Cayenne pepper popularly known as “shombo” in Nigeria is a common spice  found in fresh, fried and powdered forms used for culinary purposes, but unknown to many, it is a great herbal remedy and it has the power to treat illnesses and boosts overall health.

For years, Cayenne pepper has been used both as food and medicine. They are delicious spicy chilli peppers that are packed with medicinal properties, vitamins and minerals.

Cayenne peppers have several health benefits including

1. Digestive health 

Cayenne pepper aids the digestive system to work efficiently by inhibiting enzyme production. Researchers have proven that capsaicin stimulates alkali and mucous secretions, preventing and curing gastric ulcers. They also relieve gastrointestinal issues like bloating and gas. 

Research in the “Journal of Physiology and Pharmacology” indicates that capsaicin, found in cayenne pepper, boosts gastric mucosal blood flow and strengthens mucosal defenses, guarding against gastric ulcers.

Additionally, a study in the “European Journal of Pharmacology” suggests that capsaicin may suppress stomach acid secretion, offering potential relief from gastrointestinal issues such as bloating and gas.

2. Weight loss

Cayenne pepper is a metabolism booster and promotes fat burning. This means that regular intake in small amounts helps to burn more calories. It also eases inflammation from allergies. 


Clinical trials highlighted in the “British Journal of Nutrition” demonstrate that supplementing with capsaicin leads to heightened energy expenditure and enhanced fat oxidation, thereby aiding in weight loss and promoting metabolic well-being.

Furthermore, a meta-analysis published in “Critical Reviews in Food Science and Nutrition” concludes that consuming capsaicin reduces appetite and increases feelings of fullness, underscoring its effectiveness in managing weight.

3. Heart Health 

Cayenne may help prevent myocardial infarction (heart attacks) by promoting blood flowing effectively through the circulatory system, reducing blood pressure and improving circulation. It has a mild blood-thinning action, which may be helpful in people with cholesterol problems. 

A study featured in “Critical Reviews in Food Science and Nutrition” indicates that capsaicin displays vasodilatory properties, enhancing blood circulation and potentially mitigating the risk of cardiovascular ailments like myocardial infarction.

Moreover, clinical trials, such as the one published in “Nutrients,” propose that incorporating capsaicin-rich foods into one’s diet could contribute to lowering blood pressure through the promotion of endothelial function and reduction of vascular resistance.

4. Anti inflammatory properties 

They contain antioxidants that combat inflammation and reduce the risk of chronic diseases. Cayenne pepper contains vitamin A  which helps in maintaining good health, healthy skin, and proper brain function and Vitamin E  which is another super antioxidant that slows the aging process and keeps bodily organs healthy. 

Research in “Molecular Nutrition & Food Research” highlights capsaicin’s anti-inflammatory properties, potentially mitigating chronic inflammation and related disease risks.

Additionally, the “Journal of Agricultural and Food Chemistry” reports cayenne pepper’s abundance of antioxidants like carotenoids and flavonoids, crucial for combating oxidative stress and inflammation, promoting overall health.

5. Pain relief 

Due to capsaicin, they can alleviate pain, including arthritis and nerve pain. Cayenne powder applied locally reduces the amount of substance P, a chemical that sends pain signals to the brain. Reduction or removal of this chemical stops pain signals from reaching the brain and relieves pain.

Clinical trials, including one featured in “Pain Medicine,” confirm the effectiveness of topical capsaicin formulations in alleviating pain linked to conditions such as arthritis and neuropathy. Capsaicin functions by depleting substance P, a neurotransmitter implicated in pain perception, as supported by findings in “Current Pharmaceutical Design.”

6. Boosts immunity and prevents allergies 

The high vitamin C content in cayenne peppers can support immune function. High doses of beta carotene, antioxidants, and anti-inflammatory capabilities in cayenne pepper can prevent allergies and improve overall health. 


Studies, including one in “Nutrients,” emphasize capsaicin’s immune-modulating effects, potentially boosting immune function and lowering the risk of allergic reactions. Moreover, research in “Food Chemistry” indicates that cayenne pepper’s abundant vitamin C content enhances its immunomodulatory properties, promoting overall health and allergy prevention.

7. May lower blood pressure 

A diet containing capsaicin (the active ingredient in cayenne pepper) helps relax blood vessels in a way that leads to lowered blood pressure, Studies show eating foods that contain capsaicin, such as cayenne peppers, can have a positive impact on blood vessels, and subsequently, blood pressure.

Clinical trials, exemplified by a study in “Hypertension,” demonstrate that capsaicin supplementation results in notable reductions in both systolic and diastolic blood pressure. These findings suggest the potential of capsaicin as a supplementary therapy for managing hypertension.

8. Prevents cancer 

Some studies have reported that cayenne pepper may help the body cells fight many types of cancer, including prostate, melanoma, and pancreatic cancer. This study however still needs more evidence. 


Preliminary studies suggest promising results regarding cayenne pepper’s potential anticancer properties; however, further research is necessary to establish conclusive evidence. For example, a review in “Cancer Research” proposes that capsaicin might inhibit the growth of different cancer cell lines.

Cayenne pepper can be sprinkled on dishes, added to soups, or mixed into sauces for a spicy kick. It should be known that moderation is key as excessive consumption can cause irritation or digestive issues. Always consult with a healthcare professional for personalized advice.
