Ginger: Traditional Remedy, Everyday Spice and What Modern Research Says

Walk into many Caribbean kitchens and you are likely to find a piece of ginger somewhere nearby.

It may be sitting beside the garlic and onions, simmering in a pot, steeping in a cup of tea, blended into a drink, or waiting to become part of an old family remedy.

For generations, ginger has been much more than a seasoning. Known scientifically as Zingiber officinale, this familiar root has travelled through cultures and generations as both food and traditional medicine. Long before scientists began studying gingerols, shogaols and the other natural compounds found in ginger, people were already reaching for it when they experienced nausea, digestive discomfort, colds and other everyday complaints.

In Guyana and across the Caribbean, that kind of traditional knowledge is familiar. Many of us grew up seeing plants, herbs, roots and spices used not because somebody had read about them in a scientific journal, but because the knowledge had been handed down from one generation to another.

Modern research now gives us another way to examine those traditions. Sometimes science supports what people have observed for generations. Sometimes the evidence is still developing. And sometimes research shows us that a popular claim may have been exaggerated.

The two do not have to be enemies.

Traditional knowledge gives us experience. Science gives us another way to investigate that experience.

A Root With a Long History

Ginger originated in tropical parts of Asia and eventually spread throughout much of the world. Its distinctive flavour made it valuable as a spice, but its traditional medicinal uses also travelled with it.

Different cultures have used ginger for digestive complaints, nausea, cold and flu symptoms, aches and other ailments.

Traditional use alone cannot prove that every remedy works exactly as people believe it does. At the same time, generations of traditional experience should not simply be dismissed because every use has not yet been confirmed in a modern clinical trial.

Traditional practices often give researchers questions worth investigating.

Ginger is a very good example.

Ginger and Nausea

One of ginger's best-known traditional uses is for an unsettled stomach.

Many people know the experience of drinking ginger tea when they feel nauseated. Of all the health claims surrounding ginger, nausea is also one of the areas that has received considerable scientific attention.

Research suggests that ginger may be helpful for certain forms of nausea, particularly nausea and vomiting associated with pregnancy.

But there is an important distinction.

That does not mean ginger works equally well for every kind of nausea.

Studies investigating ginger for motion sickness, for example, have not produced the same convincing evidence. Research involving chemotherapy-related nausea has also produced mixed results.

So instead of turning ginger into a miracle remedy and saying that it "cures nausea," it is better to understand what the evidence actually tells us:

Ginger may help with certain kinds of nausea, but the cause of the nausea matters.

That is a much more useful way of looking at natural remedies.

Why Ginger Has Such a Reputation for Digestion

Ask someone why they drink ginger tea and you may hear:

"It settles my stomach."

That expression has survived for generations, and there may be some science behind the observation.

Small clinical studies have found that ginger can influence movement within the digestive system and may help the stomach empty its contents more quickly.

This is interesting because delayed stomach emptying can contribute to uncomfortable fullness in some people.

But digestive symptoms are complicated.

Gas, bloating, indigestion, abdominal discomfort and persistent stomach pain can have many different causes. Ginger should therefore not be presented as a guaranteed treatment for every digestive complaint.

For some people, a traditional cup of ginger tea may be comforting.

Persistent, severe or unexplained digestive symptoms, however, should not simply be covered up with home remedies. Finding the underlying cause matters.

The Warming Compounds Inside Ginger

That familiar heat you feel when biting into fresh ginger is not accidental.

Ginger contains naturally occurring compounds including gingerols and shogaols. These compounds have attracted scientific interest because of their antioxidant and anti-inflammatory activity.

Researchers have investigated ginger in relation to inflammatory markers as well as conditions involving pain.

Among the areas studied are menstrual cramps and osteoarthritis.

Some research suggests ginger may help reduce the severity of menstrual cramps. Studies involving osteoarthritis have also suggested possible benefits, although limitations in the available research mean we should be careful about making strong promises.

This is where one small word becomes extremely important:

May.

A plant can have promising properties without becoming a cure for everything.

Natural remedies deserve neither exaggeration nor dismissal.

Ginger, Blood Sugar and Heart Health

The internet is filled with claims that ginger lowers blood sugar, cholesterol and blood pressure.

There is scientific interest in these areas, and research continues.

Reviews of clinical studies suggest that ginger supplementation may influence certain measurements associated with blood glucose, inflammation and other aspects of metabolic health.

That is interesting research.

But it does not mean someone with diabetes, high blood pressure, high cholesterol or heart disease should replace prescribed treatment with ginger.

