It is commonly used in local dishes such as sinigang, nilaga, and stir-fried meals. Rich in vitamins A, C, and K, as well as calcium and fiber, this native green helps boost immunity and supports good digestion. Its tender leaves and crunchy stems make it a healthy and delicious choice for everyday Filipino cooking.
