Can dried and decayed leaves, flowers, and other kinds of wastes heal diseases like cancer?

We need this for Science fair. What specific kinds of waste products are responsible for healing?

Can dried and decayed leaves, flowers, and other kinds of wastes heal diseases like cancer?
Due to the phrasing of the question, I'm going to say no. Most medicines and drugs are refined forms of substances found in plants, but the refined product is almost always superior. The dried and decayed description sounds a bit like psychic healing, which in fact heals nothing.


If you're specifically looking for plant waste products that are beneficial to people, try oxygen. It doesn't cure cancer though.
Reply:I doubt cuz scientists have probably thought of that.
