Castor oil has been used for centuries to promote a healthy pregnancy naturally. It can stimulate digestion, reduce inflammation, and relax the uterus. Internally taking castor oil daily after meals can support gut health. Topically applying castor oil can help alleviate lower back pain and cramps. However, it's essential to follow safe dosages and warnings to avoid adverse effects. Consult a healthcare professional if you're pregnant and taking medication or have any allergies.
