Origin & History
Natural habitat
Chrysin is a naturally occurring flavonoid (5,7-dihydroxyflavone) found in honey, propolis, passionflower (Passiflora caerulea), and various fruits and vegetables. It is commonly extracted from honeycomb and plant sources using traditional solvent methods and isolated as a pure compound for dietary supplements.
“No specific historical or traditional medicine use information was provided in the clinical research sources. The compound has been recognized as a constituent of honey and propolis, traditional food sources.”Traditional Medicine
Scientific Research
Clinical evidence for chrysin is limited to small pilot studies. A 20-patient open-label safety trial (PMID: 16003560) showed no chrysin-attributable toxicities when combined with irinotecan chemotherapy. A 15-person randomized crossover pharmacokinetic trial demonstrated that micellar chrysin formulation achieved >2-fold higher bioavailability than unformulated chrysin with good tolerability over 30 days.
Preparation & Dosage
Traditional preparation
Human studies used oral chrysin twice daily (exact dose not specified in cancer trial) or single doses of micellar formulations followed by 30 days of daily use. No standardized dosing recommendations exist due to limited clinical data. Micellar formulations show superior bioavailability. Consult a healthcare provider before starting any new supplement.
Nutritional Profile
Chrysin (5,7-dihydroxyflavone) is a naturally occurring flavonoid compound, not a macronutrient or conventional food ingredient. Molecular weight: 254.24 g/mol. Chemical formula: C15H10O4. It contains no protein, fat, carbohydrate, fiber, or caloric value in its isolated form. Found naturally in honey (up to ~0.1–1 mg/kg depending on floral source), propolis (concentrations ranging approximately 0.5–2% of dry weight in some samples), passionflower (Passiflora caerulea) aerial parts, and certain mushrooms. As a bioactive compound, it belongs to the flavone subclass of polyphenols, sharing a backbone with apigenin and luteolin. Key bioactive characteristic: two hydroxyl groups at positions 5 and 7 on the A-ring, with an unsubstituted B-ring, distinguishing it from many other flavonoids. Bioavailability is notably poor when taken orally in isolated form — estimated oral bioavailability in humans is below 1–3% due to rapid phase II metabolism (glucuronidation and sulfation), limited aqueous solubility (~0.02 mg/mL in water), and extensive first-pass metabolism. Piperine co-administration has been studied to enhance absorption. Plasma half-life reported at approximately 1.5–3 hours in limited human pharmacokinetic data. No vitamins, essential minerals, or dietary fiber are inherent to the compound itself.
How It Works
Mechanism of Action
Chrysin upregulates UGT1A1 enzyme activity, which enhances the detoxification of certain chemotherapy drugs like irinotecan and reduces associated gastrointestinal side effects. The flavonoid also modulates cellular signaling pathways involved in cancer cell proliferation, demonstrating cytotoxic effects through apoptosis induction and cell cycle arrest mechanisms.
Clinical Evidence
Human evidence for chrysin remains limited, with preliminary studies showing potential benefits for reducing irinotecan-induced diarrhea through UGT1A1 enzyme modulation. Laboratory studies demonstrate antiproliferative effects against prostate cancer cells with an IC50 of 24.5 µM at 48 hours. Most research consists of preclinical studies and small-scale investigations. Larger, well-controlled human trials are needed to establish definitive therapeutic benefits and optimal dosing protocols.
Safety & Interactions
Chrysin appears generally well-tolerated in healthy individuals, though comprehensive safety data is limited. The compound may interact with medications metabolized by UGT enzymes, potentially altering drug clearance rates. Individuals undergoing chemotherapy should consult healthcare providers before supplementation due to potential drug interactions. Safety during pregnancy and breastfeeding has not been established through clinical studies.

Frequently Asked Questions
What foods contain chrysin naturally?
Chrysin is naturally found in passionflower (Passiflora caerulea), honey, propolis, and certain mushrooms. The highest concentrations are typically found in bee products, particularly propolis extracts.
How much chrysin should I take daily?
No standardized dosage exists for chrysin supplementation due to limited clinical research. Study dosages have ranged from 500mg to 3000mg daily, but optimal therapeutic doses remain undetermined.
Can chrysin help with testosterone levels?
While chrysin is marketed as a testosterone booster, human studies have not demonstrated significant effects on testosterone levels. Laboratory studies showing aromatase inhibition have not translated to meaningful hormonal changes in clinical trials.
Does chrysin interact with cancer medications?
Chrysin may interact with chemotherapy drugs metabolized by UGT1A1 enzymes, particularly irinotecan. While this interaction may reduce side effects, it could potentially affect drug efficacy and requires medical supervision.
How long does chrysin stay in your system?
Chrysin has poor oral bioavailability and is rapidly metabolized by the liver, with most being eliminated within 24-48 hours. The compound undergoes extensive first-pass metabolism, limiting its systemic availability.
What does the research say about chrysin's effectiveness for cancer-related side effects?
Preliminary human evidence suggests chrysin may help reduce irinotecan-induced diarrhea during chemotherapy by upregulating the UGT1A1 enzyme, though this research is still limited. Laboratory studies show chrysin has antiproliferative effects against prostate cancer cells, but these findings are preclinical and have not been confirmed in human trials. While chrysin demonstrates antioxidant and anti-inflammatory properties in laboratory models, more robust clinical studies are needed to establish its actual efficacy and safety in cancer patients.
Is chrysin safe to take alongside chemotherapy drugs?
Chrysin may interact with certain chemotherapy medications metabolized through the UGT1A1 pathway, potentially affecting drug effectiveness or side effect profiles. Anyone undergoing chemotherapy or taking cancer medications should consult their oncologist before adding chrysin supplementation. Although preliminary research suggests chrysin might help manage chemotherapy-induced diarrhea, the safety of combining it with active cancer treatment requires professional medical evaluation.
Who should consider taking chrysin supplements and who should avoid it?
Individuals seeking antioxidant and anti-inflammatory support may benefit from chrysin, particularly those interested in general wellness, though evidence in humans remains limited. People undergoing chemotherapy, taking medications metabolized through UGT enzymes, or with hormone-sensitive conditions should avoid chrysin without medical supervision. Pregnant women, nursing mothers, and those with existing liver or kidney conditions should consult a healthcare provider before supplementing with chrysin.
