Celery (Apium graveolens) has been cultivated as a food and used by herbalists for at least 3,000 years. More recently, scientific studies have found that Celery Seed has bioactive compounds that support a healthy inflammatory response. A balanced inflammatory response is known to be important in maintaining healthy circulation and a healthy cardiovascular system. In addition, this product contains Horse Chestnut Seed Extract (Aesculus hippocastanum), which has been shown in clinical studies to support healthy vascular function. Hawthorn Extract has also been included in this 100% vegetarian formula.*
