In Chinese Traditional Medicine, celery is used as a cure for high blood pressure. It is now known that celery contains phytochemical compounds called phthalides, which not only give flavour but have also been shown to lower blood pressure. Studies have shown that celery extract can lower blood cholesterol levels and reduce the formation of the arterial plaques that can result in cardiovascular disease.
Antioxidant celery compounds called coumarins are the focus of much current scientific research due to their potential as anti-cancer substances. Celery is an excellent source of vitamin C, which has anticarcinogenic properties through its role as an antioxidant, and is rich in folate, a vitamin required to make DNA and to prevent pre-cancerous changes to it.
