A widely grown plant in the Philippines, malunggay is a plant with the scientific name Moringa oleifera. It is simply called “moringa” by English speakers.
Moringa is a tree known as sajina in South Asian countries like India. In English, it is sometimes referred to as horseradish tree or horseradish plant, although it’s a different species from the horseradish that Westerners know. The tree grows fast and survives well in drought conditions.
