Leaf and herb
Utazi
A distinctive bitter leaf used to sharpen rich soups, sauces and garnishes.

Field note
Utazi is used for deliberate bitterness and aromatic contrast. Quantity matters: a little can define a dish, while too much can dominate it.
Research, not a remedy
Health research
Research on Gongronema latifolium extracts is mainly laboratory or animal based. A 90-day rat study found dose- and sex-specific safety signals at high extract doses, reinforcing that concentrated preparations should not be equated with culinary leaves. Reliable human clinical evidence was not identified.
