Body fever is yin deficiency or yang deficiency

Body fever is usually due to yin deficiency.

Yang deficiency is usually caused by yang deficiency, resulting in excessive yin qi, decreased function and reduced heat production. Clinically, it is mainly due to cold syndrome, such as pale complexion, fear of cold and cold limbs, cold limbs, fatigue and weakness. Yin deficiency is usually caused by fever and miscellaneous diseases for a long time, resulting in yin fluid depletion and relatively vigorous yang heat qi. Clinically, it is mainly caused by heat syndrome, such as dry mouth, hot flashes and night sweats, five-upset fever, hand and foot heart fever, flushing of face, red tongue and less fluid, short red urine, thin pulse and facial fever, etc., so body fever is usually yin deficiency.
