Other studies suggest other effects: antibacterial, anti fungal, anthelmintic, anti parasitic, anti tumor, anti HIV, anti-bone resorption, antispasmodic, antipyretic, antidiarrheal, antiallergic, immunomodulation, hypolipidemic, anti microbial, hepatoprotective, and gastroprotective.

Antibacterial / Phytochemicals:

Study showed that leaf extracts of M. indica possess some antibacterial activity against S aureus, E coli, P aeruginosa and provides a basis for its medical use in Uganda. Phytochemical study showed saponins, steroids and triterpenoids, alkaloids, coumarins, anthracenocides, flavonones, tannins and reducing sugars.

Hematologic benefits:

Effects of Aqueous Extract of Mangifera indica L. (Mango) Stem Bark on Haematological Parameters of Normal Albino Rats: Stem bark extracts of MI showed positive effects on the haemopoietic system of test rats.

Antiinflammatory, Analgesic and Hypoglycemic: Anti-inflammatory, analgesic and hypoglycemic effects of Mangifera indica Linn. (Anacardiaceae) stem-bark aqueous extract:

Results of the study support the folkloric use of the plant for painful arthritic and other inflammatory conditions, as well as T2DM.

Anti-Clostridium tetany activity or anti-Tetanus:

Study showed both the ethereal and ethanolic fractions of leaf extracts showed anti-clostridium tetani activity.

Anti-asthmatic:

Mangifera indica stem bark effect on the rat trachea contracted by acetylcholine and histamine: Study showed MI blockage of histaminic and muscarinic receptors, supporting the traditional use of MI stem back in the treatment of asthma.

Immunostimulant:

Immunomodulatory activity of alcoholic extract of Mangifera indica L. in mice: Study showed increased humoral antibody titer and delayed type hypersensitivity in mice suggesting a potential for a drug with immunostimulant properties.

Antihyperglycemic:

Study showed leaf extract of MI possess hypoglycemic activity, possibly due to reduction in intestinal absorption of glucose.

Flavonoids / Antihyperlipidemic Effect:

Flavonoids from M indica effectively reduce lipid levels in serum and tissues of rats with induced-hyperlipidemia. Degradation and elimination of cholesterol were enhanced.

Antioxidant:

Oral administration of flavonoids showed significant antioxidant action in cholesterol-fed experimental rats. The activities of free radical-scavenging enzymes were significantly elevated and lipid peroxide content was significantly reduced in flavonoid-treated hypercholesterolemic rats.

Anti-diarrheal Activity:

Study of the methanolic and aqueous extracts of seeds of M indica showed significant anti-diarrhea activity, the effect partly attributed to the effect on intestinal transit.

Anti-Diabetic Activity:

Study showed all extracts had significant antihyperglycemic effect in type 2 model rats. The ethanol extracts of stem-barks reduced glucose absorption gradually during the whole perfusion period in type 2 rats.

Ethnopharmacology / Mangiferin:

Mangiferin is a major C-glucosylxanthone from the stem bark, leaves, heartwood, roots and fruits of M indica and has been reported to have a variety of pharmacologic activities including antioxidant, radioprotective, antitumor, immunomodulatory, anti-allergic, anti-inflammatory, antidiabetic, antibacterial, among others, supporting the numerous traditional uses of the plant.
Polyphenols / Antiulcerogenic Activity:

Study showed oral pretreatment with mangifera leaf decoction decreased the severity of gastric damage in induced-gastric lesions. Two main phenolic compounds isolated were mangiferin and C-glucosyl-benzophenone. The findings show the potential gastroprotective properties of the aqueous decoction from M indica leaves.

Anti-Cancer / Polyphenols:

A Texas Agrilife Research study by food scientists Dr. Susanne Talcott and Dr Steve Talcott found that polyphenol extracts from mango promote anticancer activity in certain colon and breast cancer cells in lab. The polyphenols also showed some effects on lung, leukemia and prostate cancers. Polyphenolics, more specifically gallotannins, belong to a class of bioactive compounds that can prevent of stop cancer cells. Further studies will look into efficacy and clinical relevance.

Antibacterial:

Bioactive studies of Mangifera indica against bacterial isolated from urine samples showed the aqueous and ethanolic seed kernel extract good antibacterial activity against E coli, S aureus and S pyogenes. The antibacterial activity may be due to specific phytochemical components. Toxic components were not detected in the seed kernel and also appear to be a safe source of antioxidants.

Anti-Diabetic / Dipeptidyl Peptidase IV Inhibitory Activity:

The insulinotropic hormone, glucagon-like peptide 1 (GLP-1), a recent addition to diabetes therapy, is metabolized by dipeptidyl peptidase IV, and inhibition of DDP IV enhance GLP-1 which improved insulin secretion and glucose tolerance. Study on the methanolic extract of Mangifera indica leaves show the inhibitory effect on DPPIV and present a potential novel approach to diabetes therapy.

