Abstract

The invention discloses a diabetic peripheral neuropathy treatment medicine and a manufacturing method thereof. The medicine is mainly prepared from radix astragali, radix rehmanniae, rhizoma dioscoreae, angelica sinensis, cornus officinalis, cassia twig, salvia miltiorrhiza, lumbricus and leech. The medicine has efficacies of Qi tonifying, Yin nourishing, kidney tonifying, blood circulation promoting, stasis removing and meridian activating and has functions of reducing blood glucose, increasing microvascular diameter and blood flow volume, increasing sciatic nerve conduction velocity and increasing sural nerve tract area, myelin sheath fiber number and myelin sheath fiber density. The medicine can be used for treatment of diabetic peripheral neuropathy and has advantages of remarkable curative effects, quick action, short treatment period, safety and avoidance of relapse and side effects.

Description

technical field [0001] The invention relates to a medicine for treating diabetic peripheral neuropathy and a preparation method thereof, belonging to the technical field of medicines. technical background [0002] Diabetic peripheral neuropathy (diabetes peripheral neuropathy, DPN) is one of the most common chronic complications of diabetes, and is the main cause of disability in diabetic patients.
