Geographic Distribution and Habitat –
The origin of grapefruit is uncertain. It is supposed that it does not come from South-East Asia, but from Central America (Barbados or Bahamas) but it becomes difficult to demonstrate how it could reach the Mediterranean Sea from there; The hypothesis that he came to Europe together with his ancestor, the sweet orange, from the Far East through Asia to the Silk Road, is more similar. Today grapefruit is grown in all countries with a temperate climate.

Description –
The Citrus paradisi is an ancient hybrid, probably between the sweet orange and the pomelo, but for centuries it is now an autonomous species. Grapefruit is a very vigorous plant, which can reach 12 meters in height, with a rounded shape and dense foliage. It has dark-green ovate leaves, with winged petioles and a flexible spine at the axilla. The flowers are large, generally in axillary inflorescences (hence the English “grapefruit”, that is, fruits gathered in clusters). It has fruits with a juicy, bitter-acidulous pulp, yellow in color, or pink-red according to the variety. The seeds are white and polyembryonic.
Grapefruit is classified commercially based on:
– maturation period (early, mid-season and late);
– color of the pulp (light or pigmented);
– presence of seeds: with seeds or apireni.
The common name grapefruit can refer both to fruit and to its tree.

Grapefruit has been grown in Europe for a long time only as an ornamental plant. The fruit became popular and then grown in intensive plants only in the nineteenth century.
In addition to food uses such as fresh fruit, juices, drinks, etc. some studies show important antimycotic, antimicrobial and antibacterial properties of the GSE (Grapefruit-Seed Extract).
In the last thirty years, through various studies, it has been noticed however that in countries where grapefruit juice consumption is high (with quantities of even 4-8 liters per day) negative interferences of this drink occurred on some pharmacological therapies. For this reason, studies have been deepened that have led to clarify the enzymatic mechanisms of action and, therefore, it is always good prior medical consultation, for those who use some drugs, in the intake of drinks based on grapefruit juice .
