Almost unknown in America, horse chestnut extract is a staple of European herbalism. Horse chestnut is rich in saponins and flavones, which modern research has shown help support the integrity of the vascular system and connective tissue. Planetary Herbals Full Spectrum Horse Chestnut delivers a minimum of 20% aescin, the primary constituent in horse chestnut for assuring potency. Lifestyle Recommendations: To ensure a healthy vascular system, increase dietary intake of flavonoid-rich foods such as buckwheat, yams, onions, grapes and blueberries. Avoid excessive periods of standing or sitting, and exercise regularly. Other Planetary Herbals products for supporting the circulatory system include: Horse Chestnut Vein Strength and Hawthorn Heart.
