Natural Home Remedies for Dengue 

Introduction

Dengue is a well-known disease that is spread by a mosquito carrying the dengue virus. The dengue virus is common in tropical and subtropical places worldwide, including parts of Asia and the Pacific Islands, Africa, Eastern Mediterranean, and Central and South America. Although it is not transmitted from person to person, the virus can be transmitted from pregnant mothers to their children1.

Dengue can cause high fever and other symptoms, which may sometimes even become life-threatening. Knowing the signs and symptoms of dengue can help with early detection and quicker recovery. In this blog, we will discuss some basic facts and tell-tale signs of dengue, aiming to provide you with the knowledge on when prompt action is needed from your side.  

What Causes Dengue?

Dengue is caused by the Dengue virus. This virus enters the human blood through bite of Aedes mosquito, particularly Aedes aegypti and Aedes albopictus species. The mosquito carries the virus in its saliva. The virus starts to multiply after entering your blood. Finally, the virus along with the immune system’s response makes you feel sick1.   

Symptoms of Dengue

In most cases, one might not experience any symptoms of dengue fever. However, high fever is the most common symptom of dengue. Other possible symptoms of dengue include:  

One might start experiencing the symptoms only four to ten days after the mosquito bite, which may last for three to seven days. Although recovery may take longer in some individuals. 

If you notice these symptoms, reach out to your doctor immediately. Timely intervention can help you recover quickly.   

Home Remedies for Dengue

While medical treatment remains the cornerstone of management of dengue, some simple home remedies may help with easing your symptoms when used adjunctly. These include:  

1. Neem

Some lab studies have shown that neem leaf extract could stop the growth of the dengue virus in animals3. However, there is currently insufficient evidence from human studies to show that neem can treat or cure dengue. Therefore, neem leaves may be used for general wellness.

Boil some fresh neem leaves in water. Drinking this water may help for general wellness. You can also drink the juice of the neem leaf. To make neem juice, grind some fresh leaves with a cup of water. Strain this liquid into a cup, and your juice is ready. You can add some honey or lemon juice to taste.    

2. Papaya

Papaya leaves have been used in traditional medicine for the treatment of dengue fever. The role of papaya leaves in managing dengue has been investigated. The results are promising,Some preliminary human studies9 and trials indicate that papaya leaf extract may help support a faster rise in platelet count, white blood cells and neutrophils in some individuals. Increased platelet count could help prevent bleeding, thereby preventing the progression of the disease3,4

You can consume papaya leaf juice to help with the fever and restore normal platelet count. The juice is prepared by grinding fresh papaya leaves with a cup of water. Strain the liquid in a cup and papaya juice is ready to use.

3. Kalmegh

kalmegh

Kalmegh, also known as Andrographis peniculata, is a medicinal herb effective in a range of disease conditions. For example, in lab trials, an extract of kalmegh showed antiviral activity against the dengue virus. Therefore, kalmegh may be used to help relieve dengue symptoms5.  

You can drink kalmegh leaves or flowers, grind it and add it to a glass of water to make kalmedh juice.   

4. Dudhi

Asthma weed, known as Dudhi in Hindi, A systematic review of available evidence suggests it may help support recovery in dengue as it is an essential medicinal herb with many beneficial properties. It may help ease dengue fever and improve platelet count in people suffering from Dengue6

To use dudhi, you need to boil the paste of Dudhi leaf in water. Reduce the water to 1/4th of its volume and consume as needed. 

5. Guduchi

Guduchi or giloy is a common herb used as a remedy for many health conditions. Preliminary evidence, mostly from laboratory and traditional studies10, suggests it may help support the immune response and fight off viral infections in humans7

You can drink Guduchi juice daily to help with the symptoms of dengue. Guduchi juice is made by blending freshly chopped Guduchi with a glass of water into a smooth consistency. Strain the blended mixture to remove any solids and your Guduchi juice is ready.   

6. Kalimusli

Golden eye grass or Kalimusli is a medicinal herb effective in many conditions. The roots and rhizomes of kalimusli are used in many disease conditions. Its use may boost the immune response.  

