Query: Chinese tooth pastes

There are a few Chinese toothpastes for sale in the market. The only two I use are LMZ and the one with Ginkgo. I started with the one with Ginkgo. It helped me to manage my gum problems, which I spent thousands of dollars in gum surgery and cleaning in the periodontist offices about 10 years. Maybe I do a better job in taking care of my teeth or the effect of the Chinese toothpastes, one way or the other, my gum problems are gone. I could not find the one with Ginkgo a few years ago, so I changed to LMZ. Now I use whichever I can find in the Chinese stores. I saw that they are for sale on the internet today. Good news to me, I do not have to travel to Chinatown just to buy them anymore.
