This paper summarizes Professor AI Rudi's clinical experience in applying the promoting blood circulation method for staged treatment of diabetic foot. He considers the core pathogenesis of diabetic foot to be deficiency of vital

qi

with invasion of pathogenic factors， and obstruction of the vessels by dampness and blood stasis. Among these， insufficiency of the spleen and stomach and malnourishment of the vessels are the root causes， while retention of turbid dampness and blood stasis in the vessels represents the secondary manifestation. Diagnosis and treatment emphasize pulse examination of the lower limbs； specifically， assessing the

Fuyang pulse

（趺阳脉），

Taixi pulse

（太溪脉）， and

Weizhong pulse

（委中脉） to determine disease severity. In the pre-ulcerative stage of diabetic foot， the treatment focuses on dispelling dampness and resolving stasis. For patients with cold-damp obstructing the vessels， the principle is to warm and transform cold-damp， disperse accumulation， and restore vessel patency； the internal treatment uses a self-formulated prescription

Tuoju No.1 Formulation

（脱

疽1号方）， while the external treatment includes fumigation with the self-prepared

Wenyang Tongluo Formulation

（温阳通络方） and topical application of the self-prepared

Woxue Ointment

（沃雪膏）. For patients with damp-heat and stasis obstructing the vessels， the principle is to drain dampness， clear heat， transform stasis， and unblock the vessels； internally administered

Tuoju No.2 Formulation

（脱疽2号方）， with external fumigation using the self-prepared

Jiedu Xiaozhong Powder

（解毒消肿散） and topical application of the self-prepared

Wumiao Ointment

（五妙膏）. In the ulcerative stage， the principle is to combine unblocking and supplementation， nourishing and activating the blood， tonifying

qi

， and protecting the vessels. Internally，

Tuoju No.3 Formulation

（脱疽3号方） is prescribed； externally， the self-prepared

Rumo Xuejie Powder

（乳没血竭散） is applied topically， together with

Shengji Yuhong Ointment

（生肌玉红膏） for wound healing.
