Of course I made it myself. People's Chinese medicine machines fry unused drugs every day. This will lead to the risk of cross-linking. Once cross-linked, it will definitely affect the efficacy. Fire yourself and you won't have this problem. Will it be troublesome to fire yourself? In fact, the current domestic frying pan is very professional, fully automatic, subdivided into one frying and two frying. Four bowls of water can be cut into 1 bowl of water, three bowls of water can be cut into 1 bowl of water and two bowls of water can be fried into 1 bowl of water. We know that traditional Chinese medicine can't touch metals, and metals will affect the efficacy. It seems that many frying pans on the market are metal heating plates, which are in direct contact with medicinal materials. The all-glass health pot I am using now has the above automatic function. What reassures me most is that this pot contains no metal at all.
