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.
Amino acids appear to help wounds heal faster. These can be found in foods such as chicken, egg whites, fish, brown rice, healthy nuts like walnuts and almonds or sunflower seeds. Some studies also indicate that boosting vitamin C in your diet as well as increasing your zinc levels can be helpful.
