Ajirna: An Ayurvedic perspective on Indigestion

Abstract

Ayurveda emphasizes the central role of Agni (digestive fire) in maintaining overall health and well-being. Ajirna (indigestion) is a pathological state arising due to the impairment of Agni, leading to the formation of Ama (undigested metabolic toxins), which serves as a precursor to various systemic diseases. The primary etiological factors of Ajirna include improper dietary habits (Ahara), an unhealthy lifestyle (Vihara), and psychological disturbances (Manasika Bhava). Classical Ayurvedic texts, including the Charaka Samhita, Sushruta Samhita, and Ashtanga Hridaya, classify Ajirna into different types based on Dosha predominance, namely Amajirna (Kapha-dominant), Vidagdhajirna (Pitta-dominant), and Vishtabdhajirna (Vata-dominant), along with other forms such as Rasasheshajirna, Dinapaki Ajirna, and Vilambika Ajirna. The dysfunction of Agni results in three pathological states: Mandagni (weakened digestion), Tikshnagni (hyperactive digestion), and Vishamagni (irregular digestion), all of which contribute to digestive disorders. The management of Ajirna in Ayurveda focuses on restoring Agni, eliminating Ama, and correcting underlying lifestyle and dietary imbalances. Therapeutic approaches include Langhana (fasting), Deepana (appetite-stimulating), Pachana (digestive aids), and Vatanulomana (regulation of Vata movement), along with Panchakarma therapies and Pathya-Apathya (dietary and lifestyle modifications). This paper aims to comprehensively explore Ajirna from an Ayurvedic perspective by integrating classical textual references with evidence-based therapeutic interventions for sustainable digestive health.
