Conditions
Dioscorea hemsleyi is one of the seven traditional medicinal plants included in the BuZangTongLuo decoction used to combat diabetic hindlimb ischemia. When administered as part of this formula, it helps improve blood flow and increases capillary density in diabetic mouse models. The plant contributes to the treatment's ability to regulate the VEGF signaling pathway, specifically by reversing the decrease of key proteins like VEGF and HIF-1α. Furthermore, its inclusion in the decoction assists in reshaping gut microbiota by increasing beneficial bacteria such as Akkermansia and Bifidobacterium. Through these combined mechanisms, Dioscorea hemsleyi plays a vital role in mitigating the vascular complications associated with type 2 diabetes.
Preparations
Dioscorea hemsleyi is prepared as part of the BuZangTongLuo formula (BZTLF), a traditional medicinal combination. This formula incorporates Dioscorea hemsleyi alongside six other medicinal plants and one insect leech to create a potent decoction. Within the context of this treatment, the inclusion of Dioscorea hemsleyi contributes to the overall efficacy of BZTLF in managing diabetic complications. Research indicates that this specific herbal formulation works to improve hindlimb ischemia by regulating the gut microbiota and activating angiogenesis. Therefore, Dioscorea hemsleyi serves as a key component in the preparation of the BZTLF therapeutic mixture.
