background : the authors of this manuscript aimed to show the importance of porosity and condensation in health according to traditional persian medicine ( tpm ) with consideration of new evidence in conventional medicine.methods:cardinal traditional medical and pharmacological texts were searched for the traditional terms of takhalkhol ( porosity ) and takassof ( condensity ) focused on preventive methods . 
 the findings were classified and compared with new medical findings.results:according to traditional persian medicine , porosity and condensity are the two crucial items that contribute to human health . 
 somatotype is a taxonomy based on embryonic development , which may be considered in parallel with porosity and condensation . 
 however , these terms are not completely the same . 
 there are many causes for acquired porosity comprising hot weather , too much intercourse , rage , starvation , and heavy exercises . in general 
 , porosity increases the risk of diseases as it makes the body organs vulnerable to external hot and cold weather . on the other hand , 
 the porose organs are more susceptible to accumulation of morbid matters because the cellular wastes can not be evacuated in the normal way . 
 there are some common points between traditional and conventional medicine in the context of porosity and condensity . 
 the relation between diet and somatotype is an example.conclusion:condensity and porosity are the two basic items cited in the tpm resources and contribute to health maintenance and disease prevention of body organs . creating a balance between these two states in different body organs , 
 strongly contributes to disease prevention , treatment and diminishing chronic diseases period . 
 choosing proper modality including diet , drug therapy , and manual therapy depends on the amount porosity and stiffness of the considered organ and the preferred porosity of the affected organ keeping in a normal healthy state .
