Capsaicin is the natural compound that makes cayenne pepper hot. It concentrates in the white pith and membranes around the seeds, and it triggers a warming sensation in the mouth. Cayenne Pepper Fruit Extract is one of eight highlighted ingredients in Glyco Barrier drops.
The pepper and its famous compound
Cayenne is a variety of Capsicum annuum, a species that also includes bell peppers, jalapenos and paprika types. Its long, slender, bright red pods are usually dried and ground into the red powder sitting in many spice racks.
The heat comes from a family of compounds called capsaicinoids, led by capsaicin. Plants make it in glands on the inner tissue of the fruit, and it is odorless and colorless on its own.
Where the heat really lives
Many cooks assume the seeds are the hottest part. In truth, capsaicin concentrates in the white pith, the spongy membrane that holds the seeds to the pod. The seeds pick up heat simply by touching it.
That is a handy kitchen trick. If you want a milder dish, scrape out the pith along with the seeds. If you want more fire, leave them in or even add extra pith.
Why your mouth feels warm
Capsaicin does not burn the way a hot pan does. Instead it activates a receptor on nerve endings called TRPV1, the same receptor that registers real heat. Your brain gets a warmth signal, even though the temperature has not changed.
Birds lack the same sensitivity, which is why wild chili plants can spread their seeds through bird droppings while discouraging many mammals. It is a neat bit of plant strategy.
Cayenne in everyday cooking
Cayenne is a workhorse in kitchens around the world, from Cajun seasoning blends to Indian curries, Mexican hot sauces and Southern fried chicken. A pinch goes a long way, so cooks usually start small.
- Eggs. A dash on scrambled eggs wakes up breakfast.
- Roasted vegetables. Toss sweet potatoes or cauliflower with oil and a little cayenne.
- Soups and beans. Stir in a pinch near the end of cooking.
- Hot chocolate. A traditional pairing in Mesoamerican drinks.
A short history of the pepper
Peppers originated in the Americas, and people there were cultivating them thousands of years ago. After European voyages, chilies traveled to Africa, India and Asia, where cooks embraced them so enthusiastically that many people now picture them as native to those cuisines.
The name cayenne is often linked to the city of Cayenne in French Guiana. Whatever its exact route, the pepper has become a pantry staple on nearly every continent.
Handling and storing cayenne
Capsaicin clings to skin, so wash your hands after chopping fresh peppers and keep them away from your eyes. Powder should live in a tightly sealed jar away from light and heat, where it keeps its color and punch for months.
Fresh pods can be strung up to dry, or frozen whole and grated straight into dishes. Pairing cayenne with citrus, tomato, garlic or sweet potato is a reliable way to keep a pinch balanced. For more spice ideas, explore our guide to everyday spices for flavorful meals.

Building spice tolerance gradually
Heat preference is partly learned. People who eat spicy food regularly tend to enjoy higher levels over time, and a gentle approach works for everyone else.
- Start small. Try one eighth of a teaspoon in a pot of chili.
- Pair with fat. Avocado, cheese or olive oil rounds out the burn.
- Add late. Stir cayenne in near the end so you can taste and adjust.
Fitting it into your day
The brand's directions are simple: 1 mL, about two droppers, in the morning and again in the evening, with or without food. Many people anchor each serving to a moment they already have, like brushing teeth or pouring coffee.

Capsaicin is the star of the pepper, hiding in the pith and speaking to your nerves rather than your thermometer. Knowing that makes you a better cook and a sharper label reader.
