Ayurvedic Principles

Koshta in Ayurveda

KOSHTA is a unique concept in ayurveda. It is defined as nature of digestive tract, which represents motility of the intestines and movement of food and fecal matter in the alimentary canal and elimination of the stool.


According to Ayurveda, KOSHTA has three main categories according to the dominance of the Dosha in the body or ayurvedic body type.

KOSHTA Type Dominant Dosha
KRURA (Hard) Vata Dosha
MRIDU (Soft) Pitta Dosha
MADHYA (Moderate) Kapha Dosha


KRURA KOSHTA means Vata is more dominant in the alimentary canal, which reduces liquid content in the stool and resulting in elimination of hard stools. It causes difficulty in elimination and may also dry the stool.

LAGHU (Light) and RUKSHA (Dry) qualities of Vata reduces softness, stickiness, and oiliness of the stool. However, these qualities are also required in harmony with others for proper elimination of the fecal matter and preventing the loose stools, but in KRURA KOSHTA, these qualities are more than the usual, which may result in:

  • Difficulty in defecation
  • Hard and dry Stool
  • Constipation commonly occurs

It is not necessary that KRURA KOSHTA causes these symptoms or problems, but people with it are more prone to these problems.


MRIDU KOSHTA means Pitta is predominant in the alimentary canal, which slightly increases the liquid content due to its DRAVA (liquid) quality in the fecal matter resulting in semi-solid discharge of fecal matter.

People with MRIDU KOSHTA are more prone to following health conditions:

  • Loose stools or semi-solid stools
  • Increased frequency of defecation
  • Diarrhea can commonly occur

It is not necessary that MRIDU KOSHTA causes these symptoms or problems, but people with MRIDU KOSHTA are more prone to these problems.


MADHYA KOSHTA means Kapha is more predominant in the alimentary canal resulting in passage soft and solid stool, which is desirable and ideal. The optimum level of Kapha keeps the VATA and PITTA under control and prevents loose and hard stools.

When Kapha is excess in the alimentary canal, mucus content is observed in the stool. It is more common problem in people with MADHYA KOSHTA.
