Castor Oil and Baking Soda | Treat Skin Naturally

Last Updated on

Hola everyone! So we have already mentioned the benefits of castor oil combined with other ingredients such as hemp oil or garlic, but what about castor oil and baking soda?

In this article, I would like to tell you about a combination that seems to be little known but nonetheless very interesting: castor oil and baking soda. Let us discover why and how to benefit from the virtues of these two natural ingredients!

Castor Oil – Pure or as a Mix?

Castor oil has become one of the leading products of natural cosmetics. Used since antiquity, it is a versatile remedy that has proved its worth. The testimonies of its positive effects, on the hair and the skin in particular, are numerous! As for its uses, you will find on my site plenty of recipes to make the most of its virtues.

Since castor oil is rather thick and viscous, it is often recommended to dilute it with another carrier oil, depending on the area to be treated. However, it is of course possible to apply it pure, especially on the skin, eyelashes, eyebrows, nails or hair.

Do not hesitate to apply it on itchy skin or on areas prone to dryness, such as the hands and the feet.

To mix, you can opt for jojoba oil, olive oil or coconut oil. This last one is very interesting, mixed half and half with castor oil, to make a mixture that you can let soak in all night to treat dry or frizzy hair (for example).

Of course, you can also add essential oils to castor oil, to make a DIY shampoo, scrub, deodorant, etc.

Why Baking Soda?

Baking soda is a staple ingredient. One must keep in the closet or pantry at all times!

The combination of castor oil and baking soda may seem odd at first. Yet, this is a very effective base in home cosmetics. Natural and economical, you probably know baking soda in the form of a white powder.

It is used especially for home care products such as cosmetics, food, gardening, but also for healing.

Biodegradable, sodium bicarbonate, or sodium, does not have any harmful effects. It only has amazing virtues and it is always good to have some at home.

It is truly a handy powder. Being effective against bad odors and sanitizing is just one of it’s many benefits. In cosmetics, baking soda is used especially when brushing teeth and can be used in the composition of a homemade deodorant, for example.

You can also use it to enhance the effectiveness of your shampoo and to clean your hair brushes or other makeup brushes. This powder is in particular a softener, but also a fungicide.

It is perfectly possible to use it in combination with other ingredients for home maintenance, food or cosmetics.  The castor oil and baking soda mixture is very interesting and useful!

The castor oil and baking soda mix creates a blend for healthy, supple and nourished skin.

The cleansing properties of sodium bicarbonate make it possible to prepare an area to be treated with castor oil.

Bicarbonate and Castor Oil Poultice

The bicarbonate is used in this case before and after application of the castor oil.

For this recipe, mix bicarbonate and water and carefully clean the area you want to treat. Then heat your castor oil and soak a compress or gauze in it to soak it completely.

Apply this dressing on your skin, taking care to check the temperature of the bandage. Cover it with an adhesive film and place a bottle of hot water, a hot-water bottle or other on it. Wrap everything in a towel and let it sit for an hour. Then rinse with bicarbonate mixed with water again.

This method can be used for:

  • cuts
  • burns
  • bruises
  • twisted ankles
  • stretch marks
  • brown spots, moles, warts

Dr. William A. Mcgarey assures that a mixture of castor oil and bicarbonate would be very interesting to treat skin cancer. However, given the lack of scientific studies on this subject, it is better to remain cautious about this.

At the same time, it is quite possible to mix the two ingredients to treat warts. The combined ricinoleic acid and bicarbonate will attack the wart and dry it to make it disappear. Some also use this mixture on moles they wish to remove naturally.

Final Thoughts: Castor Oil and Baking Soda

Used either alone or in combination, these two products have excellent virtues. Don’t you agree? Do not hesitate to always have castor oil in your closet but also baking soda! This castor oil and baking soda mixture is therefore a combination tested and approved in my book! 🙂

    • Hey Joey – castor oil and baking soda work very well together but for aging, you can stick with castor oil, vitamin E, coconut oil, almond oil works great and black seed oil ! Check my castor oil for wrinkles post.

    I was wondering how much of castor oil and baling soda you would mix togethet for rubbing on the soles of your feet at night. Thank you kindly

    • Hey Tammy! It depends on what kind of texture you would like. A little bit of castor oil goes a long way, so I don’t think you would need more than a teaspoon. Start with a teaspoon each and mix until you get the desired texture. You can add coconut oil to help spread the castor oil easier, since it’s quite thick. Hope you find the combo that works for you! xo

    Hi there, I just tried baking soda and castor oil, I made it like a paste, then apply it to my face. How many times do I have to use this remedy? Thank you for all your info.

    February 28, 2018
    • Hi Lorna, thanks for your question! How was the paste? What are your expectations/goals for using this mixture? If it’s to treat acne, or just soften up your skin, the amount of times you apply it per week can vary from once per week, up to four or five times a week. All depends on your desired results 🙂

    hello! how do I store the mixture? Is it recommended or just mix it upon usage? thank you for your informative article!

    February 24, 2018
    • Hi there, many thanks for your question! It would be better to just mix the baking soda + water and heat up your castor oil whenever you’re ready to use it. It’s quick to make so using the ingredients fresh will be better in my opinion 🙂 Thanks again!

    Hii, can i use this mix for underarms and knees to lighten them?
    Or could you suggest me a remedy to lighten underarms and knees?
    Your reply is much awaited.
    Thank You

    February 21, 2018
    • Hi Bushra, great question! I’ve not researched about this yet, but from what I know, baking soda would possibly be a good mix with lemon juice and used as a lightener for dark underarms. Castor oil is effective for dark eye circles and scars, so I’m confident you could use a mix of castor oil + baking soda + lemon to use as a natural skin lightener, for underarms or knees. I’ll try to write about this soon in a future article. Thanks for your question and good luck 🙂
