Kidney function is essential for detoxifying the blood, balancing minerals, and regulating blood pressure through hormone production and fluid management. Healthy kidney function ensures the removal of waste products via urine and supports critical processes like acid-base balance. Herbs like nettle (Urtica dioica), dandelion leaf (Taraxacum officinale), and parsley (Petroselinum crispum) are often used to support kidney health and promote optimal function. Maintaining proper hydration and avoiding toxins are key factors in sustaining kidney function.
