A multi-faceted pharmacology of Pistacia Integerrima mitigating asthma: a review on ethnopharmacology, phytochemicals, mechanisms, and formulations
摘要
Asthma is a chronic inflammatory disorder of the airways, characterized by hyperresponsiveness, airflow obstruction, and recurrent respiratory symptoms. Despite advancements in pharmacological treatments, current therapies often have side effects and show variable effectiveness, underscoring the need for safer and more effective alternatives. Pistacia integerrima J.L. Stewart ex Brandis, commonly known as Kakarsinghi, has traditionally been used in South Asia to treat respiratory conditions, including cough, bronchitis, and asthma. This practice is prevalent in Ayurveda, Unani medicine, and local folklore. Phytochemical studies have identified various bioactive compounds in Kakarsinghi, including flavonoids, terpenoids, and phenolic acids, which exhibit antioxidant, anti-inflammatory, immunomodulatory, and bronchodilatory properties. Preclinical research demonstrates that P. integerrima extracts and isolated constituents can modulate key molecular pathways associated with asthma pathophysiology, including the inhibition of NF-κB, suppression of inducible nitric oxide synthase, modulation of mast cell stabilization, and downregulation of Th2 cytokines such as IL-4, IL-5, and IL-13. Clinical studies indicate that galls may effectively prevent respiratory attacks and enhance chest expansion and respiratory rate when used in poly-herbal formulations. These findings support the traditional use of galls and suggest their potential as an adjunct therapy. This review speculates on the available data, comprising ethnobotany, phytochemistry, pharmacology, and multifaceted therapeutic prospects of P. integerrima, highlighting its potential role as a natural intervention for asthma.
