Patrinia, known as "Bai Jiang Cao" in traditional Chinese medicine (TCM), has been used historically to manage inflammatory and infectious conditions of the gastrointestinal tract, including enteritis. Its use for enteritis is primarily justified by tradition rather than robust modern scientific validation. Traditional texts describe Patrinia as having "heat-clearing" and "detoxifying" properties, making it a common ingredient in herbal formulas intended to alleviate symptoms like abdominal pain, diarrhea, and inflammation associated with enteritis and related disorders.

In terms of scientific evidence, a limited number of preclinical (animal and in vitro) studies suggest that extracts of Patrinia species may possess anti-inflammatory and antibacterial properties, which could theoretically be beneficial in treating enteritis. For example, some studies have demonstrated inhibition of pro-inflammatory cytokines and suppression of inflammatory pathways in animal models. However, well-designed clinical trials in humans are lacking, and there is insufficient evidence to firmly establish its efficacy or safety for enteritis from a modern medical perspective.

In summary, while Patrinia is used in TCM practice for enteritis based on traditional principles and some preliminary biological plausibility, the overall supporting evidence is weak and mainly historical. It is important for patients to consult healthcare professionals before using Patrinia for enteritis, especially given the lack of strong clinical data.
