Tea tree essential oil is distilled from _Melaleuca alternifolia_. Its distinctive
aroma and use in topical products make it a familiar botanical ingredient. Familiarity
does not make concentrated oil a universal remedy or an appropriate product for 
every member of the family.

## What the evidence can support

[NCCIH’s tea tree oil resource](https://www.nccih.nih.gov/health/tea-tree-oil) describes
limited evidence for certain topical applications and the need for further research.
Findings from a studied formulation do not establish that neat essential oil or 
a homemade blend produces the same result.

The previous article promised broad healing, stronger hair and protection from airborne
viruses. Those claims were not supported by relevant evidence for the recommended
uses and have been removed.

## Diffusing is a fragrance choice

Adding tea tree oil to a diffuser should not be presented as a way to purify the
air, prevent infection or protect a household through winter. A pleasant or strong
scent is not a measure of disinfection.

If using a diffuser, check the device and oil instructions for suitability, ventilate
the room and stop if anyone develops symptoms. Do not assume a particular drop count
is suitable for every room or household. Read [the diffuser selection and safety guide](https://aunaturalorganics.com/essential-oils-diffusing/)
before use.

## Choose the exact product carefully

Consult the [Tea Tree ingredient entry](https://aunaturalorganics.com/ingredient/tea-tree/)
and the product label. Check the botanical, composition, lot information, intended
route of use and directions. “Lemon tea tree” refers to a different ingredient; 
its name is not a reason to substitute it into a routine designed for _Melaleuca
alternifolia_.

Do not swallow tea tree oil. It can cause serious harm when ingested. Topical products
can also cause irritation, and natural or organic wording does not guarantee tolerance.

## Keep cosmetic use separate from medical care

For skin or scalp symptoms, choose care based on the diagnosis rather than a general
claim of antibacterial activity. Do not use concentrated essential oil on wounds,
near the eyes or as a replacement for prescribed treatment. Follow assessed product
directions instead of adding an unspecified number of drops to skincare.

Store the bottle as directed, away from children and pets. Compare labeled ingredients
in the [Ingredient Library](https://aunaturalorganics.com/ingredients/), and ask
the supplier when the intended use or safety information is unclear.
