Can you prevent UTI after sex with Tea tree oil?

Are you having urinary tract infection (UTI) outbreaks after sex? I personally use a Tea tree oil wash to prevent UTI and believe that among other things it kept me UTI free for years.

Tea tree oil (TTO) is known for it’s antibacterial and antimicrobial qualities and is made out of leaves and twigs of an Australian tree called Melaleuca alternifolia. There are hundreds of ways Tea tree oil could be used for health reasons, including battling E. coli to prevent UTI.

Benefits of Tea tree oil for UTI prevention

Tea tree oil could be used as a potent antimicrobial in various forms and shapes: suppositories, wash, wipes, sprays.

With that in mind, here are words of caution:

  • Tea tree oil might cause allergic reactions.
  • Never use undiluted Tea tree oil anywhere on your skin.
  • TTO could also be toxic if swallowed, so keep away from children.
  • Make sure you are not allergic to TTO. If unsure, use a patch test to determine your sensitivity. You can try a bit of the wash on your wrist to make sure that it is not going to cause any itchiness or irritation. To test, apply some on your inner wrist and leave for 24 hours.

Tea tree oil intimate wash recipe

We already discussed that there are plenty of E. coli bacteria living inside of you. It doesn’t take much for pathogenic bacteria to travel up to your vagina, and hang out there ” until the moment is right”.

Next thing you know, during sex some of the sneaky E. coli will get into your urethra (aka “pee-hole”). Tea tree oil could help prevent UTIs by washing away whatever bacteria it encounters.

Personally, I make a “super strong” Tea tree oil intimate wash. For many, it might feel too strong, so perhaps you can use a lesser amount of Tea tree oil.

Also, I’m not a chemist or a doctor, so take it with a grain of salt and it’s always better to consult with a licensed OBGYN, of course.

This is how I make it. I take:

  1. A plastic bottle to use as a dispenser
  2. Tea Tree Essential Oil – You can buy it at Trader Joe’s or Amazon.
  3. Two tablespoons of liquid shower gel

I mix together two tablespoons of liquid shower gel, one teaspoon of Tea tree oil and a full cup of water and pour it all into the bottle. I shake it and mix it well before each use.

I use the mixture as a genital wash after sex and make sure to rinse it well (I do not use it for douching, which I never do, to begin with). The slight tingling sensation for me is normal, but burning and irritation that doesn’t go away is not, and might indicate an allergic reaction.

These statements have not been evaluated by FDA. As you might know, cosmetic products are not intended to be used for disease treatment or prevention.

The resulting mixture will have a very strong concentration of Tea tree oil. It is important that you make sure that you are not allergic to it first.

If you decide to prepare this mixture for yourself, please make sure you are not allergic to Tea tree oil first.

  1. Hi Anastasia,
    With this mixture can I use a cotton ball to pat on/around the urethra and leave it like that or should I pour it on the area, leave it for a few minutes and rinse it off with water? Thank you

    • Hi Lee, I would advise against leaving this mixture on. I use it as a regular intimate wash, meaning rinsing with water right away.

  2. Hi,

    I have been having recurring UTIs for 3.5 years, I am 27. All kinds of tests, related to kidneys or bladder, did not show any abnormalities.
    However, the urodynamics showed pelvic floor dysfunction- pelvic floor muscles tightness.
    The non-proved hypothesis was that since these muscles control the bladder emptying process, so if they are tight, the bladder could not be able to contract properly and this may bring to some amount of urea remaining constantly in a bladder. And this, in turn, may serve as a favorable environment for E.coli to grow.
    After a few months of physical therapy, the muscles have been back to normal tightness. I have been taking D-mannose for half a year during that treatment+Physical therapy period. Everything seemed to be ok, but recently (after half a year after therapy was done) I have again started having UTI. I have not checked the status of the pelvic floor muscles yet, to see if it’s indeed connected to UTI, but has anyone ever heard of pelvic floor dysfunction as a reason for UTI?
    Alternatively, I feel that mostly UTIs are back 1-2 days after intercourse, so I am thinking of taking D-mannose constantly and what else would be the best way to avoid UTI after sex if your body has a predisposition to it, as unfortunately, the UTIs have become chronical.. 🙁
    I am married, and we don’t have a baby yet, and I have no idea how can I plan on having one with this problem…

  3. Can’t you just mix coconut oil and tea tree essential oil and dip a q-tip in the mix and apply to urethra? Maybe insert a wee bit into the urethra so it reaches inside?

    • Hello!
      I would not recommend inserting Tea tree oil in urethra 🙂
      The idea is to wash the outsides so the bacteria that are “in transit” have less chance to reach urethra after sex. I would recommend taking D-Mannose after sex if your UTIs are caused by E.coli.

  4. Hi Anastasia
    I’m wondering if soap / tea tree oil will kill the good vaginal bacteria as well? (sort of what antibiotics do to the good bacteria in our gut…)
    But then washing with only water after intercourse won’t really do much to the bad bacteria… so what would be the best way to go about it? confused =/
    Please share your thoughts!

    • Good question! Studies suggest that Tea tree oil (TTO) has strong antimicrobial properties, at the same time TTO “is useful in removing transient skin flora while suppressing but maintaining resident flora”. In a study reviewing efficacy of Tea tree oil against microorganisms causing BV they found that that “all lactobacilli tested were appreciably more resistant to tea tree oil than organisms known to be associated with BV”.
      Bottom line, Tea tree oil is “friendlier” with your good bacteria than it is with pathogenic microorganisms regardless where you use it: vaginally or on the skin. Make sure to be very careful and never use undiluted TTO on your skin.
      Best wishes,

  5. Hi there I had uti for about ten years was tired of taking expensive antibiotics plus my baby bag has gone weak now then now after every sex I use tea tree with olive oil mixed n apply inside vagina it will burn 1min woowww after tat does the job m now free from uti and yeast infections

    • Dora, thank you for sharing your experience! Super happy to hear you found a natural solution for your troubles! Ten years is a long time…
      How much tea tree oil do you normally use?

  6. I learned that unilke other drug store medicines, Cystex helps to relieve the pain and burning associated with a urinary tract infection (UTI) while also inhibiting the progression of the infection with an antibacterial.
