QUOTE : Raw humor is a quality issue that has to be dealt with; the quality of the humor, or a metabolite in our modern biology, is an important factor in health preservation, a fact that is rarely given attention when merely measuring the quantity of a biomolecule. In a Western-type clinical environment, the physician or nurse may not be aware of this issue since all blood indicators they deal with are quantitative and only measured in the blood, the assessment and treatment is based on whether the test results show above or below the normal range. According to Avicenna, in many instances the raw humor may be higher in concentration within the organ, and not within the vessels, and its effect is local rather than systemic.
