Treating First-Degree Burns — Topical Herb Reference

Contraindications — Read Before Using

• Chaparral — removed from this card entirely — do not ignore: The source pin recommended chaparral specifically for "more intense cases" with no caution at all — backwards logic. Chaparral's documented hepatotoxicity risk is mainly tied to internal use (the FDA has advised against taking it by mouth at all), and topical use has a real traditional history with a lower but not zero risk profile (contact dermatitis in sensitive people). The actual problem is the pairing: worse burns mean more compromised skin, and more compromised skin means more of whatever's applied gets absorbed into the bloodstream — the exact wrong direction to reach for a stronger, less-studied herb. Removed rather than caveated, since a home first-aid card isn't the place for a call that should sit with a trained herbalist.
• Comfrey leaf — removed from this card entirely — do not ignore: The source pin listed comfrey leaf as a topical option for burns. Comfrey contains pyrrolizidine alkaloids that cause real liver damage, and the mechanism is exactly the skin-barrier problem above: broken or damaged skin absorbs far more of it than intact skin does. Every real safety source on comfrey says the same thing — never apply it to broken skin, wounds, or burns, full stop. A card about treating burns is precisely the wrong place for an herb whose own safety rule excludes burns by name. Not a caution, a removal.
• "Mild radiation sickness" language — corrected: The source pin described a bad sunburn using radiation-sickness language. That borrows the vocabulary of acute radiation syndrome (a real, unrelated, far more serious medical condition) to describe a sunburn — fear-inflating and inaccurate, not just casual phrasing. Corrected to plain "severe sunburn."
