What words are restricted on Amazon listings?
Amazon restricts medical claims (cure, treat, prevent), superlative claims without proof (best, #1), guarantee language (lifetime guarantee), and category-specific restricted terms (FDA claims on supplements, EPA claims on cleaning products). Using them can suppress the listing or trigger account review.

The obvious ones
Cure, treat, prevent, heal, diagnose (medical). Best, #1, top-rated, most-recommended (superlative without proof). Lifetime guarantee, unconditional refund (implied promise beyond Amazon's own policy).
If a claim triggers a takedown, the ASIN appears in the listing issues view with the reason attached.
The category-specific ones
Supplements: FDA claims. Cleaning: EPA claims. Electronics: safety claims that require certification. Kids and baby: safety claims without evidence.
Frequently asked questions
Are these words hard-blocked?
Some are hard-blocked at listing creation. Others survive until enforcement flags them.
Can I say 'natural' or 'organic'?
Yes if backed by certification. Organic without USDA certification is a compliance risk.
What if a competitor uses banned words?
Report the listing through Report Abuse; enforcement is uneven but does happen.
