All I am to say is no hearsay but all a personal experience. When one is stung by one of the above, all one has to do is to find a fig tree, which are sometimes common near the shore, in the case of jellyfish, and cut a fig if in time of fruiting, or a leaf or a small branch, and cover the red point of the sting, with the milk that oozes from the part of the tree, whether it is a fruit, or a leaf or a twig. As soon as the milk touches the sting, the burning stops, but afterwards, one has to wash his hands from the milk as the milk is very irritating to the eyes if touched.
Once, after a night of an untreated sting, a blister, three millimetres wide and some two centimetres long, grew on my forearm. As I was passing near a fig tree, I decided to touch half of the blister with the milk of the fig tree.
To my astonishment, the part touched, the blister disappeared, in about a minute. When I saw the result, I decided to return to the tree and touch the rest of the blister with the milk. Wonder of wonders, all the blister and everything disappeared.
