How much castor oil should you take to relieve constipation?

Castor oil is a powerful laxative that should be used with caution. The typical dosage for adults is 1 to 2 teaspoons (5-10 mL) taken by mouth once a day. However, the exact dose may vary depending on the individual and the severity of their constipation. Start with the lowest dose and increase it gradually if necessary.

It's important to follow the directions on the product label and talk to your doctor before taking castor oil, especially if you have any underlying medical conditions or are pregnant or breastfeeding. Castor oil can cause side effects such as nausea, vomiting, and diarrhea, and it can interact with certain medications.
