Does Castor Oil Expire & How To Make It Last Longer?

What is Castor Oil, you may ask? It is a versatile vegetable oil extracted from the Ricinus Communis plant. The oil is obtained by pressing the seeds. The resulted oil contains ricin, which is a toxin. This substance is heated, and the damaging components are eliminated by high temperatures. Thus, castor oil is created.

Castor oil has been used since ancient times. Egyptians used to burn it in fuel lamps or apply it as a remedy for eye irritation. Nowadays, it is used in the beauty industry as skin and hair treatments, as a food additive, as a remedy for constipation, and it can even be found in biodiesel fuel. It has been proven to have anti-inflammatory, antimicrobial, and moisturizing properties.


Let’s start with the internal advantages of taking castor oil. It turns out that it is quite a powerful laxative. An important aspect is that it is a natural treatment. How does it work? It increases the intestinal muscle movements, accelerating the clearing of the bowels. Keep in mind that it should not be taken on a regular basis. Side effects are rarely reported, and they usually occurred when the tolerated dose was exceeded; however, nausea and abdominal cramps have been reported.


If you apply castor oil topically, you will notice that it is an amazing moisturizer rich in ricinoleic acid, which is a monounsaturated fatty acid. Triglycerides help retain moisture so that your skin will become more hydrated and start to glow.



Castor oil is the ideal solution if you are looking for something to cover your wound. This is because it has antibacterial properties, meaning that it acts as an antiseptic substance that prevents the development of infection. Moreover, this unique oil increases tissue growth; this means faster rejuvenation, with a lower risk of complications.


Despite its oily texture, it seems that ricinoleic acid is actually a very useful tool against acne. The reason is that it eliminates the bacteria which reside inside the pore and reduces the adjacent inflammation. Thus, it also soothes and reduces the redness in the afflicted area.


Candida is, unfortunately, quite a common pathogen. It is a fungus that can reside in the mouth, in the genital area or on the skin, and its distinctive aspect is that of milky white plaques. If a tooth is affected, it can lead to stomatitis. It has been shown that even patients with stomatitis benefited from castor oil by brushing their teeth with it two times a day. This is because castor oil is a renowned antifungal that inhibits Candida overgrowth.


This is quite a universal claim. However, it seems that it is backed up by a little evidence, and it is based more on the personal experience of various people. Some suggest that their hair grew five times faster after starting to use castor oil. If you want to try it for yourself, you can use it as a hair mask 2-3 times a month. You can do this by thoroughly applying it through your hair and wrapping it up with a towel or t-shirt for half an hour. Then, wash it as you usually would and be patient to see the results.


It is said that standard castor oil has a shelf life of one year, while cold-pressed castor oil can last up to five years. It is vital to know how to store it in order to preserve it for as long as you can. You need to keep it properly sealed at all times. The room temperature is equally important as it needs to be below 20 degrees Celsius. Otherwise, the oil will deteriorate much faster than its expiration date. Keep it away from moisture and direct sunlight. If you respect these conditions, you may be able to preserve the castor oil longer than the mentioned expiration date. You can check whether the oil is usable or not by checking its colour, smell, and consistency. A darker colour or a rotten smell means that the oil is compromised and should not be used.


All things considered, castor oil is a valuable natural resource that you can significantly benefit from internally and topically. Keep it in optimal conditions, and you will be able to keep your castor oil bottle usable for much longer.
