Using venomous marine organisms as a therapeutic might not be altogether a bad idea. With a respect of course. I find venom therapy interesting and have used bee venom(apitherapy), on and off for the past few years... But something has gone AWRY with these nematocysts!
How would you even know if you used a product that has nematocysts in there?
I live very near where phosphate polluted fresh water meets the Gulf of Mexico(which is polluted also). I don't swim or even wade in streams anymore : (
Maybe nematocysts gone wild carry on the wind like pollen? Where they could land on you, or deliver a "barb" from a certain distance, rendering the skin more permeable to ???
Images are of discharged nematocysts that all came from directly off of my skin...
I found this photo online that's nearly identical, but still embedded in it's "target"!
This one has multiple cnidocysts running the length of it, and some, you can see, have discharged...
