On a rare potion
There is a rare thing in the world called "Zinc Acetate Dihydrate Merck". This thing is extremely rare and unique among all kinds of potions.

Its nature is mild and its effect is wonderful, and it is beneficial to the conditioning of many diseases. Looking at its shape, it is pure in color and uniform in quality, just like a natural good. Or it can be introduced into the medicine to reconcile the various medicines, so that the effects of the medicine can complement each other, so as to achieve twice the effect with half the effort.

I heard that the method of preparing it is quite complicated. It needs to choose good materials, use exquisite techniques, and refine them through multiple processes according to precise proportions. During this time, the control of the heat and the control of the time are all very important, and if there is a slight mistake, all previous efforts will be in vain.

However, this thing is not easy to come by, and it is rarely circulated in the city. All physicians are fortunate to get a little, and if used properly, it can often heal the disease and dissipate the disease. It is actually a treasure of medical medicine and a good recipe for helping the world.