Although, research is limited for its use, you can try taking kalimusli powder with milk to help fight off infection. 

7. Karela

Momordica charantia, known as karela in Hindi and bitter gourd in English, possesses many health benefits. Karela extract has shown inhibitory action against the multiplication of dengue virus in lab studies3.  

You can use karela as a vegetable and use it in foods and dishes. You can also make karela juice to help with dengue. To make karela juice, peel the skin, chop it into pieces, add a glass of water, and blend this mixture. Once it’s blended, strain the liquid. You can add more water to balance the taste, and your karela juice is ready.

8. Tulsi

Basil, known as Tulsi in Hindi, is an aromatic herb native to tropical regions of Asia. Tulsi leaves have been used to manage dengue fever traditionally. Tulsi has antimicrobial properties and its protective action against the dengue virus has been observed in lab studies3.   

For making tulsi tea, boil a few fresh tulsi leaves in water. Let it simmer for a while and strain it in a cup. You can add a few drops of lemon juice or a teaspoon of honey for taste.    

Though some studies show the benefits of herbs and home remedies in Dengue, evidence is limited. Therefore, there is a need for large-scale human studies to establish the true extent of the benefits of these home remedies on human health. Thus, these should only be taken cautiously and never as a substitute for medical treatment.   

Note: Home remedies discussed in this article are only supportive measures. Dengue requires proper medical supervision, and these remedies do not replace professional dengue treatment. Severe dengue can become life-threatening within hours. Always consult a qualified doctor if you suspect dengue, and seek emergency care if symptoms worsen. 

One of the most important aspects of managing Dengue fever is hydration- the patient must take lots of oral fluids to maintain BP, as the most common complication of dengue is low BP. 

Dr. M.G. Kartheeka, MBBS, MD (Pediatrics)

Warning Signs of Severe Dengue

Dengue can sometimes progress into a severe, life-threatening form, often as the fever begins to drop. Seek immediate emergency medical attention if you or someone around you notices any of these severe dengue warning signs11:

These red flags can appear suddenly and worsen quickly. Do not wait or rely on home remedies if any of these occur; go to the nearest hospital right away.

Understanding Platelet Count in Dengue

Platelets are tiny blood cells that help your blood clot and prevent bleeding. In dengue, platelet counts can drop, which is why doctors often monitor them with blood tests. Here is a general guide to platelet count in dengue (a normal range is roughly 150,000–410,000 per microlitre)12:

Importantly, platelet count alone does not determine the severity of dengue. A person can have a low count yet remain stable, or develop complications even with a higher count. Doctors assess the full clinical picture, including warning signs, hydration,  blood pressure, and  bleeding signs rather than relying on platelet numbers alone. Always let a qualified doctor interpret these results.

Dengue Care for Children

Children with dengue need especially close attention, as they can worsen  quickly and may not always describe their symptoms clearly. Supportive dengue care at home for children should focus on13:

Seek emergency care for a child who shows any warning signs like persistent vomiting, severe stomach pain, bleeding from the gums or nose, unusual drowsiness or restlessness, cold hands and feet, difficulty breathing, or markedly reduced urination. When in doubt, have the child seen by a doctor without delay.

When to Seek Medical Help?

You need to contact your healthcare specialist if you experience any symptoms of dengue.   

However, if you notice any signs of dengue worsening, you must contact your nearest hospital or healthcare provider immediately2. These include the following: 

It would be best if you did not rely on home remedies alone for dengue treatment. Consult a qualified doctor or book a dengue test as soon as you notice any symptoms, and continue the home remedies along with prescribed treatment or as suggested by your doctor.

Conclusion

Dengue is an infectious disease spread through mosquito bites. If not treated in time, dengue can progress to a severe form of infection which can be fatal. There are some herbs like kalmegh, tulsi, neem, papaya leaves, dudhi and guduchi that you can use to relieve your symptoms at home. However, these herbs should not be used as an alternative to medical treatment provided by the doctor. If you or someone around you is suffering from dengue, reach out to your healthcare provider immediately. Taking timely treatment and precautions can help prevent the infection from getting worse.

