Here is another adenium that had branch damage because it tumbled off a cart and landed on it's head!
The result was an area that healed, but left an area that rot could invade in the future.
Scraped
Treated
Here is a picture of the product. It's a food product from Thailand and a little hard to find. I was given this White Limestone Paste from a friend who owns a Vietnamese restaurant.
I hope that this is helpful.
