Clinically, there is no such thing as “internal fever”, but there is internal heat. Clinically, internal heat can be divided into real and virtual. Patients with real heat may have symptoms such as high fever, red face, thirst and coldness; patients with virtual heat may have symptoms such as hot flashes (a burst of fever), night sweating (abnormal sweating after going to sleep, but sweating stops after waking up), and emaciation. It can be treated with medications such as Longdian Diarrhea Liver Pill and Tianwang Tonicheart Dan. Longdian Diarrhea Liver Pill is used for dizziness and red eyes (dizziness and red eyes) caused by damp-heat of liver and gallbladder (damp-heat evils accumulating in the liver and gallbladder), tinnitus and deafness, dystocia and bitterness of mouth (feeling pain in the area of the dystocia and ribs and bitterness of the mouth), redness of urine, and damp-heat with menorrhagia. It should not be taken for a long time by those with weak spleen and stomach, and should be used with caution by pregnant women and those with stomach cold.