There is an enormous difference between saying:

"Research suggests ginger may influence certain aspects of metabolic health."

and saying:

"Ginger treats diabetes or heart disease."

Those are not the same claim.

Natural-health education becomes more useful when we can appreciate promising research without turning every promising result into a cure.

The Ginger Tea We Know During Cold and Flu Season

For many families, ginger becomes especially popular when somebody has a cold.

A warm cup of ginger tea can be comforting when the throat feels irritated, when you feel chilled, or when you simply want something warm to drink.

Ginger is commonly combined with lemon, honey and other traditional ingredients.

But comfort and cure are two different things.

Ginger should not be presented as a cure for influenza or other respiratory infections simply because it has traditionally been used when people are sick.

And that does not make the tradition worthless.

Sometimes the value of a traditional remedy is comfort.

A warm drink can help with hydration. Honey may soothe the throat. Rest matters. And the familiar taste and warmth of a traditional preparation can simply make an uncomfortable day feel a little easier.

Not everything useful has to be a cure.

A Simple Cup of Fresh Ginger Tea

One of the things I appreciate about ginger is its simplicity.

You do not necessarily need an expensive supplement.

Fresh ginger itself is food.

For a simple ginger tea, wash a small piece of fresh ginger and slice or grate it. Add it to hot water and allow it to steep for around five to ten minutes.

If you prefer a stronger flavour, you can use a little more ginger or allow it to steep longer.

Some people add lemon or honey according to taste.

There is no need to make ginger tea painfully strong because you believe stronger automatically means better.

More is not always better when working with herbs and spices.

Ginger Belongs in the Kitchen Too

Sometimes we become so interested in the medicinal possibilities of a plant that we forget the simplest way of using it.

Eat it.

Fresh ginger can add flavour to soups, broths, marinades, meat, fish, vegetables, sauces, stir-fries, baked foods and homemade drinks.

A small piece can also be blended into fruit or vegetable drinks.

Because raw ginger has a powerful flavour, it is usually better to begin with a small amount and adjust according to taste.

Using herbs and spices regularly as part of ordinary food is one of the oldest forms of natural living.

What About Ginger for Hair?

This is where we need to separate a popular claim from what research has actually demonstrated.

Ginger has a long history of use in different traditional hair and scalp preparations, and ginger extracts can still be found in some commercial hair products.

But you may also see claims online that ginger is a scientifically proven hair-growth treatment.

The evidence does not support making that promise.

One laboratory study examining 6-gingerol, an important active constituent of ginger, actually found inhibition of hair-follicle growth under the experimental conditions studied.

That does not mean that putting ordinary ginger into a hair preparation will automatically cause someone's hair to fall out. A controlled laboratory experiment involving a particular compound is not the same thing as ordinary traditional use of the whole root.

But it does give us a good reason to be careful about advertising ginger as a proven hair-growth stimulant.

This is an important lesson in natural-product education.

Traditional use, laboratory research and proven clinical treatment are three different things.

Ginger and the Scalp

Ginger contains compounds that have demonstrated antimicrobial, antioxidant and anti-inflammatory properties in research.

Those properties help explain why ginger continues to attract interest for cosmetic and scalp applications.

But research on topical ginger use in humans remains limited.

So if somebody has persistent dandruff, eczema, psoriasis, a fungal infection or another scalp condition, simply applying ginger without understanding the problem may not be the best approach.

And this brings us to something especially important in scalp care:

Not all that flakes is dandruff.

A flake is a symptom.

What is happening underneath the flake is what matters.

Dandruff itself can vary in appearance, and other scalp conditions can also cause scaling and flaking. That means we should be careful about trying to diagnose a scalp problem simply by looking at whether the flakes appear dry, oily, large or small.

Sometimes what looks like ordinary dandruff may have another cause.

Understanding the scalp matters more than repeatedly applying stronger remedies to the flakes.

Natural Does Not Mean Use Without Caution

I believe strongly in learning about natural remedies.

But "natural" should never be confused with "incapable of causing irritation."

Ginger is biologically active.

That is part of the reason we are interested in it.

When taken orally, ginger can cause heartburn, abdominal discomfort, diarrhoea, or irritation of the mouth and throat in some people.

Concentrated supplements also deserve more consideration than simply using ginger as an ordinary food ingredient.

People taking medication should be particularly careful with regular medicinal or supplemental use because herbs and medicines can sometimes interact.

Pregnant women considering concentrated ginger supplements should also discuss their use with an appropriate healthcare professional, even though ginger has been widely studied for pregnancy-related nausea.

The same common sense should apply when putting ginger on the skin or scalp.

