Botanical Overview
Bell Pepper (Capsicum annuum) is a flowering plant in the Solanaceae family. This plant has earned a place in traditional medicine through its consistent therapeutic benefits, recorded across multiple cultures. The nightshade family (Solanaceae) includes herbs, shrubs, and small trees with alternate leaves and star-shaped or trumpet-shaped flowers. The fruits are typically berries or capsules. Many species produce potent alkaloids including tropanes, solanines, and nicotine, making this family both medicinally valuable and potentially toxic.

General Description
The plant produces berries of many colors including red, green, and yellow, often with pungent taste. It is one of the oldest cultivated crops, with domestication dating back to around 6,000 years ago in regions of Mexico. The genus Capsicum has over 30 species but Capsicum annuum is the primary species in its genus, as it has been widely cultivated for human consumption for a substantial amount of time and has spread across the world. This species has many uses in culinary, medicine, self-defense, and ornamental applications.

Traditional Uses
Bell Pepper has been traditionally used for digestive health, respiratory conditions, and skin and wound care, among other applications.
Digestive health.
- Dyspepsia
- Stomachic
- Carminative
For digestive complaints, the herb is typically prepared as a tea or decoction taken before meals. The bitter compounds stimulate digestive secretions and improve nutrient absorption. Some traditions use the powdered root or leaves in small doses as a stomachic tonic.
Respiratory conditions.

Respiratory conditions are addressed through steam inhalation of the herb’s vapors or internal use as a warm tea. The hot infusion acts as an expectorant, helping to loosen phlegm and clear congestion. Some traditions combine it with honey for coughs.
Skin and wound care.
- Sore
- Skin
For skin conditions, the fresh or dried plant is applied topically as a poultice, wash, or compress. A strong decoction can be used to clean wounds and sores. The antimicrobial properties help prevent infection while promoting tissue repair.
