Ideal Applications
FEATURES
🌱 Certified Organic
100% pure organic Melaleuca alternifolia — no synthetic additives, fillers, or fragrance oils. Every bottle contains only steam-distilled tea tree leaf oil.
🇦🇺 Australian Origin
Sourced from certified organic tea tree plantations in Australia, where the plant is native. Australian tea tree oil is the global gold standard, with the highest terpinen-4-ol content and strictest quality standards (ISO 4730).
♨️ Steam Distilled
Gentle steam distillation from the leaves and terminal branchlets preserves the full spectrum of aromatic compounds, including the terpinen-4-ol that defines tea tree's character.
🔬 High Terpinen-4-ol
Contains 30–48% terpinen-4-ol, the compound primarily associated with tea tree's skin-care applications. Higher terpinen-4-ol content is generally associated with higher quality tea tree oil.
✨ Skincare Powerhouse
One of the most popular essential oils for blemish-prone skin. Commonly used in natural skincare routines to help maintain a clear, healthy-looking complexion. A staple ingredient in many facial cleansers and spot treatments.
💇 Scalp & Hair Care
Widely used in shampoos and scalp treatments. Research suggests tea tree oil may help support a clean, balanced scalp environment and improve the appearance of flaky scalp conditions.
🧹 Natural Household Cleaner
One of the most effective essential oils for natural cleaning. Tea tree's fresh, clean aroma and reputation for surface-cleaning make it a go-to for DIY household sprays.
🩹 First Aid Staple
Traditionally used in Australia as a first aid remedy for minor cuts and scrapes. Commonly included in natural first aid kits. Always dilute before applying to skin.
🫙 Dark Glass UV Protection
Packaged in dark amber glass to shield the oil from UV light, which accelerates oxidation. Oxidized tea tree oil is significantly more irritating to skin — proper storage matters.
🏭 Hand-Bottled in the USA
Every bottle is hand-filled and inspected at our US facility, lot-coded for traceability so each batch can be tracked back to its source.
DILUTION GUIDE
About This Oil
Tea tree (Melaleuca alternifolia) is a small tree native to Australia's New South Wales, where Aboriginal Australians have used the leaves for centuries. The essential oil is steam-distilled from the leaves and is characterized by its high terpinen-4-ol content. It is one of the most extensively researched essential oils and a mainstay of natural skincare, first aid, and household cleaning. Tea tree oil is non-phototoxic but carries a small risk of skin sensitization, particularly when the oil has oxidized — so proper storage and timely replacement are essential.
Safe Dilution Ratios (Max 2.5%)
Tea tree is generally well-tolerated at standard dilutions but can sensitize some skin types, especially when oxidized. Always use fresh oil and perform a patch test before first use.
Drop counts are approximate — actual drop size varies by dispenser.
| Application | Tea Tree Drops | Carrier Oil | Notes |
|---|---|---|---|
| Spot Treatment (Blemishes) | 1–2 drops | 1 tsp (5 ml) | ~1% — dab on individual blemishes with a cotton swab |
| Face & Neck | 5–6 drops | 1 tbsp (15 ml) | ~1% dilution — gentle for blemish-prone or oily skin |
| Body | 10–12 drops | 1 tbsp (15 ml) | 2–2.5% dilution (max safe concentration) |
| Scalp Treatment | 5–8 drops | 2 tbsp (30 ml) | Massage into scalp; leave 30 min, then shampoo |
| Foot Soak | 5–8 drops | 1 cup bath salts | Mix into salts, dissolve in warm water; soak 15–20 min |
| Diffuser | 3–5 drops | Water reservoir | No carrier needed; diffuse 30–40 min at a time |
Diffuser Ratios by Room Size
| Room Size | Tea Tree Drops | Duration |
|---|---|---|
| Small (bathroom, closet) | 2–3 drops | 20–30 minutes |
| Medium (bedroom, office) | 3–5 drops | 30–40 minutes |
| Large (living room, kitchen) | 5–7 drops | 40–60 minutes |
Always perform a patch test before first topical use: apply a diluted amount to the inner forearm and wait 24 hours before broader application.
