Lime (Citrus aurantiifolia) is a nutrient-dense citrus fruit exceptionally rich in vitamin C (ascorbic acid), citric acid, and active monoterpenes like limonene. Vitamin C serves as a crucial antioxidant that stimulates white blood cell production and function to fight off seasonal colds. Citric acid stimulates salivary and gastric juices to aid digestion, binds minerals to enhance iron absorption, and alkalizes urine to prevent certain kidney stones.

Generally safe. The citric acid can erode tooth enamel over time; rinse the mouth with plain water after drinking lime juice. Topical application of the peel oil can cause phototoxicity (severe sunburn) if the skin is exposed to direct sunlight.
