It’s not complicated: take care of your liver and kidneys and they’ll take care of you. Adding Swanson Eucommia Bark to your daily routine is a great way to start. The liver and kidneys serve as the body’s primary detoxifying organs, which makes their day-to-day care central to both your mental and physical wellbeing. And eucommia bark can play a valuable role in that. Although it may not be very well known in the West, eucommia has long been famous in Asia as one of the 50 fundamental herbs of Chinese herbology, prized for centuries as a “yang” tonic for liver and kidney support.
