Small Intestine (Xiao Chang)


Functions of the Small Intestine

The Small Intestine receives grains and water that have been decomposted by Stomach and Spleen, and divides pure from impure. The Small Intestine transforms the food further and absorbs nutrients for the body. The clear aspects are passed on to the Spleen and sent to the Lungs. The impure and turbid parts are passed on by the Small Intestine. Waste is passed on to the Large Intestine and waste fluids are passed on to the Bladder. The Small Intestine relies on the Kidney Yang to fulfill its function.

The Heart stands in interior-exterior relationship with the Small Intestine. The relationship between Heart and Small Intestine can also be transferred to the mental level. The Heart houses the spirit. The Small Intestine divides pure from impure and helps the spirit in its discernment of important and unimportant. The Small Intestine Qi aids clear thinking. "Small-Intestine-days" are days on which we clean out our house and let go of unnecessary objects.
Small Intestine disorders are usually caused by Spleen Yang Deficiency, Kidney Yang Deficiency, or by Heart Fire that spreads to the Small Intestine.
