What is Black Seed Oil?

As well as castor oil, black seed oil has a very long history! It was once used by Egyptians and more generally in the middle east as well as in India. Recently, this oil is becoming more and more popular and its reputation is already well established! Black seed oil traveled through time and contributed to the well being of generations of people.

Black seed oil is extracted from black cumin (Nigella sativa), an annual flowering plant that provides tiny seeds that are beneficial to your health. With a spicy smell, an orange-brown color, and a thick and creamy texture, this oil is a natural delight for your beauty as well as your overall health.

The seed and the oil

This oil is particularly rich in vitamin F (linoleic acid), in oleic acid and palmitic acid. It is relatively sensitive to oxidation, so it is preferable to store it in a protected environment under 68°F (20°C). 

It’s one of the only vegetable oils that naturally contains essential oil. This makes its active properties even more powerful (black seed oil cures plenty of skin diseases and possesses immunostimulant, antiseptic, anti-inflammatory properties). There are more than 500 studies proving the incredible effects of the black seed oil!

Benefits of Black Seed Oil

There are plenty of helpful black seed oil uses including:

For your skin:

  • Purifying, antiseptic and healing, it effectively fights against eczema and skin fungus.
  • Antioxidant and very nourishing, it strengthens skin and acts as an anti-aging treatment.

For your hair:

  • Fight against dandruff.
  • Nourishes dry and brittle hair.

For your well-being and health:

  • Anti-inflammatory, it is also used to relieve the joints.
  • Orally, it strengthens the immune system and helps fight against allergies and asthma.

I have not been using the combination, so it’s hard to tell you the results in the long run. However, this oil seems like a great alternative! It is efficient and smells great… I can only recommend it to you!

It seems that its benefits are more targeted toward health than beauty, so it will then depend on what you are looking for.

Black Seed Oil and Castor Oil Recipe: DIY

Here are some wonderful castor oil and black seed oil recipes:

Purifying face mask

Mix the following ingredients together:

  • A tablespoon of black seed oil
  • A teaspoon of castor oil
  • 1 tsp of olive oil
  • 1-2 tsp of honey (mountain honey is my fav)

Apply it on your face and let it sit for 20 minutes. Rinse well and enjoy it! oil face pack

Aromatic bath for your hair (purifying, promotes regrowth)

Mix the following oils together:

  • 3 teaspoons of black seed oil
  • 1 tbsp of castor oil
  • 1 tablespoon of coconut oil (see article)
  • 1-2 tsp avocado oil

Apply the mixture on your scalp (from the roots to the tips) and let it sit preferably all night by taking special precautions to protect your pillow and sheets.

Black seed oil for your health

  • One to two tablespoons a day orally will help you strengthen your immune system and improve your digestive system. It’s a little bit contrary to castor oil taken internally as it provokes a (too) powerful purification of the digestive tract if you know what I mean. Black seed oils act smoothly for your wellbeing.

  • You can either drink it on its own or add some honey for a different taste.

  • Avoid drinking additional liquids right after, it’s important to let the black seed oil act.

My Recommendation

My favorite BSO
See it here on Amazon!

Black seed oil is not a cheap oil but it comes with its perks, it works for your health! Here is my recommendation for a quality oil:

Final Thoughts

There is more to black seed oil than meets the eye. It’s a wonderful oil that is well worth knowing.

The black seed oil has complementary effects with castor oil and that’s why I was so happy to add it to my selection of natural products. As usual, make sure to use an oil of premium quality (organic, virgin cold-pressed oil guaranteed extracted without the use of any chemicals). It’s especially important since this oil really reveals its potential once taken internally.

    • Hi there Berry, thanks for your comment! Just be careful when administering black seed oil to your baby, and especially avoid ingesting castor oil. You can easily administer some oil by applying to your finger and swabbing gently on your baby’s gums twice a day. BSO is great for immune health, but I would recommend asking your baby’s doctor before giving too much quantity wise.

  1. Hey brittany can you use Jamaican black seed and Jamaican castor on a newborn baby hair and skin for eczema and can you use it while you’re breastfeeding will it harm the baby

  2. Very useful sharing. Is mixing apple cider vinegar into the black seed oil- honey combination for oral consumption ok? The mixture tastes this way. What are the benefits of this mixture ?

    • Hey Naaz! Great question. Castor oil and honey is very beneficial for your face, on hair, skin, even on burns! Black seed oil is known for being great for your wellbeing when consumed orally, although you can of course use it as a purifying face mask or hair growth mask. The apple cider vinegar is a splendid home remedy for sore throats, so this mix (with honey) will soothe and naturally disinfect if you’re coming down with a cold. I hope this helps! Thanks for your question!

  3. Hello
    Im 58 and I have natural curly hair that is thinning bad on top and it grows very slowly. I got a bad haircut last week and it was cut way to short. I’ve been reading about theblack seed oil and castor oil in your article. I want to buy the black seed oil you recommend . Is there a product I can trust that has both ingredients in them together to maje it easier for me to use on my hair?
    What do you recommend to help my hair grow?
    Thank you .

    • Hi Maria!
      Thanks for reaching out to me with your comment 🙂 Yes black seed oil and castor oil are a great combo. It would actually be more beneficial to you to buy both separately and just combine them (it’s really easy to mix). This will guarantee the quality of both oils. A combined product isn’t ideal. You can do them easily at home and it will be easy to apply on your hair. You can read more about my castor oil hair mask or dry hair recipes for more ideas about mixtures you can create. Don’t be shy to get creative! There are so many possibilities. Coconut oil, manuka honey, avocado, egg, and of course don’t forget castor oil!!! 🙂 Thank you for reaching out and please do let me know if you have any other questions. I’m happy to answer them!

    • Hey Ty,
      Thanks for your comment. True, the aroma can affect people differently, but if you want to outweigh the spicy scent from the black seed oil, try to add some vanilla essence or essential oils. Just be careful not to use too much (too many drops) because essential oils are quite strong. You can read more about them here. Thanks for dropping by!
