Indian Screw Pine Fruit

Indian Screw Pine Fruit (Pandanus odoratissimus) contains flavonoids (quercetin, kaempferol), phenolic acids (gallic acid, caffeic acid), and carotenoids (β-carotene) that scavenge reactive oxygen species via hydrogen atom donation and transition metal chelation, as demonstrated in DPPH, ABTS, and FRAP antioxidant assays. While no dedicated clinical trials are currently indexed on PubMed, extensive ethnobotanical and phytochemical literature from Ayurvedic and Siddha traditions supports its traditional use as a cardiotonic, anti-inflammatory, and digestive aid.

Origin & History

Indian Screw Pine Fruit (Pandanus odoratissimus) is a unique botanical native to the coastal regions, riverbanks, and tropical wetlands of South Asia, particularly India, Sri Lanka, and the Andaman Islands. It is valued in functional nutrition for its adaptogenic, cardiovascular, and skin-supporting properties.

Historical & Cultural Context

- Revered in Ayurvedic and Siddha medicine, Indian Screw Pine Fruit has been traditionally used for hydration, circulation, and longevity. Monks and coastal herbalists utilized it in stress-adaptive, detoxifying, and skin-regenerating formulas alongside other tropical herbs.

Health Benefits

- **Supports cardiovascular function**: by enhancing circulation and reducing oxidative stress.
- **Boosts immune resilience**: through its rich array of polyphenols and carotenoids.
- **Aids stress adaptation**: with its adaptogenic properties, promoting systemic balance.
- **Promotes digestive wellness**: via dietary fiber and soothing compounds.
- **Enhances skin hydration**: and elasticity, contributing to dermal health.
- **Supports metabolic balance**: by modulating lipid profiles and blood sugar.

How It Works

Flavonoids such as quercetin and kaempferol exert antioxidant activity by donating hydrogen atoms from their phenolic hydroxyl groups to neutralize reactive oxygen species (superoxide anion, hydroxyl radical, peroxyl radical) and by chelating pro-oxidant transition metal ions (Fe²⁺, Cu²⁺), thereby interrupting Fenton-reaction-driven lipid peroxidation in cell membranes. Phenolic acids including gallic acid and caffeic acid inhibit lipid peroxidation through similar radical scavenging mechanisms and have been shown to modulate nuclear factor erythroid 2-related factor 2 (Nrf2) signaling, upregulating endogenous antioxidant enzymes such as superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPx). Carotenoids, principally β-carotene, quench singlet oxygen through physical energy transfer and chemical scavenging, protecting polyunsaturated fatty acids in cellular and organellar membranes. Additionally, the dietary fiber fraction may slow glucose absorption in the small intestine by increasing luminal viscosity, potentially modulating postprandial glycemic responses via delayed carbohydrate hydrolysis.

Scientific Research

As of 2024, no dedicated randomized controlled trials on Pandanus odoratissimus fruit are indexed in PubMed, and the current evidence base relies primarily on in vitro phytochemical screening, antioxidant assays, and ethnobotanical documentation. Regional pharmacognosy journals have published studies demonstrating significant DPPH and ABTS radical scavenging activity in methanolic and aqueous extracts of Pandanus species, with IC₅₀ values comparable to ascorbic acid standards in some preparations. Ethnobotanical surveys across South and Southeast Asia consistently document its longstanding use in Ayurveda and Siddha medicine for cardiotonic, anti-inflammatory, diuretic, and aphrodisiac purposes. Further peer-reviewed clinical investigation is needed to validate these traditional claims and establish standardized dosing in human populations.

Clinical Summary

Current evidence is limited to in vitro laboratory studies with no human clinical trials reported. Methanol extracts of P. odoratissimus fruit showed IC50 values comparable to vitamin E in DPPH and thiocyanate assays, though exact numerical values were not specified. Related Pandanus amaryllifolius leaf extract demonstrated IC50 values of 11.96 ± 4.01 μg/ml for DPPH and 26.18 ± 7.44 μg/ml for ABTS radical scavenging. The evidence strength remains preliminary without human validation studies.

Safety & Interactions

No formal toxicological studies or clinical safety trials for Pandanus odoratissimus fruit are currently available in peer-reviewed databases, so definitive safety thresholds and drug interaction profiles have not been established. Given its quercetin and kaempferol content, theoretical interactions exist with CYP3A4- and CYP2C9-metabolized drugs (e.g., warfarin, statins), as these flavonoids are known in vitro inhibitors of these cytochrome P450 isoforms; however, the clinical significance at dietary intake levels remains unquantified. Individuals with known allergies to Pandanaceae species should exercise caution, and pregnant or breastfeeding women should consult a healthcare provider before supplemental use due to the lack of reproductive toxicity data. Traditional preparations consumed as food in South and Southeast Asian cuisines have a long history of apparent safety at culinary doses.
