The Short Answer
Andiroba seed (Carapa guianensis) is rich in gedunin-type limonoids—especially 6α-acetoxygedunin—that suppress inflammation by directly binding myeloid differentiation protein 2 (MD-2) on the TLR4 complex, inhibiting NF-κB signaling and reducing pro-inflammatory cytokines TNF-α and IL-1β, while its oleic- and palmitic-acid-rich oil delivers potent antioxidant, hepatoprotective, and wound-healing activity. A 2024 scoping review in the Journal of Ethnopharmacology (PMID 38432579) confirmed andiroba oil's immunomodulatory and tissue-repair benefits across in vitro, in vivo, and clinical models, and a clinical study (PMID 32920135) demonstrated that topical andiroba oil matched low-power laser therapy in resolving oral mucositis in pediatric chemotherapy patients.

Origin & History
Natural habitat
Andiroba Seed (Carapa guianensis) is derived from a tree native to the Amazon rainforest and other tropical regions of Central and South America. Its seeds are highly valued in functional nutrition for their unique composition of essential fatty acids and limonoids, supporting joint, skin, and immune health.
“Andiroba Seed has been traditionally revered by Amazonian tribes for centuries for wound healing, anti-inflammatory treatments, and spiritual protection rituals. It was also a vital tool in Afro-Brazilian healing baths and massages, and against tropical insect-borne diseases.”Traditional Medicine
Scientific Research
Fonseca et al. (2024) published a comprehensive scoping review in the Journal of Ethnopharmacology covering in vitro, in vivo, and clinical evidence that andiroba oil exerts significant immunomodulatory, anti-inflammatory, and wound-healing effects (PMID 38432579). Soares et al. (2021) conducted a clinical study in pediatric chemotherapy patients showing that topical andiroba oil was as effective as low-power laser therapy for treating oral mucositis, with comparable healing timelines and pain reduction (PMID 32920135). Ninomiya et al. (2016) isolated hepatoprotective limonoids—including gedunin and 6α-acetoxygedunin—from andiroba seeds that protected HepG2 hepatocytes against D-galactosamine/TNF-α-induced cytotoxicity in the International Journal of Molecular Sciences (PMID 27104518). Araujo-Lima et al. (2018) evaluated crabwood seed oils in Oxidative Medicine and Cellular Longevity, confirming robust antioxidant activity via DPPH and ORAC assays alongside a favorable genotoxic safety profile at typical-use concentrations (PMID 29854079).

How It Works
Mechanism of Action
The primary anti-inflammatory mechanism of andiroba seed centers on gedunin-type tetranortriterpenoid limonoids—particularly 6α-acetoxygedunin—which bind directly to myeloid differentiation protein 2 (MD-2) within the TLR4/MD-2 receptor complex, competitively blocking lipopolysaccharide (LPS) recognition and preventing downstream activation of NF-κB signaling, thereby suppressing transcription of pro-inflammatory cytokines TNF-α, IL-1β, and IL-6. Andiroba limonoids also inhibit the phosphorylation of IκBα, stabilizing the NF-κB inhibitory complex in the cytoplasm and attenuating COX-2 and iNOS expression. Hepatoprotective activity is mediated by limonoids that reduce D-galactosamine/TNF-α-induced caspase activation in hepatocytes (PMID 27104518), while the oil's high oleic acid content (~55%) enhances dermal barrier repair and modulates prostaglandin E2 synthesis. Antioxidant defense is supported through radical-scavenging phenolic compounds and tocopherols that neutralize reactive oxygen species and protect cellular lipids from peroxidation (PMID 29854079).
Clinical Evidence
Current evidence is limited to in vitro and animal studies, with no human clinical trials reported. Laboratory studies show 23 isolated limonoids inhibited LPS-induced NO production in RAW264.7 macrophages, with gedunin-type compounds demonstrating superior potency based on IC50 values. Nanoemulsion at 360 μg/mL accelerated keratinocyte migration for wound closure without cytotoxicity in cell culture models. Human clinical data is needed to establish therapeutic efficacy and safety profiles for oral supplementation.
Safety & Interactions
Andiroba seed oil has been used topically and orally in traditional Amazonian medicine with a generally favorable safety profile; Milhomem-Paixão et al. (2016) reported no significant genotoxicity or hematotoxicity in a murine model at standard doses (PMID 27192128), and Araujo-Lima et al. (2018) confirmed a safe genotoxic profile for seed oils at typical concentrations (PMID 29854079). However, there is insufficient clinical data to establish safe oral dosing in humans, and ingestion of large quantities of the bitter oil has been traditionally associated with nausea and gastrointestinal discomfort. No specific CYP450 drug interactions have been formally documented, but given the oil's limonoid content and potential immunomodulatory effects, concurrent use with immunosuppressants, anticoagulants, or anti-inflammatory drugs should be approached with caution and physician guidance. Pregnant and breastfeeding individuals should avoid internal use due to the absence of reproductive safety data.

