Rigorous Scientific Testing

Founded by traditional Chinese medicine practitioners, Nuherbs® respectfully follows the tradition of the herbs and their intended uses. With the aid of modern technology and skilled lab technicians, we are now able to quantify the herbal knowledge that has been passed down for centuries. With changes in weather patterns and other agricultural practices, such as increase use of pesticides and fertilizers, the growth and life of the herbs have been directly impacted. Herbs that appear potent may actually have very low levels of active constituents. Therefore, it is increasingly important and necessary to verify the quality and safety of these herbs to ensure that they are fit for use. Our rigorous scientific testing program is designed to provide relevant insights that are essential to the quality of your products, and thus to your success.
