiting. While it is not a cure for food poisoning, it may offer symptomatic comfort, making it a reasonable supportive remedy⁹.

7. Garlic

Swallowing fresh cloves of garlic with water is said to have beneficial effects on our bodies, as garlic acts like a cleansing agent. If consumed in a juice form, garlic is said to be even more effective, that is, if the pungent odour can be tolerated by you! It is said to be effective in the case of food poisoning.   

Garlic has known antimicrobial properties in laboratory studies, but there is limited evidence that eating it treats food poisoning in people. It should be viewed as a traditional remedy rather than a proven treatment¹⁰.

8. Cumin or Jeera

To use jeera as a remedy for food poisoning, we can take a little bit of jeera in water and boil it. After it boils, we can add a little coriander juice and salt to taste. This liquid preparation can be consumed a few times a day safely.    

9. Arishtaka

It is also known as Risht (in Hindi) or Indian soapnut, and it is used in ayurveda as a remedy for food poisoning. To use it, we need to soak a few of these aristhtaka seeds in a bottle of water and consume the water. This is said to reduce the poisoning³. 

10. Other Remedies

The following remedies are also recommended for use for diarrhoea in Ayurveda: 

• The fruit or rind of a pomegranate mixed with honey is to be used two to three times a day. 
• Buttermilk mixed with a spoonful of either fried cumin powder, fruit of long pepper or dried ginger powder should be divided into equal parts and given at regular intervals. 
• It is also known that the fruit rind of bael (Aegele marmalos) is useful for stomach-related problems. 

Why ORS Should Be Your First Priority?

When it comes to food poisoning, the biggest immediate risk is not the infection itself but dehydration. Vomiting and diarrhoea cause the body to lose large amounts of water and essential salts (electrolytes), which can leave you feeling weak, dizzy, and unwell¹¹.

This is why oral rehydration solution (ORS) is considered the first-line home measure for mild food poisoning involving vomiting or diarrhoea.

How ORS Helps:

ORS is more than just water. It contains a carefully balanced mix of salts and sugar that:

• Replaces the fluids lost through vomiting and loose stools.
• Restores essential electrolytes such as sodium and potassium.
• Helps the body absorb water more effectively than plain water alone.

Sipping ORS slowly and frequently throughout the day can help maintain hydration while your body recovers.

While other remedies in this article may provide comfort or ease certain symptoms, they should not replace ORS and adequate hydration. Keeping well-hydrated is one of the most important steps you can take at home while recovering from food poisoning.

When Home Remedies Are Not Enough?

Most cases of food poisoning are mild and improve on their own with rest and hydration. However, certain warning signs indicate that home care is not enough and prompt medical attention is needed.

Seek medical help if you notice any of the following:

• Severe dehydration, with signs such as very little or no urination, extreme thirst, a dry mouth, sunken eyes, confusion, or dizziness.
• Persistent vomiting lasting more than 24 hours, or being unable to keep any fluids down.
• Blood in the stool.
• High fever.
• Severe abdominal pain.
• Diarrhoea lasting more than 3 days.

If any of these occur, do not rely on home remedies alone; consult a doctor or healthcare provider without delay.

High-Risk Groups Who Need Extra Caution

Some people are more vulnerable to complications from food poisoning and should seek medical advice early, even with milder symptoms. These groups include¹²:

• Infants and young children, who can become dehydrated very quickly.
• Older adults, who may have a weaker ability to recover.
• Pregnant women, as certain infections can affect both mother and baby.
• People with weakened immune systems, such as those with chronic illnesses or on certain medications.

For these individuals, it is always safer to consult a healthcare professional promptly rather than waiting to see if symptoms improve.

Can Over-the-Counter Medicines Help?

In some cases, certain over-the-counter (OTC) medicines may help ease the symptoms of food poisoning in adults. For example, OTC anti-nausea or anti-emetic medicines are sometimes used to reduce nausea and vomiting, which may make it easier to keep fluids down.

While some adults may find these helpful, there are important safety points to keep in mind:

• OTC medicines treat symptoms only and do not cure the underlying infection.
• They are not suitable for everyone, and should generally be avoided in children unless advised by a doctor.
• If your symptoms are severe, or if you notice warning signs such as blood in the stool or a high fever, you should see a doctor rather than self-treating.
• Always read the label and follow the guidance provided, and check with a pharmacist or doctor if you are unsure.

Note: This section refers to general OTC options only. It does not cover prescription medicines, and you should always consult a doctor or pharmacist before taking any medication, especially if you have existing health conditions, are pregnant, or are caring for a child.

Helpful Products for Recovery

Alongside rest and a bland diet, a few products may support recovery from mild food poisoning. These are general options and not essential for everyone.

• ORS Products / Electrolyte Solutions: Ready-made ORS sachets and electrolyte solutions are widely available and offer a convenient, balanced way to stay hydrated. They are formulated to replace the fluids and salts lost through vomiting and diarrhoea, which is why they are often the preferred and are commonly recommended for replacing fluids and electrolytes lost through vomiting and diarrhoea.
• Probiotic Supplements: Probiotics are products that contain beneficial bacteria, which may help support gut health. Some people use them during or after a bout of food poisoning to support digestive function during recovery, although their role can vary from person to person¹³.

Note: These products may play a supportive role, but they are not a substitute for adequate hydration or medical care when it is needed. If you are unsure whether a product is suitable for you, it is best to check with a pharmacist or doctor before use.
