Key Differences

Capsaicin is an active component found in chili peppers that imparts the characteristic heat or spiciness when consumed. Capsicum, on the other hand, is the genus name for pepper plants, which includes a wide variety of peppers from sweet bell peppers to the intensely hot chili peppers.
The presence of capsaicin in capsicum fruits varies greatly; some capsicum varieties such as bell peppers contain negligible amounts of capsaicin, whereas others like habaneros and jalapeños contain higher levels, contributing to their spiciness.
Capsaicin is primarily concentrated in the inner membranes of fruits of the capsicum genus rather than the seeds or the outer fruit wall. This distribution plays a crucial role in the varying heat levels of different capsicum species and even individual fruits.
In terms of usage, capsaicin is extracted and used in various products such as topical ointments for pain relief, pepper sprays for self-defense, and culinary additives for heat. Conversely, capsicum fruits are used whole, either fresh, dried, or powdered, in culinary dishes worldwide to add flavor, heat, and nutritional value.
While capsaicin has been studied extensively for its potential health benefits, including pain relief and metabolic improvements, capsicum fruits also provide benefits such as high vitamin C content and other antioxidants, which vary among different capsicum species based on their capsaicin content and other phytochemical compositions.
