When can tea tree oil help knee pain?

Tea tree oil is best known for its antibacterial and antiseptic activity, with current research backing this up. It can indeed kill certain types of bacteria. (1, 2)

This property can be extremely beneficial when an open wound causes septic arthritis. This type of joint inflammation happens because a bacteria or virus entered the joint through the injury, infecting the tissue. (3)

But using tea tree oil on the wound could help kill the bacteria and manage the infection. This in turn can reduce the pain derived from inflammation.

If you want to use tea tree oil to aid your knee pain, you can do so but topically. You should never ingest it – it’s poisonous.

With that said, here are some safe ways you can use tea tree oils to help your knee pain:

1) As a knee massage oil

It can be used to gently massage the affected area. But, don’t apply pure tea tree oil directly onto the skin, as it can cause irritation. Always dilute it with a carrier oil, such as:

  • Olive oil.
  • Lavender oil.
  • Coconut oil.
  • Almond oil.
  • Peppermint oil.
  • Ginger oil.

A good ratio is combining 15-20 drops of tea tree oil with 2 tablespoons of carrier oil. Pour this mixture into a dark bottle to preserve it.

Another option: CBD oil – you can use it directly on your knee!

2) In your bath

You can add a few drops of tea tree oil into a tub of warm water and soak your knees. This is a great way to alleviate knee pain derived from osteoarthritis or rheumatoid arthritis, as the heat itself will relax your tissues and promote relief.
