The Short Answer
Oroxylum indicum seeds are exceptionally rich in the bioactive flavonoids baicalein, chrysin, and oroxylin A, which collectively deliver potent antioxidant radical scavenging, antibacterial, α-glucosidase-inhibitory, anticancer, and antidepressant activities. Zhang et al. (2017) demonstrated that combining these seed-derived flavonoids with acarbose synergistically improved postprandial blood glucose inhibition both in vitro and in vivo (PMID 28511342), while Buranrat et al. (2022) showed the seed extract suppresses cervical cancer cell proliferation and migration while promoting apoptosis (PMID 35642412).

Origin & History
Natural habitat
Oroxylum indicum, commonly known as Midnight Horror Tree or Indian Trumpet Flower, is a deciduous tree native to Southeast Asia, the Indian subcontinent, and China. Its seeds are valued in traditional medicine for their rich array of bioactive compounds that support respiratory, liver, and cognitive health.
“Revered in Ayurveda as a Rasayana, Oroxylum indicum has been traditionally used for rejuvenation and longevity. It was applied for respiratory ailments, liver support, digestive comfort, and wound healing, with the tree symbolizing transformation and resilience in cultural narratives.”Traditional Medicine
Scientific Research
Sithisarn et al. (2016) characterized baicalein, chrysin, and oroxylin A in Oroxylum indicum fruit extracts, demonstrating potent DPPH radical scavenging and significant antibacterial activity against Staphylococcus aureus and Streptococcus intermedius (Molecules; PMID 27070560), with HPLC-quantified follow-up studies in 2019 (PMID 31137493) and 2021 (PMID 33809943) confirming consistent flavone-mediated inhibition of clinically isolated zoonotic bacteria. Zhang et al. (2017) showed that seed-derived flavonoids combined with acarbose synergistically lowered postprandial blood glucose in a mouse model, with individual IC₅₀ values for α-glucosidase inhibition significantly potentiated in combination (Biomed Pharmacother; PMID 28511342). Buranrat et al. (2022) demonstrated that Oroxylum indicum seed extract suppresses cervical cancer cell proliferation and migration while inducing apoptosis in a dose-dependent manner (Pak J Pharm Sci; PMID 35642412). Chalermwongkul et al. (2023) reported that Oroxylum indicum seed extract exerted antidepressant-like effects in a chronic unpredictable mild stress mouse model, modulating neurotransmitter pathways and reducing depressive behaviors (Nutrients; PMID 38004136).

How It Works
Mechanism of Action
Baicalein, chrysin, and oroxylin A competitively inhibit intestinal α-glucosidase—with IC₅₀ values synergistically potentiated when combined with the pharmaceutical inhibitor acarbose—thereby delaying carbohydrate hydrolysis and attenuating postprandial glucose spikes, as validated in vivo by Zhang et al. (2017, PMID 28511342). In cancer models, the seed extract triggers apoptosis via caspase activation and suppresses cell migration by downregulating matrix metalloproteinase pathways, as demonstrated in cervical cancer cell lines (PMID 35642412). The flavonoids also scavenge DPPH and superoxide free radicals by donating hydrogen atoms from their phenolic hydroxyl groups, protecting cellular membranes and DNA from oxidative damage (PMID 27070560; PMID 33809943). Antidepressant-like effects are attributed to modulation of serotonergic and noradrenergic neurotransmission, with chrysin and baicalein known to interact with GABA-A benzodiazepine receptors and inhibit monoamine oxidase activity (PMID 38004136).
Clinical Evidence
Current evidence is limited to preclinical studies with no human clinical trials reported. In diabetic rat models treated for 12 weeks, organic seed extract (400 mg/kg) combined with glibenclamide reduced blood glucose by 79% and total cholesterol by 28%. The same dosage improved liver function markers, reducing SGPT by 8.01% and SGOT by 5.31%. Network pharmacology studies identify 10 active compounds targeting 41 proteins, but human efficacy and safety data are lacking.
Safety & Interactions
Chrysin and baicalein are known inhibitors of CYP1A2 and CYP2C9 in vitro, which could theoretically potentiate the effects of drugs metabolized through these pathways, including warfarin, theophylline, and certain NSAIDs; concomitant use warrants medical supervision. Because the seed flavonoids synergistically enhance acarbose-mediated α-glucosidase inhibition (PMID 28511342), individuals taking antidiabetic medications should monitor for hypoglycemia and consult a healthcare provider before supplementing. No serious adverse effects have been reported in the published animal models at tested dosages, but human clinical safety data remain limited. Pregnant or breastfeeding women, children, and individuals on anticoagulant or antiplatelet therapy should avoid use until human safety trials are completed.

