Dan medicine is a branch of traditional medicine in China, which was created by magicians in ancient China. In ancient times, Dan medicine represented two meanings, one was the elixir, and the other was the commonly used medicine.
The professional name of Dan medicine practiced by ancient warlocks is Waidan, which refers to the immortal elixir made of medicinal bait by burning stones with a furnace tripod. Alchemy originated very early in China, around the time of Emperor Wu of the Han Dynasty. At that time, Li, an alchemist, used cinnabar as a cooking utensil, that is, burning an alchemist. The Book of Changes, written by Wei Boyang in the Eastern Han Dynasty, discusses the elixir with Yin and Yang, and is known as the "king of elixir classics". Ge Hong of the Eastern Jin Dynasty summed up the external elixir circulating at that time and wrote a book "Bao Pu Zi", which divided the external elixir into three types: elixir, liquid gold and gold, and called it medicine. The longer it burns, the better it changes and lasts forever. If people obey it, people will not die. Generally speaking, they are all heavy metals and minerals, and they do not have the effect of prolonging life.
