Castor oil, which comes from the castor bean plant, has been used for hundreds of years to treat a wide range of illnesses. Drinking castor oil is a common practice, particularly for its laxative properties. But before you take it, it’s important to know both the possible benefits and side effects.

Benefits of Drinking Castor Oil with Hot Water

The best-known benefit of drinking castor oil is that it can help you go to the bathroom. Castor oil’s main ingredient, ricinoleic acid, works on the intestines to make muscles contract, which helps with bowel movements. It can be beneficial for occasional constipation relief.

Mixing castor oil with hot water makes it work better as a laxative. The heat might help break down the oil, making it easier for the body to take and speeding up the process. However, there needs to be more strong scientific proof to prove this claim.

If you drink castor oil, here are some other possible benefits, though more study is needed to confirm these effects:

Skin health: Castor oil draws wetness to the skin because it is a humectant. Castor oil may help keep skin moist and soothe dry skin when applied to the face.

Hair health: Castor oil has the potential to help dry the scalp and hair because of its hydrating qualities. Some people use it to grow their hair faster, but little scientific proof exists.

Anti-inflammatory properties: Castor oil might help with conditions like arthritis by reducing inflammation, but more studies are needed.

Side Effects of Drinking Castor Oil

Dehydration: Castor oil has a strong cleansing effect that can make you lose too much water and dehydrate if you don’t drink enough. When you use castor oil as a cleanser, you need to drink a lot of water.

Abdominal Cramps: Some people may get stomach cramps or other problems after drinking castor oil. It usually happens because it makes it hard to go to the bathroom.

Nausea and Vomiting: It’s possible for some people to feel sick or throw up after eating a lot of castor oil because it has a strong, unique taste.

Diarrhea: If you use too much or the wrong amount of castor oil, it can cause diarrhea, which can cause electrolyte issues and other problems.

Important considerations:

  • Dosage: To avoid health problems, follow the dose instructions on the bottle or talk to a doctor before drinking castor oil. If you take too much, the side effects may get worse.
  • Not for everyone: Not everyone should use castor oil. Castor oil shouldn’t be drunk by pregnant women, people with specific health problems, or kids. Before using it, it’s always best to talk to a doctor.
  • Short-term use only: Castor oil is only meant to be used occasionally and briefly. A doctor or nurse should help people who have chronic constipation.

Uses of Drinking Castor Oil

In addition to its internal use for digestive problems, castor oil has various external uses, including:

Skin Moisturizer: You can put castor oil on dry skin to moisturize and soothe it.

Hair Care: There is a belief that massaging castor oil into the scalp will enhance the condition of the hair and stimulate hair growth.

Joint Pain Relief: Some people put castor oil packs on their joints to ease pain and swelling.

Additional tips:

  • If you don’t like the way castor oil tastes, you can hide it by mixing it with juice or another sweet drink.
  • Castor oil can cause dehydration. Therefore, it’s important to stay hydrated after eating it.
  • Stop using castor oil and visit a doctor if you have serious adverse effects from consuming it.


Castor oil mixed with hot water can be good for you in some ways, especially as a natural laxative for constipation. But it’s important to be careful and use it only in small amounts because it can have side effects like thirst and stomach pain. Before using castor oil, you should always talk to a doctor or nurse, especially if you are pregnant or already have a health problem. Also, think about other ways to improve digestive health, like eating a healthy diet and drinking plenty of water.


What should I do after drinking castor oil?

Castor oil stimulates your intestines, so you should anticipate numerous bathroom excursions within a few hours. After you drink it, plan to stay close to home for a while.

Resting easily is best because you might feel cramping or pain.

What is the best time to drink castor oil?

When you're not hungry, right before bed at night is the best time to drink castor oil. This lets the oil work its way through your body overnight, and when it does start to work, you'll be close to a bathroom. Please do not take it right before a big event or when you need to be elsewhere.

What should I eat after drinking castor oil?
