Hej
Jeg ved dette er en meget gammel tråd men har selv brugt noget tid på at undersøge emnet og har endlig fundet noget information.
www.extension.umn.edu/agriculture/ horse/pasture/wild-parsnip/
Her kan man finde denne information om planten:
Toxin: Wild parsnip may contain chemicals called furanocoumarins.
When Toxic: All growth stages of the plant, when eaten fresh or dried in hay. High concentrations of furanocoumarins have been founds in the seeds as well.
Toxicity: The toxic dose of wild parsnip is not known. The toxic dose of other plants known to accumulate furanocoumarins has not been established either.
Signs and Effects of Toxicosis: Severe sunburn (photosensitivity) occurs in people and animals ingesting furanocoumarins if they are exposed to UV light after ingestion. Sunburn occurs after ingestion due to the furanocoumarin circulation in the blood vessels just below the skin. The UV light exposure is almost always from the sun. Severe sunburn occurs on the white or other light skinned areas, but not the black, brown, or other dark skinned areas, because melanin in the dark skin absorbs the UV light and prevents it from reacting with the furanocoumarins. Consequently, severe sunburn in livestock ingesting furanocoumarin-containing plants is reduced if the livestock are shaded from the ultraviolet sunlight.
