Study of Kāla as a causative factor and Asātmyaja Roga in Ŗtusandhi

Description of the etiological factors as 'Trividha-Het' is unique classification in yurveda. Amongst these three factors Kla (time-factor) is beyond the reach of human. It is unavoidable. It is the root cause of climatic changes which we called as seasons i.e. 'TU'. Such climatic changes are responsible for development of various signs & symptoms which are known as 'symptoms due to season change'. To avoid these seasonal illness & maintain health throughout the year, seasonal regimen i.e. tucary is described in yurveda. Some signs and symptoms or diseases are likely to occur during the joining period of two consecutive tus, specified for two weeks and termed as tusandhi. If one disobeys these rules, particularly in tusandhi then he mostly suffers from the typical signs and symptoms termed as Astmyaja Roga in tusandhi. Study & practice of tucary helps to prevent the onset of signs and symptoms i.e. 'Astmyaja Roga' in tusandhi. This book is based on the fundamental concepts of yurveda with survey study of 100 individuals particularly in 3 tusandhis. The detailed tucary is also illustrated in this book.
