Where Does It Come From? (5)

Diosmetin is a naturally occurring flavonoid (flavone), found in Rosemary, Hyssop, Citrus fruits and 2 other sources. It is well tolerated orally (low toxicity).

Research & Evidence

Diosmetin is a methoxylated flavone and the aglycone of the glycoside diosmin. It occurs in a range of aromatic herbs, including rosemary and hyssop, and in citrus. Like related dietary flavonoids it has been examined in laboratory studies for antioxidant and other bioactivities, but well-defined clinical roles for the isolated compound are limited.

Toxicity & Safety

As a minor flavonoid of common culinary herbs and fruits, dietary exposure to diosmetin is generally regarded as low risk; its isolated safety profile has not been extensively characterised.
