北京同仁堂 珍珠亮白牙粉 清涼薄荷香 50 克

Knowing TongRenTang is the renounced brand in Chinese medicine, I was curious about this cleaning powder. So I bought one to try. I've been using this powder for about two weeks. So far, I haven't noticed anything significant. However, it does feel very clean after using it. The taste is very mild and fresh. No complains. But I think normal toothpaste does the same thing (maybe).