Fresh ginger can feel extremely hot on sensitive skin.

Burning does not prove that a natural remedy is working.

If something causes significant irritation, your skin is telling you something.

When experimenting with ginger cosmetically, a diluted preparation and a small-area test are more sensible than covering a large area with concentrated raw ginger juice.

Traditional Knowledge Should Not Be Thrown Away

Natural remedies often create an unnecessary argument.

On one side, we sometimes hear:

"Our ancestors used it, so it must work for everything."

On the other side:

"Science hasn't proven it, so it is useless."

I do not believe either extreme gives us the whole picture.

Our ancestors did not have modern laboratories, but they were observers.

People learned which plants they used, how they prepared them, what happened when they used them and which practices they considered valuable enough to pass to their children.

That knowledge deserves respect.

Modern research gives us additional tools.

Scientists can isolate compounds, measure biological effects, compare groups of people, identify risks and sometimes explain why a traditional practice may have produced a particular result.

Research can also show us when a claim has become exaggerated or when something that appears harmless deserves more caution.

We do not have to destroy traditional knowledge to accept science.

And we do not have to reject science to respect traditional knowledge.

We can learn from both.

The Healthy Choice

Ginger is more than a fashionable "superfood."

It is an ancient spice, an everyday food, a traditional household remedy and a plant that continues to attract serious scientific research.

Some of its traditional uses have stronger scientific support than others. Some remain under investigation. Some popular claims have very little evidence behind them.

And that is perfectly all right.

A natural remedy does not have to cure everything to have value.

Enjoy ginger in your food.

Make your traditional cup of ginger tea.

Learn what previous generations knew about it.

Pay attention to what modern research continues to discover.

And most importantly, learn the difference between tradition, promising research and a proven medical treatment.

That is how traditional knowledge stays alive without becoming misinformation.

Nature gives us the plant. Tradition gives us experience. Research helps us understand it.

Small Steps Create Big Shifts

Confidence doesn’t always arrive with a bold entrance. Sometimes, it builds quietly, step by step, as we show up for ourselves day after day. It grows when we choose to try, even when we’re unsure of the outcome. Every time you take action despite self-doubt, you reinforce the belief that you’re capable. Confidence isn’t about having all the answers — it’s about trusting that you can figure it out along the way.

The key to making things happen isn’t waiting for the perfect moment; it’s starting with what you have, where you are. Big goals can feel overwhelming when viewed all at once, but momentum builds through small, consistent action. Whether you’re working toward a personal milestone or a professional dream, progress comes from showing up — not perfectly, but persistently. Action creates clarity, and over time, those steps forward add up to something real.

You don’t need to be fearless to reach your goals, you just need to be willing. Willing to try, willing to learn, and willing to believe that you’re capable of more than you know. The road may not always be smooth, but growth rarely is. What matters most is that you keep going, keep learning, and keep believing in the version of yourself you’re becoming.

In Guyana, Lantana camara is a familiar plant. It can be found growing along roadsides, around yards, near fences, in open land and in bushy areas. Its clusters of small yellow, orange, pink, red or mixed-coloured flowers make it easy to notice, yet many people may not realize that this common plant has a long history of traditional medicinal use.

Lantana camara is also one of the plants featured in my book The Plant Next Door, which looks at familiar plants growing around us and the traditional knowledge connected to them.

Across different cultures, lantana has been used in traditional medicine for skin complaints, wounds, fever, coughs, stomach problems, swelling, rheumatic pain and other conditions. Modern scientific research has also found that the plant contains numerous active compounds, including triterpenes, flavonoids, phenolic compounds and iridoid glycosides. These compounds have been studied for antibacterial, antifungal, anti-inflammatory, antioxidant, wound-healing and other biological activities. (PubMed Central (PMC))

Traditional Uses of Lantana Camara

Traditional use of lantana varies from country to country, but the leaves have been among the most commonly used parts of the plant.

Ethnobotanical records describe preparations of lantana for complaints such as itching, cuts, ulcers, swelling, coughs, bronchitis, asthma, eczema, chicken pox, stomachache, toothache, headache, rheumatism, scabies and wounds. In some communities, leaf decoctions and infusions have also been used traditionally for diarrhoea, fever and other ailments. (PubMed Central (PMC))

These traditional uses have encouraged scientists to study the plant more closely.

Anti-Inflammatory Benefits

One of the important areas of research surrounding Lantana camara is inflammation.

