Eriodictyol is a bitter-masking flavanone, a flavonoid extracted from yerba santa (Eriodictyon californicum), a plant native to North America.{{Cite web |last=Kaminski |first=Patricia |last2=Katz |first2=Richard |title=Yerba Santa Eriodictyon californicum |url=http://www.flowersociety.org/Yerba_About.htm |access-date=2022-01-20 |website=Flower Essence Society}} Eriodictyol is one of the four flavanones identified in this plant as having taste-modifying properties, the other three being homoeriodictyol, its sodium salt, and sterubin.{{Cite journal |vauthors=Ley JP, Krammer G, Reinders G, Gatfield IL, Bertram HJ |date=July 2005 |title=Evaluation of bitter masking flavanones from Herba Santa (Eriodictyon californicum (H. and A.)

Eriodictyol has garnered scientific attention for its strong antioxidant, anti-inflammatory, and neuroprotective properties. Structurally similar to other flavonoids, such as hesperidin and naringenin, eriodictyol scavenges free radicals and regulates inflammatory responses.

Eriodictyol was also found in the twigs of Millettia duchesnei,{{Cite journal |display-authors=etal |vauthors=Ngandeu F, Bezabih M, Ngamga D |date=January 2008 |title=Rotenoid derivatives and other constituents of the twigs of Millettia duchesnei |journal=Phytochemistry |volume=69 |issue=1 |pages=258–63 |doi=10.1016/j.phytochem.2007.05.038 |pmid=17640692}} in Eupatorium arnottianum,{{Cite journal |display-authors=etal |vauthors=Clavin M, Gorzalczany S, Macho A |date=July 2007 |title=Anti-inflammatory activity of flavonoids from Eupatorium arnottianum |journal=J Ethnopharmacol |volume=112 |issue=3 |pages=585–9 |doi=10.1016/j.jep.2007.04.007 |pmid=17570627}} and its glycosides (eriocitrin) in lemons and rose hips (Rosa canina).{{Cite journal |last=Hvattum E |year=2002 |title=Determination of phenolic compounds in rose hip (Rosa canina) using liquid chromatography coupled to electrospray ionisation tandem mass spectrometry and diode-array detection |journal=Rapid Commun.
