Hello, there were few brands of mud moxibustion in previous years. Generally, there are wax mud from Yuejia Caotang, black mud from Grandma Liang and mud moxibustion from Qiu Tiandao. These three brands are better. At present, many manufacturers of essential oils have begun to produce mud moxibustion, mostly using paraffin wax and Chinese medicine residue, which is low in cost, irritating in taste and low in price, disrupting the market. You can't tell from the words alone. I suggest you choose old brands when choosing, and then compare them with each other, instead of choosing new brands. I hope my answer can help you.
