What Is Cayenne Pepper?

It is a moderately hot chili pepper that is used to flavor dishes. It is generally skinny and red, 10 to 25 cm long, and has a curved tip. Also known as chili peppers, African pepper, capsicum fruit,
pimienta de cayena (in Spanish), and zanzibar pepper, cayenne pepper is a cultivar of Capsicum annuum (which is related jalapenos, bell peppers, and paprika).

Cayenne pepper contains a high amount of capsaicin (more of which we will talk about in a while) that is responsible for most of its benefits. Capsaicin is also responsible for the fruit’s fiery hot flavor. The pepper is rated between 30,000-50,000 on the Scoville heat units (a measurement scale for the ‘hotness’ of a chili pepper). And let us tell you that the rating is too damn high.

Now, let’s get to the history.

What Is The History Of Cayenne Pepper?

Cayenne pepper gets its name from the city of Cayenne in French Guiana. It is known to have originated in Central and South Americas, and was initially used as decoration – and this was much before people realized its importance as a culinary spice and medicine.

Christopher Columbus had discovered these fruits while traveling across the Caribbean. He brought them back to Europe as a substitute for black pepper (which was expensive back then). And today, cayenne pepper is cultivated across the world.

All good. But is it that good?

Capsaicin, and capsaicin only. Okay, at least most of the time. This compound in cayenne pepper that renders it its hot and spicy flavor is responsible for all that is good and glorious about cayenne pepper.

And then, there are other nutrients like vitamins A and C, which contribute to most of the ways this spice can do good to you.

The benefits of cayenne pepper are as decorated as its history. But before we get there, let’s check out what this spice is made of.

What Are The Benefits Of Cayenne Pepper?

The Capsaicin in cayenne pepper offers varied benefits. It boosts metabolism and heart health, and even clears congestion. Cayenne pepper is also known to relieve joint pains and other inflammatory conditions. The spice does good to skin and hair as well.

1. Boosts Metabolism

It’s all about metabolism, isn’t it? Studies show that cayenne pepper can boost metabolism and even suppress hunger (1). And for this, we must thank capsaicin (which is also called a thermogenic chemical). This compound is known to produce extra heat in our bodies and burn more fat and calories in the process. Research tells us that taking foods rich in capsaicin can increase our body’s metabolic rate by 20 percent (for up to 2 hours) (2).

A 2014 study found that people who took red peppers with every meal experienced fewer cravings and an enhanced feeling of fullness (3). This means that adding capsaicin to your diet can suppress your appetite. And this means cayenne pepper can help you in your weight loss mission too (4). Yay!

But hold on – we are only saying that adding cayenne pepper to your diet helps in certain ways. Please don’t torture yourself by filling your plate only with cayenne pepper!

2. Improves Digestive Health

2. Improves Digestive Health


It is said that the quality of your health depends on the quality of your digestive function. And with cayenne pepper, the latter (and the former) can definitely be taken care of.

Cayenne has the uncanny ability to boost heart action and circulation – thereby accelerating the digestive process. It also improves the stomach’s ability to defend infections and increase the production of digestive fluid. The pepper also smoothens the way important enzymes are delivered to the stomach (5). All of this enhances your digestive health.

Now, allow us to bust some myths. Capsaicin in cayenne pepper can help heal stomach ulcers. Of course, excessive consumption of spicy foods can sure lead to ulcers. But capsaicin is not the one to be blamed (6).

The pepper can also heal intestinal gas, stomach pain, diarrhea, and an upset stomach as well.

3. Might Lower Blood Pressure

Some sources say that the capsaicin in cayenne pepper can lower your blood pressure overnight. Literally. Well, that might seem a little far-fetched (we don’t know, though), but what is true is that cayenne pepper can sure help heal your blood pressure woes.

The pepper opens up blood vessels, and this increases blood flow. As the rate of blood flowing through your system increases, your blood pressure naturally comes down (7).

Capsaicin also affects the sensory nerves that work with neuro-hormonal systems, and this lowers blood pressure. But then, cayenne pepper is not a replacement for your blood pressure medication. It is just a supplementation.

Simply mix one teaspoon of cayenne pepper with half a glass of lukewarm water and drink at night before bed.

4. Can Reduce Pain

Cayenne for pain – yes, that’s what we are talking about.

According to the University of Maryland Medical Center, capsaicin can reduce pain. The compound has powerful pain-relieving properties and works amazingly well when applied to the pain area. Here’s the science behind it – capsaicin reduces the amount of substance P (a chemical that delivers pain messages to the brain). As a result, you feel relief (8). This is why even most pain ointments have capsaicin as one of their ingredients.

Applying capsaicin to the skin also makes the brain respond by releasing dopamine, the feel-good hormone that offers a sense of reward and pleasure (9).

Cayenne works well for migraines too. Consuming it orally also reduces substance P and stops pain transmission. More importantly, it reduces platelet aggregation factor, also called PAF, which is what leads to migraines (by constricting the blood circulation in your head).

The pepper has a use for treating cramps as well. Capsaicin can reset the nerve-to-muscle communication by shocking the system into place. This can help relieve cramps. And some sources say that cayenne can relieve nerve pain – though we don’t have adequate research on this.

5. Can Prevent Cancer

In several studies, capsaicin has demonstrated the ability to induce apoptosis (death of cancer cells). In fact, it also arrests the ability of cancer cells to travel across the body.

One study talks about how capsaicin can help manage prostate cancer (10). And another American study talks about the anti-tumor activity of capsaicin. The compound can be beneficial in treating cancers of the lung, breast, colon, and prostate (11).

6. Protects The Heart

Given that cayenne improves the health of blood vessels and lowers blood pressure, it sure does good to the heart.

