I accidentally found a plant that can cure diseases. I want to make it into a potion type and apply for a patent. How can I do it?

You can't apply for a patent for the plant you found. It originally exists in nature.

You can apply for a patent if you use it as a raw material and make your own potion to form a formula, but it takes a lot of experiments and tests to make the medicine ready for use, so it is difficult to realize one's ability. It is recommended to seek cooperation with medical resources.
