Botanical Overview
Commonly known as Basil, this species belongs to the Lamiaceae family. Traditional healers across continents have independently recognized the medicinal value of this species, leading to one of the most extensive ethnobotanical records available. The mint family (Lamiaceae) includes aromatic herbs and shrubs with square stems, opposite leaves, and two-lipped flowers. Many species produce essential oils in glandular trichomes on their leaves and stems. This family is one of the most important sources of culinary and medicinal herbs worldwide.

Traditional Uses
Basil has been traditionally used for digestive health, respiratory conditions, and skin and wound care, among other applications.
Digestive health.
- Carminative

Skin and wound care.
- Sore
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.
