Nutrients loss

One of the castor oil side effects is that the intake of the oil for a period over a week may induce potassium and fluid loss. The daily dose of 15-60 mL may prevent the digestion of some valuable nutrients and may lead to dehydration.  Strictly follow the instructions given by your doctor or pharmacist or written on the label.

Danger for pregnant women

Castor oil is known for its effect to induce labor in women. Pregnant women take the oil to go into labor when their delivery due date is over. The ricinoleic acid of the oil stimulates the contraction of bowel muscles and as a result it induces labor. However, pregnant women shouldn’t use castor oil without the doctor’s supervision. Moreover, it is dangerous to take castor oil for women with the pregnancy period of less than 40 weeks. The oil may induce labor. It is unknown whether castor oil enters the breast milk so avoid taking castor oil in case you are breast-feeding. Read also about tea tree oil for pregnant women.
