Quick Summary

Lime (Citrus aurantiifolia) is a citrus fruit traditionally used in various cultures, including Indonesia and Mexico, for medicinal purposes. It contains bioactive compounds such as essential oils, flavonoids, and polyphenols that may have antioxidant, anti-inflammatory, antimicrobial, and immunomodulatory properties. Research into extraction technologies and valorization of citrus by-products is ongoing. However, there is limited direct clinical evidence on the medicinal benefits of lime, and its safety profile has not been thoroughly studied in controlled human trials.

What Is It

Lime (Citrus aurantiifolia) is a small green citrus fruit belonging to the Rutaceae family. It is commonly used as a flavoring agent in food and beverages and has a history of use in traditional medicine in several regions around the world.

Traditional Uses

  • Used in ethnomedicine for various acute conditions and chronic diseases.
  • Part of remedies in Indonesian and Mexican traditional medicine systems.
  • Included among numerous medicinal plants used traditionally to manage hypertension.

Active Compounds

Lime contains several bioactive constituents, including:

  • Essential oils
  • Flavonoids
  • Polyphenols

These compounds contribute to the fruit’s potential antioxidant, anti-inflammatory, antimicrobial, and immunomodulatory activities.

Potential Benefits with Evidence Levels

  • Traditional use in ethnomedicine: Supported by ethnobotanical surveys but lacks robust clinical trial data.
  • Bioactive compounds with antioxidant, anti-inflammatory, and antimicrobial activities: Evidenced by preclinical and phytochemical studies; clinical significance remains unestablished.
  • Potential immune enhancement through citrus by-products: Observed in preclinical animal (aquaculture) models; relevance to humans is unclear.
  • Traditional management of hypertension: Reported in ethnopharmacological studies; direct clinical trials on lime specifically are lacking.

Side Effects

There is a lack of systematic clinical data on adverse effects specifically linked to lime consumption or its extracts. General caution is advised due to possible variability in compound concentrations and preparations.

Drug Interactions

No specific evidence currently exists on drug interactions involving lime.

Who Should Avoid It

No specific contraindications are documented. However, due to insufficient clinical safety data, standard precautions are recommended. Pregnant and breastfeeding individuals should exercise caution because safety has not been established.

Evidence Limitations

  • Lack of controlled human clinical trials specifically targeting Citrus aurantiifolia for medicinal uses.
  • Ethnobotanical data often suffer from methodological weaknesses, including inadequate taxonomic validation and non-standardized reporting.
  • Most evidence derives from traditional use, preclinical studies, or evaluations of citrus by-products/extracts rather than isolated lime.
  • Safety and toxicity profiles are inadequately assessed in clinical contexts.
  • No established clinical efficacy or safety data for pregnancy and breastfeeding periods.
