The castor oil plant is one of the most fascinating gifts that Mother Nature has offered us so far. Extracted from castor beans, this oil has so much utility, it’s used across multiple industries. Yet these same magical beans contain ricin, a toxin that could be deadly. Deadly toxins in such a healthy and useful plant? How does that even work?

What Is Castor Oil?

Where does castor oil come from? Derived from castor beans that grow on a plant called Palma Christi usually found in the tropics, castor oil is nothing else but vegetable oil. Castor oil can be either transparent or have a yellowish color. It has a very specific odor, so if you’ve smelled it once, it’s easy to recognize it again.

The use of castor oil dates back as far as ancient Egyptian time and is still used today. It is a very popular ingredient in the cosmetics and medicine industries, but also has multiple other uses that we’ll go over in the following paragraphs. Despite the fact that castor oil is very versatile and has great utility, castor beans where it is extracted from contains ricin, which is extremely toxic. So, next question, what is castor oil good for?

Castor Oil Uses in Medicine

Is castor oil safe? In medicine, castor oil is known for bringing quite a number of ayurveda/holistic medicinal and nutritional benefits: from its antimicrobial and antioxidant properties to its capacity of healing wounds, muscle aches, and constipation. And since there are next to no castor oil side effects, it’s recommended by professionals. But some people still wonder how to use castor oil.

Immune System

Consumption of castor oil has frequently been tested orally for its ability to improve blood flow, lymphatic drainage, and other immune system functions. The Journal of Naturopathic Medicine has published a study in this regard. The results showed that subject with castor oil packs applied on their skin has experienced an increase in lymphocytes production.

Since castor oil may help with lymphocytes production, it can also help improve the digestive system, meaning it could aid with other problems, such as constipation.

Blood Circulation

There is a strong link between a person’s blood flow and the health of the lymphatic system. Problems with the latter can surely lead to issues with the former. The body’s lymphatic circulatory system needs a healthy cardiovascular system in order to make sure that there are balanced levels of lymphatic fluid and blood in your organs.

Skin Health

The pure form of the oil has magnificent antibacterial properties.  In fact, there is a lot of resemblance between the benefits of coconut oil and that of castor. Aside from being a great moisturizer, castor oil also has anti-inflammatory properties, especially when used with a cold compress.  Since castor oil doesn’t have any synthetic chemicals but is very rich in fatty acids, it can help with problems such as dry or irritated skin by keeping it moisturized at optimal levels daily.

Furthermore, this oil is known for being able to aid in healing wounds because it is efficient against different forms of bacteria. Staphylococcus aureus is one of the types of bacteria that are quite difficult to get rid of and is known for its potential of causing severe skin infections.

Labor Induction

For a very long time, it has been used to help pregnant women induce labor.  Because it’s edible, women that have reached their full pregnancy term would take a teaspoon of castor oil to induce frequent uterus contractions.

Note: Pregnant women who plan to use this oil should consult their doctor first!

This particular oil contains ricinoleic acid, which can activate certain receptors in the uterus.  Even if this practice isn’t medically approved, it is considered to be safe as a method of labor induction.  However, it may induce a feeling of nausea.


There are a lot of people that use castor oil supplements to treat arthritis pain.  Because of its anti-inflammatory properties, castor oil is frequently used as a massage oil, applied on swollen joints, aching muscles, and tissue.

Different observational studies have revealed the fact that ricinoleic acid applied topically can act as an analgesic and has anti-inflammatory effects.  Another study has examined the effects of pills, capsules, and tablets containing castor oil on knee osteoarthritis. By taking three capsules of this particular oil every day, over a duration of four weeks, patients have shown just as much improvement as those that have taken the conventional treatment.

It is recommended to massage areas with castor oil and then you apply hot water packs to make sure that the body fully absorbs the oil.

Natural Sleep Aid

Yes, castor oil is a natural sleep aid, a perfect solution for people who are having trouble falling asleep and getting some proper rest. Just place a tiny amount of castor oil on the eyelids, but make sure that you have at least eight free hours to get your beauty sleep. If you have to wake up in five or six hours, you will feel groggy.

Baby Colics

If you’re a parent, you are most likely with this medical mystery that is a baby’s colics period. It’s true that the exact triggers of colics remain unknown, but what if there was a way to tone down your baby’s suffering with a natural and completely safe remedy?

You can apply this particular oil to the baby’s belly, and then massage it with gentle circular movements. While this has not been medically tested, it is believed that the oil’s analgesic properties are the ones that soothe the baby’s pain.

However, always keep in mind that skin irritations are sometimes a side effect of the oil, so if you want to use it, test it on a very small portion of the skin to make sure the baby isn’t allergic to it.

TIP: If you want to create a castor oil pack, take a clean piece of wool, cotton, or flannel, dip it in castor oil and let it absorb the liquid a bit, and then put it on the affected area. Those of you who want to reuse that pack can place it in a ziplock bag.

How to Grow the Plants

Castor oil is made from the beans produced by the plant with the same name. As we all know by now, it has many important uses, especially in the cosmetic and pharmaceutical industry. Also known as “ricinus communis”, the castor oil plant is considered to be really dangerous, and it might not be a good idea to grow it if you have any children or pets. But if you do decide to take on this challenge, here is what you should know:

  • It generally takes about three months for a castor oil plant to grow. That’s because it’s a plant native to the tropics. This also means that it needs a lot of light and warmth to thrive, somewhere in between 77 to 86 degrees Fahrenheit.
  • You will need to plant castor beans in order to start growing your plant. Make sure that there are at least three feet of distance in between the seeds.
  • The soil has to be moist at all times. It also helps to add rotted compost to the planting hole, which should be about one inch deep.
  • If you live in an apartment and want to grow this plant inside a pot, you will need a large container, filled with potting mix.
  • For a plant to grow successfully, you will need soil rich with organic substances. Keep the soil moist but avoid over-watering, making sure that the soil is well-drained.
  • Even if you keep the plant in the sun, it’s important to avoid strong winds. The plant grows quite high and could easily break.
  • All-purpose fertilizer added to the soil once a month is more than enough to keep the plant well-fed. When you notice the first buds, place an inch of compost or manure at the plant’s base.
  • Castor oil plants do not require pruning.
  • The plant is also pretty strong against diseases and pests.
  • When the plant is ready for harvesting, you can collect the bean pods from the plant. When they’re ready, they will start drying. Make sure that you wear garden gloves and long sleeves.

When deciding to grow your plant, remember that ricin is toxic and that’s present in both the beans and the leaves of the plants, and your children and pets could be exposed to it. The plant can also trigger allergic reactions in some people.
