Many of the preparations and individual ingredients of Ayurveda aid in digestion and keeping the body in balance, and most of the diet principles complement the tonics or specific recommendations of practitioners. When a person is suffering from poor health or even poor happiness, Ayurvedic medicine also encourages a good cleansing of the insides for improved overall health.
Panchakama is the name of the process for getting rid of food and impurities that interfere with how the body should ideally work. Administering enemas, oils and massage therapy all help get the body moving from the tissue level to the intestinal level as impurities get released from the system. Breathing, digestion and thinking are thought to improve, and having a cleansed inside also allows for more filling spiritually.
Achieving balance through cleansing should be done carefully and with the go-ahead of your physician or a reputable Ayurvedic practitioner. Overdoing it can lead to deficiencies of vitamins and minerals as well as some of the body's healthy bacteria, which are also needed for digestion and balance.
