There exist varieties of pusley with variation in leaf size, thickness, and leaf arrangement and pigment distribution.

    • Research studies show that consumption of foods rich in omega-3 fatty acids may reduce the risk of coronary heart disease, stroke, and help prevent the development of ADHD, autism, and other developmental differences in children.

    • It is an excellent source of Vitamin-A, (1320 IU/100 g, provides 44% of RDA) one of the highest among green leafy vegetables. Vitamin-A is a known powerful natural antioxidant and an essential vitamin for vision. It is also required to maintain healthy mucosa and skin.

Both pigment types are potent antioxidants and have been found to have antimutagenic properties in laboratory studies. [Proc. West. Pharmacol. Soc. 45: 101-103 (2002)].

Although antioxidant properties are significantly decreased on frying and boiling, its minerals, carotenes, and flavonoids may remain intact with steam cooking.

    Here are some serving tips:

    • Fresh, raw leaves can be used as salad and as vegetable juice.

    • Fresh, tender leaves are used in salads. Sautéed and gently stewed stems and leaves served as a side dish with fish and poultry.

    Safety profile

    Purslane contains oxalic acid, a naturally-occurring substance found in some vegetables, which may crystallize as oxalate stones in the urinary tract in some people. 100 g fresh leaves contain 1.31 g of oxalic acid, more than in spinach (0.97 g/100 g) and cassava (1.26 g/100 g). It is, therefore, people with known oxalate urinary tract stones are advised to avoid eating purslane and certain vegetables belonging to Amaranthaceae and Brassica family. Adequate intake of water is therefore encouraged to maintain normal urine output. (Medical disclaimer).
