The lemon is the common name for Citrus limon. The reproductive tissue surrounds the seed of the angiosperm lemon tree. The lemon is used for culinary and nonculinary purposes throughout the world. The fruit is used primarily for its juice, though the pulp and rind (zest) are also used, primarily in cooking and baking. Lemon juice is about 5% (approximately 0.3 mole per liter) citric acid, which gives lemons a tart taste, and a pH of 2 to 3. This makes lemon juice an inexpensive, readily available acid for use in educational science experiments. Because of the tart flavor, many lemon-flavored drinks and candies are available on the market, including lemonade.
The exact origin of the lemon has remained a mystery, though it is widely presumed that lemons first grew in India, northern Burma, and China. In South and South East Asia, it was known for its antiseptic properties and it was used as an antidote for various poisons. It was later introduced to Persia and then to Iraq and Egypt around AD 700. The lemon was first recorded in literature in a tenth century Arabic treatise on farming, and was also used as an ornamental plant in early Islamic gardens.It was distributed widely throughout the Arab world and the Mediterranean region between AD 1000 and AD 1150.
Pickled lemons, a Moroccan delicacyLemons entered Europe (near southern Italy) no later than the first century AD, during the time of Ancient Rome. However, they were not widely cultivated. The first real lemon cultivation in Europe began in Genoa in the middle of the fifteenth century. It was later introduced to the Americas in 1493 when Christopher Columbus brought lemon seeds to Hispaniola along his voyages. Spanish conquest throughout the New World helped spread lemon seeds. It was mainly used as ornament and medicine. In 1700s and late 1800s, lemons were increasingly planted in Florida and California when lemons began to be used in cooking and flavoring.

The lemon (Citrus × limon) is a small evergreen tree native to Asia, and the tree's ellipsoidal yellow fruit. The fruit is used for culinary and non-culinary purposes throughout the world, primarily for its juice, though the pulp and rind (zest) are also used in cooking and baking. The juice of the lemon is about 5% to 6% citric acid,
which gives lemons a sour taste. The distinctive sour taste of lemon
juice makes it a key ingredient in drinks and foods such as lemonade.

The origin of the lemon is a mystery, though it is thought that lemons first grew in Assam (a region placed in Northeast India), northern Burma, and China.A study of the genetic origin of the lemon reported that it is a hybrid between sour orange and citron.
Lemons were known to the Jews of Jerusalem, who, according to Josephus, pelted an errant high priest with them during a festival in the 90s BC,although Jewish tradition maintains that this was done with citrons, not lemons. They entered Europe near southern Italy no later than the 1st century AD, during the time of Ancient Rome. However, they were not widely cultivated. They were later introduced to Persia and then to Iraq and Egypt around 700 AD. The lemon was first recorded in literature in a 10th-century Arabic treatise on farming, and was also used as an ornamental plant in early Islamic gardens.It was distributed widely throughout the Arab world and the Mediterranean region between 1000 and 1150.
The first substantial cultivation of lemons in Europe began in Genoa in the middle of the 15th century. The lemon was later introduced to the Americas in 1493 when Christopher Columbus brought lemon seeds to Hispaniola
on his voyages. Spanish conquest throughout the New World helped spread
lemon seeds. It was mainly used as an ornamental plant and for
medicine. In the 19th century, lemons were increasingly planted in Florida and California.
In 1747, James Lind's experiments on seamen suffering from scurvy involved adding lemon juice to their diets, though vitamin C was not yet known.