Laboratory and animal studies have reported anti-inflammatory activity from lantana leaf extracts. An aqueous leaf extract has also demonstrated analgesic, or pain-relieving, effects in experimental research. (PubMed Central (PMC))

This is especially interesting because traditional medicine has long used lantana in preparations associated with swelling, rheumatic discomfort and pain.

Inflammation is part of the body's natural response to injury and infection, but excessive or prolonged inflammation contributes to many health problems. The anti-inflammatory compounds found in lantana are therefore an important area of medicinal-plant research.

Antibacterial Activity

Lantana has demonstrated antibacterial activity against several types of bacteria in laboratory studies.

Researchers have reported activity from leaf extracts against organisms including Escherichia coli, Proteus vulgaris, Vibrio cholerae, Bacillus subtilis, Klebsiella pneumoniae, Staphylococcus aureus and Pseudomonas aeruginosa. (PubMed Central (PMC))

This antibacterial activity may help explain why lantana has traditionally been used as an antiseptic and in preparations for wounds and certain skin complaints.

Antifungal Activity

Lantana has also been studied for antifungal properties.

Extracts and essential oils from the plant have demonstrated activity against certain fungi in experimental research. (PubMed Central (PMC))

This has contributed to scientific interest in lantana for skin and topical applications, particularly because fungal organisms can contribute to several common skin and scalp conditions.

Wound-Healing Activity

One of the more interesting medicinal areas associated with lantana is wound care.

Traditional healers in different regions have used lantana leaves on cuts, ulcers and wounds. Modern research has also reported wound-healing activity from both ethanol and water extracts of lantana leaves in experimental studies. (PubMed Central (PMC))

Wound healing involves several processes, including inflammation control, protection against microorganisms and rebuilding damaged tissue. Because lantana has demonstrated both antimicrobial and anti-inflammatory activity, researchers continue to investigate its possible role in this area.

Antioxidant Properties

Lantana leaves and flowers contain natural compounds with antioxidant activity.

Laboratory studies using methanol extracts from the leaves and flowers have demonstrated significant antioxidant properties. (PubMed Central (PMC))

Antioxidants help neutralize unstable molecules known as free radicals. Excessive oxidative stress can damage cells and tissues, which is why antioxidant-rich plants continue to receive significant scientific attention.

Blood Sugar Research

Lantana has also been investigated for its possible effects on blood glucose.

Experimental studies involving aqueous leaf extracts have reported antidiabetic or blood-glucose-lowering activity. (PubMed Central (PMC))

This area remains an active field of research. The findings are important because they show that compounds within the plant can affect processes involved in glucose metabolism.

They do not, however, establish lantana as a replacement for prescribed diabetes treatment.

Digestive Uses and Diarrhoea

Traditional preparations of lantana leaves have been used for digestive complaints, including diarrhoea and stomachache.

Experimental studies have also reported moderate antidiarrhoeal activity from ethanol leaf extracts. (PubMed Central (PMC))

This provides another example of a traditional use that has attracted scientific investigation.

Respiratory Uses

Lantana has a history of traditional use for respiratory complaints.

Ethnobotanical records document its use for coughs, catarrh, asthma and bronchitis in different parts of the world. (PubMed Central (PMC))

Some traditional preparations have involved the leaves, while others have used different plant parts depending on local practice.

Although these historical uses are well documented, much of the modern research into lantana's respiratory applications remains experimental rather than based on large human clinical trials.

Fever and Traditional Remedies

Lantana has also been traditionally associated with fever.

Different cultures have used leaf preparations for febrile illnesses and malaria-related traditional treatments. Researchers have subsequently investigated lantana extracts against Plasmodium falciparum, the parasite responsible for malaria, and some extracts have demonstrated notable laboratory activity, including activity against both chloroquine-sensitive and chloroquine-resistant strains. (PubMed Central (PMC))

These findings are scientifically significant and have encouraged calls for further investigation.

Antiparasitic Research

Lantana is also being studied for activity against parasites.

Researchers have reported activity against organisms associated with leishmaniasis, malaria and certain parasitic worms and nematodes. (PubMed Central (PMC))

Some of these findings have been strong enough for researchers to identify lantana's antiparasitic compounds as an area deserving further investigation.

Insect-Repellent and Insecticidal Activity

Lantana has a long history of use in plant-based pest control.

Modern studies have found that different lantana extracts can have insecticidal and larvicidal activity against mosquitoes, termites, moths, weevils and other insects. Its essential oil has also demonstrated mosquito-repellent effects. (PubMed Central (PMC))

These properties are particularly interesting in tropical regions, where mosquitoes and other insects are a constant part of daily life.

