Tea Tree Oil Dosage and Dilution Ratios

What is the correct tea tree oil dosage to use for the various skin infections?

Using the correct strength of tea tree oil is important for two reasons.

A solution that is too strong can cause severe irritation when applied to different parts of the body.

A solution that is too weak may not be as effective and it just won't cure the problem. Just as important is how long you need to use this essential oil.

How long it would take to get rid of the problem would depend on the type of infections. For example, toenail fungus needs at least six months for a cure.

And even then, only one out of five people would have a complete cure. (Yes, toenail fungus is a very difficult condition to cure!)

Tea Tree Oil Dilution Ratios and Guidelines - How to Dilute It

tea tree oil glass bottle imageDo not use this oil full strength in the mouth (as a mouth rinse) or in the vagina. It is likely to cause significant discomfort and pain.

Moreover, at the full 100% strength, it may cause toxicity.

Tea tree oil can be dilute with distilled, filtered water or with oil or aloe vera gel. In addition, you can mix it into most creams or gels.

Always test the mixture on a small area of the skin first to check for any possible skin reactions.

Tea Tree Oil Dilution Ratios

1 part 1 part 50%
1 part 9 parts 10%
1 part 19 parts 5%

Tea Tree Oil for Acne

We do not recommend using this oil full strength on the face as the skin is thin and very sensitive. It may cause skin irritation and discomfort. Moreover, it is an oil and may aggravate the acne condition further, especially if you have oily skin.

Dilute it to 5 to 15% before using. Higher concentrations may be used but be on the lookout for side effects.

See Acne Treatment with Tea Tree Oil for a detailed discussion of this specific use.

Tea Tree Oil for Warts

Apply the oil full strength on the warts three or four times a day.

Using the full 100% concentration will ensure the most rapid cure.

If this concentration causes irritation or discomfort, use a 75% strength solution instead. However, the effectiveness is probably reduced significantly with a dilute solution.

Cover the wart with a bandage if necessary to avoid accidentally touching it. This is an optional step but it will allow the tea tree oil to stay on the wart longer before being rubbed off.

Keep in mind that warts are difficult to get rid of so the higher the concentration used, the greatly the chance of getting rid of it.

See Wart Treatment with Natural Remedies for a list of additional herbs and supplements that have been suggested by experts.

Tea Tree Oil for Thrush (Yeast infection in the mouth)

Dilute the oil to 5% or less and use as a mouth rinse four times daily. This can form a part of your daily oral hygiene routine.

The tea tree oil may be diluted with regular mouthwash or with water. Do not swallow the solution.

If irritation inside of the mouth develop, you will need to discontinue using it.

Tea Tree Oil Dosage for Athlete's Foot

Use a 50% strength of tea tree oil and apply the liquid to the infected areas with a cotton-tip or cotton ball.

Do this twice daily for maximum results. You can expect a cure in 4 weeks in about 60% of the people who used this method.

Applying tea tree oil to severe athlete's foot fungus may cause pain and discomfort due to the cracks in the skin. To avoid the discomfort, you may have to dilute the tea tree oil down further.

This may reduce the effectiveness. This would mean that treatment with tea tree oil will need to be used longer to ensure a complete cure.

See Foot Fungus Cure with Tea Tree Oil to get the complete details.

Tea Tree Oil for Yeast Infection (Vaginal Douche Formula)

Studies show that this essential oil can kill off candida albicans which is responsible for vaginal yeast infections.

Use a dilute solution of about 0.4% first and adjust upwards. Mix 0.4 mL of concentrated tea tree oil with 100 mL of either water or a prepared douche solution.

Concentration as high as 40% have been suggested. Use this concentrated dose only under medical supervision. Dosage this high is likely to lead to significant side effects such as discomfort and irritation.

For those individuals planning to make this, measure the amount of tea tree oil accurately by using a dropper calibrated in milliliters (mL). See the article Tips on Converting Drops to mL to get tips on the simple conversion process.

You can probably get several free oral dosing syringes from the pharmacy free of charge. These come in very handy for accurate measurements of small amounts of tea tree oil.

Also the report Yeast Infection Treatment with Natural Remedies lists several additional herbs and supplements that others have used to get rid of candida infections.

Toenail Fungus Infection

Apply 100% pure tea tree oil twice daily on the infected toenails. About one out of five people can expect a complete cure in 6 months.

However, do keep in mind that toenail infections are the most difficult form of fungal infection to get rid of. It is likely to take up to a year for a complete cure in many individuals.

And it is possible that this treatment may need to be used in conjunction with a prescription anti-fungal medication to result in a complete cure.

Tea Tree Oil Dosage for Cold Sores (Herpes Labialis)

Using a 6% tea tree oil gel on the cold sores as soon as they appear speeds the healing process. You can make this gel by mixing 1 mL of tea tree oil with about 16 grams of a lip balm gel.

See Herpes Treatment with Tea Tree Oil for complete details along with an in-depth discussion.

Scabies Treatment

Apply a 5% solution to the skin and leave on for 3 hours. Then wash off. Anecdotal reports suggest that it may work.

Tea Tree Oil for BV (Bacterial Vaginosis)

Some alternative health experts have suggested using a 200 mg tea tree oil vaginal suppository daily for 5 days. Some pharmacies specializing in compounding suppositories may be able to make this formulation for you.

However, keep in mind that BV is an infection that needs to be diagnosed and treated by your family doctor. Self-treatment is not recommended.

Does Tea Tree Oil Kill Bed Bugs?

Concentrated tea tree oil is shown to kill bed bugs.

However, diluting it may make it less effective. Spraying concentrated tea tree oil on to bed sheets and then sleeping on top of it can be irritating to the skin. Moreover, the tea tree oil is likely to stain the bed sheets. Avoid this.

Anecdotal reports suggest making a 5% to 20% tea tree oil in water solution, spraying it on the bed sheets and using a hair dryer to blow dry the sheets. (This seems like a bit of work.)

Others have suggested putting the bed sheets in the dryer for 20 minutes in the high heat setting. This will kill the bed bugs. This is a better choice and is less messy.

We would not suggest using even dilute tea tree oil solution on bed linens.

Tea Tree Oil for Skin and Nasal Infections

A 10% tea tree oil formulation has been shown to be effective for resolving MRSA skin infections.

Apply a cream formulation twice daily or even three times a day. Make this cream by mixing 10 mL of tea tree oil with 100 grams of cream.

Most creams may be used as a base. Aqueous cream or Glaxal Base would make a good base for diluting the tea tree oil.

This formulation may be applied into the nasal cavity to help with MRSA infections in the nasal passageways. The suggested base to use for applying to the inside of the nose is aloe vera gel or a commercially available nasal gel such as Secaris or Rhinaris nasal gel.

However, because the nasal tissue is a mucous membrane, it may be irritated by even a 10% tea tree oil gel. Always test a small amount first before using larger quantities in the nostrils.

If irritation develops, discontinue use immediately and irritate the nasal passage way with commercially prepared nasal irrigation solution.

Bottom Line

Tea tree oil has a long history of use and is shown to be effective for many types of infections.

Many people keep a bottle in their first aid cabinet to be used as an all-purpose antiseptic liquid.

Research studies suggest that it is effective in killing many types of bacteria, viruses and fungus.

Concentrated tea tree oil can be irritating to skin so dilution is recommended. ALWAYS test the formulation on a small area first.

Make sure you know exactly how to dilute tea tree oil properly to get the correct concentration.
