Morphological Description

Ximenia americana, commonly known as Wild Plum or Yellow Plum, is a small tree or shrub growing 2–7 m tall, with a trunk diameter up to 10 cm. It is characterized by:

·       Bark: Dark brown to pale gray, rough, often peeling in thin strips

·       Branches: Spiny, zigzag, with short, stiff thorns up to 2 cm long

·       Leaves: Alternate, elliptic to ovate, 3–6 cm long, 1–3 cm wide, leathery, glossy green

·       Flowers: Small, fragrant, white to greenish-yellow, 5–8 mm long, in clusters, blooming year-round in tropics

·       Fruit: Drupe, 2–3 cm in diameter, green turning yellow to orange when ripe, with a tart-sweet flavor

Its semi-parasitic roots attach to nearby plants, aiding nutrient uptake.

Distribution and Habitat

Ximenia americana is pantropical, found across Africa (e.g., Nigeria, Kenya, South Africa), the Americas (e.g., Brazil, Florida), Asia (e.g., India, Thailand), and Australia. It thrives in:

·       Habitats: Savannas, woodlands, dry forests, coastal dunes, scrublands

·       Climate: Tropical and subtropical, with rainfall of 500–1,500 mm annually, temperatures of 20–38°C

·       Soil Conditions: Well-drained sandy or loamy soils (pH 5.5–7.5), often in arid zones

·       Elevation: Sea level to 2,000 m

Its resilience makes it a pioneer species in disturbed areas.

Ethnopharmacology

Ximenia americana, commonly known as wild plum or yellow plum, is a medicinal plant extensively used in traditional medicine across Africa, Asia, and tropical America. Various parts of the plant, especially the leaves, roots, bark, seeds, and fruits are employed for their wide range of therapeutic properties. It is traditionally used to treat skin infections, wounds, diarrhea, fevers, malaria, muscle pain, and respiratory ailments. The plant exhibits antimicrobial, anti-inflammatory, analgesic, antioxidant, antimalarial, and astringent effects. The root and bark are commonly used as topical applications for skin conditions and ulcers, while the leaves and fruits are often taken as decoctions to address internal infections and digestive issues. Phytochemical analyses have identified active constituents such as flavonoids, saponins, tannins, alkaloids, and fatty acids, which contribute to its medicinal value. Despite its broad traditional use, more scientific and clinical studies are needed to validate its pharmacological effects and ensure safe dosage guidelines.

·       Antimicrobial: Leaf extracts inhibit *Escherichia coli* and *Candida albicans*, used in Mali for infections.

·       Antioxidant: Fruit polyphenols neutralize free radicals, used in Tanzania for oxidative stress.

·       Gastrointestinal Treatment: Root decoctions treat diarrhea in Nigeria, with tannins aiding gut health.

·       Skin Conditions: Seed oil heals ulcers in South Africa, with fatty acids promoting regeneration.

·       Antimalarial and Antipyretic: Bark extracts lower fever in Ethiopia, showing activity against *Plasmodium* species.

⚠ Toxicity Profile: No acute toxicity at traditional doses, but seeds contain cyanogenic glycosides (e.g., hydrocyanic acid), potentially releasing cyanide if ingested raw in excess. Fruits are safe in moderation but may cause nausea if overconsumed. Use under guidance is advised.

Phytochemistry

The plant’s medicinal properties stem from a rich phytochemical profile:

·       Fatty Acids: Linolenic, linoleic, oleic, and stearic acids in seeds, with antimicrobial and emollient effects

·       Flavonoids: Quercetin and kaempferol, providing antioxidant benefits

·       Tannins: Astringent compounds aiding wound healing

·       Terpenoids: Anti-inflammatory and analgesic agents

·       Phenolics: Gallic acid, supporting antimalarial properties

·       Alkaloids: Contribute to antimicrobial actions

The fruit is notably high in vitamin C, enhancing its nutritional value.

Additional Uses

·       Nutritional: Fruits eaten raw, dried, or as juice in Senegal, rich in vitamin C and potassium

·       Cosmetic: Seed oil used in Brazil for hair conditioning and skin moisturizing

·       Economic: Wood crafted into tools and fuel in Kenya

·       Ethnoveterinary: Leaves treat livestock wounds in Namibia
