It is an Indian herb and I purchased some a couple months ago but have only taken once.

I'd never heard of it, but here is part of what Wikipedia has to say about it. Sounds like pretty good stuf!

Moringa cultivation is on the rise in Honduras. There it's becoming recognized as a profitable means of combating deforestation. As of 2012 support for Moringa farmers is being offered by the Honduran federal government through the Secretary of Agriculture and by private foreign investment firms. The plant's market potential is widespread given its easy growth and high nutrient content. As described below, the plant is valued for its leaves and high-protein seeds. It can also be made into defatted meal. Moringa oleifera silviculture is being promoted as a means to combat poverty and malnutrition.[5]
Moringa grows quickly in many types of environments. Much of the plant is edible by humans or by farm animals. The leaves are rich in protein, vitamin A, vitamin B, vitamin C and minerals.[4] One hundred grams of fresh Moringa leaves have: 2 times the protein of 100 gm yogurt (Moringa 8.3 g, yogurt 3.8 g); 4 times the calcium of 100 gm milk (Moringa 434 mg, whole cow milk 120 mg); the same potassium as 100 gm banana (Moringa 404 mg, banana 376 mg); the same vitamin A as 100 gm carrot (Moringa 738 mcg, carrot 713 mcg); 3 times the vitamin C of 100 gm orange (Moringa 164 mg, orange 46.9 mg.[6][unreliable source?] The leaves also contains antioxidants, anti-inflammatory and essential amino acids.[7][unreliable source?]
Feeding the high protein leaves to cattle has been shown to increase weight gain by up to 32% and milk production by 43 to 65%.[5] The seeds contain 30 to 40% oil that is high in oleic acid, while degreased meal is 61% protein.[8] The defatted meal is a flocculant and can be used in water purification to settle out sediments and undesirable organisms.[9]

Thanks Jan, I have heard it is suppose to be a great rejuvinator also.
