Dr. Huynh Tan Vu from the Ho Chi Minh City University of Medicine and Pharmacy Hospital points out that while the pulp and juice of limes are commonly used, the peel is often discarded. However, the peel offers numerous health advantages.
Providing high nutritional value
Lime peel is very nutritious, rich in dietary fiber and vitamin C, with 6 grams of it providing 9% of the recommended daily intake. It also contains calcium, potassium, magnesium, and D-limonene, a compound that contributes to the lime’s distinctive aroma and various health benefits.
Improving oral health
Tooth decay and gum infections, commonly caused by Streptococcus mutans, can be combated with lime peel extract. In-vitro studies indicate that lime peel extract inhibits the growth of this bacteria effectively, with higher doses showing greater effectiveness.
Lime peel also contains antimicrobial compounds that target common oral bacteria.
Providing antioxidants
Lime peel has a higher antioxidant activity than grapefruit or orange peel. It is especially rich in D-limonene and vitamin C, which help reduce the risk of diseases like heart disease and type 2 diabetes by reducing oxidative stress and protecting against cellular damage.

Containing antibacterial and antifungal properties
Lime peel exhibits antibacterial and antifungal properties. Research has shown it can significantly inhibit the growth of antibiotic-resistant bacteria and combat drug-resistant fungal infections that cause skin problems.
Boosting the immune system
Lime peel can enhance immune system functionality due to its flavonoid and vitamin C content. Studies have demonstrated improved immune responses in animals and reduced severity and duration of colds in humans.
Enhancing cardiovascular health
Flavonoids, vitamin C, and pectin in lime peel contribute to better heart health. Research indicates these compounds can reduce blood sugar levels, lower bad cholesterol, and increase good cholesterol.
Preventing cancer
The intake of flavonoids and vitamin C found in lime peel has been associated with a reduced risk of certain cancers. D-limonene, in particular, has shown potential against stomach cancer in both in-vitro and animal studies.
Treating gallstones
D-limonene in lime peel may help dissolve gallstones, presenting a possible non-surgical treatment option. Studies have shown effective results in a significant percentage of patients.
Lime peel also has applications in household cleaners and beauty products, making it a versatile and beneficial component of the fruit.
