Botanical Overview
Commonly known as Indian Mulberry, this species belongs to the Rubiaceae 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 coffee family (Rubiaceae) includes trees, shrubs, and herbs with opposite leaves and interpetiolar stipules. The flowers are typically tubular with four or five petals. The family includes coffee (Coffea), quinine-producing Cinchona, and numerous other medicinal species with alkaloid constituents.
General Description
It is commonly known as noni or Indian mulberry, among many other names. Native to Southeast Asia and Australasia, the species was spread across the Pacific by Polynesian sailors. It is now cultivated throughout the tropics and is widely naturalised. The plant contains anthraquinones, which can be harmful to human health. Although the fresh fruit is edible, its pungent odour makes it worthwhile only as a famine food. It is also used in traditional medicine and processed into products such as juices.

Traditional Uses
Indian Mulberry has been traditionally used for digestive health, respiratory conditions, and skin and wound care, among other applications.
Digestive health.
- Diarrhea
- Laxative
- Colic
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.
- Cough
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.
- Wound
- Boil
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.
