Rugose Rose (Rosa rugosa), also known as Japanese rose, has a history of use in traditional East Asian medicine for various ailments, including respiratory issues. In traditional Chinese medicine (TCM), the petals and hips of Rosa rugosa are sometimes incorporated into herbal formulas believed to "clear heat" and "moisten the lungs," which are terms used to describe the treatment of coughs or asthma-like symptoms. However, the specific use of Rugose Rose for asthma is not a prominent or well-documented application in either the classical texts or modern ethnobotanical literature. Most references to its medicinal use focus on digestive, gynecological, or skin-related conditions.

Scientifically, there is little to no direct evidence supporting the efficacy of Rugose Rose in treating asthma. Some laboratory studies have explored the general antioxidant and anti-inflammatory properties of Rosa rugosa extracts, but these do not specifically address respiratory conditions like asthma. No clinical trials or robust animal studies currently validate its use for asthma management. Thus, while there is a minimal traditional precedent, the evidence base supporting its use in asthma is very weak.
