The tree moringa oleifera grows fast and it is from South Asia and the tropical regions. The leaves of it are used as cures in natural medicine methods and this was known for centuries back in the Ayurveda system. It even aids in more than 300 health issues.
Since it grows really fast in those world areas, it was used mainly in Senegal, India and Malawi. There it is used as the best healthiest food they can get and they can harvest it during the whole year.
I tried to grow such a tree for two years now, and really, it grows fast like weed. For people in third world countries, it is an excellent nutritious food to have.
But, it won’t be a good idea to plant it in your yard for health aims; the leaves are small and it is hard to harvest them each from every stem.
Those leaves are tiny and delicate and you will see that it is a trouble to take care of this plant all the time. So, the moringa is healthy and beneficial only after harvesting.
