Parsnip (Pastinaca sativa) is a sweet, starch-rich root vegetable that contains high levels of potassium, soluble and insoluble fiber, and active furanocoumarins. Potassium promotes vasodilation and stimulates renal flushing, assisting in the excretion of excess sodium and water to support blood pressure health. Its abundant soluble fiber provides excellent prebiotic food for a healthy gut microbiome, supporting optimal digestion.

Generally safe as food. Wild parsnip foliage contains furanocoumarins that can cause severe phytophotodermatitis (blistering skin reactions under sunlight) when handled; ensure you handle culinary roots or wear gloves if harvesting wild plants. Avoid therapeutic medicinal doses if on prescription diuretics.
