The properties of Parsley
Parsley is a source of flavonoids and antioxidants, especially luteolin, apigenin, folate, vitamin K, vitamin C, and vitamin A. Half a tablespoon (a gram) of dried parsley contains about 6.0 µg of lycopene and 10.7 µg of alpha carotene as well as 82.9 µg of lutein+zeaxanthin and 80.7 µg of beta carotene. Dried parsley can contain about 45 mg/gram apigenin. The apigenin content of fresh parsley is reportedly 215.5 mg/100 grams, which is much higher than the next highest food source, green celery hearts providing 19.1 mg/100 grams.
Excessive consumption of parsley should be avoided by pregnant women. Normal food quantities are safe for pregnant women, but consuming excessively large amounts may have uterotonic effects.
