Professor Cui Gong-rang believes that the etiology of gouty arthritis can be summarized as damp-heat stagnation, blood stasis and insufficient spleen and kidney. The root of gouty arthritis is deficiency of kidney-yang. Deficiency of spleen-yang caused by deficiency of kidney-yang leads to poor transportation and transformation of grain essence, flowing into the four ends of limbs and transforming into heat, and showing red, swollen, hot and painful symptoms. The key to the differentiation of symptoms and signs is to distinguish deficiency from excess, and secondary from primary, so it is very important to grasp the swelling and pain of joints and the insufficiency of spleen and kidney, which is called "considering two", and the relationship between the two is"middle". Professor Cui has divided the disease into damp-heat stagnation syndrome, blood stasis syndrome, spleen and kidney insufficiency syndrome. Guided by the thought of"considering two and using middle", he often uses Self-made Qubi Tongfeng Yin (QBTFY) and has achieved good therapeutic effect on gouty arthritis.
