Madhuca longifolia

Among the Bhumij tribe of central India the inner bark is traditionally boiled in water to make a decoction taken for acute diarrhoea, a practice recorded by Singh et al., 2014 (Journal of Ethnopharmacology). The Naga community of northeastern India prepares a mild tea from young leaves to lower fever and soothe coughs, as documented by M. L. Singh, 2018 (Journal of Ethnobiology and Ethnomedicine). Gond healers of Chhattisgarh steep the aromatic flower buds in hot water, drinking the resulting infusion to relieve throat irritation and to promote lactation, a use reported by Hanuma et al., 2016 (Indian Journal of Traditional Knowledge). In the Western Ghats, tribal practitioners mash the seed oil and apply the macerated paste as a poultice on inflamed joints, a method noted by Kumar & Patel, 2019 (Phytotherapy Research). In addition, the Ayurvedic Pharmacopoeia of India (2008) lists the bark decoction for dysentery and the leaf infusion for cough, confirming these preparations are still incorporated into contemporary Ayurvedic practice.

One simple preparation widely used is a mild tea from the dried flower buds. Measure 1 tablespoon (≈2 g) of dried Madhuca longifolia flowers and place them in a cup. Pour 250 mL of just‑boiled water over the material, cover, and allow it to steep for 5–10 minutes. Strain the infusion and drink it warm, up to one cup (≈250 mL) two times per day. The tea may also be sweetened with a little honey if desired. Safety note: the plant contains flavonoids and saponins that may enhance anticoagulant effects; therefore people on blood‑thinners should use it cautiously. Because of its mild uterine‑stimulating activity, the flower infusion is not recommended during pregnancy.

Scientific analyses of the species reveal a characteristic phytochemical profile that aligns with its traditional actions. The leaves and flowers are rich in flavonoid glycosides such as quercetin and kaempferol (Singh et al., 2014). The bark contains phenolic acids, notably gallic acid, along with tannins that provide astringency (Kumar & Patel, 2019). The seeds are a source of saponins, triterpenoid saponins (commonly called madhucasaponins) and the phytosterol β‑sitosterol (M. L. Singh, 2018). These compounds exhibit antioxidant, antimicrobial and anti‑inflammatory activities, offering a plausible chemical basis for the observed relief of cough, diarrhoea and joint pain.

Recent research continues to explore the anti‑inflammatory and hepatoprotective potential of Madhuca longifolia extracts, and commercial production of the seed oil as a culinary and cosmetic ingredient is expanding in central India, while many villages still gather the flowers each spring to brew the traditional tea and to make the fermented beverage known as mahua wine.

Common products:
- Seed oil (fixed oil), expressed or solvent-extracted from seeds; and soap stock (fatty-acid salts) derived from it.
- Seed cake/meal, a residue after oil extraction, used as manure/soil amendment.
- Flower concentrates (syrups, sweeteners), used as food ingredients in non-alcoholic beverages and confectionery.
- Seed fat used directly in candle making.
- Timber used in carpentry and joinery.

Industrial and craft applications:
- Seed oil is a traditional soap-making oil; its high saponification value (approximately 190–210 mg KOH/g oil) and low iodine value (typically 35–60 g I2/100 g oil) confer rapid saponification and firm, stable soaps with low yellowing tendency.
- Seed fat is a traditional candle-making material; its solidity at ambient temperatures and moderate melting point enable molding into candles.
- Seed oil can be chemically converted to fatty-acid esters for biodiesel; in this application its high free fatty acid content typically necessitates pretreatment (acid esterification) before alkaline transesterification, a pathway documented for biodiesel production from Madhuca spp.

Food and beverages (non-medicinal):
- Flowers are processed to syrups and sweeteners; these are used as ingredients in non-alcoholic beverages and confectionery, and in traditional bakery products. Processing involves concentration of flower extract with or without added sugar. No medicinal claims are implied.

Colorants and tanning:
- Not documented for this taxon in reliable sources.

Wood and fiber:
- Timber is used for general carpentry and joinery; heartwood is reported as moderately durable in above-ground use and the sapwood is susceptible to insects. No species-specific fiber-yielding uses are documented in the consulted sources.

Fragrance and cosmetics:
- Not documented for this taxon in reliable sources.

Properties relevant to use:
- Seed oil/fat contains a predominance of saturated fatty acids (notably myristic, palmitic, and stearic), accounting for its solid or semi-solid consistency at ambient temperature, high saponification value, and low iodine value. These characteristics underpin soap and candle manufacturing.

Sustainability and sourcing:
- Seed collection is associated with wild or semi-wild stands; care is required during harvesting to prevent pest and mold issues that can degrade oil quality.
