Butsu is a prefix derived from the verb buchi which literally means to hit but the usage of the prefix is a verb-intensifier. Kakeru in this context means to shower or pour. The word bukkake is often used in Japanese to describe pouring out water with sufficient momentum to cause splashing or spilling.
It is also useful for the healing of wounds and the formation of scar tissue. Therefore, people with wounds should eat ample amounts of amla, guava, lemon, orange, cranberry, strawberry, pineapple, kiwi fruit, broccoli, cauliflower, tomatoes, spinach, cabbage, and other food items that contain vitamin C.
To speed the healing of a burn, one home remedy is to eat foods rich in vitamins C and E or take 2,000 milligrams of vitamin C and 1,000 IU of vitamin E for a week or so after your burn. You can even break open a vitamin E capsule and apply it directly on the burn to help it heal and prevent scarring.
