The lime fruit comes from Citrus acida not the lime or linden tree which we use as a tisane, lime flower tea. It is a member of the Rutaceae family and so is related to all the other citrus fruits, the lemon, grapefruit, Seville orange, sweet orange, bergamot orange, pommelo, kinnow mandarin and so on.
It is a small tree growing to about 8 feet tall with spines, so you have to be careful when picking limes. It is native to Asia but is cultivated in the West Indies and Italy , although in Italy the lime produced comes from Citrus limetta. The tree has small white flowers as do some other Citrus trees and the fruit skin is a green-yellow, resembling a small lemon or the Pakistani kagzi nimboo. It is from the skin that the valuable oil is produced, and that of the Italian lime resembles oil of bergamot, although it does not have the same properties as this or the oil from the bee balm, of the Monarda species.
Lime juice is used in South America along with that of the lemon to marinade fish so that it is ‘cooked’ with he juices rather than through heating. Because of its vitamin C content it was formerly used as an anti-scurvy fruit and sailors took it with them on long voyages. Now it is used in cookery and in the Indian subcontinent and West Indies , as well as other countries, for medicinal purposes.
In the Indian subcontinent lime oil is used for skin problems, including for removing dandruff from the scalp, and it is believed to be the most beneficial of fruits with sour juices. The juice or fruit is used to promote appetite and to aid digestion as well as to ease constipation, help the liver to function and to stop vomiting. (That, I know works.) It is also thought to be a blood purifier, so is good for skin eruptions, and for the heart.
If you are bitten by a mosquito and have a lime to hand, the juice will stop the irritation, although you shouldn’t use too much lime juice (everything in moderation) as it can induce photosensitivity. The juice mixed with gur (rock candy or jaggery) is said to be good if you have an enlarged spleen.
In Ayurvedic medicine the fruit is used to boost mental faculties, so used to help prevent the loss of memory as people age, and to strengthen the body tissues. It is also given as a tonic for the heart as well as for skin problems and gout.
In other medicine systems it is used for cancerous tumours, skin problems, such as to smooth the skin after the scabs of chicken pox and so on have fallen off, and to alleviate itching, as well as for sore throats as a gargle with or without honey.
It is an antidote to castor oil and croton oil poisoning (for example too much jamalgota, Croton tiglium) and has antioxidant and anti microbial properties as does the lemon.
As for the history of the lime in Western literature, Sir Thomas Herbert mentions it in his book “Travels” as he found it growing close to Mozambique in the mid-1600s along with “oranges and lemons” and William Bartram in his travel book published in 1773 states that Henry Laurens of Charleston, South Carolina, introduced “olives, limes, ginger, ever-bearing strawberry, red raspberry and blue grapes” into the American colonies after 1755.
You can use the lime instead of lemon juice in most recipes but it does impart a different flavour to dishes. Of course it’s good in cocktails too especially mojitas.
