发背寒热，是由于寒气侵入经络，导致气血运行受阻。血液凝涩不畅，从而结成疮肿。同时，诸阳之气聚集于此，寒邪转化为热邪。热势炽盛则肌肉腐败化为脓液。这都是因为脏腑气机壅滞，毒邪无法宣通散发，所以出现寒热症状。

Haibei (Back Carbuncle) with alternating chills and fever is caused by cold pathogen invading the meridians, obstructing the flow of Qi and Blood. The blood becomes stagnant and fails to circulate smoothly, resulting in the formation of sores and swellings. Furthermore, Yang Qi gathers at this site, transforming the cold pathogen into heat. When heat becomes excessive, flesh rots and turns into pus. These conditions are all due to stagnation and obstruction within the Zang-Fu organs, preventing the dispersion and unblocking of toxic factors, thus causing alternating chills and fever.
For treating Haibei and all types of carbuncle toxins that cause attacking alternating chills and fever, along with constipation and dryness of the large intestine, it is appropriate to take Loulu San (Blue Vetch Powder) for removing irritability and heat, detoxifying, and resolving toxicity.