HOW TO USE

SAFETY & HANDLING
Sensitization & Oxidation Risk
- Tea tree oil carries a small risk of skin sensitization in some individuals, even at recommended dilutions
- Oxidized tea tree oil is significantly more irritating — oxidation increases the concentration of sensitizing compounds (peroxides)
- Refrigerate after opening to significantly slow oxidation
- Replace within 1–2 years of opening — do not use old, oxidized oil on skin
- If the aroma becomes harsh, chemical, or significantly different, discontinue topical use (still usable for cleaning)
- Always perform a patch test before first use and before use after any storage gap
General Safety
- For external use only — do not ingest (tea tree oil is toxic if swallowed)
- Always dilute with a carrier oil before applying to skin
- Non-phototoxic — no UV restrictions after topical use
- Keep out of reach of children and pets
- Consult a healthcare provider before use if pregnant, nursing, taking medications, or have a medical condition
- Discontinue use if irritation occurs
Storage Guidelines
- Refrigerate after opening — this is especially important for tea tree due to its oxidation sensitivity
- Store with the cap tightly sealed to minimize air exposure
- Keep away from heat sources and direct sunlight
- The dark amber glass bottle protects against UV degradation
- Expected shelf life: 1–2 years when refrigerated after opening
- Tip: write the date you opened the bottle on the label so you can track freshness
First Aid
- Eye contact: Flush with carrier oil first, then rinse with clean water. Seek medical attention if irritation persists
- Skin irritation: Apply carrier oil to dilute, then wash with soap and water
- Ingestion: Tea tree oil is toxic if swallowed. Do not induce vomiting. Contact Poison Control (1-800-222-1222) immediately or seek emergency medical attention
- Allergic reaction: Discontinue use. Seek emergency attention if swelling, difficulty breathing, or severe rash develops

FREQUENTLY ASKED QUESTIONS
Is this tea tree oil organic?
Yes. Our tea tree essential oil is 100% pure, certified organic Melaleuca alternifolia from Australia. It contains no synthetic additives, fillers, fragrance oils, or carrier oils. It is steam-distilled from organically grown tea tree leaves and hand-bottled at our US facility.
What does tea tree essential oil smell like?
Tea tree has a fresh, herbaceous, slightly medicinal aroma — camphoraceous with a clean, sharp quality and subtle green undertones. It is sometimes described as a cleaner, greener eucalyptus. As a middle note, it provides body and longevity in blends.
Can I use tea tree oil for acne?
Tea tree oil is one of the most popular essential oils for blemish-prone skin. Research suggests it may help maintain a clearer complexion when used as part of a consistent skincare routine. Add 1–2 drops to 1 teaspoon of jojoba oil and apply to individual blemishes with a cotton swab, or add 2–3 drops to your regular facial cleanser.
How do I dilute tea tree essential oil for skin?
Tea tree has a maximum safe topical dilution of 2.5%. For spot treatment (blemishes), use 1–2 drops per teaspoon of carrier oil (~1%). For full-face use, use 5–6 drops per tablespoon (~1%). For body, use 10–12 drops per tablespoon (2–2.5%). Always perform a patch test, especially if you have sensitive skin.
Why does oxidized tea tree oil irritate skin?
As tea tree oil oxidizes (breaks down from exposure to air, heat, and light), it forms peroxides and other compounds that are significantly more irritating and sensitizing than fresh oil. This is why proper storage is critical — refrigerate after opening, keep the cap tightly sealed, and replace within 1–2 years. If the aroma changes noticeably, discontinue topical use (you can still use oxidized oil for cleaning).
Is tea tree essential oil phototoxic?
No. Tea tree oil is non-phototoxic, meaning you do not need to avoid sunlight after applying it to skin. It is safe for daytime topical use.
Can tea tree oil help with dandruff?
Tea tree is widely used in shampoos and scalp treatments for flaky scalp conditions. Research suggests it may help support a clean, balanced scalp environment. Add 5–8 drops to 2 tablespoons of carrier oil for a pre-wash scalp treatment, or add 3–5 drops directly to your shampoo bottle.
What carrier oils work best with tea tree?
For blemish-prone skin, jojoba oil is excellent — it is lightweight, non-comedogenic, and closely mimics the skin's natural sebum. Fractionated coconut oil works well for body application. For scalp treatments, coconut oil or jojoba are both popular choices. For foot soaks, use Epsom Salt as a carrier.
Is tea tree essential oil safe for pets?
Tea tree oil is toxic to cats and dogs if ingested or applied undiluted. Cats are particularly sensitive because they lack the liver enzymes to metabolize terpenes. Do not apply tea tree oil to pets. If diffusing, ensure the area is well-ventilated with an exit route for animals. Consult your veterinarian before using any essential oil around pets.
Can I use tea tree oil in the bath?
Due to tea tree's sensitization risk, we recommend using it primarily in foot soaks rather than full-body baths. If you do use it in a bath, mix 3–5 drops into 1–2 cups of bath salts before adding to water (never add undiluted oil directly to bathwater). Use fresh, non-oxidized oil only.
How many drops are in a 15 ml bottle?
Approximately 300 drops, using the standard euro dropper cap included with each bottle. Actual count varies slightly depending on oil viscosity and dispensing speed.
How should I store tea tree oil?
Refrigerate after opening — this is especially important for tea tree due to its oxidation sensitivity. Keep the cap tightly sealed to minimize air exposure. Expected shelf life is 1–2 years when refrigerated. If the aroma becomes harsh or significantly changes, discontinue topical use.
Can I ingest tea tree essential oil?
No — and this is especially important for tea tree. Tea tree oil is toxic if swallowed and can cause serious adverse effects including confusion, loss of coordination, and breathing difficulty. Our essential oils are formulated, tested, and labeled for external use only. If accidental ingestion occurs, contact Poison Control (1-800-222-1222) immediately.
