Moringa seed oil contains polyunsaturated fatty acids (PUFAs) such as linoleic acid, linolenic acid and oleic acid. The PUFAs are good for cholesterol control. Other fatty acids present are

The high protein value is from the amino acid, which makes up 30% of the total weight. The amino acid content is in leaves unlike in most other plants where they are in the seeds.

Moringa has phytosterols such as sitosterol, kampesterol, stigmasterol which are precursors of hormones. Galactagogue are made of phytosterols. They help to increase estrogen and milk production in breastfeeding mothers.

High β-carotene content means moringa oleifera has more vitamin A than pumpkin, and carrots, though drying, can reduce the content.

Although there are 13 species of moringa, moringa oleifera is the most studied type. It has many health and nutritive benefits. They have used it for a long time in India for traditional medicine, such as Ayurvedic and Unani system.

Toxicity: Though moringa plant is considered a safe plant, some product of the plant are not entirely safe. Roasted Moringa oleifera seeds may contain mutagens such as 4-(α-lramnopyranosyloxy)-
benzylglucosinolate that can damage the DNA.

The leaves have a high saponin content. Saponins can reduce the bioavailability of minerals such as zinc and magnesium. The root and bark contain toxic substances – spirochin, phytochemical benzothiocyanate, moringin alkaloids.
