Cucumber is sweet in taste and cool in nature. Also known as Wanggua and Courgette. Cucumbers are rich in nutrients such as protein, calcium ions, phosphorus ions, iron ions, potassium ions, carotene, vitamin B2, vitamin C, vitamin E, and niacin. Cucumber helps to lose weight because it contains propylene glycol, which can inhibit the conversion of sugars into fat. Cucumber juice can also beautify, and is good for dry, wrinkled skin.
