Essential oils have been around for thousands of years. Using them for therapeutic or medicinal reasons is called aromatherapy. Here’s what you need to know.
What Are Essential Oils?
They’re the scented parts of a plant, usually the bark, leaves, or peel. You smell them when the plant is crushed. Special steaming processes also bring out the fragrance.
Essential oils have a strong scent. But that’s not what helps you feel better. The plant’s chemicals affect your brain and body. They get into your bloodstream when you put the oil on your skin or breathe it in.
Types of Essential Oils
There are lots of them. But there’s some scientific evidence that certain oils might help ease knee and joint pain. They include:
Do They Really Work?
Black cumin. Older people rubbed black cumin oil into their achy knees 3 times a day for 3 weeks. They felt better than the group that only took acetaminophen.
Ginger. A group of people with ongoing knee problems reported less pain and stiffness a month after a massage with ginger oil. The group that only got a massage did not. They also showed better physical function overall.
Lemongrass. A small group of people with rheumatoid arthritis felt a little less pain after using lemongrass oil for 30 days. Experts think the plant chemical citral may be anti-inflammatory.
How to Use Essential Oils
Don’t put essential oil directly on your body. It may sting or irritate your skin. Here are some tips:
- Massage. Put 10-15 drops of an essential oil in 1 ounce (2 tablespoons) of a carrier oil. Those are oils like coconut, almond, olive, avocado, or jojoba. That’ll help protect your skin and make it easier to absorb. Rub into your skin, wherever you feel joint pain. You can also massage some onto your feet, arms, wrists, neck, or behind your ears.
- Inhaling. You can put a few drops on a cloth or sniff the air as you slowly wave an open bottle of essential oil in front of you. You can also buy a waterless or water-based diffuser. That’s a device that sprays essential oil mist into the air. Follow the instructions on how much to use.
Always test a small part of your skin first. Be on the lookout for an allergic reaction. Symptoms may include:
What Not to Do
Aromatherapy is generally considered safe. But since it is not regulated, you can't be sure what you are getting. All of the ingredients do not have to be listed on the label. If you’re pregnant, don’t use essential oils unless your doctor says it’s OK. Don’t use them on children or babies.
Don’t eat or drink them. Experts aren’t sure it’s safe. And be careful if you go outside. Some essential oils, like bergamot, can make your skin sensitive to sunlight.
