What is the difference between Xueshuantong injection and Shuxuetong injection?

The difference between Shuxuetong and Xuesaitong is obvious. The names seem similar, but the raw materials are far apart. Shuxuetong is the extract of earthworm and leech, while Xuesaitong is the extract of Panax notoginseng, a plant medicine that promotes blood circulation. Which is better to say? The effect is similar, but it can be said that Shuxuetong is far less widely used than Xuesaitong. Generally, clinical medication is more, and the medication experience is more abundant and reliable. Now the hospital is using Luotai Xuesaitong injection from Kunyao Group, which has few adverse reactions and is a time-tested old medicine.
