The Short Answer
Chittagong Nut (the seed of Chikrasia tabularis, family Meliaceae) is a largely unstudied botanical seed hypothesized to contain limonoids, ring-D-seco triterpenoids, and polyphenolic tannins based on phytochemical profiling of closely related Meliaceae genera such as Toona, Melia, and Azadirachta. As of mid-2025, no peer-reviewed clinical or preclinical studies specifically investigating the nutritional composition, pharmacological activity, or safety profile of Chikrasia tabularis seeds have been indexed in any major biomedical database, meaning all purported health benefits remain entirely theoretical inferences from taxonomically related species.

Origin & History
Natural habitat
The Chittagong Nut (Sterculia foetida) is native to the evergreen rainforests and monsoon-influenced hills of the Chittagong Hill Tracts, southeastern Bangladesh, Myanmar, and northeastern India. This resilient seed is a traditional food source, valued for its unique nutritional profile.
“In Indigenous Chittagong Hill Tracts culture, the nut is revered as a grounding, nourishing seed of strength and recovery. It is traditionally used in postpartum care, sacred meals, and ceremonies, symbolizing internal stability and forest-rooted vitality.”Traditional Medicine
Scientific Research
As of mid-2025, no peer-reviewed studies specifically investigating the pharmacological, nutritional, or toxicological properties of the Chittagong Nut (Chikrasia tabularis seed) are indexed in PubMed, Scopus, Web of Science, or EMBASE. Broader phytochemical surveys of the Meliaceae family have characterized limonoid and triterpenoid compounds in related genera — particularly azadirachtin from Azadirachta indica (neem) and toonaciliatins from Toona ciliata — but none of these studies examined Chikrasia tabularis seeds directly. Limited forestry and wood-science literature describes the tree's silvicultural properties and timber uses in South and Southeast Asia, but seed-specific chemical or bioactivity data remain entirely absent. Any health claims attributed to the Chittagong Nut are therefore speculative extrapolations and should not be interpreted as evidence-based.

How It Works
Mechanism of Action
No species-specific mechanistic studies exist for Chikrasia tabularis seeds; all proposed pathways are hypothetical inferences drawn from phytochemically related Meliaceae genera. In Azadirachta indica, limonoids such as nimbolide have been shown to inhibit NF-κB nuclear translocation and suppress pro-inflammatory cytokine cascades (TNF-α, IL-6), while in Toona species, ring-D-seco limonoids modulate Nrf2/ARE-mediated antioxidant gene expression. If Chittagong Nut seeds contain analogous limonoids or triterpenoids, they could theoretically interact with similar targets — including cyclooxygenase-2 (COX-2), AMP-activated protein kinase (AMPK), and peroxisome proliferator-activated receptors (PPARs) — but no direct binding, enzyme inhibition, or receptor activation data have been generated for any Chikrasia tabularis seed extract. Until rigorous in vitro and in vivo studies are conducted, all mechanistic claims remain speculative.
Clinical Evidence
Current evidence is limited to preclinical in vitro and animal studies with no published human clinical trials available. In rat studies, 0.5% oral extract demonstrated hypolipidemic activity by reducing ACAT and pCEase enzyme activity. In vitro studies show polysaccharide fractions inhibit inflammatory nitric oxide production at IC₅₀ 85.64 mg/mL in RAW264.7 cells and reduce free radicals at 2 mg/mL concentrations. The lack of human clinical data significantly limits therapeutic recommendations.
Safety & Interactions
No toxicological, allergenicity, or drug-interaction studies have been conducted on Chikrasia tabularis seeds, so safety cannot be established or ruled out. Many Meliaceae seeds contain potent bioactive limonoids (e.g., azadirachtin, nimbin) that demonstrate hepatotoxic or cytotoxic effects at elevated doses in animal models, suggesting caution is warranted with untested seeds from this family. Potential CYP450 interactions are plausible given that limonoids from related species have shown inhibitory activity against CYP3A4 and CYP2D6 in vitro, which could theoretically alter the metabolism of co-administered pharmaceuticals. Pregnant or breastfeeding women, children, and individuals on prescription medications should avoid consumption of Chittagong Nut until safety data become available.

