Earth Dragon was formulated by Ba Hoang M.D., Ph.D., based on the work of three generations of medical doctors versed in western medicine, traditional Chinese medicine (TCM) and the herbal tradition of Vietnam. Earth Dragon is designed to support digestion and assimilation. As a tonic, it supports the digestive function of the stomach and the gastrointestinal tract by balancing the sympathetic and parasympathetic functions of the central nervous system, which can extend benefit to the liver and other organ systems. It may support liver function by enhancing hepatic detoxification and antioxidant activity. For extra support, it is sometimes combined with Colon-Well (Item #74210).
For thousands of years, Lumbricus rubellus, or earthworm powder, has been used for its therapeutic benefits throughout Asia and Southeast Asia, including China, Korea and Vietnam. Earthworms have a dense nutritional content because of their soil-based origin. According to the ancient Chinese medical publication Ben Cao Gang Ma (Compendium of Materia Medica), Lumbricus was said to unblock the body's meridians and channels, and was used to support blood circulation. Lumbricus supports muscle relaxation and tonification of the sympathetic nervous system, potentially benefiting digestion and it also has antioxidant properties.
Atractylodes alba, or bai zhu, is a digestive and liver and gall bladder tonic. In TCM, it is thought to support the functions of the stomach and spleen, the organs responsible for food digestion. Its actions also include detoxification, promotion of the non-specific immune response and nurturing the function of the adrenal cortex.
