The Health Benefits of Nasturtiums
A lot of people are familiar with Nasturtium flowers but are unaware of the health benefits of Tropaeolum majus. Want to know more about the Nasturtium medicinal uses? Let's go over them.
Great for Colds and Flu
Nasturtium leaves have a high concentration of vitamin C and are also natural antibiotics. Eating a couple of peppery leaves at the onset of a cold can stop it dead in its tracks. The gentle antibiotic action of the leaves makes them ideal for treating minor colds and flu. Eat one to two leaves three times a day for full benefits.
You shouldn't make them into tea. While the leaves will still have an antibiotic effect, boiling water will destroy the vitamin C.
My Brother Won't Touch Them
On a personal note, my brother will never eat Nasturtium leaves again. When he was a child, he developed a fever and my mom gave him a couple of leaves to eat. The next day he came out in chickenpox and still, to this day, insists that herb caused the chickenpox.
This is, of course, silly—the fever he had was the first symptom of chickenpox. Still, we've never been able to convince Andrew that this is a plant with medicinal properties.
Ancient Uses Not Scientifically Proven
While the Nasturtium was used in ancient times as a treatment for renal disease, you should avoid using too much of this medicinal plant if you suffer from kidney disease.
Using Herbal Remedies Safely
Like all herbal remedies, it is better to err on the side of caution—you should not use any herbal remedy continuously for an extended period of time. You may take the remedy daily for a week at a time at most, and then give it a break for at least a week before continuing again.
Smart Ways to Use Nasturtiums Medicinally
I have found that it is better to use nasturtiums over short periods when you need an antibiotic boost. Other than that, include a few of the leaves or flowers in a salad to boost flavor.
Avoid If Pregnant or Breastfeeding
Because there is not enough known about the effects of nasturtium during pregnancy and while breastfeeding, it should be avoided in all its forms by women who are pregnant or breastfeeding, including the flowers, leaves, and capers.
The Benefits and Uses of Nasturtiums Today
Nasturtiums are a favorite part of many people's garden. Their cheery bright faces brighten the garden even on the dreariest day and can be used for a pop of color in cuisine as well. As cut flowers go, they look great but don't last too long.
You could, however, grow them in a pot inside as long as they get full sunlight and the potting soil is not too rich.
The flowers are often added to salads to give them some color and the leaves add a great peppery taste to salads as well.
Nasturtium's seeds are often used in place of capers.
Just about the whole plant is useful.
The botanical name for the plant that is being referred to here is Tropaeolum Majus and should not be confused with Nasturtium Officinale. The latter is more commonly known as Watercress.
The Uses of Nasturtiums in History
These sunny, healthy plants originated in South America and were widely used by the Mesoamericans for urinary tract infections, kidney problems, and for their general antibiotic action.
In Ancient Times
The leaves were used to prevent scurvy, to supplement the daily diet, and to add flavor. The peppery leaves were very popular and the seeds were a prized delicacy.
In fact, they were considered so important that no home was without a nasturtium plant if they could avoid it. The plants are also so undemanding that they were perfect for the rocky soil of the Andes.
In South America, the plant was a traditional remedy for renal disease. Modern scientific research hasn't found the plant beneficial in this respect. If you have renal disease, you must consult your physician before trying any herbal remedies.
In the Middle Ages
In the 1600s in England, the Tropaeolum majus was a valued medicinal plant but was known as Indian Cress (Because of their similarity in flavor to Watercress.)
The high vitamin C content made the so-called "Indian Cress" a highly nutritious complement for the diet and was used to ward off scurvy.
Wherever they have been introduced, nasturtiums have quickly become a firm favorite because of their medicinal and culinary uses.
I always make sure that I have a bed of these sunny little flowers and always look forward to spring and summer when they burst with color. They come up on their own without much interference from me.
Once they've become established, they spread nice and quickly.
Tropaeolum majus in the Garden
Grow Your Own Tropaeolum majus
Nasturtiums are very easy to grow. They thrive in poor soil so don't use a lot of compost when planting them. They can grow just about anywhere as long as they are in full sun.
I had a very rocky patch of ground in my garden - I think it's where the builders dumped the rubble when they built the house - and nothing would grow there. I planted some yarrow to help condition the soil and edged the patch with nasturtiums. It is now lovely and green.
In Warmer Climates
In the warmer parts of the world, nasturtiums can be grown year-round. They tend to self-seed and, if conditions are right, they'll take over. They form a small leafy bush that creeps along the ground and provides great ground cover.
Where It Is Colder
They are frost tender and so will die down completely in winter in colder areas. Not to worry though, in spring they will come up again in full force.
Try growing different colors and varieties - they will cross-pollinate and you may get some interesting results.
I've even had little plants coming up all over the compost heap - they made a really good show there and covered it beautifully. Paradoxically, the compost heap gets very little sun so it just goes to show how hardy these little guys can be.
Nasturtiums come in a lot of different colors and there are also now varieties that have a variegated leaf - these are extremely pretty and very rewarding for the home gardener.
Make a Stunning Feature
Collect a few tin cans and drill holes into the bottom of them. Put a layer of stones at the bottom to aid drainage and add some soil. Plant a different color plant in each "pot". Line up against a sunny wall and wait for the profusion of flowers.
My brother battled with pronunciation when he was little and so he always said, "Nasty 'ems." To this day we tease him about his "Nasty 'ems" and chicken pox plant.
Where Nasturtiums Came From
The Beauty Benefits of Nasturtiums
The high vitamin C content in the leaves makes these potent little plants great for your overall health and well-being. Eating a couple of leaves a day is said to help clear up acne.
The ancients used to use it as a hair tonic and scientific research actually backs this up - Nasturtium tea applied to the head stimulates the capillaries and so increases circulation and the flow of nutrients to the scalp.
The tea can also be used in place of a toner for oily skin.
Make your Own Nasturtium Tea
Place one cup of flowers and/ or buds in a liter of water in a pot. Cover and allow to simmer for 15 minutes. Strain and store in the refrigerator.
For hair growth, massage into scalp before rinsing hair. Try using daily.
For skin care, apply using a cotton ball and then rinse off with warm water.
An Ultra-Effective Hair Treatment
This is a bit more effort but makes is great for the hair. Mix one cup each of nettle, nasturtium and rosemary into two liters of water. Simmer in a closed pot for 15 minutes. Allow it to cool and then strain for use. Massage into your scalp before rinsing out. You can toss the used leaves into the compost heap so nothing goes to waste at all.
Refrigerate any leftovers.
The Value the Nasturtium in the Garden
Nasturtiums act as a wonderful ground cover and can shade the roots of plants that tend to be more sensitive to the hot sun. The nasturtium plant stays quite low to the ground and so can also add interest to your garden.
I always make sure that I plant a few of the seeds in my compost heap - this turns a somewhat ugly heap into a much prettier show. (The leaves look lovely and lush - there aren't as many flowers though.)
Nasturtiums can be quite useful when it comes to acting as a trap crop. Plant them around your veggie patch to lure insects away from your vegetables.

