Which source claims there are no known contraindications for using neem oil topically while breastfeeding?

Some product formulators

While authoritative health portals tend to advise caution or complete avoidance due to insufficient data regarding systemic absorption into breast milk, some entities involved in product creation hold a different view regarding external application. Certain product formulators suggest that topical application does not carry the same risk as ingestion. In some instances, these sources specifically assert that there are no existing, recognized contraindications—meaning no documented reasons to forbid—the external use of neem oil on a mother who is currently breastfeeding or pregnant. This perspective often rests on the premise that topical skincare involves very diluted forms compared to internal consumption or pesticide use.