Toxicological Studies / No Lethality :

Study of stem-bark aqueous extract (MSBE), by oral or dermal administration, showed no lethality at the limit doses, with no adverse effects. it was non-irritating on skin, ocular, or rectal mucosa. It also had minimal irritancy following vaginal application.

Antidiabetic / Seed Kernels :

Study evaluated the hypoglycemic potency of seed kernels of Mangifera indica ethanol extract in STZ-induced diabetic rats. Results showed potent hypoglycemic activity. Possible mechanism of hypoglycemic action may be through potentiation of plasma insulin effect by increasing pancreatic insulin secretion from regenerated ß-cells or its discharge from bound insulin.

Mangiferin / Leaves :

Studies on mangiferin have shown antioxidant, antitumor, antiviral, anti-HIV, antipyretic, anticancer, antidiabetic, anthelmintic, immunomodulatory, neuroprotective properties. The study isolated the pharmacologically active mangiferin using an uncomplicated method, with ethanol as solvent to obtain a crude extract.

Memory-Enhancing / Fruit :

Study evaluated an ethanolic extract of fruit on cognitive performances in step down passive avoidance task and elevated plus maze task in mice. Treatment reversed the aging and scopolamine-induced memory deficits. Results showed effects that are memory-enhancing in nature.

Leaves as Functional Food:

Study showed aqueous extract of mango leaves to be rich in total phenols and total flavonoids, and as powerful antioxidants should be used in manufacture processes of the natural products as function foods or as dietary supplement with antidiabetic activity and hypoglycemic effect.

Cytotoxic Effect on Human Breast Cancer Cell Line:

Study evaluated the potential anticancer effects of an ethanolic kernel extract on breast cancer cell (MDA-MB-231 and MCF-7). Results showed the extract to be more cytotoxic to both estrogen positive and negative breast cancer cell lines than to normal breast cells.

Antimicrobial / Leaves:

Study evaluated various leaf extracts for antimicrobial activity against human and plant pathogenic bacteria. The hexane-ethyl acetate extract showed significant inhibition of almost all tested pathogenic organisms.

Combination Mangifera Extract and Methotrexate (MTX) in Rheumatoid Arthritis:

Study evaluated the possible therapeutic effects and safety of Mangifera indica extract (Vimang tablets, 300 mg) combined with methotrexate (MTX) on reducing disease activity in rheumatoid arthritis (RA). Only patients of MTX-Vimang group showed statistically significant improvement in DAS (disease activity score) 28 parameters. In the same group, 100% of patients decreased NSAIDs use.

Antihyperglycemic / Leaves:

Study evaluated the antihyperglycemic activity of ethanolic extract of leaves in alloxan induced diabetic rats. Results showed decreased alloxan effect and improvement in the laboratory parameters, suggesting a potential benefit for the treatment of diabetes mellitus.

Antioxidant / Protective Against Lipofundin-Induced Oxidative Stress:

Lipofundin is a lipid rich emulsion used in parenteral nutrition, known to induce an oxidative stress state characterized by increase lipid peroxidation and depletion of antioxidants. Study showed Vimang protects against Lipofundin-induced oxidative stress, reinforcing the antioxidant properties of the natural product.

Antihyperglycemic / Leaves:

The insulinotropic hormone, glucagon-like peptide 1 (GLP-1), a recent treatment for type 2 diabetes, is metabolized by DDP-IV (dipeptidyl peptidase IV). Inhibitors of DPP-IV enhance the level of GLP-1, which improve glucose tolerance and increase insulin secretion. Study showed a methanolic leaf extract to have potent in-vitro DPP-IV inhibitory activity, and may present a novel addition to the treatment of diabetes.

Anthelmintic / Leaves:

Various extracts of M. indica var. Thotapuri and M. indica var. Neelam were evaluated for anthelmintic activity against Pheretima posthuma. Results showed dose-dependent anthelmintic activity.
Immunostimulatory / Stem Bark:

Study evaluated the immunostimulatory effect of an ethanolic extract of M. indica stem bark in dexamethasone induced immunosuppressed male albino rats relative to immunoboosting effect of levamisole. Results showed a hepato-protective effect, a cholesterol lowering effect, and a stabilising tendency on the alanine aminotransferase concentrations.

Anti-Inflammatory / Colitis Model:

Study evaluated an aqueous extract of Mangifera indica on dextran sulfate sodium (DSS) induced colitis in rats. Results showed anti-inflammatory properties with improvement of clinical signs, reduction of ulceration, and reduced MPO activity when administered before DSS.
