What Is A Rambutan?
It is a medium-sized tropical tree and belongs to the family Sapindaceae. Scientifically called Nephelium lappaceum, the name rambutan also refers to the delicious fruit (which we are going to talk about) this tree produces. It is native to the Malay-Indonesian region and certain other regions of Southeast Asia.
Also spelled rambotan, ramboutan, rambustan, and ramboetan, the fruit is closely related to other tropical fruits like the lychee, longan, and mamoncillo. In fact, in the native language, rambut means hair. This is with reference to the numerous hairy protrusions of the fruit. In Vietnamese, the fruit is called chom chom (which means messy hair), referring to the spines covering its skin.
That’s a little about this seemingly mysterious fruit. But wait, why are we even talking about it?
What Is Rambutan Good For?
Though the fruit is small, it contains a considerable amount of vitamin C – a nutrient that boosts immunity and flushes toxins out of your body.
Rambutan contains copper as well, another mineral that works in tandem with iron to improve the health of your blood vessels and blood cells (as it is also a good source of iron).
There are several other benefits, which we have saved for later. But before that, how about taking a peek into the history of rambutan?
What Is The History Of Rambutan?
Like we saw, rambutan is native to Malaysia and Indonesia. This is where the widest cultivars of the fruit are found. Around the 14th century, the Arab traders introduced rambutan to East Africa. And in the 19th century, the Dutch introduced this fruit to South America. In 1912, the fruit traveled from Indonesia to the Philippines.
We don’t want to delve too deep into the history and keep you waiting. So let’s get to the benefits. But just before that, how about taking a look at the nutrients this wonder fruit contains?
What Is The Nutritional Profile Of Rambutan?
A hundred grams of rambutan contain about 84 calories. And a serving of the fruit has just 0.1 gram of fat. It also has 0.9 gram of protein. And 100 grams of this fruit also contain 40 percent of the vitamin C you require daily and about 28 percent of iron.

What Are The Benefits Of Eating Rambutan?
Rambutan is rich in antioxidants that fight the free radicals and prevent any ailment that they might cause. These include cancer, inflammation, and even heart disease. The abundance of certain vitamins and the delectable taste make this fruit a must-have on one’s plate.
1. Can Aid In Diabetes Treatment
A Chinese study talks about how rambutan peels possess anti-diabetic properties. Diabetic mice induced with the phenolic extracts of rambutan peels had shown a reduction in fasting blood glucose levels (1).
2. Can Prevent Weight Gain
There is no specific research that suggests how rambutan, by itself, can prevent weight gain. However, fruits, in general, as per studies, can prevent weight gain as they have low energy density (2). Fruits also contain some amount of fiber that can, in a way, aid weight loss.
3. Helps During Pregnancy
Rambutan has several benefits during pregnancy. One reason – it is sweet. This helps improve dizziness or nauseating symptoms that are commonplace during pregnancy.
The fruit is a good source of iron as well. The mineral also helps fight fatigue and dizziness and improves hemoglobin levels. And since it is rich in vitamin E as well, it can be comforting in case one develops any itching.
4. Improves Heart Health
The high fiber content in rambutan can potentially reduce the risk of coronary heart disease (3). It also helps treat hypertension and might lower cholesterol levels – both of which can otherwise damage the heart.
5. Enhances Bone Health
The phosphorus in rambutan has a role to play here. The fruit contains good amounts of phosphorus, which aids in the formation of bones and their maintenance.
The vitamin C in rambutan also contributes to bone health.
6. Can Help Prevent Cancer
Rambutan is one of those fruits with a high antioxidant content, which is reason enough to say that it can prevent cancer. These antioxidants can fight inflammation and protect the cells in the body from getting affected.
The vitamin C in the fruit also aids in this regard. It neutralizes the harmful free radicals and offers protection against different forms of cancer.
According to one study, rambutan peels can alter and disturb the growth of cancer cells and can even be used for the treatment of liver cancer (4). And as per another report, eating five rambutans every day can drastically cut the risk of cancer (5).
