In Chinese texts, the word "lemon" appears for the first time. The first reference is dated 1175, and a comprehensive description may be found in a text from 1178. These occurrences, together with other factors observed by historians, imply that the lemon was most likely brought to China between the 10th and the 12th centuries. Although no archaeological evidence exists to pinpoint its exact location, scholars assume it originated in the eastern Himalayan area of southern China, notably Upper Burma. The lemon was probably grown by the Greeks and Romans, and maybe even the Egyptians, although there are few signs of this culture today, save in mosaics. It might possibly be the citron (Citrus medica), which has long been renowned for its therapeutic virtues in both the east and the west. The lemon may have vanished from southern Europe a few times due to invasions and environmental shifts, only to reappearance later. The Arabs seized control of commerce after the barbarian invasions (350–400 AD). The Arabs acquired control of the commercial routes. They plan to spread the lemon throughout North Africa, Africa, and Spain, as well as throughout the Mediterranean basin, except the Italian and French shores. Finally, during the Crusades in the Middle East, Western, Eastern, and Northern Europeans would come across citrus fruits and develop a liking for them, bringing them back to their respective nations. The first greenhouses, known as orangeries, will emerge from there, where people would produce orange trees and lemon trees, followed by other types of tropical vegetation. Lemon was initially referred to as "limon," a phrase derived from the Italian limone, which in turn was derived from the Arabian-Persian limûn. In 1351, the term "citron" first appeared in French. The name "citron," which first appeared in 1398, is derived from the Latin citrus. In french and auther languages, he progressively supplanted "limon" in the common language. The word "lime" is derived from the Provençal limo. It first debuted in the language in 1555, whereas "lime" first emerged in 1782. Depending on the locale and type, this fruit has been given a variety of vernacular names (lemon gallet, corn bou, citrus-lime, lemon-lime, lime, Persian lime, Italian lime, sweet lime, sour lime). The fruit they are referring to is usually Citrus aurantifolia, often known as real lime or lime. It is also related to Citrus limon (lemon), Citrus reticulata (mandarin), and Citrus hystrix, popularly known as kaffir lime or kaffir lime, a bumpy-skinned fruit. In Thai cuisine, the leaves of the tree, as well as the zest and sometimes the juice of the fruit, are employed. Lime refers to the bitter, sour fruit of many lime varieties. Lime, on the other hand, refers to a citrus cultivar with a moderate flavor. The first documented reference of lime comes from an Arab source in the thirteenth century. As with lemon cultivation, it was most likely Arabs that introduced it to India, Persia, Palestine, Egypt, and Europe at the time. The lime tree is native to the Indian archipelago, where it may be seen growing wild. Although it has some culinary similarities to lemon, it is a completely separate botanical species (Citrus aurantifolia). Furthermore, it thrives at warmer temperatures.
