Lime (Citrus aurantifolia)

"Lime" refers to a number of citruses with typically round, green to yellow fruits, which are frequently associated with the lemon. Lime fruit, particularly its juice and zest, is used in food and beverages for its flavor and floral aroma. Due to its acidity, it is also used for pickling. Dried limes are typically used as flavoring in Persian cuisine. According to the U.S. Food and Drug Administration (FDA), lime has generally recognized as safe (GRAS) status for use in food in the United States when it is taken by mouth in amounts commonly found in foods.

BACKGROUND

"Lime" refers to a number of citruses with typically round, green to yellow fruits, which are frequently associated with the lemon. Lime fruit, particularly its juice and zest, is used in food and beverages for its flavor and floral aroma. Due to its acidity, it is also used for pickling. Dried limes are typically used as flavoring in Persian cuisine. According to the U.S. Food and Drug Administration (FDA), lime has generally recognized as safe (GRAS) status for use in food in the United States when it is taken by mouth in amounts commonly found in foods.

Lime is believed to be native to the tropical regions of Asia and the Malay Archipelago. It may have been brought to Persia, Palestine, Egypt, and Europe by Arabs from India at about the same time as sour orange and lemon. It is thought that lime was introduced to Florida in the United States during the establishment of St. Augustine in 1565. Today, south Florida is the source of more than 85% of North American limes.

In the 1700s, British sailors consumed limes and other citrus fruits on board ships to prevent rickets, which occurs from a lack of vitamin C. Hence, the sailors derived the nickname "limey."

Evidence of limeade's use in iron-deficient women is conflicting. Preliminary studies have observed a protective effect of lime against cholera, but there are no well-designed clinical trials at this time evaluating the use of lime in the treatment of other conditions.

EVIDENCE TABLE

Conditions

Uses
disclaimer: These uses have been tested in humans or animals. Safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider.
Grade*

Cholera (prevention)

One study found that lime juice used in sauces might aid in the prevention of cholera. Another preliminary study suggested that using limes in the main meal may also have a protective effect; both studies were investigated by the same primary author. Additional study is needed before a firm recommendation can be made.

C

Iron deficiency

There is conflicting evidence regarding the effectiveness of lime's ability to increase iron absorption. Additional study is needed before a firm conclusion can be drawn.

C

*Key to grades: A: Strong scientific evidence for this use; B: Good scientific evidence for this use; C: Unclear scientific evidence for this use; D: Fair scientific evidence against this use (it may not work); F: Strong scientific evidence against this use (it likely does not work).

TRADITION

The below uses are based on tradition, scientific theories, or limited research. They often have not been thoroughly tested in humans, and safety and effectiveness have not always been proven. Some of these conditions are potentially serious, and should be evaluated by a qualified healthcare provider. There may be other proposed uses that are not listed below. Acne, antimicrobial, antioxidant, antiseptic, arthritis, asthma, astringent, bad breath, cancer, chilblains (inflammation caused by the cold), colds, contraceptive (birth control), cough, detoxification, diarrhea (oral rehydration), diuretic (increases urine), dysentery (severe diarrhea), dyspepsia (upset stomach), fever, flu, genitourinary tract disorders, hair loss, headache, heart palpitations, hemorrhage (intestinal bleeding), hemorrhoids, HIV, immunomodulator, indigestion, insect bites, jaundice, liver disorders, nausea, neuralgia (nerve pain), rheumatism, sexually transmitted disease (prevention), scurvy (vitamin C deficiency), stimulant, stomach ailments, tonic, ulcers, varicose veins.

DOSING

disclaimer: The below doses are based on scientific research, publications, traditional use, or expert opinion. Many herbs and supplements have not been thoroughly tested, and safety and effectiveness may not be proven. Brands may be made differently, with variable ingredients, even within the same brand. The below doses may not apply to all products. You should read product labels, and discuss doses with a qualified healthcare provider before starting therapy.

