We use an Aloe plant for burns etc. I’ve read that freshly peeled potato skins are great for burns and preventing infection too. After a long day of arc welding I use to squeeze the juice from Potato skins in my eyes to heal the Ultraviolet flash burns.
one time, I was burned by cooking grease , I went to the pharmacy with a huge blister on my hand and wrist and asked them for advice on what to use, they told me to go to the E.R., I did not have insurance so i wanted to avoid that , I went home and cut open an aloe plant and taped it on my hand for 2 days, Not only did it prevent infection, It southed the burn/ blister after all was said and done I didn’t have a scar either. I was amazed and now I always keep a plant around.
Here is a good link on such things.
