===Kalpana Chatushka (four chapters on therapeutic purification procedures)===  

The next tetrad, ''Kalpanachatushka'', deals with the application of medicines in the form of various therapeutic purification procedures either in healthy or in diseased individuals. ''Shodhana'' (bio-purification procedures) is an important concept of [[Ayurveda]] prescribed for removal of toxic wastes from the body. To prepare the patient for bio-purification, he has to go through specific pre-shodhana procedures, such as ''[[snehana]]''(internal application of ''sneha'' (fat)) and ''[[swedana]]''(sweating), to mobilize toxic wastes within the body and excrete them out of the body.

* The first chapter, [[Snehadhyaya]], provides the guidelines for proper use of ''sneha''(lipids) either for ''shodhana'' or for ''shamana'' (to appease/palliation) purposes. A patient who has successfully completed the ''[[snehana]]'' procedure is now subjected to ''[[swedana]]'' procedure.

* The next chapter, [[Swedadhyaya]], explains the various types of ''[[swedana]]''(fomentation) recommended for various diseases. ''[[Snehana]]'' and ''[[swedana]]'' help the toxins to move towards the gut from where they will be expelled out of the body either through ''[[vamana]]''(therapeutic emesis) or ''[[virechana]]''(therapeutic purgation).
