It is a plant called Moringa Oliefera. Google the most nutritious plant on earth.

Moringa leaf is best known for being an excellent source of nutrition and natural energy booster. This energy boost is not based on sugar, and so it is sustained. Moringa is also soothing. It can help lower blood pressure and is a sleep aid. Its detoxifying effect may come from Moringa’s ability to purify water. Moringa acts as a coagulant attaching itself to harmful material and bacteria.

While the continued use of Moringa for food by cultures in separate and distant parts of the world attest to its beneficial effects, Moringa is a recent ‘discovery’ of modern science. The leaves of Moringa Oleifera are nature’s multi-vitamin providing 25 x the iron of spinach 4 x the calcium of milk, 10 x the vitamin A of carrots, 15 x the potassium of bananas, 2 x the protein of yogurt, more vitamin D than milk and as much vitamin C as oranges. On top of that, science is proving Moringa to be a power house of nutrients; 92 are known to date, with the possibility of more yet to be identified. If that were not enough, Moringa has no known impurities.
