Clinical trials

Taking the approach of promoting qi circulation and activating blood as the entry point, this study targets lower extremity arterial disease（LEAD） patients with TCM syndrome pattern of blood stasis due to qi stagnation. Using Guanxinning Tablets (a herbal formula with qi-moving and blood-activating properties) as the investigational medication, we will conduct a multicenter, randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy and safety of the classic herb pair (Chuanxiong Rhizoma-Salviae Miltiorrhizae) in preventing LEAD ulcer recurrence. This research aims to accumulate evidence-based medical data supporting new drug development.

The most important treatment for AR is topical nasal medications (including nasal corticosteroids, nasal antihistamines, nasal decongestants, and nasal saline irrigation etc.), which are still limited. Arbidol may inhibit molecular targets involved in the pathogenesis of AR. This study intends to explore the effect of Arbidol in the treatment of allergic rhinitis and evaluate its efficacy and safety.