7. Has Antibacterial And Antiseptic Properties
Studies suggest that rambutan has been used since the ancient times for its antibacterial properties (6). Certain studies also speak of the antiseptic properties of the fruit, which protect the body against numerous infections. The fruit accelerates wound healing and also prevents pus formation.
8. Boosts Energy
Rambutan contains both carbohydrates and protein, both of which can offer an energy boost when required. The natural sugars in the fruit also aid in this aspect.
9. Improves Digestive Health
The fiber in rambutan might help improve digestive health. It can aid digestion and also help prevent digestive issues like constipation. And the antibacterial properties might help kill intestinal parasites. Thus treating diarrhea as well.
However, we have less research in this regard. Please consult your doctor.
10. Works As An Aphrodisiac
Certain sources say that the leaves of rambutan work as an aphrodisiac. Simmering the leaves in water and then consuming them is said to activate the hormones that boost libido.
Rambutan is also believed to enhance fertility, though there is no research to back this up. Check with your doctor before using it for this purpose.
11. Promotes Scalp And Hair Health
The antibacterial properties of rambutan might treat dandruff and other scalp issues like itching. And the vitamin C in the fruit can nourish the hair and scalp.
The copper in rambutan treats hair loss. It also intensifies hair color and prevents premature graying.
Rambutan also contains protein, which can strengthen the hair roots. Vitamin C can also give your hair that added shine. You can simply apply rambutan juice to your hair and let it sit for about 15 minutes before shampooing as usual.
As there is little research in this aspect, we recommend you consult your doctor before you use rambutan for your scalp/hair health.
12. Enhances Skin Health
The seeds of the rambutan fruit are known to enhance your skin’s health and appearance. Mash the seeds into a paste and apply it to your skin for a clearer and even complexion. Using the seed paste regularly can soften and smoothen your skin and improve its texture.
Rambutan also hydrates your skin. The manganese in the fruit, along with the vitamin C, aids collagen production and also acts as an antioxidant that damages the free radicals. All of this keeps your skin healthy and young for a long time.
That’s pretty much the list of benefits. But there is a big question running around. Did you ever wonder if rambutan is the same as lychee? Let’s find out.
Rambutan Vs. Lychee – What’s The Difference?
Firstly, the two are different. Let’s accept that.
The rambutan is about the size of a golf ball. It has a red outer skin and yellowish green spikes all over. The flesh of this fruit is white and has a big seed at its center. It has a sweet, creamy, rich taste.
The skin is really thick and hard to peel.
The lychee is a little smaller than rambutan. It also has a red outer skin but minus the spikes. And the skin is rough. The flesh looks similar to that of the rambutan, but it tastes different. It is not as rich and creamy. It is crisper. And yes, this one also has a seed at the center.
The skin is not as thick, and you can peel it as you do with a hard boiled egg.
So, is that all? Is that all there is to rambutan? Well, no. There’s a host of other things you can do with the plant.
How Else Can You Use Rambutan?
We already saw how to use the fruit and its benefits. But that’s not it. There are other parts of the plant that are quite useful as well. These include the leaves, seeds, peel, and the bark. And here, we look at each of them.
- The Leaves
The leaves of the fruit contain healing juices. They possess analgesic properties, which basically means they act as an effective painkiller. It is said that drinking the juice works on your nerve centers and heals pain.
The juice from the leaves also offers great scalp health. You can also get rid of frizzy hair – just squeeze the juice from the leaves and apply to your scalp and hair. Rinse after an hour. Repeat 3 times in a week.
- The Seeds
The seeds also have numerous beneficial properties, but we suggest never to eat them raw. They contain saponins, compounds that can be extremely poisonous. Roasting or boiling the seeds seems to make them safer for consumption.
The seeds are full of proteins and carbs. Adding them to your snack can be a good idea. They also have oxidative properties, which can help remove blemishes from your skin. You just have to crush the seeds to make a fine paste and apply to your skin.
