CAN cautions that furanocoumarins are phototoxic and may cause dermatosis. 60% antifertility

effects in rats are reported. Conversely, 20%, 40%, and 10% activities were exhibited by aqueous,

alcoholic, and petrol extracts, respectively. Weak estrogenic and antiimplantation activity reported

for seed extracts. Coumarin is a weak estrogen. Excessive doses may interfere with blood pressure,

cardiac, and hormone medications. “In view of the documented estrogenic activity and potentially

toxic irritant volatile oil, excessive doses of wild carrot during pregnancy and lactation should be

avoided” (CAN). Seeds contain psychoactive myristicin (APA). The faces of my granddaughter

and Judi’s daughter, especially their noses, turned orange after eating a full bottle of carrot baby

food. Seed oil LD50 = >5000 mg/kg orl mus, LD50 = >5000 mg/kg der gpg, antispasmodic (^1 / 10 th

papaverine). Cholinergic activity reported for choline, no real surprise there. A 1995 study of carrot

extracts showed that it protected the liver from carbon-tetrachloride damage (APA).
