Castor oil, which comes from the castor bean plant, is a well-known natural medicine that can be used for many things. Over the years, this oil has been used to do many things, from helping hair grow to relieving constipation. But have you ever thought about how to make castor oil at home?

Read this blog post to learn how to make castor oil at home. Be aware that it takes a lot of work. It needs care and close attention to detail, and there are several steps to it.

Gathering Your Supplies:

You’ll need to get the necessary tools and ingredients before you start. Here is a list to help you begin:

  • Castor beans: Find castor beans that are whole and raw. Do not use broken or discolored beans.
  • Baking sheet: A big baking sheet is needed to place the beans on to roast.
  • Blender or mortar and pestle: To make a smooth paste out of the beans.
  • Large pot: A pot that’s big enough to fit the water and bean paste.
  • Strainer: A fine-mesh screen will separate the oil and plant matter.
  • Cheesecloth or cheesecloth bag: For additional straining.
  • Heat-resistant container: The final castor oil should be stored in a glass jar or a stainless steel container.

Step-by-Step Guide on How to Make Castor Oil at Home:

1. Roasting the Beans

Set the oven temperature to 350°F, which is 175°C. Place the castor beans on a baking sheet so they are all the same size. Roast the beans for 10 to 15 minutes, turning them now and then, until they turn a light golden brown color. Watch out because you don’t want them to burn. Cooking the beans loosens the oil inside, making it easier to get out later.

2. Grinding the Beans

Wait until the roasted beans are completely cool. Then, make a fine powder. A strong mixer works well for this step. If you don’t have a mixer, you can use a mortar and pestle instead, but it will take more work. The goal is to make a smooth paste that can easily let the oil out.

3. Extracting the Oil

Combine the ground bean paste with water in a big pot until it is covered by approximately one inch. Bring the mix to a boil, lower the heat, and let it cook for 30 to 45 minutes, stirring now and then. It will cook, and the oil will rise to the top.

4. Separating the Oil

Make sure the blend is completely cool. The oil and water will easily separate after this. Skim the oil off the top with a spoon after it’s cool. A turkey baster can also be used to get rid of the oil.

5. Straining the Oil

Wrap a sieve or bowl in cheesecloth and place it over the bowl. Run the oil through the strainer to get rid of any bean bits that are still in it. After this step, the oil will be clean and free of debris.

6. Simmering Away the Water

One more step is available here: If you see water drops in the oil, you can clean it even more by slowly simmering it over low heat. Pure castor oil will stay after the water disappears. Keep an eye on it, and don’t let it get too hot.

7. Storing Your Castor Oil

Put the clean castor oil into a glass jar with a lid that fits tightly on top. Write the date of creation on the jar. Keep your homemade castor oil somewhere cool and dark. Most homemade castor oil can be kept for about a year.


  • For the safety of your skin, wear gloves while handling ricin.
  • To maintain high-quality oil, avoid over-roasting the beans.
  • If the bean mixture appears to be too short, boil it for an additional minute or two to increase the oil yield.
  • You can use the cheesecloth more than once, but make sure you wash it well between times.


Making castor oil at home is fun and useful for people who like to do their own things. The time investment and safety precautions are important to keep in mind, though. For some people, it might be easier to buy high-quality castor oil from a trustworthy source. If you decide to go ahead with this job, don’t forget to enjoy it and always put safety first.
