No. Only chemicals.
Alchemists :)
Paracelsus introduced the concept of "disease" to medicine, however rejecting the idea that disease is a matter of imbalance and disharmony in the body. He claimed that disease is caused by agents outside the body attacking it. This was long before viruses and bacteria were discovered.Trimble, Russell, "Alchemy," in The Encyclopedia of the Paranormal edited by Gordon Stein (Buffalo, N.Y.: Prometheus Books, 1996), pp. 1-8.

Alchemy was a supposition held before modern science developed, that elements could be transmuted, ie to turn lead into gold, or similar, by chemical means. The alchemists never succeeded and we know now that this is impossible. The nature of an element depends solely on the make up of its nucleus, primarily on the number of protons it contains. We know now that this can be altered by radioactivity or by exposing a material to a neutron flux in a reactor, so transmutation does occur but only by means that the alchemists never knew about.
Alchemists could not turn metal into gold because gold is an element.
Most medieval alchemists believed there were four elements: fire, earth, air, and water. Their idea of elements was a bit different from that of modern chemists. They knew about some chemical elements, including gold, silver, copper, iron, mercury, and sulphur, but they did not know they were elements. They discovered some elements, including bismuth, antimony, and arsenic, but they did not know they were elements either. All of these elements, and everything else in nature, they believed, was made up of varying combinations of fire, earth, air, and water.
Alchemists were the first chemists. Using chemicals and magic, they attempted to turn lead into gold, and to create the philosopher's stone.

Air, water, fire, earth.
It came from the alchemists in the Middle Ages because these elements were unchanged by fire.
Putrefactio meant decay. The alchemists believed in breaking down matter to it's base elements, either through decay of by using acid.

most Chinese people don't know it. I guess only Chinese historians know...
Cerium was not known by alchemists.
Nothing. They didn't have the technology at that time to know about the existence of atoms.
