What Is Capsaicin And Why Is It So Effective?

If you suffer from ongoing sinus congestion, seasonal allergies, sinus headaches or migraines and you haven’t heard of capsaicin before, you might want to stop for a few minutes and read this through. (About a 15 minute read, but you won’t be disappointed.)

I think you’ll see very quickly why we developed our all natural homeopathic nasal spray Nasol around Capsaicin.

Believe it or not Capsaicin is an incredibly powerful compound for your body, either through food or supplemental use as it has a number of healing properties. 

It’s one of the world’s best natural stimulants and comes directly from the hot red chili pepper. 

If you eat chili peppers then you will already be getting a small dose of naturally occurring Capsaicin, however to really harness it’s true value, you’ll want to consider using it in an extract form as it becomes so much more powerful when used as an extract or as part of a blended product like Nasol.

When looking at all the advantages that Capsaicin can provide, it becomes quite clear that almost everyone can benefit from it in one way or another.

But in case you’re not familiar let’s look at some of these benefits so you can see and decide for yourself if it’s effective.

Nasal and Sinus Congestion

Nasal and sinus congestion is often common in people that suffer from rhinitis. Such people experience sneezing and postnasal drip. Patients who suffer from this type of congestion can greatly benefit from capsaicin.

In a research study involving 302 participants, this effect was evident. This study revealed that capsaicin reduced the symptoms of congestion in all the test subjects. 

Moreover, a dose of 4 micrograms per puff was effective enough to produce this effect. People who continued to use this dose reported an overall reduction in sneezing and nasal and sinus blockage within four weeks. 

Another study was also conducted to study the same effects.  In this study, forty-two people participated in the study. The study was dependent on the improvement of the total nasal symptom score. All patients reported improvement in these scores. Due to the reason that they had less nasal congestion, sinus pain, sinus pressure, and headache. 

There’s quite a compelling amount of evidence on how effective capsicum is for treating sinus related conditions, in fact even more today then when we first decided to make Nasol all those years ago...but given that it had immediately helped us there wasn’t many more compelling reasons to Capsaicin’s effectiveness than when we had experienced first hand.

In addition to treating sinus and other nasal conditions Capsaicin can have a positive impact on a variety of ailments, continuing with those treated through nasal administration such as sinus headaches, migraines and allergies Capsicum supplementation in other forms has also shown promise in a variety of other situations.


Various allergies are due to inflammatory responses in the body. Capsaicin has a strong effect on these inflammation-causing cells. This is one of the reasons that Capsaicin is effective in allergic rhinitis. It is a type of rhinitis triggers due to changes in environmental conditions AKA seasonal allergies.

Nasol has become very popular during the change of seasons as it’s nasal administration has been the perfect way to utilize Capsaicin for treating the main symptoms many experience with allergies. 

Another study shows that capsaicin is also helpful in treating skin allergies. As discussed above, it decreases the effect of substance P on nerves. With the help of Capsaicin, a reduction in flare formation occurs in skin allergies. What this means is that Capsaicin is helpful as a pretreatment substance in skin allergies when ingested regularly or applied as part of a topical preparation.

Headaches  and Migraines

If you’re someone who’s often impacted by sinus and allergy related headaches, you’re probably looking for fast relief. The great news is that Capsaicin is one of the best natural treatment methods3 for migraines available and won’t leave you with those unwanted side effects like most other medications do; such as that feeling of groggy and being out of it. 

Capsaicin will help to open up the nasal passages, helping you breathe easier while also helping to desensitize the mucous membranes in the nose so they aren’t as irritated when airborne particles pass through. 

Using Capsaicin in a spray for these ailments is your best defense as it’ll get right to the source quickly and effectively. 

Different types of migraines such as cluster migraines and chronic migraines can also benefit from Capsaicin treatment as per referenced studies below. 