Nasturtiums in the Kitchen
Nasturtium leaves make a great substitute for rocket in a salad. Pick them as close to the time needed as possible and rinse before adding to the salad.
The flowers are great for adding color to salads and decorating food. Freeze them into ice cubes to create a pretty addition for summery drinks.
Nasturtiums seeds can be pickled in vinegar to use as a great substitute for capers. Store for at least 3 weeks before using to allow the flavors to develop fully.
Nasturtium and Watercress on Toast
I'm not the best cook in the world, but this simple recipe allows me to fake it.
- Sourdough bread
- Plain cottage cheese
- A handful of fresh watercress
- One nasturtium leaf, chopped
- One nasturtium flower and leaf, whole
- A few slices of red onion
- Salt and pepper to taste
Toast your bread as you normally would. Top it with cottage cheese. Then slice the watercress and nasturtium leaf up finely. Mix them together and sprinkle them over the cottage cheese. Finish with the onion.
Season to taste if necessary, garnish with the Nasturtium flower and leaf, and enjoy.

People Also Ask
Do nasturtiums like sun or shade?
These cheery herbs love the sun. While they'll tolerate a little bit of shade, they require at least six hours of direct sunlight a day to thrive.
Do nasturtiums come back every year?
The plants are annuals, meaning that they die down completely in winter. You don't need to worry, however, they'll start popping up in the spring again. They grow easily enough from scattered seed if you'd like a showier display.
What are nasturtiums good for?
- The flowers are edible, making for a pretty addition to salads, cakes, and drinks
- The seeds make a good substitute for capers
- The peppery leaves are an excellent way to spice up a salad, and deliver a natural antibiotic boost to boot.
- Nasturtium Tea, cooled and rubbed into the scalp, will promote hair growth.
- In the garden, the flowers attract pollinators, and the leaves act as a trap crop. They're a valuable friend for the avid veggie gardener for these two reasons.
Where should I plant nasturtiums?
They prefer a spot that gets a lot of sun during the day. The amount of light they receive is more important than the soil quality. These plants thrive on neglect and will produce better blooms in poor soil with little compost in it.
Nitrogen-rich soil will boost the production of the leaves at the expense of the flowers.
They'll do well in rocky soil as well, as long as it drains relatively well. They don't like their roots to stay damp, so won't do well in areas with a great deal of clay.
You may plant them in a large pot as well.
Will nasturtiums climb?
Yes. They can actually take over quite quickly under the right conditions. If you'd like to take advantage of their climbing ability, consider installing a trellis or some other support structure near them.
Before long, they'll grow over it.
Do nasturtiums spread?
Yes, as long as the growing conditions are right. They can actually become a little like weeds in warmer climates, but they're so pretty, no one cares.
Why do nasturtiums turn yellow?
Yellow leaves point to one of several problems.
Too Much Water
Dig away a little of the topsoil on a dry day and feel whether or not it's damp. If it's very moist, you may have a drainage problem.
Dig a hole around 12 inches deep and 12 inches wide next to the plant. Fill it with water and allow the water to drain away. Refill it with water again, but this time check the hole at hourly intervals to see how fast the water drains away.
If the water takes longer than an inch an hour to drop, you'll need to improve the drainage in the area. As nasturtiums don't like rich soil, you may do this by digging in some river sand.
Are nasturtiums poisonous to dogs?
No. The RSPCA confirms that they are not toxic for dogs, cats, or horses.
Do nasturtiums attract bees?
Yes, they also attract other beneficial pollinators such as butterflies.