Possible Protective Effects on the Liver

Some experimental research has reported hepatoprotective activity from methanol extracts of lantana leaves. (PubMed Central (PMC))

This does not mean that eating the plant protects the liver. Lantana also contains compounds capable of causing liver toxicity, particularly in animals, making dosage, preparation and plant chemistry extremely important.

The same plant can contain compounds showing different effects under different experimental conditions.

Cancer Research

Lantana has attracted interest in cancer research because certain extracts and isolated compounds have demonstrated cytotoxic and antiproliferative activity in laboratory studies.

A recent scientific review reports anticancer and antiproliferative activity among the biological effects associated with lantana constituents. (PubMed Central (PMC))

This research is investigating compounds within the plant as possible starting points for future medicines. It should not be interpreted to mean that lantana itself is a proven cancer treatment.

Hair and Scalp Uses

The antimicrobial, antifungal, antioxidant and anti-inflammatory activity associated with lantana also makes the plant interesting for scalp and hair-care research.

Traditional topical use of lantana has centred more strongly on skin, wounds and infections than on scientifically established hair growth. However, its activity against microorganisms and inflammation may explain why leaves have sometimes been incorporated into traditional cleansing and topical preparations.

For scalp care, the condition causing itching, scaling or irritation still needs to be understood. A plant preparation cannot treat every scalp condition simply because it has antimicrobial properties.

Skin Benefits

The skin is one of the areas where lantana's traditional reputation and scientific research overlap most clearly.

Traditional uses have included:

• wounds and cuts;

• itching;

• ulcers;

• eczema;

• swelling;

• scabies; and

• other skin complaints.

Modern research has documented antibacterial, antifungal, anti-inflammatory and wound-healing activity from different lantana extracts. (PubMed Central (PMC))

These properties are among the strongest reasons lantana continues to attract interest as a medicinal plant.

Active Compounds in Lantana

The medicinal activity of lantana comes from its complex chemistry.

Researchers have identified numerous classes of natural compounds, including:

• triterpenes;

• flavonoids;

• phenylpropanoids;

• iridoid glycosides;

• steroids;

• saponins;

• polyphenols;

• coumarins;

• alkaloids; and

• other phenolic compounds. (PubMed Central (PMC))

Different compounds may contribute to different biological effects.

This is one reason scientists often study individual extracts and isolated compounds rather than treating the entire plant as though every part has exactly the same properties.

An Important Safety Side of Lantana

Lantana is medicinally interesting, but it is also a plant that must be treated with respect.

Its toxicity is particularly well documented in grazing animals. Certain compounds known as lantadenes, especially lantadene A and B, can damage the liver. Poisoning in livestock has been associated with jaundice, photosensitivity and serious liver injury. (PubMed)

Unripe green fruits have also been reported as toxic to humans. (PubMed)

For this reason, lantana should not be treated as an ordinary edible herb simply because it has medicinal uses.

Traditional medicinal knowledge includes not only knowing which plant is used, but also understanding the plant part, preparation and method of use.

Traditional Knowledge and Modern Research

Lantana camara shows why traditional plant knowledge remains important.

Long before laboratories identified triterpenes, flavonoids and other compounds within lantana, people were already using the plant in traditional preparations for wounds, swelling, fever, respiratory complaints, digestive problems and skin conditions.

Today, researchers have demonstrated antibacterial, antifungal, anti-inflammatory, antioxidant, wound-healing, antiparasitic and other biological activities within the plant. (PubMed Central (PMC))

Research continues to deepen our understanding of a plant that people have known for generations.

The Plant Next Door

Lantana camara is one of the plants featured in The Plant Next Door because it represents exactly what the book is about: recognizing the knowledge and potential contained in plants growing all around us.

A colourful shrub beside a road or fence may carry generations of traditional knowledge and contain compounds that scientists are still investigating today.

That does not make every traditional plant a cure for every illness.

It does remind us why the plants growing around us deserve to be identified, studied and remembered.

The Healthy Choice

Lantana camara is far more than an attractive flowering shrub.

Its traditional uses include preparations for wounds, skin complaints, swelling, digestive problems, fever, respiratory complaints and pain. Modern scientific studies have found antibacterial, antifungal, anti-inflammatory, antioxidant, wound-healing, antiparasitic and other biological activities within extracts and compounds from the plant.

At the same time, its known toxicity means it should be treated with knowledge and care.

Lantana gives us something valuable: an opportunity to see how traditional plant knowledge and modern scientific investigation can meet around a plant that has been growing beside us all along.

Nature gives us the plant. Tradition carries the knowledge. Research helps us understand its medicinal possibilities.
