Uses
Annually, 270,000–360,000 tonnes (600–800 million pounds) of castor oil are produced for a variety of uses. Food and preservative
In the food industry, food-grade castor oil is used in food additives, flavorings, candy (e.g., polyglycerol polyricinoleate in chocolate), as a mold inhibitor, and in packaging. Polyoxyethylated castor oil (e.g., Kolliphor EL) is also used in the food industries.In India, Pakistan, and Nepal, food grains are preserved by the application of castor oil. It stops rice, wheat, and pulses from rotting. For example, the legume pigeon pea is commonly available coated in oil for extended storage. Traditional medicine
Use of castor oil as a laxative is attested to in the circa 1550 BCE Ebers Papyrus, and was in use several centuries earlier.Although used in traditional medicine to induce labor in pregnant women, there is no clinical evidence that castor oil is effective for dilating the cervix or inducing labor.According to the American Cancer Society, "available scientific evidence does not support claims that castor oil on the skin cures cancer or any other disease." Skin and hair care
Castor oil has been used in cosmetic products included in creams and as a moisturizer. Small amounts of castor oil are frequently used in cold-process soap to increase lathering in the finished bar. It also has been used to enhance hair conditioning in other products and for supposed anti-dandruff properties. Coatings
Castor oil is used as a biobased polyol in the polyurethane industry.
Bifascicular block is a conduction abnormality in the heart where two of the three main fascicles of the His/Purkinje system are blocked. Most commonly, it refers to a combination of right bundle branch block (RBBB) and either left anterior fascicular block (LAFB) or left posterior fascicular block (LPFB), with the former being more common.Some authors consider left bundle branch block (LBBB) to be a technical bifascicular block, since the block occurs above the bifurcation of the left anterior and left posterior fascicles of the left bundle branch. Diagnosis
Diagnostic criteria:Clinically, bifascicular block presents with one of two ECG patterns:
Right bundle branch block (RBBB) with left anterior fascicular block (LAFB), manifested as left axis deviation (LAD). RBBB and left posterior fascicular block (LPFB), manifested as right axis deviation (RAD) in the absence of other causes. Treatment
In those with bifascicular block and no symptoms, little with respect to treatment is needed. In those with syncope, a pacemaker is recommended. References
