Fruit, roots, bark, rind.
- Nausea and fainting: Squeeze rind near nostril for irritant inhalation.
- Decoction of roots used for dysentery; root-bark as febrifuge.
- Crushed leaves applied to forehead for headaches.

In southwest Nigeria, roots, bark, stem, twigs, leaves and fruit used in treatment of malaria.
- Flavor: Use juice and grated rind. A pleasant ade.
- Substitute for true lemon.
- Good source of vitamin C.
- As fumigant, steaming brew of leaves under the blanket.
- Lime oil is extracted by steam distillation of the fruit rinds; used for colds, sore throats, bronchitis, asthma. Also for arthritis, obesity, cellulite and as tonic and astringent.
- Essential oils / Antifungal: Study on essential oils of three varieties of C. aurantifolia showed the plant to be very rich in monoterpenes, with limonene its major compound. The three extracts showed fungicidal inhibiting action to Phaeoramularia angolensis and presents an alternative to chemical fungicides used for Citrus fruit crops.
- Antiproliferative / Anti-cancer: Study of in vitro effects of several concentrations of lime juice (CLJ) showed significant inhibition of proliferation of human breast carcinoma cell line and assumes that protein components of the CLJ extract may have anti-proliferative effects on tumor cell lines.
- Antimicrobial: (1) Study investigating the antibacterial effects of two plants extracts showed Citrus aurantifolia showing promising borad spectrum antibacterial effects on human pathogens. (2) Antimicrobial study of bitter leaf (V. amygdalina) extract and lime (Citrus aurantifolia) juice against five organisms concluded both are potential antimicrobial agents.
- Antiaflatoxigenic: The essential oils of we medicinal plants were studied for its inhibition ofthe toxigenic fungus Aspergillus parasiticus.Citrus aurantifolia was found to inhibit both A. parasiticus and aflatoxin production. The study suggests some medicinal plants may be potential candidates for protection of food and feeds from toxigenic fungus growth and subsequent AF contamination.
- Antiproliferative / Colon Cancer Prevention: Study of the lime volatile oil of CA yielded 22 compounds, D-limonene, D-dihydrocarvone among the major componds. The oil showed 78% inhibition of human colon cancer cells, DNA fragmentation and apoptosis induction, results that suggested potential antiproliferative benefits in colon cancer prevention.
- Nephrolithiasis: Consumption of Citrus auratifolia Swingle in idiopathic calcium renal stone with hypocitraturia increased the urine volume, pH level and total citrate value, total potassium and decreased the calcium ration to urine citrate with consequent decrease of renal stone recurrence.
- Fertility Effects: Lime juice causes irregularity of the estrous cycle, partially blocks ovulation, and may possibly compromise fertility.
- Toxicity Studies: Acute and subchronic toxicity studies of water extract from roots of Citrus aurantifolia in rats showed no signs of toxicity and no significant histopathological changes in the internal organs.
- Weight Reduction / Decreased Food Intake / Limonene: Study investigated the effects of lime (Citrus aurantifolia) essential oils in reducting body weight, alone or in combination with ketotifen, an antihistamine drug that causes weight gain. Lime essential oil treatment displayed a reduction of body weight and food consumption in mice. In combination with ketotifen, there was significant suppression of weight gain, as well as decreased body weight. Oil analysis yielded 22 main components, with limonene (28.27%) as the principal one.
- Antioxidant: Study showed both juice and peel demonstrated antioxidant properties. In contrast to lime peel, excessive consumption of lime juice seems not to be beneficial and may be harmful because of an inadvertent U dose response.
- Commercial cultivation.
- Extracts, essential oils and supplements in the cybermarket.
