Fragrant Angelica (Angelica dahurica), commonly referred to as Bai Zhi in Traditional Chinese Medicine (TCM), has been used historically to support the Stomach body system. In TCM, Bai Zhi is classified as an herb that "expels wind" and "alleviates pain," but it is also used for its purported effects on the digestive system, particularly to address issues such as stomachache, abdominal fullness, and poor appetite. The traditional rationale is based on its warming properties and its supposed ability to disperse cold and dampness, which are considered causes of digestive discomfort in TCM theory.

Scientific evidence supporting these uses is limited. Most studies on Angelica species focus on their anti-inflammatory, analgesic, or antimicrobial properties, rather than direct effects on the stomach or digestive processes. While some animal research suggests potential benefits for gastrointestinal motility or as an anti-ulcer agent, these findings are preliminary and not specific to Fragrant Angelica (Angelica dahurica). Furthermore, robust clinical trials in humans to verify its efficacy for stomach-related conditions are lacking.

In summary, the use of Fragrant Angelica to support the Stomach is primarily justified by traditional practices, with limited scientific validation at this time.
