It must be Lion, with more than 90% content, which belongs to nature. Although Yangshengtang is "natural", its content is less than 40%, and it is doped with many other ingredients. Sorry, I made a mistake just now. I thought you were talking about VE, but I don't think it's good for Yangshengtang, because all the doctors in the hospital prescribe Lion brand things for pregnant women, and there are no side effects.
