Our Kidney Tonic features astragalus root (Astragalus membranaceus) as a key component of the formula, offering valuable kidney support for dogs and cats. This herb provides antioxidant protection and anti-inflammatory benefits, and its ability to help reduce proteinuria (elevated protein in urine) in animals with kidney disease is particularly noteworthy. Astragalus membranaceus root is generally safe for pets and is commonly used in natural kidney supplements for pets to support their immune system. However, it's important to note that other Astragalus species, such as Astragalus anemophilus, Astragalus pseudozagrosicus, and Astragalus monspessulanus, contain toxic compounds in their leaves and roots. While "toxic" may sound alarming, it often refers to large quantities above normal ingestion levels, with symptoms like nausea and vomiting that resolve when the herb is discontinued. Very few herbs are truly toxic to animals, and these are not sold commercially for use in herbal remedies or supplements.
