The term Coconut can refer to the entire coconut palm, the seed, or the fruit, which, botanically, is a drupe, not a nut. The spelling cocoanut is an archaic form of the word. The term is derived from 16th-century Portuguese and Spanish coco, meaning "head" or "skull", from the three indentations on the coconut shell that resemble facial features.
The coconut is known for its great versatility as seen in the many uses of its different parts and found throughout the tropics and subtropics. Coconuts are part of the daily diets of many people. Coconuts are different from any other fruits because they contain a large quantity of "water" and when immature they are known as tender-nuts or jelly-nuts and maybe harvested for drinking. When mature, they still contain some water and can be used as seednuts or processed to give oil from the kernel, charcoal from the hard shell and coir from the fibrous husk. The endosperm is initially in its nuclear phase suspended within the coconut water. As development continues, cellular layers of endosperm deposit along the walls of the coconut, becoming the edible coconut "flesh". When dried, the coconut flesh is called copra. The oil and milk derived from it are commonly used in cooking and frying; coconut oil is also widely used in soaps and cosmetics. The clear liquid coconut water within is potable. The husks and leaves can be used as material to make a variety of products for furnishing and decorating. It also has cultural and religious significance in many societies that use it.
Eating coconuts are excellent for one’s immunity. They are antiviral, antifungal, antibacterial, and anti-parasitic, meaning they kill harmful bacteria, viruses, fungi, and parasites. Because of that, if you consume coconut in any of its various forms (whether it be raw coconut, coconut oil, coconut milk, coconut butter, etc.), it can help treat some of mankind’s worst and most resilient of illnesses such as influenza, giardia, lice, throat infections, urinary tract infections, tapeworms, herpes, gonorrhea, bronchitis, and numerous other ailments caused by microbials.
