Question 1

How does Citrus aurantifolia work to support the immune system?

Accepted Answer

Citrus aurantifolia supports immune function primarily through its high vitamin C content and flavonoid profile. Vitamin C enhances phagocytic cell function and protects against oxidative stress by scavenging free radicals. Flavonoids like hesperidin act as antioxidants, while limonene provides antimicrobial properties. These compounds collectively contribute to its traditional use for immune support and scurvy prevention (Evidence Level: C).

Question 2

Does lime juice interact with prescription medications?

Accepted Answer

While Citrus aurantifolia has fewer documented drug interactions than grapefruit, caution is still warranted. Compounds like bergapten can cause photosensitivity, potentially increasing the risk of sunburn when taken with photosensitizing medications like tetracyclines or thiazide diuretics. Although the juice is generally safe, concentrated peel extracts may affect how the liver processes certain drugs. Patients should consult a healthcare provider regarding specific interactions (Evidence Level: C).

Question 3

What is the recommended daily dosage of Citrus aurantifolia for immune support?

Accepted Answer

The standard adult dosage for immune support and digestive aid is the juice of one to two limes daily, preferably diluted in water. This amount provides a natural source of vitamin C and flavonoids without exceeding safe upper limits. For peel extracts used in aromatherapy or topical applications, proper dilution is essential to prevent skin irritation (Evidence Level: Traditional).

Question 4

Is Citrus aurantifolia safe to consume during pregnancy?

Accepted Answer

Yes, Citrus aurantifolia is considered safe during pregnancy when consumed in typical dietary amounts, such as the juice of one to two limes per day. The vitamin C content aids in iron absorption, which is beneficial during pregnancy. However, pregnant women should avoid excessive intake to prevent heartburn or dental enamel erosion. Peel oil applications should be used cautiously due to potential photosensitivity risks (Evidence Level: C).

Question 5

What are the side effects of using lime peel oil on skin?

Accepted Answer

Topical application of Citrus aurantifolia peel oil can cause phytophotodermatitis due to the presence of bergapten. This reaction results in skin redness, blistering, or hyperpigmentation upon exposure to sunlight. To minimize risks, the oil must be properly diluted and users should avoid direct sun exposure after application. Individuals with sensitive skin should perform a patch test before use (Evidence Level: C).
