This response appears to discourage “holistic” treatments with “no herbal products have been shown to be effective for treating cancer”, despite a large body of evidence to the contrary (like green tea reliably slowing metastasis, and garlic for slowing tumor growth by immune system support + a bunch of other pathways (GARLIC IS SO OP)).
As far as I remember “effective for treating cancer” usually means an increase in cancer survival time. Drugs that do show some slowing of tumor growth but where the patient still dies at the same time are not considered effective for treatment of cancer.
There are many poisons that you can give people that slow tumor growth but that don’t increase patient lifespan, do it makes sense to define “effective for treating cancer” that way.
