Body detox cleansing is called for when there is enervation or fatigue in the body.
Fatigue makes it hard for the stomach to create the acids needed to activate digestive enzymes secreted when chewing. Meaning the enzymes are slowing in digesting carbohydrates, fats and proteins.
Undigested food then becomes the base for feeding a variety of microbes that may be in your stomach due again in part to low digestive acid.
Food then putrefies until the acid level is high enough to activate the pylorus valve so the chyme can pass into the small intestines for further digestion.
A chronically low digestive system can be helped by resting the system with simple nutritious foods, adding digestive enzymes and hydrochloric acid as well as anti-putrefactive herbs. A low functioning digestive tract allows a build up of toxic organisms which can blossom when highly refined and processed foods are consumed.
If memory serves, clove, cinnamon and myrrh were key anti-putrefactive herbs used to preserve mummies for thousands of years. These same herbs and others are used in chutney to preserve fruits and vegetables, prevent spoilage and food borne illnesses that result from spoiled food.
These sorts of herbs can be used to assist digestion when the stomach is weak and not able to provide needed enzymes for digestion.
These same herbs and others reduce putrefaction in your stomach, small intestines and colon.
Natural plants, vegetables, and fruits are high in anti-putrefactive nutrients. By natural I mean plants grown in soil with a proper balance of soil nutrients. My experience with tomatoes for example grown in balance soil makes for a fruit that does not spoil but dries out for long-term storage as compared to a store purchased product that spoils and rots very easily. I believe its the nutrients in the natural product that give it storage ability and which when eaten give your body resistance to microbes that create toxicity. Tomato is only one example.
When you make the contents of your gut benign, you reduce the toxic load on the liver. When you make the contents of your gut benign, the colon produces less toxic waste which is absorbed into the blood for processing by the liver.
You further support detoxification by cleansing the liver and recharging the bodies content of nutrients needed by the liver for detoxifying harmful substances. Improving bowel transmit time with colon cleansers also support the detoxification process including environmental chemical removal.