Frequently Asked Questions
What are the main active compounds in oroxylum seeds?
Oroxylum indicum seeds are rich in three principal flavonoids: baicalein, chrysin, and oroxylin A. HPLC analyses across multiple studies (PMID 27070560; PMID 31137493; PMID 41705542) have consistently quantified these as the dominant bioactives responsible for the seed's antioxidant, antibacterial, and enzyme-inhibitory properties.
Can oroxylum seeds help lower blood sugar levels?
Yes, preclinical evidence supports this benefit. Zhang et al. (2017) demonstrated that baicalein, chrysin, and oroxylin A from the seeds competitively inhibit α-glucosidase, and when combined with acarbose, they synergistically reduce postprandial blood glucose in mice (PMID 28511342). However, human clinical trials are still needed to confirm dosing and efficacy.
Do oroxylum seeds have anticancer properties?
Buranrat et al. (2022) showed that Oroxylum indicum seed extract suppresses proliferation and migration of cervical cancer cells (HeLa) in vitro while promoting apoptosis in a dose-dependent manner (PMID 35642412). These results are promising but are limited to cell culture models, and human clinical studies have not yet been conducted.
Are oroxylum seeds used for mental health or depression?
Chalermwongkul et al. (2023) reported that Oroxylum indicum seed extract exerted significant antidepressant-like effects in mice subjected to unpredictable chronic mild stress, potentially by modulating serotonergic and noradrenergic neurotransmission (PMID 38004136). Chrysin and baicalein in the seeds are also known to interact with GABA-A receptors, contributing to anxiolytic and mood-regulating effects.
What antibacterial properties do oroxylum seeds have?
Multiple studies by Sithisarn and colleagues (2016, 2019, 2021) demonstrated that flavone-rich extracts from Oroxylum indicum exhibit significant antibacterial activity against Staphylococcus aureus, Streptococcus intermedius, and other clinically isolated zoonotic bacteria (PMID 27070560; PMID 31137493; PMID 33809943). A 2024 follow-up study further validated these effects in an ointment formulation tested on dog wound healing (PMID 39290547).
Is oroxylum seed safe to take with common medications like blood pressure or thyroid medications?
Oroxylum seeds contain bioactive flavonoids that may interact with certain medications, particularly those metabolized by the liver such as antihypertensives and thyroid medications. It is essential to consult with a healthcare provider before combining oroxylum seed supplements with prescription drugs to avoid potential adverse effects or reduced medication efficacy. The hepatoprotective properties that make oroxylum beneficial can also influence drug metabolism pathways.
What is the recommended dosage of oroxylum seed, and when should I take it?
Typical oroxylum seed supplementation ranges from 250–500 mg per day in standardized extract form, though optimal dosing may vary based on individual health status and product concentration. It is generally best taken with meals to enhance absorption and minimize potential gastrointestinal discomfort, and consistent daily intake is recommended for cumulative benefits to respiratory, liver, and immune function. Always follow the manufacturer's label instructions or consult a healthcare practitioner for personalized dosing guidance.
What does clinical research show about oroxylum seed's effectiveness for respiratory health?
Scientific studies have demonstrated that oroxylum seed's anti-inflammatory and bronchodilatory compounds help reduce airway inflammation and support normal respiratory function, particularly in traditional Ayurvedic formulations. Research indicates that the seed's flavonoid and lignin content contributes to these respiratory benefits through mechanisms that reduce mucus production and promote airway relaxation. However, most evidence comes from in vitro and animal studies, with limited large-scale human clinical trials, suggesting a need for further research to establish definitive efficacy in respiratory conditions.
