Parsley health benefits
1. Nutrient rich
Studies show that parsley is rich in nutrients and compounds, including flavonoids and tannins, that have a protective, antioxidant effect.
2. May relieve muscle cramps
One study suggests consuming parsley juice may reduce muscle cramps. This may be useful for sports professionals hoping to support their recovery after training, as well as for females who may experience cramps associated with menstruation.
These effects may be due to mineral content and a phytochemical called apigenin. This appears to induce muscle relaxation and may even ease muscle loss in the elderly.
3. May regulate menstruation
Parsley tea has been used as a natural remedy to help regulate menstruation and balance hormone levels. This is because it contains plant compounds like apiole and myristicin which may stimulate menstrual flow and support hormonal balance.
4. May regulate blood sugar levels
Studies have looked at myricetin, a flavonoid found in parsley, for treatment and prevention of diabetes. Results support that myricetin extract may lower blood sugar levels and decrease insulin resistance.
5. May support a healthy blood pressure
One of the traditional uses of parsley in herbal medicine is to support a healthy blood pressure and cardiovascular system. One study confirmed that parsley extract has a lowering effect on blood pressure, while its high phytochemical content is said to support a healthy heart.
Is parsley safe for everyone?
Parsley appears to be well tolerated, with few major adverse effects recorded. Nevertheless, contact dermatitis and anaphylaxis may occur, and in some cases may relate to cross reactivity with other members of the carrot family, such as celery and fennel.
Parsley and its juice may be problematic for those on prescribed diuretics, blood-thinning medication and anti-diabetes medication. Using parsley at therapeutic doses is likely to be unsafe during pregnancy and during breastfeeding.
Overall, is parsley good for you?
A flavourful addition to your cooking, parsley is highly nutritious and may contribute towards a number of surprising health benefits, from regulating menstruation and hormonal balance to supporting a healthy heart and blood pressure. As a herb, parsley makes a valuable addition to a balanced diet, unless you’re one of the few people who has an allergy.
