1 The mitral valve-between the left atrium and the left ventricle. 2  The tricuspid valve-between the right atrium and the right ventricle. 3  The pulmonary valve-between the right ventricle and the pulmonary artery (the main artery that takes blood from the heart to the lungs to collect oxygen).
Quoted: 0 Post(s). Mineral oil is not the same as Castor oil--mineral oil is a petroleum product and castor oil is a vegetable oil from the castor bean (seed). Mineral oil works as a laxative because it oils everything up, the castor oil causes cramping and works as a laxative that way. So like mentioned above, the mineral oil won't have the same action.
Castor oil is good to treat styes (oil gland infections found on the eyelid), apply a small drop with a fingertip 2-3 times a day. Castor oil is a natural emollient and stimulates production of collagen and elastin, which hydrates the skin making it appear smoother and softer. Great when used for wrinkles and age spots. The high vitamin E content in castor oil is excellent for brittle nails and ragged cuticles.