Diabetes Can Make Dengue More Lethal!

Introduction

More than 80 million people in India live with diabetes, and statistics say that more than 2 lakh people contract dengue every year1,2. Are you wondering why we are linking the two illnesses? Read on to know why.

It turns out that diabetes can worsen the complications caused by dengue, and now that winter is almost here, the dengue menace has shot up, too. If you are a diabetic, you should be extra cautious about mosquitoes this season, because dengue is more dangerous for you than for non-diabetics. 

Diabetes and Dengue: The Deadly Combination

Dengue infection in patients with pre-existing diabetes is associated with significantly higher morbidity and mortality compared to non-diabetic individuals.

Evidence from Chennai shows that among dengue patients, approximately 30% had diabetes, and these patients were more likely to experience severe complications. Diabetic dengue patients frequently present with classical symptoms such as fever, vomiting, headache, muscle and body pain, but they are also prone to severe manifestations, including reduced urine output, bleeding tendencies, pedal oedema or ascites (swelling in feet or stomach), pleural effusion (fluid in lungs), and altered sensory stimulation. Blood abnormalities such as anaemia, thrombocytopenia, and leucocytosis (reduced red blood cells and platelets and increased white blood cells, respectively) are more pronounced in diabetic patients, contributing to worse outcomes3.

A prospective study further demonstrated that dengue-infected individuals with diabetes exhibit elevated inflammatory markers (CRP, Endocan, IL-8, and perfusion index). This indicated a heightened inflammatory response that can further increase blood sugar levels and the risk of severe dengue and bleeding disorders4.

It has been shown that in some diabetes patients, dengue caused very severe complications. They may suffer from respiratory problems, persistent vomiting, sore throat that makes swallowing difficult and continuous coughing. Also, intense abdominal pain, extremely high fever and splitting headaches may be higher in diabetics with increased chances of developing Dengue Haemorrhagic Fever (DHF). DHF is a more serious form of dengue, with bleeding tendencies, a low platelet count, and possible damage to the circulatory system5,6.

Blood glucose is an important factor for viral replication, and it basically facilitates virus transmission in mosquitoes, dengue causes fever and increases metabolic rate, which can lead to a rise in fluctuation in blood sugar levels, strict monitoring is very critical.

Dr Ashish Bajaj, M.B.B.S., M.D. in Clinical Pharmacology and Toxicology

Why Diabetics Have a Higher Risk of Severe Dengue?

A common question is why diabetes appears to make dengue more dangerous. While the complete picture is still being studied, researchers point to several overlapping mechanisms that explain the dengue and diabetes risk seen in clinical practice6.

HbA1c and Dengue

HbA1c is a blood test that reflects your average blood sugar over the past 2–3 months, rather than a single reading. It is a useful marker of how well diabetes has been controlled over the longer term6.

Why does this matter during dengue? Poor long-term glucose control (a higher HbA1c) is associated with more pronounced chronic inflammation, greater changes in blood vessel function (endothelial dysfunction), and altered immune responses. Studies suggest that people whose diabetes is poorly controlled may face a higher risk of complications when they develop an acute infection like dengue. However, HbA1c alone cannot predict how severe dengue will become in an individual patient. 

In simple terms, a well-controlled HbA1c does not make you immune to dengue, but good baseline sugar control may put your body in a stronger position to cope with the stress of infection.

Blood Sugar Monitoring During Dengue

Fever and infection trigger the release of stress hormones, which can push blood sugar up, while reduced appetite, vomiting, or skipped meals can pull it down. The result is that glucose levels can swing unpredictably, which is why blood sugar monitoring during dengue needs to step up.

General guidance on how often to check (always follow your own doctor’s advice, as individual needs may differ)10:

The key message is that infection makes sugar control less predictable, so monitoring should increase during dengue rather than stay the same.

