It is widespread in the tropical rainforest of West African countries, such as Nigeria, Côte d’Ivoire, Sierra Leone, Ghana and Senegal. It is called utazi by the Ibos, arokeke by the Yorubas and urasi by the Efiks and the Ibibios.

This class of medicinal plants is beneficial in preventing and treating certain diseases and ailments that are detrimental to human health. The leaves, which can be chewed, infused or used for cooking, are mainly used in the Western part of Africa for nutritional and medicinal reasons.

Characteristics and constituents

Utazi has a characteristic sharp, bitter and slightly sweet taste, especially when eaten fresh. It contains essential oils, glycoside, alkaloids, saponins and tannin, various minerals, vitamins and some essential amino acids. The leaves have very high nutritional value and contain nutrients like potassium, calcium, sodium, proteins, copper, manganese, and fibre.

Researchers agree that the active constituents in form of minerals and phytochemicals, which are stored in the various parts of the plant such as the fruits, seeds, leaves, root and bark, give utazi some of its therapeutic properties.

Actions

Studies have shown that the whole plant exhibits the following pharmacological actions: analgesic, antitumour, broad spectrum antimicrobial (antibacterial, antifungal, antiparasitic and antiviral), antipyretic, antioxidant, anti-inflammatory, antiulcer, anti-sickling, anti-asthmatic, mild expectorant, hypoglycemic, hypolipidemic, hepatoprotective, digestive tonic and laxative properties.

Preparations

The vital medicinal constituents can be extracted either through blending, chewing, infusing and decoction. However, the methods of preparing utazi for medicinal use depend on the part of the plant being desired for use.

The fresh leaves or the stem can be chewed or the sap extracted with water or palm wine. The whole plant can equally be infused with boiling water (as tea) or by boiling (decoction). In some cases, the dried or fresh leaves are prepared as tincture (i.e. extraction in alcoholic beverages).

Dosage form and uses of utazi

Utazi has a bitter-sweet taste and is often used as a local spice and vegetable for preparing foods,  such as abacha, nkwobi, unripe plantain porridge, ugba, local soups such as nsala (white soup), sauces, salads and isi ewu. It is an excellent source of protein and past studies show that utazi leaves are suitable for use in food production due to the high amino acid contents.