The effect of Capsaicin as a migraine reliever is so powerful that you can benefit from it in just one application. This effect was marked as “evident” in a study consisting of twenty-three participants. The patients applied Capsaicin gel on their scalp arteries. All participants reported a reduction in 50% of the pain symptoms. Although a small scale study, just one of many reporting the benefits of capsaicin in this regard.

Arthritis and Inflammation

Capsaicin supplementation can help to lower inflammation in the body. For some this may help to relieve inflammation from those who are suffering from pain, that comes from high levels of inflammation in the bones and joints like Arthritis.

Osteoarthritis is a very common disease that affects the joints. The typical treatment for this disorder is acetaminophen which of couse with prolonged use can have terrible side effects. Capsaicin may also beneficial for this condition. Literature reviews between 2004 and 2016 show that topical capsaicin is very effective. In comparison to acetaminophen, it is also very safe.

Help With Gastric And Digestive Disorders 

Inflammation is also a leading contributor to other major diseases as well such as heart disease and diabetes, so the better you can get inflammation under control, the better management you’ll have with these conditions. 

While you may think that something that’s so spicy would only irritate the stomach, this is surprisingly not the case. Capsicum has been used by many to help prevent peptic ulcers from developing as it can help to increase the production of gastric mucus, which then helps to provide an extra layer of protection for the gastric lining. 

It may also be used to help treat and better manage diarrhea as well and has been shown to help those who are suffering from Crohn’s disease, an inflammatory disease of the bowels. 

Cancer Prevention 

Cancer is a devastating disease and claims the lives of many people worldwide, so is something that you definitely want to put forth effort to prevent.

Eating a diet rich in fresh fruits and vegetables is one step in the right direction, but beyond that, also consider utilizing capsaicin. Research1 has shown that it may help to actually alter the gene expression and prevent the cancer cells from surviving and prevent metastasis. 

While research is still early in development on all the potential effects capsaicin can provide in this area, it does look promising. 

Enhanced Heart Health

Capsicum may help to lower your risk for coronary heart disease by helping to create a vasodilation effect in the body, which improves blood flow to and from the heart2

One of the leading causes of death in today’s society, partly due to the sedentary lifestyles we’ve adopted and the diets we are currently eating, taking measures to prevent it are essential. 

Along with vasodilation the effect of Capsaicin then also helps the blood become more oxygen rich, which then means the organs get the nutrition they need to function optimally. 

Potential Weight Loss Aid 

A benefit that catches the attention of many is the fact that capsaicin can also serve to provide excellent weight loss benefits as well. 

Because it acts upon the central nervous system to provide mild stimulation, which then speeds up your metabolic rate for a few hours after consuming it.

Your metabolic rate is the biggest determinant of your total daily expenditure and your total daily expenditure along with your food intake dictates whether you gain or lose weight.

Anything that boosts your expenditure means faster weight loss assuming you maintain the same total calorie balance. 

Some people also note that capsaicin has appetite reducing properties as well, so you might just find it helps you stick with your diet better, maintaining your target calorie intake. 

Enhanced Immune System Strength 

Capsaicin also contains a powerful dose of vitamin C, which is well known for its ability to boost your immune system and keep you free from illness.

Antioxidant Benefits 

One final unique thing about capsaicin is it’s an antioxidant source that also helps with vasodilation, so by increasing the diameter of the blood vessels and speeding blood flow through the body, this will actually help to transport the antioxidants to the tissues faster making them even more powerful.

Side Effects of Capsaicin

Capsaicin is a relatively safe compound. People rarely report any side effects after using it. However, certain side effects can occur after topical application of the compound. These side effects are usually easily tolerable. Some of these include

  • Burning 
  • Itching
  • Redness
  • Swelling

All of the side effects occur for a short period. You will experience fewer side effects after continuous use. 


I’m sure it’s now easy to see why we believe so much in Nasol (even though that first spray can be a little uncomfortable) as you can see capsaicin is a powerful extract in a variety of forms with many powerful health benefits.  No matter what health problem you are dealing with, there’s a good chance that capsaicin might be able to help.
