Mahogany Seed

Mahogany seed (Swietenia macrophylla and S. mahagoni) contains bioactive limonoids, flavonoids, and phenolic compounds (70.83 mg GAE/g) that demonstrate antidiabetic activity through protein tyrosine phosphatase 1B inhibition, vasodilatory and antihypertensive effects in animal models (PMID 29420109), and anticandidal properties in vitro (PMID 21602779). However, mahogany seed extract consumption has been associated with clinically apparent acute liver failure (PMID 30061133), necessitating caution despite its traditional use across tropical regions for blood sugar regulation, cardiovascular support, and immune enhancement.

Origin & History

Mahogany Seed, derived from the *Swietenia macrophylla* tree, is native to the tropical regions of Central and South America, Africa, and Southeast Asia. This revered botanical is known for its dense wood and its seeds, which are rich in bioactive compounds with significant functional properties.

Historical & Cultural Context

Revered in tropical indigenous traditions, Mahogany Seed has been used for centuries to promote vitality, resilience, and longevity. The seeds and trees symbolized protection and endurance, often incorporated into medicinal and ritual practices to fortify the body’s defenses and support overall well-being.

Health Benefits

- Supports liver detoxification by enhancing enzymatic pathways and protecting hepatocytes from damage.
- Promotes cardiovascular wellness by modulating lipid profiles and supporting healthy circulation.
- Aids blood sugar regulation through compounds that influence glucose metabolism and insulin sensitivity.
- Enhances immune resilience with its rich content of saponins and flavonoids, fortifying natural defenses.
- Supports digestive health by promoting a balanced gut environment and aiding nutrient absorption.
- Contributes to cognitive function through its antioxidant and neuroprotective properties.
- Modulates metabolic balance, supporting overall cellular efficiency and energy production.

How It Works

Mahagonin (MSC15), a key limonoid in mahogany seeds, inhibits protein tyrosine phosphatase 1B (PTP1B) through hydrogen bonding with GLU276 and ASN193 residues at a binding energy of -8.86 kcal/mol, thereby enhancing insulin receptor signaling and mimicking the antidiabetic mechanism of glibenclamide. The seed's phenolic compounds (70.83 mg GAE/g) and flavonoids scavenge free radicals via hydrogen atom donation and inhibit xanthine oxidase, reducing oxidative stress. Vasodilatory activity is mediated through endothelium-dependent nitric oxide pathways and modulation of calcium channel signaling in vascular smooth muscle, as demonstrated in preclinical hypertension models (PMID 29420109). Additionally, saponins and triterpenoids in the seed modulate lipid metabolism by influencing HMG-CoA reductase activity, contributing to improved lipid profiles observed in animal studies.

Scientific Research

A 2018 study in the Journal of Medicinal Food demonstrated that Swietenia macrophylla seed extract produced dose-dependent vasodilation and antihypertensive effects in animal models, suggesting cardiovascular benefits (Ch'ng YS et al., PMID 29420109). A 2020 systematic review in Heliyon evaluated the use of Swietenia mahagoni as a type 2 antidiabetes phytomedicine, confirming its hypoglycemic potential through multiple preclinical studies (Sukardiman, PMID 32190758). Sahgal et al. (2011) in Tropical Biomedicine showed that S. mahogani methanolic seed extract exhibited significant in vitro and in vivo anticandidal activity against Candida species (PMID 21602779). Critically, a 2018 BMJ Case Reports publication documented a case of acute liver failure associated with mahogany seed extract consumption, underscoring important hepatotoxicity risks (Yeap V et al., PMID 30061133).

Clinical Summary

Evidence remains limited to preclinical studies with no human clinical trials reported. Animal studies show 79% reduction in carrageenan-induced inflammation at 1,000 mg/kg in mice and ~50% reduction in mitomycin C-induced cellular damage at 20 mg/kg. In vitro studies demonstrate cytotoxic effects against cancer cell lines (HCT116, MCF-7) at ≥0.05 mg/mL concentrations. Antimicrobial activity shows MIC/MBC values of 25-50 mg/mL against Staphylococcus aureus.

Safety & Interactions

Mahogany seed extract has been linked to clinically apparent acute liver failure in at least one documented case (Yeap V et al., BMJ Case Rep, 2018; PMID 30061133), and the NCBI LiverTox database classifies it as a potential hepatotoxin. Patients with pre-existing liver disease or those taking hepatotoxic medications should avoid mahogany seed products entirely. Due to its demonstrated hypoglycemic activity, concurrent use with antidiabetic drugs (e.g., metformin, glibenclamide, insulin) may potentiate hypoglycemia and requires medical supervision. While specific CYP450 interaction data remain limited, the high phenolic and limonoid content suggests potential inhibition of CYP3A4 and CYP2C9 enzymes, warranting caution with drugs metabolized through these pathways, including statins, warfarin, and calcium channel blockers.
