Which of the following describes a practical precaution when using Melaleuca alternifolia (Tea Tree) oil on the skin?

Tea tree oil is a potent essential oil, and applying it directly to the skin can irritate or sensitize even when the skin seems normal. The practical precaution is to dilute it in a carrierOil or lotion before topical use. Dilution reduces the concentration of the active constituents that contact the skin, lowering the risk of irritation, redness, or dermatitis, especially on sensitive or reactive skin. A patch test on a small area first helps ensure there’s no adverse reaction. In general, avoid undiluted use on the skin, and don’t use tea tree oil on broken skin or mucous membranes; never ingest it.
