Quick Summary

Mango leaf (Mangifera indica) contains bioactive compounds such as mangiferin and phenolic compounds with potential antioxidant, anti-inflammatory, antimicrobial, and metabolic effects. It has been traditionally used for various medicinal purposes, including management of parasitic infections and oral health. Current research includes in vitro, in vivo, and limited human studies, but clinical evidence remains preliminary and requires further rigorous trials.

What is it?

Mango leaf refers to the leaves of the mango tree, Mangifera indica, a tropical fruit tree native to South Asia and widely cultivated worldwide. The leaves contain multiple bioactive substances, notably mangiferin, a polyphenol with various studied biological activities. Mango leaf extracts and preparations are used traditionally and are now the subject of scientific investigation for their potential health-promoting properties.

Traditional Uses

  • Management of parasitic infections including protozoa and helminths
  • Support for oral health, including treatment of oral pathogens
  • Traditional use in inflammatory conditions and metabolic regulation
  • General wound healing and antimicrobial purposes

Active Compounds

The main active constituents in mango leaves include:

  • Mangiferin: a xanthonoid polyphenol with antioxidant and anti-inflammatory properties
  • Phenolic compounds and flavonoids contributing to antioxidant activity
  • Other phytochemicals such as tannins and triterpenoids

Potential Benefits with Evidence Levels

  • Glycemic control and insulin sensitivity improvement in adults with prediabetes
    Moderate evidence from a randomized controlled trial showed daily mango consumption for 24 weeks improved fasting blood glucose, insulin sensitivity, and body composition (PMID: 40941087).
  • Reduction of inflammatory and muscle damage biomarkers during athletic training
    Low evidence from a pilot randomized crossover trial reported that mango puree supplementation for 4 weeks decreased inflammatory markers such as C-reactive protein and interleukin-6 in athletes (PMID: 41683347).
  • Support of metabolic syndrome components and cardiometabolic health
    Low evidence from a systematic review of animal and in vitro studies suggests beneficial effects on glycemic control, plasma lipids, endothelial function, and exercise performance (PMID: 38137871).
  • Antiparasitic potential against protozoa and helminths
    Low evidence from in vitro and animal studies indicates extracts have activity against malaria and helminth infections, though clinical validation is lacking (PMID: 41155688).
  • Antimicrobial effects on oral pathogens and potential reduction of dental caries
    Low evidence from a systematic review including 3 randomized controlled trials involving 130 subjects showed mango leaf extract mouthwash reduced salivary Streptococcus mutans and increased salivary pH (PMID: 38024868).
  • Potential anticancer activity, especially related to mangiferin
    Low evidence from preclinical studies suggests antioxidant, anti-inflammatory, and modulatory effects on cancer-related pathways in vitro and in animal models (PMIDs: 37627222, 41574708).

Side Effects

No specific adverse effects related to mango leaf or its extracts have been reported in the reviewed clinical trials or systematic reviews. Nevertheless, safety monitoring in further clinical studies is recommended.

Drug Interactions

There is limited direct evidence on drug interactions with mango leaf products. Some studies note potential risks of herbal-pharmaceutical co-use in populations using mango leaf alongside conventional medications and highlight the need for further research to clarify interaction profiles (PMID: 41259156). Caution is advised when using mango leaf products concurrently with other medicines.

Who Should Avoid It

Although no explicit contraindications are documented, use of mango leaf products should be cautious in vulnerable populations due to limited clinical safety data. Pregnant and breastfeeding women are advised to avoid use without medical supervision due to insufficient safety information.

Evidence Limitations

  • Most evidence originates from in vitro or animal studies, with limited human clinical trials.
  • Available clinical studies typically have small sample sizes and short follow-up periods.
  • Variability in extract preparations, doses, and formulations limits comparability.
  • Low oral bioavailability and solubility of mangiferin challenge clinical efficacy.
  • Lack of standardized protocols and validated biomarkers in many studies.
  • Variations in chemical composition due to plant source and extraction methods.
  • More rigorous, large-scale randomized controlled trials are needed to confirm benefits and safety.
