Uses of Castor Oil and Baking Soda

Do you know natural home remedies prepared at home can treat moles and wart? Learn more about the uses of castor oil and baking soda to make your home remedies.

Hello 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 very interesting: uses of 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 it.

Since castor oil is somewhat 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 areas prone to dryness, such as the hands and the feet.

To mix, you can opt for jojoba oil, olive oil, or coconut oil. The last one is an unusual remedy. By mixing half of any of the above oils with half of the castor oil and letting it soak all night, it can be an excellent remedy to treat dry or curly hair.

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 useful base in home cosmetics. Natural and economical, you probably know baking soda in the form of a white powder.

It is used primarily for home care products such as cosmetics, food, gardening, but also for healing (1).

Biodegradable, sodium bicarbonate, or sodium, does not have any harmful effects. It only has surprising virtues, and it is always good to have some at home. The baking soda castor oil benefits are great and help in a variety of ways.

It is truly a handy powder. Being effective against bad odors and sanitizing is just one of its many benefits. In cosmetics, baking soda is used, especially when brushing teeth and also a significant constituent in the composition of homemade deodorant.

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

Make up kit

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

Castor Oil and Baking Soda For Face

The castor oil and baking soda mix create 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 (2).

Bicarbonate and Castor Oil Poultice Recipe

The bicarbonate is used in this case before and after the 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 compressor gauze in it thoroughly.

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 container, or other on it. Wrap everything in a towel and let it sit for an hour. Then rinse with bicarbonate remixed with water.

  1. I have lot of moles in my face which has been lying there for ages (I’m 42 now). Will castor oil and baking soda help?

  2. 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

  3. 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.

    • 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 🙂

    • 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!

  4. 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?

    • 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 🙂
