Daun katuk (*Sauropus androgynus*) — a shrub native to Southeast Asia and tropical South Asia — has been eaten throughout the Indonesian archipelago as a green vegetable for centuries, valued particularly in Javanese and Sundanese tradition for its high protein content relative to leafy vegetables (approximately 7g per 100g fresh weight), its high calcium content, and its traditional use in stimulating breast milk production (galactagogue). In contemporary nutrition and natural health discourse, daun katuk has attracted attention for its nutritional density; in traditional practice, it was simply a kitchen garden staple whose value was experienced rather than analysed.
