The purpose of this study is to determine the effect of Zataria multiflora Boiss and Sumac on the thermic effect of food, activity of sympathetic - parasympathetic system: comparison between warm and cold temperament people.

Human body needs to energy in order to preserve life.There are three forms of energy consumption at body, consumption at baseline or resting, consumption at energy expenditure for Thermic effect of food and energy is spent in physical activity.Also from the perspective of traditional medicine, cold and warm natured people are determined based on certain mental and physical protests.

There are different temperament not only in Traditional Iranian Medicine, but in traditional Chinese medicine, Indian, Greek, Arabic, Romanian, and there are European.As various factors on the basal metabolism and thermic effect of food , also are several factors such as age, sex, physical condition of the environment that have an impact on individual temperament.

Since the protests seem warm and cool temperament and factors affecting on their basal metabolic rate and thermogenesis so that food may explain the relationship between warm and cold temperament to mind is the basal metabolism; It seems those are hot temperament, their basal metabolic rate is higher BMR than normal and those who are cold temperament, have a lower BMR.

On the other hand seems that thermic effect of food in people who have hot temperament is higher than thermic effect of food in people who have cold temperament.

So that we need to use of two nutrient foods, in this way we consided the multiple criteria and then were selected sumac and thyme.

On the other hand, in order to study possible mechanisms affecting basal metabolism, thermogenesis of food, according to previous studies and also matches that there are between sympathetic - parasympathetic and thyroid function, with symptoms of cold and warm temperament there, checking of activity of these organs seems necessary.

Because to maintain basal metabolic rate is essential for human life, so that each factor in order to better understand these is helpful to human life.And the need for such study makes clear;Through this step help toward improving public health
