Peptic ulcers, or open sores in the stomach or duodenum, can cause a great deal of discomfort. What's more, it affects a disproportionately significant percentage of people worldwide. Preliminary phytochemical study revealed that the Ethanol flower extract of Rhododendron arboretum (ELRA) is rich in Alkaloids, saponins, tannins, flavonoids, reducing sugars, and glycosides, all of which have been linked to poor dietary habits, prolonged use of nonsteroidal anti-inflammatory drugs (NSAIDs), stress, and infection. ELRA's significant antiulcer and wound healing actions may be due to the presence of flavonoids and saponins, as suggested by preliminary phytochemical data. This study lends credence to the long-held belief that Rhododendron arboreum flower is an excellent herbal therapy for the treatment of peptic ulcers. More conclusive research on the therapeutic efficacies of Rhododendron arboretum flower is needed, specifically regarding the plant's efficacy, protection, and in vivo toxicity. This research suggests that Rhododendron arboreum ethanol floral extract (ELRA) may be useful for the treatment of peptic ulcers.
