Heat-Draining Herbs
In a healthy dog, the heart, a fire element (yang), and the kidney, a water element (yin), are balanced. Excessive emotional or physical stress and aging can diminish normal kidney function, which leads to the inability to control heat (heart fire) and subsequently allows nervousness to occur. Rehmannia, asparagus tuber, ophiopogon, and scrophularia all help to clear heat and restore balance.
