Cactus is full of treasures. I keep a pot of cactus on the balcony of my house. My grandma often cuts a piece of it with scissors and rubs it on her hands. It can protect the skin and make it better. And sometimes when the weather is too cold, your hands are easily cracked by the wind. Applying cactus slurry to your hands can prevent cracking.