Insulin Adjustment During Dengue

During dengue, your usual diabetes regimen may need to change. Reduced food intake, vomiting, and fever can all alter how much insulin or medication your body needs. In some cases, insulin doses may need to be increased; in others, reduced to avoid dangerously low sugar11.

This is critically important: any change to insulin doses or diabetes medication during dengue must be made only by your doctor. Please do not self-adjust your insulin or stop your medication on your own based on home readings. The balance between high and low blood sugar during dengue is delicate, and getting it wrong in either direction can be harmful. Share your glucose readings and symptoms with your doctor and let them guide any adjustments.

When Diabetics with Dengue Should Be Hospitalized Earlier

People with diabetes may need extra care in the hospital than non-diabetics, because warning signs can escalate faster. Seek medical attention urgently and do not wait if you or a loved one with diabetes and dengue experience any of the following:

These can be early signals of plasma leakage or progression toward severe dengue, and prompt hospital care can be lifesaving.

Comorbidity Statistics

Real-world data underline why this matters, especially in India and South Asia12:

Given India’s very high diabetes burden and recurring dengue outbreaks, this overlap affects a large number of people every season.

Dengue Shock Syndrome

In cases of dengue in non-diabetics, patients may experience no symptoms, mild symptoms, or severe symptoms. These classical dengue symptoms may include headaches, rashes, low white blood cell levels, nausea, weakness and of course fever. As mentioned above, sometimes dengue may be very severe, increasing blood vessel wall permeability (bleeding tendency), causing the condition Dengue Haemorrhagic Fever (DHF). This condition is more common and likely to progress in diabetics6.

As this condition progresses, it may go on to something called Dengue Shock Syndrome. This is characterised by the same symptoms of internal haemorrhage, low pulse, change in mental state, and change in blood pressure that happen with DHF. Additionally, dengue shock syndrome results in multiple organ failures, failure in the circulatory system and a high risk of death7.

Overall, these findings show that diabetes significantly amplifies the severity and complications of dengue, underscoring the critical need for vigilant monitoring, prompt intervention, and individualised care in diabetic patients during dengue outbreaks.

Pathologically, dengue is characterised by high levels of inflammatory markers like CRP, endocan and IL-8. Thus, the dengue could be more fatal in patients that have co-morbid conditions of inflammation such as in diabetes.

Dr. M.G. Kartheeka, MBBS, MD(Pediatrics)

Why Does Diabetes Magnify Dengue Complications?

There is not enough evidence that tell us why diabetes makes dengue more dangerous. But doctors believe that since a person with diabetes has weak immunity, fragile blood vessels, and a higher risk of haemorrhage, symptoms of dengue tend to worsen in diabetics7. Dengue destroys a person’s platelets, which may lead to blood clotting. Together, diabetes and dengue cause a lot of damage inside the body and make it difficult for the diabetic to recover6.

What Can You Do?

Winter, especially the beginning of winter, is when dengue incidents peak. Here are a few things that diabetics can do9:

If you have diabetes, you have to be extra careful about mosquitoes. Follow the precautions mentioned above to stay healthy and safe.

When to Consider Testing?

If you have diabetes and develop fever, body ache, headache, or other dengue-like symptoms during the season, timely testing helps guide care before complications set in.

Speak with a qualified doctor about which tests are right for you. Early information supports safer, faster decisions.

Conclusion

Diabetes greatly increases the risk of severe complications and poor outcomes in dengue. This makes early detection, close monitoring, and timely management especially vital for diabetics who get dengue symptoms. Although prompt identification and medical therapy are cornerstone of management, the importance of prevention cannot be overlooked especially during periods of outbreaks.

