Shuanghe Decoction can assist in the treatment of posterior circulation ischemia, but it cannot completely cure it.

Shuanghe Decoction is a traditional Chinese medicine prescription. The main ingredients include peach kernel, safflower, angelica root, red peony root, chuanxiong root, earthworm, zombie silkworm, etc. It has the functions of activating blood circulation and removing blood stasis, unblocking collaterals and relieving pain. Posterior circulation ischemia refers to insufficient blood supply to the vertebral-basilar artery system, and patients will experience symptoms such as dizziness, nausea, vomiting, and tinnitus. Shuanghe Decoction can improve blood circulation, promote blood supply to the brain, and has a certain auxiliary therapeutic effect on relieving the symptoms of posterior circulation ischemia. However, the causes of posterior circulation ischemia are complex, including arteriosclerosis, hypertension, diabetes, cervical spondylosis and other factors. Shuanghe Decoction can only be used as an auxiliary treatment and cannot completely cure posterior circulation ischemia. Patients also need treatment for specific causes, such as controlling blood pressure, blood sugar, and treating cervical spondylosis.
