The juice of its fruits, limes, is used for the preparation of drinks, including caipirinha. The emergence of such beverages may be linked to maritime transport. In 1795, the British Navy began supplying lime and lemon juice to supplement the ration of rum that was given to sailors to fight cold in order to combat scurvy, a disease caused by lack of vitamin C that sailors suffered in their long voyages. Sweet lime seems to be present since ancient times in the gardens of Real Alcázar. The Spanish poet and humanist Rodrigo Caro visited many historic sites in and around Seville, experience that he wrote in 1634 in his work Antiquities and principality of the Honorable city of Seville. He also wrote about the Real Alcázar and its gardens: his description perhaps provides the most complete and accurate picture of how the garden designed by the kings of the House of Austria Charles V and Philip II was. Caro speaks of a 'thick forest of citrons, limes, lemons and oranges' in the Huerta de la Alcoba. This orchard was a land that was leased to individuals to cultivate and exploit agriculturally the designated trees, plus vegetables. There were several ponds and waterwheels with their respective wells. As happened in the Islamic period, the gardens of the Real Alcázar at the time of the Habsburgs had an ornamental use that didn’t necessarily compete with other agricultural use, given the presence of orchards also included in the palace grounds.