Questions & Answers
Question: Will my potted nasturtium flower next year?
Answer: It depends on whether or not it is in the right spot. As long as it is getting lots of sunlight, it should. Also, don't be too heavy with the nutrients in the soil. Too much nutrition will make it grow lovely, lush leaves, but it will end up having fewer flowers.
Question: If Nasturtium tea on the forehead increases capillary activity, can it be helpful for erectile dysfunction?
Answer: No, not really because the blood flow necessary to maintain an erection is from an artery. Capillaries are closer to the surface of the skin.
Question: Is Nasturtium an annual plant?
Answer: It depends on where you live. They don't like frost or snow, so they die down in winter in cold areas. When I lived on the coast, however, they didn't die off in winter at all.
Question: Would it be harmful to eat the leaves of Nasturtiums every week?
Answer: No, a few leaves once or twice a week in a salad will boost your health.

What are your Thoughts on the Common Nasturtium Now?
Fiona (author) from South Africa on July 06, 2019:
I'm in KZN and we've always got them in the garden. I've used them instead of rocket as well.
Brenda Gamba on July 04, 2019:
I have always used the leaves as an antibiotic. Wash, dry and chew. Even my children , at the onset of a sore throat, would just go to the garden, pic sum leaves, wash it and eat it. Works like a bomb. Bit of a tang in the leave, but bearable. I live in South Africa. I have been to Simonstown, in the Western Cape and stand in awe of the nasturniums that blooms there in Spring.
Fiona (author) from South Africa on May 26, 2016:
I was listing what it was used for in ancient times - in Meso-America, it was used for kidney complaints. Today, however, it's main value is as a natural antibiotic and a way to boost Vitamin C intake.
It is never a good idea for anyone to take any herbal remedy continuously for an extended period because there is a risk of toxic buildup depending on which herb is used. It is never advisable to use a herbal remedy for longer than about a week to two weeks at a time without a break.
This is particularly true when it comes to people with kidney disease. Thanks for pointing that out - I have amended the article accordingly.
Sydney Silver from Los Angeles on May 25, 2016:
Hi thanks for the article :)
U say they were used for kidneys but all over the net I see if u have kidney disease you shouldn't use nasturtium? Do u know which one it is? Thanks!!
Fiona (author) from South Africa on April 15, 2016:
Hi Lachlan, yes, they are very hardy little plants. I also love putting the flowers in the salad to brighten it up.
Lachlan Turner on April 12, 2016:
I have my Nasturtiums in a corner of the garden that gets virtually no direct winter sun(I live in Australia and have a mediterranean temperate climate) and the plant is there virtually all year. Died last Summer from the heat but has come back through reseeding. When ever I run out of lettuce or have no spinach for sandwiches I pick a few leaves and use them. Also great as a beneficial insect attractor. Very useful and pretty plant.
Pamela Lipscomb from Charlotte, North Carolina on August 13, 2014:
It's great to see we are getting back to natural ways of healing and eating. Great for hon Nasturtiums!
Fiona (author) from South Africa on December 27, 2013:
Thanks Loveofnight - it is worth a look.
Loveofnight Anderson from Baltimore, Maryland on December 26, 2013:
i will be on the look out for this plant, thanks for the share.
Fiona (author) from South Africa on December 24, 2013:
Hi Sweetie-Pie, well rather hang on with the planting until spring then but do try them, they are a really cute little plant
SweetiePie from Southern California, USA on December 24, 2013:
I used to love picking Nasturtiums out of my mom's garden, and eating these in salads at a kid. I might have to try to grow some myself, although it is slightly the dormant season for plants being winter here.
Fiona (author) from South Africa on December 22, 2013:
Hi Poetryman, normally I would agree with you but, when it comes to herbs that I know, I am a little more flexible.
poetryman6969 on December 22, 2013:
I am a little reluctant to eat flowers from my garden. But an interesting idea.
Fiona (author) from South Africa on December 19, 2013:
Thanks PS, like the angels bit. If you get the chance give them a try - they taste a lot like rocket.
Patricia Scott from North Central Florida on December 19, 2013:
Hi I had NO idea ....I adore them but did not realize they had healthful properties as well. Thanks for sharing this with us.
Angels are on the way to you and yours this morning ps

I love nasturiums...it is one of the first plants I grew as a child, so it is a nice memory. The orange color is so refreshing.
Elenin from So Cal on December 12, 2011:
Great article. I have allowed Nasturtiums to grow because I liked their blooms and hoped that they would attract bug eating birds. I was totally unaware of any health benefits. I am starting to get a cold so I tried your remedy. Not bad, might well use these in a stir fry in the future.
It appears that your section about “Where Nasturtiums Came From” did not make it on the Hub, FYI.
Thanks for a useful Hub and the reminder to look at all that Nature offers.
