[Frequency of anuvasana basti] Persons who are habituated to take dry food, having strong digestive capacity, those indulged in physical exertion, sufferers of vata disorders, whose pelvic and hip regions are afflicted with vata and who are suffering from udavarta should be given anuvasana every day.
As the water falling on sand gets absorbed immediately, similarly the fat given to these patients gets immediately digested. In case of others the agni generally digests sneha in three days.

[Instructions before basti administration] Advice regarding basti administration: • Plain/ unprocessed fat should not be used for anuvasana basti as it produces abhishyanda (stuffiness) in the rectum.

• Some portion of fat should be allowed to remain in basti because in attempt to give complete basti, some portion of vata also goes inside. • Use of fats orally and through basti simultaneously should be avoided as it vitiates vata and agni.

[Importance of alternate administration of sneha and niruha basti] Either niruha or anuvasana should not be given continuously in excess as, continuous anuvasana causes utklesha (excitement of dosha) and suppression of digestive power. Continuous excess niruha causes vata aggravation.
