Panax pseudoginseng, also known as "Tienchi ginseng," is traditionally used in Chinese medicine primarily for its purported effects on blood circulation, hemostasis (stopping bleeding), and reducing swelling. Its use to support the "Solar Plexus" body system is largely rooted in the traditional energetic frameworks of Chinese medicine, where the solar plexus area is associated with the digestive system, metabolism, and energy distribution. Traditional Chinese Medicine (TCM) practitioners sometimes use Panax pseudoginseng to "invigorate the blood" and support gastrointestinal function, which may be conceptually linked to the solar plexus or "middle burner" (Zhong Jiao) in TCM theory.

However, while Panax pseudoginseng has a well-established traditional use for blood-related and circulatory issues, there is limited scientific research directly supporting its effects on the digestive system or metabolic functions specifically associated with the solar plexus. Most scientific studies focus on its saponin content (notably notoginsenosides) and effects on bleeding disorders, cardiovascular health, and inflammation. There is a paucity of clinical trials or mechanistic studies validating its use for the solar plexus or related digestive/metabolic health in biomedical terms.

In summary, the association between Panax pseudoginseng and the solar plexus is primarily traditional, based on TCM concepts, with little scientific validation for this specific use.
