6 Ways Castor Oil May Benefit Your Health

Have you ever heard of Castor oil? Maybe your grandparents used it or you read about it in a book, but have you ever considered what it might be for? Castor oil has been used for centuries for its numerous health benefits. These benefits are often spoken anecdotally, but is there actually evidence to back them up? This is what we know about castor oil, its benefits, and whether or not you should consider adding it to your health and wellness repertoire.  

What is Castor Oil?

Castor oil is a pale yellow vegetable oil that is extracted from castor seeds. It is derived from the seeds of the castor plant (Ricinus communis) and is known for its healing and immune-supporting properties. It is rich in fatty acids and contains a unique compound called ricinoleic acid, which is responsible for many of its therapeutic properties. Castor oil is used in various beauty and healthcare products and is also ingested for its health benefits.

Benefits of Castor Oil

Take a quick search around the internet and you’ll likely discover a wide array of bloggers and influencers talking about castor oil. Among the countless purported benefits, however, it’s important to understand them more thoroughly and how effective they really are. This is what science says about castor oil and its benefits.

1. Wound Healing

Many claim that castor oil has remarkable wound-healing properties. It can help indirectly support the immune system by speeding up the healing process. Its deep penetration into the skin ensures it reaches the affected area, and helps to keep tissues moist to promote an optimal healing environment. However, it should be noted that when castor oil is used in a clinical setting, it is usually part of a formulation containing other ingredients. One such formation is Venelex, an ointment containing both castor oil, trypsin, and Balsam of Peru, an extract derived from the Myroxylon balsamum tree. They usually contain other ingredients along with it. So, while the oil itself may be beneficial for wound healing, it is not necessarily acting on its own. Consult with your healthcare practitioner before using castor oil on open wounds.

2. Anti-inflammatory Effects

Castor oil possesses potent anti-inflammatory properties. It can help reduce inflammation in the body, providing relief from conditions such as arthritis, muscle pain, and joint inflammation. Applying castor oil topically on the affected area can help alleviate pain and swelling.

3. Antifungal, Antibacterial, and Antiviral Properties

The antimicrobial and antiviral properties of castor oil make it an effective remedy against fungal and bacterial infections. It can inhibit the growth of harmful microorganisms and help prevent skin infections such as athlete’s foot and ringworm. Applying castor oil to the affected area may help clear the infection and promote faster healing.

4. Moisturizing and Nourishing

Castor oil is an excellent moisturizer that can keep the skin soft, supple, and hydrated. It penetrates deeply into the skin, providing nourishment and preventing moisture loss. Regularly applying castor oil can improve the overall health and appearance of the skin, making it smooth and radiant. Do be aware, however, that some people can have an allergic reaction. Apply to a small patch of skin first to test before applying it to a large area.

5. Hair Growth

Owing to its high content of ricinoleic acid, castor oil is purported as a remedy for hair growth. It nourishes the hair follicles, stimulates blood circulation in the scalp, and potentially promotes hair growth. Applying castor oil to the scalp and massaging it gently can strengthen the hair roots, prevent hair loss, and encourage the growth of thick and healthy hair. Even with high praise and anecdotal claims, there is no scientific evidence to support castor oil for hair growth.

6. Powerful Laxative

Castor oil has been used as a natural remedy for digestive issues like constipation. It acts as a mild laxative, helping to relieve constipation by stimulating bowel movement. However, it is important to use castor oil for this purpose sparingly and as directed by a healthcare professional. While it has been approved for use by the FDA, usage for this purpose has decreased over the years. This is because other constipation solutions have been found that tend to cause fewer side effects.


While castor oil offers numerous benefits, it is important to use it with caution. Some people may be allergic to castor oil, so a patch test is recommended before applying it to the skin or scalp. Consuming castor oil internally should be done under the guidance of a healthcare professional, as excessive consumption can lead to gastrointestinal discomfort and diarrhea. Pregnant women and individuals with certain medical conditions should avoid using castor oil without consulting their healthcare provider.

The Bottom Line

Castor oil is a versatile and beneficial natural remedy that can speed up healing and support immunity. From wound healing and immune support to anti-inflammatory and moisturizing effects, castor oil offers a wide range of health benefits. However, it is important to use it responsibly, follow precautions, and consult a healthcare professional if needed. Incorporating castor oil into your healthcare routine can be a natural and effective way to boost your health and well-being.
