Japan is NOT part of Asia according to some Japanese. Japan is separated from Asian continent by water, and some Japanese believe it's not part of Asia. If they say something like: We are building new factories in Asia, the phrase would explicitly mean We are building new factories in Asia, but outside of Japan.
Castor oil is used to treat constipation. It may also be used to clean out the intestines before a bowel examination/surgery. Castor oil is known as a stimulant laxative. It works by increasing the movement of the intestines, helping the stool to come out.
Castor oil is used as a laxative for constipation, to start labor in pregnancy, and to start the flow of breast milk. Some people apply castor seed paste to the skin as a poultice for inflammatory skin disorders, boils, carbuncles, pockets of infection (abscesses), inflammation of the middle ear, and migraine headaches. Castor oil is used topically to soften skin, bunions and corns; and to dissolve cysts, growths, and warts. It is also applied to the skin for osteoarthritis. Some women put castor oil inside the vagina for birth control or to cause an abortion.
