To fight pesky fungal infections in your nail beds, ragged cuticles and brittle nails, pour castor oil into a bowl with one-part Epsom salt and three-parts water. Soak for about 15 minutes. If you have the time, repeat this treatment daily. Castor oil’s anti-viral, anti-fungal, and anti-bacterial properties will help strengthen your nails, so you’ll be able to try the polish-free look in no time.
To treat smaller scars or blemishes, use a cotton ball and dab the oil directly onto the intended spot and leave it on for as long as possible — overnight, if you can. Be careful, because like olive oil, castor can leave annoying stains.
Castor oil can help heal your sunburn immediately by rubbing the oil directly on the burn. It has the same cooling sensation as aloe and its ricinoleic acid will protect any burn-induced blisters that pop from infection-causing bacteria and conquer inflammation!
