Natural Factors Celery Seed Extract Review

The seed of the celery plant has a long history of traditional use among many herbal traditions of the world, including the Unani tradition (ancient Persia and Arabia ) and Ayurveda (India). Modern research has uncovered that much of celery seed’s bioactivity is due to the presence of phytonutrients called phthalides. Of these, 3-n-butylphthalide (3nB) is one of the most well researched. Our Celery Seed Extract is concentrated and standardized to contain 85% 3-n-butylphthalide as total phthalides.
