Coconut (Cocos nucifera L.) grows in tropical and subtropical regions and belongs to the family of Arecaceae subfamily Cocoideae.
There are two groups of coconut trees: tall and dwarf. The tall variety gives fruits between 6 and 10 years, while the dwarf variety between 4 and 5 years. The coconut is quite caloric, 354 calories in 10 grams of pulp.

The kernel contains about 70% oil that is used in cosmetics and nutrition.
What it is used for and where
Medical
The ethanol extract at 1.5% of the coconut husk has shown an antibacterial action against dental biofilm and can be used as an irrigation solution to overcome bacterial resistance with synthetic agents (2).
Some components of green dwarf coconut water, mainly caffeic acid and ascorbic acid, have demonstrated antioxidant and hepatoprotective activity and reduce DNA damage, thus reducing oxidative stress induced by ethanol metabolism in steatosis and alcoholic steatohepatitis (3).
Coconut water has been used as an intravenous solution in surgery (4).
This study believes that the fiber extract from the lemon peel acts, in certain amounts, on the central nervous system. The resulting anxiolytic and antidepressant effect is related by interaction with the serotonergic system (5).
Cosmetics
Used as a topical skin care treatment and for repairing the natural function of the skin barrier (6) due to the emollient and anti-infective properties of phenolic acids, vitamins and flavonoids.
Emollients have the characteristic of enhancing the skin barrier through a source of exogenous lipids that adhere to the skin, improving barrier properties by filling gaps in intercorneocyte clusters to improve hydration while protecting against inflammation. Emollients are described as degreasing or refreshing additives that improve the lipid content of the upper layers of the skin by preventing degreasing and drying of the skin. The problem with emollients is that many have a strong lipophilic character and are identified as occlusive ingredients; they are oily and fatty materials that remain on the skin surface and reduce transepidermal water loss. In cosmetics, emollients and moisturisers are often considered synonymous with humectants and occlusives.
