In fact, cultivators themselves also have methods to extract the most effective components from certain medicines through the use of spiritual power.
However, such methods have high demands on the cultivator, and the extracted components are not used directly on the body. If used in alchemy, the extracted components would be quite unstable, increasing the failure rate of refining the Elixir, and even if successful, it might lower the quality of the Elixir.
Therefore, many alchemists prefer to find better materials rather than extracting components from medicines using spiritual power.
Moreover, if a cultivator's method is used for extraction, and the spiritual power of the cultivator is incompatible with the attribute of the materials, the materials would be destroyed.
