With respect to the action of Basti in general, it is important to know the procedure and the pathway that it covers. Basically Basti or enema is given through the anal route and is pushed into the large intestine with a controlled uniform force. The medicine thus moves from the anus to the large intestine upto the ileocaecal junction. The content of the medication being oil in medium, this will be giving the much needed lubrication to the walls of the intestine. For enhancement of the benefit, these oils are processed with different medicinal herbs such that it also gives a local healing effect too. 

Not only this, it is also accepted that there is considerable absorption of water, salt, protein, carbohydrates and fat from the large intestine which makes the media all the more useful for giving adequate nourishment along with local repairing of the intestines. The absorption is more when the pH of the contents is basic while it is less when it is acidic. Large intestines are a preferred site for the absorption of proteins as the hydrolysis of these is prevented giving a better chance of providing nutrition to the body. But the absorption is largely dependent on the medicaments that is being used in the process where the role of Anuvasanopaga substances is seen. Now these absorbed nutrients and potential properties of the medicinal substances that are processed in the oil, will reach the heart through the portal and iliac veins that drain to Inferior Venacava as these two are the main vessels that are involved in the venous drainage of the large intestine, anus and rectum. Thus the nutrients and properties of medicaments reach all parts of the body. Moreover, ENS (Enteric Nervous System) which is referred as the second Brain of the body is also stimulated by the potentiated properties and nutrients that get absorbed during the procedure. The total minimum duration of retention is 9 hours but may extend further which makes it all the more useful in facilitating absorption and providing the benefits of the treatment.

Here the substances or circumstances that are classified as anuvasanopaga will either enhance the level of nutrients as in case of foods, potential properties as in case of medicine or the reduction of the time duration to accomplish the benefits by different advised lifestyle. Thus, leading to the increased benefits of the procedure for which it is undertaken. Basically, the procedure is the one that promotes strength and increase the vitality but when the oil which is used is processed with the medicaments then it also has the potency to provide extra benefits accordingly.
