Watermelon (or Citrullus lanatus) is a fruit of a vine-like herb originally cultivated in South Africa and was described by David Livingstone, an explorer of Africa, to have come from the Kalahari Desert.

Vitamin B6 is essential for protein metabolism and red blood cell metabolism. It also helps increase the amount of oxygen transported to our tissues and organs.

Vitamin C and beta-carotene are very potent antioxidants the body needs to fight against free radicals that can lead to cancer cell formation. Beta-carotene is also tightly connected with Vitamin A that helps the heart to function well. They are also natural anti-wrinkling and anti-ageing agents of the skin.

Lycopene is a naturally occurring red pigment found in plants and is also a very active carotenoid that functions as an antioxidant, as well. It also inhibits cholesterol formation and helps improve long term and short term memory.
