Castor oil—pressed from the seeds of the Ricinus communis plant—has been treasured for centuries thanks to its powerful health, beauty, and therapeutic benefits. Rich in fatty acids, antioxidants, and natural anti-inflammatory compounds, this golden oil is now a favorite in natural wellness routines around the world. Whether you want to strengthen your hair, hydrate your skin, or soothe common ailments, castor oil is a versatile remedy worth having at home.

Below, you’ll learn how castor oil is made, the safest extraction methods, and the most effective ways to use it in your daily routine.

How Castor Oil Is Extracted

Although commercial castor oil is widely available, many natural-health enthusiasts appreciate extracting it themselves to ensure purity and quality. Two traditional methods are commonly used:

Method 1: Cold-Press Extraction

Best for preserving nutrients and achieving premium quality

Materials Needed

• Clean, dried castor seeds

• A manual or electric oil press

• A glass jar with a lid

Instructions

1. Clean the seeds thoroughly and ensure they are completely dry.

2. Crush the seeds with a mortar or grinder until they form a coarse paste.

3. Place the paste into the oil press and begin extracting the oil.

4. As the oil flows out, collect it in a clean glass jar.

5. Filter the oil through fine cloth or a strainer to remove shell fragments.

6. Store the filtered oil in a sealed glass container in a cool, dark place.

Cold-pressed castor oil retains most of its vitamins, natural antioxidants, and fatty acids, making it ideal for skincare and haircare applications.

Method 2: Heat Extraction (Boiling Method)

More accessible and effective for small, home-based batches

Materials Needed

• Castor seeds

• Water

• A pot

• A strainer

• A clean jar

Instructions

1. Crush the seeds into a coarse mixture using a mortar or blender.

2. Place the crushed seeds into a pot, add water, and mix well.

3. Boil the mixture until the oil separates and floats to the surface.

4. Skim the oil carefully with a spoon and transfer it to another container.

5. Filter the oil to remove impurities.

6. Allow the oil to cool and then store it in a sealed glass jar.

This method produces a slightly thicker oil but is very convenient for beginners.
