The use of Indian Coraltree (Erythrina variegata) in the management of emphysema is primarily rooted in traditional medicine rather than scientific validation. In Ayurveda and some other traditional healing systems, Indian Coraltree has been used to address various respiratory issues, including coughs, asthma, and bronchitis. The rationale for its use generally stems from its reputed anti-inflammatory, antispasmodic, and expectorant properties. However, specific references to its use for emphysema—a chronic obstructive pulmonary disease characterized by damage to the alveoli—are sparse and typically anecdotal.

Scientifically, there is very limited evidence regarding the efficacy of Erythrina variegata for emphysema. Laboratory studies have identified some anti-inflammatory and antioxidant activities in extracts of this plant, but these findings have not been directly linked to the treatment or improvement of emphysema in clinical or preclinical models. No controlled human studies or robust animal studies specifically investigating its effects on emphysema exist in the peer-reviewed literature as of 2024. Therefore, while the traditional use of Indian Coraltree for general respiratory complaints is documented, its specific application for emphysema lacks scientific substantiation and rests on historical precedent rather than empirical evidence.