Adults (over 18 years old)

There is no proven effective dose for lime. A limeade drink containing 25 milligrams ascorbic acid (vitamin C) has been studied, but showed no clear benefit.

Children (under 18 years old)

There is no proven effective dose for lime in children.

SAFETY

disclaimer: The U.S. Food and Drug Administration does not strictly regulate herbs and supplements. There is no guarantee of strength, purity or safety of products, and effects may vary. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy. Consult a healthcare provider immediately if you experience side effects.

Allergies

Avoid in individuals with a known allergy or hypersensitivity to lime. When applied on the skin, lime oil may cause hypersensitivity. Distilled lime oil may be non-irritating, non-sensitizing and non-phototoxic to human skin, but expressed lime oil and lime peel may cause phototoxic skin reactions.

Side Effects and Warnings

Lime juice, peel and oil are generally considered safe to consume in food amounts, and few reported side effects, including photosensitivity, headaches, diarrhea and dental effects, have been noted in case reports and clinical studies. Lime has GRAS (generally recognized as safe) status for use in foods in the United States.

Lime is possibly safe for use when used orally in medicinal amounts, or when lime oil is applied on the skin in cosmetics.

Lime is possibly unsafe when applied on the skin in large amounts. Lime oil contains oxypeucedanin, which may cause photosensitization.

Lemon and lime juice are widely used for douches among women at high risk of HIV transmission. However, there is no evidence that lime douche is effective for this use and caution is advised.

Theoretically, distilled lime oils may promote tumors in the presence of carcinogenic chemicals.

Pregnancy and Breastfeeding

Lime is not recommended for pregnant or breastfeeding women if using in amounts greater than those typically found in foods because of insufficient available evidence.

INTERACTIONS

disclaimer: Most herbs and supplements have not been thoroughly tested for interactions with other herbs, supplements, drugs, or foods. The interactions listed below are based on reports in scientific publications, laboratory experiments, or traditional use. You should always read product labels. If you have a medical condition, or are taking other drugs, herbs, or supplements, you should speak with a qualified healthcare provider before starting a new therapy.

Interactions with Drugs

Based on laboratory studies, lime may interfere with the way the body processes certain drugs using the liver's cytochrome P450 (CYP450) enzyme system. As a result, the levels of drugs metabolized via CYP450 may be affected in the blood, and may cause potentially serious adverse reactions. Some drugs that may be affected are benzodiazepines, calcium channel blockers, some HIV antivirals, some HMG CoA reductase inhibitors and some macrolide antibiotics.

Based on laboratory study, fresh lime juice in concentrations above 5% may increase the transport of digoxin across cell membranes. As a result, the levels of digoxin may be affected in the blood, and may cause altered effects or potentially serious adverse reactions, including overdose.

Concentrations of lime juice may enhance the absorption of [(14)C]-mannitol; this could result in excessive diuresis and lead to electrolyte abnormalities or kidney failure. Caution is advised.

Theoretically, use of lime oil with photosensitizing agents may increase the risk of phototoxicity.

Interactions with Herbs and Dietary Supplements

Based on laboratory study, lime may interfere with the way the body processes certain herbs or supplements using the liver's cytochrome P450 (CYP450) enzyme system. As a result, use may cause the levels of other herbs or supplements to be too high or too low in the blood. It may also alter the effects that other herbs or supplements possibly have on the P450 system.

Based on laboratory and human study, there is conflicting evidence as to whether ascorbic acid (vitamin C) in limeade affects iron absorption. Preliminary study shows that limeade may increase iron absorption, but human study did not show any therapeutic effect in iron deficient women.

Based on laboratory study, a 30% concentration of lime juice may enhance the absorption of [(14)C]-mannitol; this could result in excessive diuresis, and lead to electrolyte abnormalities or renal failure.

Theoretically, use of lime oil with photosensitizing agents may increase the risk of phototoxicity.

Theoretically, concomitant use of herbs and supplements containing psoralens might potentiate effects and adverse reactions. Caution is advised.
