How to Make Your Own Primrose Oil at Home

Primrose oil is extracted from the seeds of the evening primrose plant. It is prized for its high concentration of gamma-linolenic acid (GLA), an omega-6 fatty acid with anti-inflammatory properties. While primrose oil supplements can be purchased, it is also possible to make your own oil at home. Here is a step-by-step guide on how to make primrose oil:

Ingredients

• Evening primrose seeds – These contain the valuable oil You’ll need around 4 cups of seeds

• Carrier oil – A neutral oil like grapeseed or olive oil to help extract and dilute the primrose oil.

• Cheesecloth – To strain the finished primrose oil.

• Glass jar – For storing the finished oil

Step 1: Obtain Primrose Seeds

You can either grow your own evening primrose plants and collect the seeds when ready or purchase organic, non-GMO primrose seeds from a reputable supplier. The seeds are found inside seed pods that turn brown and papery when mature in mid to late summer.

Collect the ripe seed pods and remove the tiny, black primrose seeds inside to amass the 4 cups needed to make a good quantity of oil. Pick only undamaged, healthy looking seeds.

Step 2: Dry and Clean the Seeds

Spread the seeds in a single layer on a baking sheet or tray. Allow them to dry at room temperature for 2-3 days until crisp and brittle. Shake the tray occasionally to ensure even drying. Once fully dried, the seeds will easily crumble between your fingers.

Remove any debris, dirt or bad seeds. Transfer the dried seeds to an airtight container until ready to use. Proper drying is vital for the oil extraction process.

Step 3: Grind the Seeds into a Powder

Place the thoroughly dried evening primrose seeds into a coffee grinder, high-powered blender or food processor. Grind them on high power into a fine powder. Take care not to overgrind into a paste. The powder should flow freely.

You want an ultra-fine powder to maximize the surface area for oil extraction. Sift to remove any large pieces remaining after grinding.

Step 4: Combine with Carrier Oil

Transfer the ground primrose seeds to a small slow cooker or double boiler. Add 1 cup of carrier oil like olive or grapeseed oil for every 1/4 cup of seed powder. The oil helps extract the primrose oil from the powder.

Stir thoroughly to fully incorporate the powder into the oil. The mixture should have a wet, sand-like texture. Add more carrier oil if needed to achieve this.

Step 5: Infuse on Low Heat

Heat the seed-oil mixture over low heat in the slow cooker or double boiler, maintaining a temperature of around 100°F to 115°F. Do not allow the oil to reach temperatures over 140°F.

Gently stir the infusion every 30 minutes. The low steady heat draws the valuable oils out of the powder without damaging their nutrients.

Step 6: Strain Out the Oil

After 4-6 hours, remove the mixture from the heat and allow it to cool to room temperature. Next, carefully strain it through a fine mesh strainer or cheesecloth to separate the oil from the spent powder.

Gather up the corners of the cheesecloth and squeeze gently to press out all the oil. Avoid small seed particles in the finished oil.

Step 7: Store in an Airtight Container

Transfer the fresh primrose oil into a sterile glass jar or bottle. Make sure the container has an airtight lid or stopper. Store in a cool, dark place like the refrigerator. The oil will keep for up to one year if properly stored.

Shake the bottle periodically to maintain an even consistency as the oil may solidify slightly when cold. Now you have a high quality, homemade primrose oil ready for use!

Tips for Making Great Primrose Oil:

• Completely dry seeds before grinding to prevent mold growth

• Use a neutral carrier oil like grapeseed or light olive oil as the base

• Maintain very low heat while infusing to protect nutrients

• Grind seeds into the finest powder possible for best oil extraction

• Stir the infusion frequently while heating

• Make sure to squeeze cheesecloth well so no oil goes to waste

With the proper ingredients, technique and patience to allow for long infusion time, making your own evening primrose oil at home is both simple and rewarding.