8 Preventive Measures for Dengue That are Simple & Effective

Introduction

Dengue fever is a mosquito-borne viral infection commonly seen in tropical and subtropical regions. It is caused by the dengue virus, which is transmitted primarily by the bite of infected Aedes aegypti mosquitoes. These mosquitoes are most active during the early morning and late afternoon, although they may bite throughout the day1

Dengue can occur when an infected mosquito bites a person infected with dengue and then transmits the virus to another person through subsequent bites. The disease can cause a range of symptoms such as high fever (up to 104°F), intense joint and muscle pain, pain behind the eyes, nausea, vomiting, severe headaches, and fatigue1,2

Dengue progresses through three phases: 

As per provisional NCVBDC surveillance data, India continues to report several thousand dengue cases in 2026 (approx ~7,000+ early-year cases with low fatalities), showing ongoing transmission across states like Maharashtra, Tamil Nadu, Karnataka, and Kerala10. While it is lower than in peak outbreak years, dengue remains consistently present and active across multiple regions.

Currently, there is no widely available dengue vaccine, although some vaccines like Dengvaxia (CYD-TDV) have been approved in certain countries for people who have had a dengue infection. Another vaccine, Qdenga (TAK-003), has also been approved in select regions but is not yet widely available in India3

Given the limited availability of effective vaccines and the absence of targeted antiviral treatments for dengue, prevention remains the most effective approach for dengue management. Focusing on ways to avoid mosquito bites and reduce mosquito breeding can play a key role in protecting yourself and your community from this serious illness. 

8 Ways to Avoid Dengue Fever

1. Reduce Mosquito Breeding Sites

stagnant water

The mosquitoes that spread dengue breed in stagnant water and are found in everyday objects such as discarded tyres, plastic containers, flowerpots, septic tanks, and pet water bowls. Reducing the available breeding sites for these mosquitoes by regularly clearing out standing water can help reduce mosquito breeding and lower the risk of dengue transmission. Since Aedes mosquitoes often prefer clean, stagnant water to lay eggs in, it is important to clean potential breeding areas at least once a week3 and ensure that water storage containers are properly covered.

2. Stay in Well-Screened Houses

The mosquitoes responsible for transmitting dengue are most active around dawn and dusk. To keep them out, fit your doors and windows with fine mesh screens. Make sure the screens have no holes and keep them closed during peak mosquito hours4

3. Use Mosquito Repellents

use mosquito repellents

Using mosquito repellents can help reduce the risk of mosquito bites, especially in tropical regions or crowded areas where the risk of bites is higher. Apply creams or sprays containing 10–30% DEET, picaridin, or IR3535 when travelling or even while indoors5. For children and infants, use only age-appropriate mosquito repellents and follow the product label carefully. You can opt for mosquito patches, bands, or wipes from reputable brands. Avoid applying repellents directly to their hands or face. 

4. Wear Protective Clothing

wear cotton clothing

To reduce the risk of mosquito bites, wear long-sleeved clothing, full-length trousers, socks, and covered shoes, especially in areas where dengue is common. Light-coloured clothing is recommended, as dark colours tend to attract mosquitoes3

5. Sleep Under Mosquito-Net

sleep under mosquito net

Sleeping under the mosquito net can provide an extra layer of protection from mosquito bites for you and your children6.  

6. Keep Drains and Gutters Clean

keep drains clean

Clean and unclog drains, roof gutters, and water pipes around your home regularly. Cover all vessels and drums that are used to store water. These areas can collect stagnant water, creating breeding grounds for mosquitoes7

7. Keep Your House Airy and Well-Lit

keep your house airy and well lit

Mosquitoes often gather in dark, damp areas, so keeping your home well-lit and well-ventilated can help reduce mosquitoes in the house. Allow natural sunlight into your rooms and ensure proper airflow. Lighting camphor in a closed room for about 30 minutes on alternate days may help repel insects; however, this should not be used as a substitute for proven mosquito prevention measures. 

8. Time Your Outings

time your outings

Dengue fever isn’t limited to indoor environments; it can also occur outdoors, such as during camping trips on humid days or walks in wooded areas after rainfall. Plan your outings according to the weather and carry essential mosquito protection with you, including repellent creams, long-sleeved clothing, and netted sleeping bags. Taking these precautions can help reduce your risk of mosquito bites when you’re outside8

Dengue Care: Kids vs. Adults

When it comes to dengue, kids and adults may present with symptoms differently and may require distinct care strategies. Here is a breakdown of how dengue guidance differs for kids versus adults.