- The Peel
The peel contains flavonoids and gallic acid – these contain anti-cancer and anti-inflammatory properties. You can simply wash the peels and eat them raw. And don’t worry about the spines – they are just soft and tender.
The peel can also cure dysentery and fever. Just boil the peel and strain the liquid. Drink this twice or thrice a day.
- The Bark
The bark of the rambutan plant has astringent properties and can treat canker sores.
See? We told you. Not just the fruit, even the plant and its parts have some use. Now that’s cool, isn’t it? What’s even better are the facts about the fruit.
Any Fast Facts On Rambutan?
- The rambutan plant can reach as much as 66 feet in height.
- Rambutan produces fruit twice a year. And each plant/tree can produce as many as 6,000 fruits per season.
- The oil extracted from the seeds of rambutan can be used for cooking.
- There are over 200 varieties of rambutan today.
- Rambutan is usually harvested with more fruit left on the branches. This allows the fruit to stay fresh for longer and also makes it less prone to damage.
Rambutans might be those fruits you rarely come across. So if you want one, where can you get it? Good question.
Where To Buy Rambutans?
You can find rambutans in select stores, some of which include Kroger, Wegmans, Independent Asian Supermarkets, Walmart, Whole Foods Market, and 99 Ranch Market. Or you can also get the fruit online.
With rambutan, it’s a different story. Because this is a fruit that only ripens on the tree. One can’t prematurely harvest it. In the USA, the season is late June to August and again from December through January. The US crop primarily comes from Hawaii.
And in case you are heading to the market to buy your rambutans, there is a way to select the fruit. And then there is a way to store it.
What About The Selection And Storage?
While buying rambutans, look for the fresh ones that are bright red or yellow. The spines should be firm. Never choose a rambutan with bruises as it may be a sign of a damaged or overripe fruit.
It can be stored at room temperature for a couple of days. Refrigerating the fruits gives them a lifespan of a week or so, but they might lose their aroma. They should be ideally wrapped in a paper towel or a perforated plastic bag.
There are a few tips on how to cook this fruit. Basic guidelines, we can say.
Any Tips For Cooking?
- Before you even use rambutan for cooking, make a cut through the skin all the way round. Post which you can peel off the skin and use it.
- In case you are serving the fruit to your guests, you can retain half of the skin on the platter. This enhances the look of the fruit. Your guests can then peel the fruit and eat.
- Make sure you don’t cut the fruit half right through its seed.
And now for the million dollar question.
How To Eat Rambutan Properly?
We know it’s a tricky task, but we have you covered.
- The first step is to choose a ripe rambutan. A ripe rambutan is bright red with green spikes.
- Place the fruit on a cutting board, and using a kitchen knife, just cut through the tough rind. Don’t try to cut the fruit in half because, well, you can’t. There is a large seed at the center.
- Hold the knife stationary and slowly rotate the fruit. This will ensure some part of the ring is peeled off.
- Squeeze out one half of the rind with your fingers.
- You can either squeeze out the other half of the rind, or if you are worried about the loss of juice, just peel the rind.
- Ensure you dispose the seed before eating the fruit.
Okay. So now, you are relishing the fruit. You are happy. But wouldn’t it only get better if you add this fruit to some delicious recipe(s)?

We know the recipes are great. But we also must know the murky side of rambutan.
Does Rambutan Have Any Side Effects?
Most of the side effects come from the fact that the fruit is sweet.
Yes, we did speak of rambutan for its anti-diabetic properties. But there is another side to it. Rambutan contains fructose, and this can promote insulin resistance, worsening diabetes. It can cause a spike in the blood sugar levels.
In case you let the fruit ripen too much, the sugar in the fruit can turn into alcohol. And this can pose harm to people with blood pressure problems.
This is with the seeds. Eating them can be fatal. Hence, don’t eat them.
Peel it. Deseed it. Eat it. That’s all you need to know about rambutan.