Frequently Asked Questions
What are the main benefits of andiroba seed oil?
Andiroba seed oil provides potent anti-inflammatory, antioxidant, wound-healing, hepatoprotective, and insect-repellent benefits. A 2024 scoping review (PMID 38432579) confirmed its immunomodulatory and tissue-repair properties across multiple research models. Its high oleic acid content also supports skin hydration, dermal barrier function, and elasticity.
Is andiroba oil safe to use on skin?
Yes, topical application of andiroba oil is generally considered safe and has been used in traditional Amazonian medicine for centuries. A clinical study by Soares et al. (2021, PMID 32920135) applied it topically to pediatric chemotherapy patients' oral mucosa with efficacy comparable to laser therapy and no reported adverse effects. Genotoxicity studies (PMID 29854079) also support its safety at standard topical concentrations.
How does andiroba oil reduce inflammation?
Andiroba's gedunin-type limonoids, especially 6α-acetoxygedunin, bind directly to MD-2 in the TLR4/MD-2 receptor complex, blocking LPS-triggered NF-κB activation and downstream production of TNF-α, IL-1β, and IL-6. This also suppresses COX-2 and iNOS expression, reducing prostaglandin and nitric oxide-mediated inflammation. The mechanism has been validated in multiple in vitro and in vivo models as reviewed by Fonseca et al. (2024, PMID 38432579).
Can andiroba seed oil help with wound healing?
Multiple studies confirm andiroba oil's wound-healing potential. Fonseca et al. (2024, PMID 38432579) documented accelerated tissue repair across in vitro and animal models, while Monteiro et al. (2025, PMID 40284494) developed an andiroba oil-based nanoemulsion that enhanced in vitro healing effects. Its oleic acid promotes dermal cell migration, and limonoids reduce the inflammatory phase of wound repair.
Does andiroba oil have antioxidant properties?
Yes. Araujo-Lima et al. (2018, PMID 29854079) confirmed andiroba seed oil's significant radical-scavenging activity using DPPH and ORAC assays, attributing it to phenolic compounds and tocopherols. Milhomem-Paixão et al. (2016, PMID 27192128) further characterized the lipidome and antioxidant capacity of andiroba oil from the Brazilian Amazon, finding no associated genotoxicity or hematotoxicity, supporting its role in protecting cells from oxidative damage.
Is andiroba seed oil safe to use during pregnancy and breastfeeding?
While andiroba seed oil has a long history of traditional use in indigenous communities, scientific safety data specifically for pregnancy and breastfeeding is limited. It is recommended to consult with a healthcare provider before using andiroba products during pregnancy or while breastfeeding to ensure it is appropriate for your individual situation. Topical use is generally considered safer than internal supplementation during these periods.
How does andiroba seed oil compare to other anti-inflammatory seed oils like neem or coconut oil?
Andiroba seed oil is unique for its high concentration of limonoids and fatty acids that specifically target inflammation and support joint health, whereas neem oil is primarily valued for its antimicrobial and antiparasitic properties. Coconut oil offers different fatty acid profiles and is more commonly used for general skin hydration, while andiroba provides deeper dermal penetration and enhanced wound-healing support. The choice between them depends on whether your primary goal is anti-inflammatory support, antimicrobial action, or basic moisturization.
What does current clinical research show about andiroba seed's antimalarial and antiparasitic effectiveness?
Several laboratory and in vitro studies have demonstrated that compounds in andiroba seed possess antimalarial and antiparasitic properties, though robust human clinical trials remain limited. Traditional use in Amazonian medicine has supported these applications for centuries, but more rigorous clinical research is needed to establish optimal dosing and efficacy in humans. Current evidence suggests andiroba may serve as a complementary approach to conventional treatments, but should not replace proven medical interventions.
