The Short Answer
Pinocembrin is a dihydroflavonone compound found in honey, propolis, and certain plants that exhibits neuroprotective properties through antioxidant mechanisms. It modulates apoptotic pathways by inhibiting p53 expression and regulating Bax-Bcl-2 ratios in preclinical studies.

Origin & History
Natural habitat
Pinocembrin is a flavanone flavonoid (5,7-dihydroxyflavanone) found naturally in diverse plants including Pinus heartwood, Eucalyptus, propolis, honey, fruits, vegetables, nuts, seeds, herbs, and spices. It is purified using chromatographic techniques or biosynthesized in microbes like E. coli using enzymes such as phenylalanine ammonia-lyase (PAL) and chalcone synthase (CHS).
“While pinocembrin is found in plants like damiana (Turnera diffusa) and yerba santa (Eriodictyon californicum) that have ethnobotanical associations, no specific traditional medicine uses or historical context for pinocembrin itself are documented in the research. The compound has general chemopreventive associations but lacks explicit traditional claims.”Traditional Medicine
Scientific Research
No human clinical trials, randomized controlled trials (RCTs), or meta-analyses have been conducted on pinocembrin according to available research. All current evidence is limited to preclinical studies using in vitro and animal models, particularly focused on neuroprotection in cerebral ischemia and glutamate injury models.
Preparation & Dosage
Traditional preparation
No clinically studied dosage ranges, forms, or standardization details are available as no human trials have been conducted. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Pinocembrin (5,7-dihydroxyflavanone) is a flavanone with molecular weight ~256.25 g/mol, not a nutritional food source but a bioactive polyphenolic compound. Found naturally in propolis (concentrations ~10-30 mg/g of propolis extract), honey (trace amounts, ~0.5-5 mg/kg), ginger rhizomes, and various plant resins. As a flavanone, it contains two hydroxyl groups at positions 5 and 7 on the A-ring, responsible for its antioxidant capacity (ORAC values comparable to other dihydroxylated flavonoids). Bioavailability is relatively low due to rapid Phase II metabolism (glucuronidation and sulfation in the gut and liver); oral bioavailability estimated at ~3-5% in rodent models. Lipophilic character (LogP ~2.6) allows moderate membrane permeability and notable blood-brain barrier penetration, which underlies its neuroprotective research interest. No significant macronutrient, vitamin, or mineral content as it is consumed as an isolated compound or within propolis extracts, typically dosed at 10-100 mg in supplement form.
How It Works
Mechanism of Action
Pinocembrin exerts neuroprotective effects by scavenging reactive oxygen species and reducing oxidative stress in neural tissues. It inhibits p53-mediated apoptosis while modulating the Bax-Bcl-2 protein ratio to prevent programmed cell death. The compound also demonstrates anti-inflammatory activity through inhibition of pro-inflammatory cytokine release.
Clinical Evidence
Current evidence for pinocembrin comes primarily from in vitro laboratory studies and animal models of cerebral ischemia-reperfusion injury. Preclinical studies have shown neuroprotective effects in rodent stroke models, but no human clinical trials have been conducted. The antioxidant activity has been demonstrated in cell culture studies using various oxidative stress markers. Evidence remains limited to preliminary research without human validation of therapeutic benefits.
Safety & Interactions
Safety data for pinocembrin supplementation in humans is extremely limited due to lack of clinical trials. No specific drug interactions have been documented, though theoretical interactions with anticoagulant medications may exist given its presence in propolis. Pregnant and breastfeeding women should avoid pinocembrin supplements due to insufficient safety data. Individuals with bee product allergies should exercise caution as pinocembrin is naturally found in honey and propolis.

Frequently Asked Questions
What foods contain pinocembrin naturally?
Pinocembrin is naturally found in honey, bee propolis, and certain plants including fingerroot (Boesenbergia rotunda) and some Eucalyptus species. Honey and propolis represent the most concentrated natural sources of this flavonoid compound.
How much pinocembrin should I take daily?
No established dosage recommendations exist for pinocembrin supplements as human clinical trials have not been conducted. Preclinical studies have used doses ranging from 5-50 mg/kg in animal models, but this cannot be directly translated to human dosing.
Can pinocembrin help with stroke recovery?
Pinocembrin has shown neuroprotective effects in animal models of stroke and cerebral ischemia-reperfusion injury. However, no human clinical trials have validated these benefits for stroke recovery, so evidence remains limited to preclinical research.
Is pinocembrin the same as other flavonoids?
Pinocembrin is a specific dihydroflavonone that differs structurally from other flavonoids like quercetin or catechins. While it shares general antioxidant properties with other flavonoids, pinocembrin has unique molecular characteristics and specific p53 inhibition mechanisms.
Are there any side effects of pinocembrin supplements?
No specific side effects have been documented for pinocembrin supplements in humans due to lack of clinical studies. Potential allergic reactions may occur in individuals sensitive to bee products, since pinocembrin is naturally present in honey and propolis.
What does clinical research show about pinocembrin's effectiveness in humans?
Most evidence for pinocembrin comes from laboratory and animal studies, with limited human clinical trials to date. While preclinical research demonstrates neuroprotective and antioxidant properties in cell and rodent models, these findings have not yet been reliably translated to proven human benefits. More rigorous clinical studies are needed to establish safety and efficacy in human populations before definitive health claims can be made.
Does pinocembrin interact with common medications?
There is insufficient clinical data to establish specific drug interactions with pinocembrin in humans. As a flavonoid compound, it may theoretically interact with medications metabolized through cytochrome P450 enzymes or anticoagulants, though these interactions have not been formally studied. Individuals taking prescription medications should consult a healthcare provider before adding pinocembrin supplements to ensure safety.
Is pinocembrin safe for pregnancy and nursing?
There are no adequate safety studies on pinocembrin use during pregnancy or lactation, so it is generally not recommended during these periods. The lack of human clinical data means potential risks to fetal development or infant health cannot be ruled out. Pregnant and nursing women should avoid pinocembrin supplements unless explicitly advised by their healthcare provider.
