A Critical Review on Aushadh Sevan Kala

Abstract

The kind of Avasthika Kala intended for the appropriate timing of medication administration is called Aushadh Sevan Kala. When treating a patient, Trisutra Ayurved is crucial. Hetu (causative factors), Linga (signs and symptoms) and Aushadh (medicine) are considered as Trisutra Ayurved. According to Acharya Charaka medicines having opposite properties of Desha (habitat), Matra (dose) and Kala (time) are able to cure the diseases easily. Additional aspects that should be considered when treating a patient are Desha (region), Kala (time), Pramana (dosage), Satmya (wholesomeness), Asatmya (unwholesomeness), Aahara (food), and Aushadh (medication), according to Acharya Charaka. According to Acharya Charaka medicines with opposite properties than Dosha, Dushya and Nidan (causative factor) gives better result when used as a treatment. Since Agni is the most important component for sustaining Dhatu Samya, all therapies aim to preserve Agni\'s power. Aushadh Sevan Kala will assist with diet and medication interactions, which will enable the patient receive prompt and long-lasting comfort. One crucial element that needs to be taken into account throughout treatment is kala, or time.

Introduction

This text discusses the Ayurvedic concept of Kala (time) and its importance in the administration of medicines. In Ayurveda, Kala is considered a significant factor influencing the effectiveness of treatment. It is classified into two broad categories: Niyat (continuous or fixed time) and Aniyat/Awasthik Kala (situational or condition-based time). Among the various applications of Kala, Aushadha Sevan Kala (the proper timing of medicine administration) is particularly important because medicines administered at the correct time are believed to produce better therapeutic outcomes.

Ayurveda recognizes two major aspects related to therapeutic timing: Shad Aveksha Kala and Bhaishajya Kala. Shad Aveksha Kala consists of six factors that should be considered before treatment: day (Dina), patient (Rogi), medicine (Aushadha), disease (Vyadhi), digestive status (Lakshana Jeerna), and season (Ritu). Bhaishajya Kala refers specifically to the timing of medicine administration and is known by several synonyms such as Aushadha Kala and Bhaishajya Grahana Kala.

Different Ayurvedic texts describe varying numbers of medicine administration times. While Acharyas Charaka, Sushruta, and Ashtanga Sangraha describe ten Aushadha Kalas, Ashtanga Hridaya mentions eleven and Sharangadhara Samhita describes five major timings. These timings are selected according to the patient's condition, disease type, digestive strength, and dosha imbalance.

The principal Aushadha Kalas include:

• Niranna (Abhakta) – medicine taken on an empty stomach, indicated for strong individuals, Kapha-Pitta disorders, and conditions requiring strong digestive activity.
• Pragbhakta – medicine administered before meals, useful for disorders of Apana Vayu and diseases affecting the lower part of the body.
• Madhyabhakta – medicine taken during meals, especially beneficial for Samana Vayu disorders, digestive disturbances, and Pitta-related diseases.
• Pashchatbhakta – medicine administered after meals, indicated for Vyana Vayu disorders and diseases affecting the upper body.
• Sayampashchat – medicine given after the evening meal, mainly for Udana Vayu disorders.
• Antarabhakta – medicine administered between two meals, beneficial for digestive disorders, heart health, and Vata-related conditions.
• Sabhakta – medicine mixed with food, particularly suitable for children, elderly individuals, weak patients, and those who dislike medicines.
• Grasa-Grasantara – medicine taken between mouthfuls of food, often recommended for Prana Vayu disorders and powdered formulations.
• Samudga – medicine administered both before and after meals, used for disorders such as hiccups, tremors, convulsions, and spreading dosha conditions.
• Muhurmuhu – repeated administration at short intervals, indicated for acute conditions such as cough, breathlessness, thirst, vomiting, poisoning, and voice disorders.
• Nishi – medicine administered at night, particularly for diseases affecting areas above the neck.

The discussion section explains the rationale behind each timing. Ayurveda emphasizes that the interaction between medicine, food, digestive fire (Agni), and bodily doshas determines therapeutic effectiveness. For example, medicines taken on an empty stomach directly interact with digestive fire, whereas medicines mixed with food are distributed throughout the body with digested nutrients. Similarly, medicines given before, during, or after meals target different physiological processes and dosha functions.

Conclusion

Ayurvedic medicine is far more concerned with the timing of medicinal administration. Clinically, the significance of Aushadha Sevana Kaal is more cardinal, as without it all the medicine and food will be for naught. The Bhaishajya Kaal explained by Acharyas seems to be based on the routine we follow in a day from morning to night along with the predominance of Dosha. Oral administration is the cornerstone of all Kaal. However, it should not be used in an emergency. Medicines should be taken with fluctuations as per the biological clock of the body. Meanwhile, it looks like the timing of drug administration in disease therapy has a major impact on treatment success. But in Ayurveda, Bhaishajya Sevan Kaal is a more concerned subject while treating disease. Bhaishajya Sevan Kaal can also be helpful in the development of new methods for treating both traditional and modern lifestyle illnesses. In this study, in comparison with both sciences; we got both similarities and dissimilarities too in Aushadha Prayoga Kaal. Both sciences are standing on their principle, but the aim is to increase the treatment efficacy and to minimize drug toxicity. So, it is more important that we should take account of Aushadha Prayoga Kaal while drug administration. As a result, a Vaidya with a thorough understanding of Bhaishajya Sevan Kaal can treat patients more effectively and achieve better disease outcomes.
