If you've ever used castor oil, you know that it can be a bit of a hassle. It's thick, sticky, and difficult to apply. But the benefits of this natural substance are said to be worth the trouble.

Castor oil is said to improve the appearance of hair, skin, and nails. It's also touted as a natural remedy for constipation, hemorrhoids, and colds. But does this multitasking oil have an expiration date? Read on to find out.

Regular castor oil has a shelf life of about one year, while cold-pressed castor oil can last up to five years. You can tell if your castor oil has gone bad if it has a rancid smell or if it has changed colors.

If you're not sure whether your castor oil is still good, it's best to err on the side of caution and throw it out. After all, you don't want to put something on your skin that might cause irritation or be ineffective.

If you're interested in trying castor oil, be sure to get cold-pressed castor oil. Not only does it have a longer shelf life, but it's also said to be more effective than regular castor oil.
