In the world of Ayurveda, the concept of “Abhava Pratinidhi Dravya” takes center stage as a pragmatic solution to herbal unavailability. This concept hinges on the practice of substituting one herb with another, provided they share similar properties and actions. Such substitutions may arise due to a range of factors, including the unavailability of the original herb, cost considerations, or practical constraints. The herb chosen for substitution is aptly termed the “substituent.”
