Cayenne pepper is a hot chili in the Capsicum family. People frequently use it to enhance the flavor of savory dishes, and nutrients in the pepper may provide health benefits.
Cayenne peppers are closely related to jalapeño and bell peppers. They are a staple in Southwestern American, Mexican, Cajun, and Creole cuisine. Dried and ground, they make a powdered spice for seasoning and also feature whole in Korean, Sichuan, and other Asian cuisines.
Meanwhile, practitioners of traditional Chinese and Ayurvedic medicines use cayenne pepper in several ways, including to help treat circulatory problems.
The spiciness comes from the pepper’s active ingredient, capsaicin, which is present in many topical preparations for aches and pains in muscles and joints.
In this article, we describe the nutritional contents of cayenne pepper. We also explore possible health benefits, how to incorporate more into the diet, and associated risks.
Cayenne pepper may have a range of health benefits, and people may experience these by using preparations that contain capsaicin or by eating the peppers.

Boosting antioxidant activity
The antioxidants in cayenne pepper include:
- vitamin C, which also supports the immune system

To make a home remedy that includes cayenne pepper, a person could try the following:
- Combine 1/4 teaspoon (tsp) of cayenne pepper, 1/4 tsp of ground ginger, 1 tablespoon (tbsp) of honey, 1 tbsp of apple cider vinegar, and 2 tbsp of water, then taking the mixture by the teaspoon.
- Mix cayenne pepper and apple cider vinegar into hot water, making a tea, to clear the sinuses.
However, there is a lack of scientific evidence to suggest that these home remedies are effective.
Capsaicin, the active ingredient in cayenne peppers, may have pain-relieving properties.
One review published in 2016 looked at the potential for capsaicin in a cream to reduce pain. The authors concluded that there may be benefits to long-term use.

However, some people who try this treatment experience an unpleasant burning sensation as a side effect.
Other research has suggested that taking oral capsaicin supplements may help relieve pain and discomfort in athletes. However, scientists are still investigating how this might work and what dosage might be effective.
There are also concerns that it may cause gastrointestinal distress in some people.

Cayenne is a versatile spice that goes well with savory dishes. Some people add it to egg or fish dishes, casseroles, tacos, or pasta.

Cayenne pepper contains capsaicin, a compound that gives it its hot taste. Capsaicin may benefit the body in various ways.
However, the evidence for this has come from studies that tested the compound in creams and supplements — adding cayenne pepper to the diet may not have the same positive effects.
Still, many people enjoy the kick that cayenne pepper adds to savory foods, and the antioxidants in the pepper may help protect the body from a range of diseases.
Is cayenne pepper safe for children to eat?
When it’s appropriate to begin offering a variety of foods to children, it’s important to give the child what the family normally consumes.
If cayenne pepper is a typical ingredient for your family, start by adding only small amounts to a child’s diet, since a child’s pain receptors are more sensitive.
Cayenne pepper can be perfectly safe and healthful for children to consume if it is introduced slowly, but watch carefully for any aversions, sensitivities, intolerances, and other reactions.
