Efirin (Nchanwu, Scent Leaf, African Basil, Clove Basil, Ocimum gratissimum).This highly aromatic herb is used in pepper soups, salads, pottages; and as a vegetable in its own right. Medicinal applications include using the crushed leaf to stop nose bleeds, as a digestive aid, a decongestant for head colds, bronchitis and sinusitis; as an aphrodisiac and as an antiseptic. The leaf is also chewed traditionally for tooth and gum problems.

Reconstituted dried leaves, though less aromatic, are an acceptable substitute for cooking. Holy basil or common basil are good alternatives.
