Valuable information. Moringa is called in Tamil "Murungai" and in English "Drumstick" too. Very widely used in Sri Lanka especially in the Northern region for long time. Tropical tree - easily break if we climb. It has medicinal value as well. Cultivation is also very easy. Stem can be used for its propagation. The leaves, fruit and bark are used. Bark is for medicinal purpose only. I understand it is wasted in some countries and I hope your information will raise its value among them.