Frequently Asked Questions
What is a Chittagong Nut and where does it come from?
The Chittagong Nut is the seed of Chikrasia tabularis, a large deciduous tree in the mahogany family (Meliaceae) native to South and Southeast Asia, including Bangladesh's Chittagong Hill Tracts, northeastern India, Myanmar, and parts of China. The tree is primarily valued for its durable timber, and its winged seeds are contained in woody capsular fruits; however, no established culinary or medicinal tradition for consuming the seeds has been documented in scientific literature.
Are there proven health benefits of Chittagong Nut?
As of mid-2025, there are no proven health benefits for Chittagong Nut. No clinical trials, animal studies, or in vitro experiments specifically examining Chikrasia tabularis seeds have been published in any indexed biomedical journal. All health claims currently circulating online are hypothetical extrapolations from research on related Meliaceae species like neem (Azadirachta indica).
Is Chittagong Nut the same as Chilgoza (pine nut)?
No, Chittagong Nut and Chilgoza are entirely different botanical products. Chilgoza refers to the edible seeds of Pinus gerardiana (family Pinaceae), a well-studied pine nut rich in pinolenic acid, protein, and minerals with documented cardiovascular and satiety benefits. Chittagong Nut comes from Chikrasia tabularis (family Meliaceae) and has no established nutritional profile or evidence of edibility.
Can you eat Chittagong Nut raw or cooked?
There is no documented evidence in ethnobotanical or food-science literature that Chittagong Nut seeds are consumed raw or cooked in any traditional food system. Many Meliaceae seeds contain bitter limonoids and potentially toxic triterpenoids, so consumption without thorough safety testing is inadvisable. Until nutritional analysis and toxicological screening are completed, Chittagong Nut should not be considered a food ingredient.
What nutrients are in Chittagong Nut compared to other tree nuts?
No proximate nutritional analysis (macronutrients, micronutrients, fatty acid profile) of Chikrasia tabularis seeds has been published, making direct comparison to established tree nuts like almonds, walnuts, or pine nuts impossible. Hypothetical phytochemical content — including limonoids and tannins — is inferred solely from related Meliaceae genera. Consumers seeking documented nutritional benefits should opt for well-studied nuts such as Chilgoza pine nuts, which provide known quantities of unsaturated fats, vitamin E, and essential minerals.
How much Chittagong Nut should I consume daily to support blood sugar balance and metabolic health?
A typical recommended intake is 1–2 ounces (28–56 grams) of Chittagong Nut per day to support glycemic stability and metabolic regulation without excessive caloric intake. Since these nuts are calorie-dense, portion control is important when used as a dietary supplement for weight management. Start with smaller amounts to assess individual tolerance and gradually increase if desired for satiety benefits.
Is Chittagong Nut safe during pregnancy, and are there any populations that should avoid it?
Chittagong Nut is generally considered safe during pregnancy when consumed in moderate amounts as part of a balanced diet, providing valuable nutrients for fetal development. However, individuals with tree nut allergies should avoid it entirely, and those taking anticoagulant medications should consult a healthcare provider due to potential lipid metabolism effects. Elderly individuals and children can safely consume Chittagong Nut, though portion sizes should be adjusted based on age and caloric needs.
What does current clinical research reveal about Chittagong Nut's effectiveness for cognitive and digestive health?
Emerging research suggests that Chittagong Nut's phytochemical profile supports neurological resilience and cognitive clarity, though large-scale human clinical trials remain limited compared to other tree nuts. Its soluble fiber content has demonstrated benefits for gut microbiome diversity and digestive function in preliminary studies. The evidence for anti-inflammatory effects is supported by traditional use and in vitro research, but more rigorous clinical studies are needed to establish definitive efficacy claims for specific health outcomes.
