Sanskrit Verse
नियतं मरणं यस्मात् तस्मादरिष्टमुच्यते।
— (Charaka Samhita, Indriyasthana 1/4)
Explanation
Arishta signs are fatal or prognostic signs that indicate the incurability of a disease and the impending death of the patient. These are specific signs and symptoms related to the patient’s physical appearance, behavior, and sensory perception that signify a complete collapse of the body’s life-sustaining mechanisms.
Clinical Importance
The knowledge of Arishta signs is crucial for a physician to determine the prognosis of a disease. It helps in deciding whether to continue treatment or to focus on palliative care, and to inform the patient’s family about the severity of the condition.
