Samprapti

The complete route of the disease’s manifestation.

Samprapti – Development of the disease
Samyak means “proper” and prapti is “to get.” Samprapti is to get the proper knowledge about the pathway of disease manifestation. This provides complete knowledge of the disease progression, starting from the cause, the doshas involved and the location where aggravated doshas are accumulated (dooshya). All the bodily changes that occur from the time of exposure to the causative factor, to the actual onset of disease and its manifestation are placed under this category.
