About Olive Oil

Olive oil is one of the oldest known foods, with origins that date back to 3000 B.C. The mighty olive was a source of food, fuel, and medicine for the ancients in the regions known as present-day Crete and Syria.

Olive oil boasts an extensive list of health benefits, and is the prized feature of the Mediterranean Diet, a heart-healthy diet that has earned much acclaim around the world. When consumed as a food, olive oil has an array of health benefits, from preventing certain diseases to treating inflammation.

The Mediterranean countries of Greece, Italy, and Spain consume up to two-thirds of all olive oil that is produced worldwide, and the Mediterranean region is also known for having lower rates of cardiovascular disease and certain cancers.

Castor Oil and Olive Oil: The Break Down

Olive oil and castor oil provide a lot of the same health benefits. Your unique needs might mean that one oil will work better for you than the other. When it comes down to it, which oil is the better option for you?

Hair and Skin

We know by now that castor oil has a great reputation for thickening and regrowing hair. It turns out, so does olive oil! Olive oil can help remove the buildup of sebum–which is what prevents the growth of new hair follicles.

Olive oil is also rich in vitamins A and E, as well as antioxidants, which helps protect hair and seal in moisture. It can be used as a conditioner and you can even smooth a small amount of it over fly-away hairs when styling.

It is those same vitamins that make olive oil great for skin as well. Olive oil can moisturize, exfoliate, and improve elasticity of skin. It can also be used to gently and naturally remove eye makeup without the harsh chemicals typically found in over-the-counter eye makeup removers. Beware, olive oil can leave a greasy residue.

General Use

Castor oil is a diverse oil but is best used externally, on the contrary, olive oil’s list of internal benefits is quite long. Castor oil can treat gastrointestinal distress, can lengthen and strengthen hair, and can act as an antibacterial and antifungal for a multitude of skin issues. But, olive oil can be used to prevent and help with certain cancers, to polish household surfaces, and has even been used as a biodiesel fuel. Both oils have so many benefits, but olive oil has a little bit more character and a little bit wider of a reach.


Neither castor oil nor olive oil has a particularly satisfying smell, though the scent of olive oil is much more mild compared to castor oil, which some people find to have an offensive smell. The good news is, adding aromatic essential oils is always an option to improve the scent of any oil. Try adding lavender to castor oil, or lemon to olive oil.


Olive oil is bottled and sold at a variety of price points. Olive oil is commonly sold as extra virgin olive oil (EVOO), virgin olive oil, refined olive oil, or pure olive oil. Experts recommend cold-pressed EVOO for its purity and nutrient density. Olive oil can also spoil when exposed to light and heat, and the dark bottles help protect from oxidation. Olive oil should always be stored in a cool, dark place. You can expect to pay anywhere from $13 USD all the way up to $30 USD for a quality bottle of cold-pressed EVOO–sometimes even more.
