Availability
Swietenia mahagoni is native to the Caribbean bioregion, including islands like the Bahamas, Cuba, Jamaica, Hispaniola, and southern Florida. However, due to historic over-harvesting for its prized timber, supplies from its native range are rare, and the species is classified as Near Threatened by the IUCN, and protected under CITES Appendix II (regulating trade of its timber). Cultivation: It is widely cultivated as a plantation tree in tropical regions outside its native range, including parts of tropical Asia (e.g., India, Indonesia, Malaysia) and Africa, where it has become naturalized or even invasive in some locations. Much of the mahogany wood traded today comes from these plantations or from the related species, Swietenia macrophylla. Medicinal Availability: The plant parts (especially seeds, bark, and leaves) used for traditional medicine are primarily available locally in the regions where the tree is grown and used in folk remedies. Commercial preparations of the seeds, sometimes called "Sky Fruit" (referencing the fruit's upwards growth), are available as powders, capsules, or extracts, often marketed for conditions like diabetes and hypertension.
External Look
Swietenia mahagoni is a medium to large semi-evergreen tree: Size: It typically grows to a height of 25–35 meters (98–115 ft), with a trunk that can reach up to 4 meters across. Bark: The bark is deeply fissured, starting as smooth grey when young, and maturing to a reddish-brown and scaly texture. Leaves: Leaves are alternate and pinnate, about 12–25 cm long. They have about 4 to 8 pairs of leaflets. The leaflets are oblong-lanceolate, leathery, with an oblique base and an acuminate (tapering to a point) apex. Flowers: The flowers are small, greenish-yellow, with five petals, borne on panicles (branched clusters) up to 10 cm long. Fruit (Capsule): The fruit is a distinct, woody, oblong to pear-shaped, brown capsule, about 7 x 5.5 cm, which splits open into five parts upon maturity. These fruits are sometimes called "sky fruit" because of their tendency to hang upwards. Seeds: The capsule contains numerous winged seeds, ca 6 x 1.5 cm, which are released when the fruit splits.
Healing Properties
The tree exhibits a wide range of properties supported by traditional use and some scientific studies: Antidiabetic: Seed extracts have been studied for their ability to significantly reduce blood glucose levels. Antimalarial/Febrifuge: Historically, the bark decoction is a well-known remedy for fever (febrifuge) and is used against malaria. Antihypertensive: Seed extracts have shown potential to lower blood pressure in animal models, possibly by containing compounds that affect blood vessel relaxation. Antimicrobial/Antiseptic: Extracts from the bark and seeds show inhibitory effects against various bacteria and fungi. Bark decoction is traditionally applied to wounds as an antiseptic. Antidiarrheal/Gastroprotective: The astringent bark is used traditionally for diarrhea and dysentery. Seed extracts have shown anti-ulcerogenic and gastroprotective activity. Antioxidant: Various extracts, particularly from the seeds and leaves, possess strong antioxidant potential, helping to protect cells from free radical damage. Anti-inflammatory: Compounds isolated from the bark and seeds show potent anti-inflammatory activity. Astringent: The bark is astringent, useful for tightening tissues and often applied to wounds or taken internally for diarrhea. Aphrodisiac/Tonic: The bark infusion is traditionally used as a general tonic and an aphrodisiac in some cultures.
Advantages
Natural Remedy for Chronic Conditions: Offers a traditional option for managing widespread conditions like diabetes and hypertension, which are often costly to treat with conventional medicine. Broad Spectrum of Activity: Its anti-inflammatory, antimicrobial, and antioxidant properties make it useful for a variety of ailments, from wound healing to chronic diseases. Source of Valuable Timber: The wood is one of the world's most desired hardwoods, providing significant economic value where sustainably harvested. Phytochemical Richness: Contains a diverse array of bioactive compounds, particularly limonoids, that are of high interest for pharmaceutical development.
Uses
Different parts of Swietenia mahagoni have varied uses: Bark: Internal: Decoction used as a febrifuge (for fever), bitter tonic, and astringent for catarrh, diarrhea, dysentery, and anemia. In larger doses, historically used as an abortifacient (use with extreme caution, as reported in folk medicine). External: Decoction or infusion applied as an antiseptic and astringent to dress wounds and stop bleeding. Seeds: Internal: Seed powder or extracts are used as an antidiabetic and to treat hypertension, malaria, chest pain, and to increase appetite. Consumption of seeds is reported to be potentially harmful in some reports and should be approached with caution. External: Paste from seeds is applied for leucorrhea. Leaves: Decoction is used for nervous disorders. Leaf and root used as an emollient for bleeding.

Using way
Traditional methods of preparation and use include: Decoction of Bark: Bark is boiled in water to create a decoction. This is then strained and consumed for internal uses like fever, diarrhea, and as a tonic, or cooled and applied externally as a wash for wounds. The dosage should be small and carefully monitored, especially for internal use, due to the presence of potent compounds. Infusion of Bark or Root: Bark or root is steeped in hot water (or sometimes alcohol like rum) to create an infusion or tonic. This is traditionally used for gonorrhea (mixed with other herbs), as a tonic, or as an aphrodisiac. Seed Powder/Extracts: The seed is often dried, crushed into a powder, or used to prepare extracts (e.g., ethanolic, aqueous) for oral consumption to manage diabetes or hypertension. Due to the high potency and potential toxicity concerns, processed, standardized extracts, often in capsule or tablet form, are safer than consuming raw seeds. Paste from Seeds/Young Shoots: Crushed seeds or the juice from young shoots is applied topically to the skin for conditions like leucorrhea, bleeding, or as a wound healer. Note: Consultation with a qualified healthcare professional and adhering to scientifically validated dosages is crucial, as the consumption of seeds, in particular, may carry risks.
Conclusion
