Clerodendrum phlomidis has a history of traditional use in various systems of medicine, particularly Ayurveda, for gastrointestinal ailments including ulcers. More recently, scientific studies have evaluated its potential anti-ulcer properties. The most notable evidence comes from preclinical (animal) studies. For instance, research published in the journal Phytomedicine (2003) reported that extracts of Clerodendrum phlomidis leaves showed significant protective effects against experimentally induced gastric ulcers in rats. The effects were attributed to its antioxidant activity, increased mucus secretion, and possible inhibition of gastric acid secretion. Additionally, studies have suggested that the plant's flavonoids, terpenoids, and phenolic compounds may contribute to these gastroprotective effects.

However, it is important to note that the evidence is limited to animal models, and there is a lack of robust clinical trials in humans. Therefore, while there is scientific validation at the preclinical level, the evidence is not strong (rated 2/5) and cannot be considered conclusive for humans. Further research, particularly clinical studies, is needed to fully establish the efficacy and safety of Clerodendrum phlomidis for the treatment or support of ulcers in human populations.