Cayenne pepper also prevents blood clots, making it effective in preventing heart attacks. The capsaicin clears the lipid deposits that narrow the arteries.

Studies show that cayenne is also effective in treating blood circulation problems, cardiac arrhythmia (irregular heartbeat), and palpitations.

As unbelievable as it might sound, one report suggests that cayenne pepper can stop a heart attack in just 30 seconds. In fact, the famed natural herbalist Dr. John Christopher is known to bring his patients out of heart attacks just by making them drink warm cayenne water (12).

Cayenne pepper is also beneficial in preventing heart disease associated with diabetes. And more interestingly, cayenne can help reduce plaques (and might lower cholesterol). It breaks down the fibrin networks that hold the plaque in place, thereby reducing the build-up.

7. Clears Congestion

7. Clears Congestion


If you are suffering from a sinus congestion, cayenne pepper can help you out. The capsaicin in the pepper can thin the mucus and stimulate the sinuses. This ultimately aids air circulation, offering you relief. Taking foods containing cayenne pepper can help clear your congestion (13).

Capsaicin might also have a beneficial effect on rhinitis, a disease with symptoms like postnasal drip and nasal congestion. Though we still require more studies, the future looks promising in this regard (14).

One of the best ways to use capsaicin is to get the related nasal spray from your nearest pharmacy. You might also take cayenne orally. You can add one teaspoon of the pepper to a cup of hot water and take it thrice a day. This dilates the blood vessels in your nose, stimulates secretions, and drains the sinuses.

Cayenne pepper can also help clear congestion caused by bronchitis. It helps treat sinus infections, sore throats, and laryngitis as well (you can use it as a gargle) (15). It might even help treat cold and flu and other related allergies.

8. Helps Detoxify

Detoxifying is like recharging your batteries for a new and invigorated you. And you can very well take the help of cayenne in this process.

One of the more popular detox diets consists of cayenne pepper and lemon. This diet was developed way back in 1940 by Stanley Burroughs, an alternative health practitioner. This diet works by lowering the calorie intake.

The detox diet lasts for 10 days, where you need to drink 12 glasses of a tonic that consists of water, lemon juice, maple syrup, and cayenne pepper. And by the way, no solid foods. You should be getting around 650 to 1,300 calories a day. Here, the weight loss happens very quickly, and you might lose close to 3 pounds a week. Most of that weight is water weight, though.

However, we don’t really recommend you follow this detox diet. Because we humans need a variety of nutrients to stay healthy, and this detox diet doesn’t offer you much. Though certain anecdotal reports suggest that this diet leaves one feeling healthier and energetic, there is no concrete research. In fact, your body’s natural detoxification system is enough to keep you healthy. This detox tonic can probably be a healthy alternative to sugary beverages, once in a while.

Or best, simply add cayenne pepper to your foods to aid detoxification.

9. Relieves Joint Pains

We already saw the pain-relieving effects of capsaicin. Studies have revealed that applying creams containing capsaicin on painful joints improved their condition.

As per the Arthritis Foundation, capsaicin (which also is one of the capsaicinoids present in cayenne pepper) has anti-inflammatory properties that can help relieve arthritis and joint pains (16). Topical capsaicin can also be effective for osteoarthritis pain and fibromyalgia (17).

10. Has Antimicrobial Properties

Cayenne pepper can prevent infection in the case of an injury, thanks to its antibacterial properties. It also possesses antifungal properties.

11. Improves Immunity

Though there are not many studies on this, the antioxidants in cayenne pepper can enhance one’s immunity. Eating the pepper also increases your body heat, and this is said to strengthen your immune system as well.

12. Can Heal Toothaches

Using cayenne pepper for toothache is an old-fashioned remedy, but one that works. The pepper acts as a counter-irritant and decreases the deeper tooth pain. It also increases local blood flow.

13. Improves Skin And Hair Health

13. Improves Skin And Hair Health


Though we have less research on this, some reports promote the benefits of cayenne pepper for one’s skin and hair. The capsaicin in the pepper can soothe skin redness (its anti-inflammatory properties) and also treats acne-induced skin discoloration. But don’t use the pepper alone. Mix one spoon of the pepper with some cocoa powder and half a ripe avocado till you get a paste. Apply it to your face and rinse after 15 minutes.

The vitamin in cayenne pepper can improve hair health too. Mix some of the pepper with honey and apply to your scalp. Cover your hair with a cellophane cover. Wash after 30 minutes.

You can also add three eggs and olive oil to this mixture and follow the same procedure for stronger hair. This remedy can also add volume and shine to your hair.

We are done with the benefits. You definitely would want to pick a few peppers now, wouldn’t you? But how do you do that? And where do you store them?

Frequently Asked Questions

Can I use capsaicin for my eyes?

You can put a little bit (in case the skin around your eyes has inflamed as cayenne pepper has anti-inflammatory properties), but your eyes would burn very badly. Hence, we suggest you don’t.

Does taking cayenne pepper make you smell of garlic?


Is there a substitute for cayenne pepper?

If cayenne pepper feels too spicy, you can go with capsicum. It also contains capsaicin.

I have started taking cayenne pepper for blood pressure, but it has actually increased. Why does this happen?

That is a common experience. And this is what Dr. John Christopher has to say about this: “This herb is a great food for the circulatory system in that it feeds the necessary elements into the cell structure of the arteries, veins and capillaries so that these regain the elasticity of youth again and the blood pressure adjusts itself to normal. When the venous structure becomes loaded with sticky mucus, the blood has a harder time circulating; therefore, higher pressure forces the liquid through. Cayenne regulates the flow of blood from the head to the feet so that it is equalized; it influences the heart immediately, then gradually extends its effects to the arteries, capillaries, and nerves.”
