Conceptual Study of Aushadha Sevan Kala (Time of Drug Administration) in Samhitas, Commentaries and Its Modern Correlation: A Review

Ayurveda treats illnesses using a systemic method. One of its features is Bhaishajya-kaal, or the ideal moment to provide a medication. It is well known in Ayurveda that a medication given either before or after time is useless. When a medication is given at the wrong moment, its full benefits never manifest. Ayurveda is a medical science that focuses on the underlying cause of disease rather than the symptoms. Ayurveda has a unique approach to disease treatment. Fundamental Ayurvedic concepts indicate to the eradication of the underlying cause of disease during treatment. However, not all Ayurvedic therapy concepts, including Bhaishajya Kaal, are being followed nowadays. Today, the Ayurveda fraternity is losing the practical application of its fundamental ideas. As a result, the Ayurveda fraternity does not receive shashtrokta phala of medicine. This article will provide insight into the notion of Bhaishajya Kaal. The introduction of Bhaishajya Kaal will provide guidance on which medications should be provided to maximize advantages. According to the pathology of sickness, Acharyas had suggested Bhaishajya-Kaal. Dosha vitiated and Sthan in a given illness are the primary factors that determine when to administer medication. The ancient Acaryas examine the relationship between Bheshaj and Kaal in a number of ways. Bhaisajya-Kaal is a prime example of how the Kaal concept can be applied to the treatment of illnesses. While kaal is a distinct and distinctive cause of all kinds of outcomes, it is also inevitable. It is known as Anavathasiddha Nimitta Karana, which indicates that without Kaal's causal link, no action is feasible. This is why the idea of Kaal is emphasized in Ayurveda, which is a study of life. According to Acarya Vagbhata, Kalo Bhaisajya Yoga Krit (A. S. Su. 1/45)1, or Kaal, achieves the goal of Bheshaj management. The timing of medicine delivery is crucial because some medications must reach a steady level in the bloodstream to be effective. Certain medications must be delivered within a specific time frame, such as before, after, or with a meal. For example, rapid, short, and ultra-short acting insulin is typically administered before a meal. Because modern medicine is focused on medication pharmacokinetics, the timing of administration is determined by the drug rather than the patient. In Ayurveda, the timing of drug administration is determined by the type of the condition, the vitiated Dosha, the patient's Prakruti, and the drug's action.
