Cosmetic, medicinal, or industrial castor oil - what should you look out for?

Although castor oil is mainly known for its cosmetic use, it is also used for certain medical conditions, and for some industrial applications. Here we will tell you in detail about the different uses of this versatile oil.

Cosmetic castor oil. Castor oil has multiple benefits for the skin, nails and hair, so its main use is cosmetic. It is used as a facial moisturiser and anti-acne moisturiser, to stimulate hair growth and nourish hair, to reduce stretch marks and scars, etc.

Castor oil medicinal use. Although the medicinal properties of this oil are not as well known as the cosmetic ones, castor oil also serves as a natural laxative, and is anti-inflammatory, antibacterial, antiviral, and analgesic. It also improves the immune and lymphatic systems.

Industrial castor oil. This use may be the least known of the three, as few people are aware of castor oil's application in the automotive industry, through the manufacture of lubricants and hydraulic brake fluids. It is also used in the manufacture of paints, varnishes, enamels, inks and resins.

Moreover, castor oil has been shown to have chemical properties that allow it to replace traditional fuels, and even surpass them in effectiveness and performance. It also reduces gas emissions, and the processes for obtaining and refining it are simple.

Buying criteria

In this last section we will tell you what are the main purchasing criteria to select the most suitable massage oils for you, as there are certain important aspects to take into account when buying these products.


Although the main form of administration of castor oil is through facial, body and capillary massages, it is also used orally for certain types of pathologies or physical discomfort. Here are the recommended doses:

It is necessary to consult a professional beforehand

It is worth warning first of all that these recommended doses serve as a reference, as they may vary according to weight, sex, etc. For this reason, you should first consult a suitable professional who will prescribe the castor oil according to your own needs.

Bottles of castor oil solution, used mainly as a laxative, analgesic and anti-inflammatory, usually come in 70 ml bottles. The recommended oral doses for adults are 15 to 60 ml per day, and for children over 2 years of age 5 to 15 ml per day.

Use is contraindicated in pregnancy and lactation

For best results, it is recommended to be taken on an empty stomach with juices or other beverages that quench the oily taste of the oil. It is contraindicated for use in pregnancy and breastfeeding, as it may abruptly induce labour, or be harmful to the baby when ingested through breast milk.

Castor oil usually comes in 20 ml to 500 ml containers, depending on the type of use. For industrial use, they are obviously larger sizes. It is important to buy a container according to the frequency of use, as it can lose its properties over time.


To make the most of the benefits of castor oil, it is important that it retains as much of its natural properties as possible. For this reason, we will comment on the characteristics that this oil must have to maintain its quality:

Virgin. Virgin oil is oil that has not undergone chemical processes or refinement, so it retains its natural properties and nutrients intact. On the product label it may also appear as "pure" or "crude" oil, which is ultimately the same as virgin.

Cold-pressed. Cold-pressed oil has the particularity that its seeds were extracted from the original plant, without being subjected to chemicals or heat. The heating of the seeds causes it to mix with the product and lose some of its natural purity.

Organic. Organic oil is undoubtedly the purest and most natural, but there are often brands that sell "organic" products at higher prices, which in reality do not comply with the corresponding quality; for this reason it is necessary to verify that an "organic certificate" appears on the label.

Hexane-free. Hexane is a petroleum-based chemical used in the manufacturing process of many industrial foods. Hexane can be harmful to health and detracts from the natural purity of castor oil.

Glass bottle. The glass bottle, besides being more hygienic and environmentally friendly, preserves the natural properties of the castor oil better. It is advisable to keep it in a cool, dark place so that it does not lose its beneficial nutrients.


Although castor oil does not usually present side effects that imply a major health hazard, in some cases it can cause adverse reactions of minor or major consideration according to each case and specific pathology:

Induction of labour. Castor oil is contraindicated for pregnant women, as it can induce labour. It is also not recommended during breastfeeding, as it may be harmful for the baby to ingest it through breast milk.

Allergy. The topical use of castor oil may cause allergy in some people, so it is advisable to apply a small amount on the skin to test the body's reaction, or avoid its use if you suffer from severe allergies.

Diarrhoea. Although castor oil is used for constipation, overdosing can cause diarrhoea, leading to general dehydration in some cases. It is important to pay attention to the dosages given on product labels, or consult a doctor.


Although castor bean can be deadly because of its toxic proteins, during the oil extraction process these harmful components are denatured by heating, dissolving any toxic substances that may be stored in the seeds.

Castor oil is therefore completely safe, as long as the appropriate doses are respected in relation to age, sex and clinical condition, and it is not given to pregnant women or people with allergies without prior consultation with a specialised professional.

Other uses

As we have mentioned throughout the article, castor oil is mainly used to nourish, moisturise and restore dermal and capillary tissues, as a natural laxative, and as a refined industrial oil. But it also has other lesser-known uses, which we will mention below:

It fights mouth fungus. Thanks to its antibacterial and antifungal properties, castor oil is very beneficial in combating the "candidaalbicans" fungus, which causes gum infections, and other dental problems such as plaque overgrowth.

Mosquito repellent. Castor oil is an excellent natural mosquito repellent, which can be homemade by mixing it with a few drops of cinnamon, lemon, eucalyptus or citronella oil to enhance its results. An excellent option for not using chemical products.

Relieves arthritis. Castor oil is very effective in relieving muscle pain caused by arthritis or osteoarthritis. It should be applied directly to the skin, previously heated, with a damp cloth. There are also analgesic creams that contain castor oil among their ingredients.

Eliminates corns. Castor oil is a very good natural option for removing calluses from the skin. You should apply a dressing or bandage with this oil on the hardened area and leave it overnight so that it softens and falls off by itself the next morning.

Removes moles. The procedure is the same as with corns: place a dressing or bandage with castor oil on the mole (this time mixed with baking soda) and leave it on. The mole will fall off on its own, but it may take several applications for this to happen.
