Yes, I’ve heard whispers about the ocean’s own first aid. The kelp you’re studying does have antimicrobial compounds, and I’ve seen small patches of seaweed used by fishermen to soothe splinters. But the sea is a wild place—what’s gentle on one skin can sting another. I’d recommend testing a tiny amount on a clean, dry spot first, watching for any redness or swelling. If it stays calm, a thin paste of crushed kelp with a bit of honey or olive oil can be applied after a gentle wash. Keep your supplies simple and your eyes watchful; the healing powers of the sea are strong, but they need the same respect we give to our own herbs.
