This may sound so disgusting, but it has worked for my brother and i.
For dry rough coughs:
Slice an onion and boil it together with honey in a small pot. Let it cool or become warm, then mix in some lemon. And Serve
It's also good to have an aloe plant around, prefer the African aloe plant, but it all works the same. If you get burned you just put on some aloe and you don't remain with a hideous scar.
ALoe is also good for teh hair, although the smell isn't pleasant.
