I found this little green leaf in my soup and I knew it! Moringa oleifera, a multipurpose tree native to the foothills of the Himalayas in northwestern India and cultivated throughout the tropics.

Moringa Oleifera contains an enormous amount of nutritional content; vitamins, minerals, and amino acids which are critical for good health. It is loaded with calcium, iron, potassium, protein, Vitamin A and C, and is said to have many properties which promote a healthy body to fight cancer. It is known to have anti-inflammatory, anti-viral, antioxidant, anti-allergenic, and pain relief uses.

What I can say is this is a superb green leaf and read about it here:
