Essential Oil Dilution Calculator — Safe Dilution Ratios for Every Use

🚨 Critical Safety Disclaimers:

1. Not Medical Advice: Essential oil dilution guidelines are based on NAHA and Robert Tisserand safety standards. This tool is for educational reference only and does not replace consultation with a certified aromatherapist or medical professional.

2. Patch Test Mandatory: Always perform a 24-hour patch test on the inner forearm before full application, even at recommended dilutions. Apply a small amount, cover with a bandage, and check for redness, itching, or irritation after 24 hours.

3. Pregnancy: Many essential oils are contraindicated during pregnancy, especially in the first trimester. The oils listed as safe are based on general guidelines — always consult your gynaecologist or a certified aromatherapist before use during pregnancy.

4. Children: Children require significantly lower dilutions. Many oils safe for adults are NOT safe for children. Avoid eucalyptus, peppermint, rosemary, and clove near children under 10. Never apply essential oils near a child's face.

5. Photosensitivity: Citrus oils (lemon, bergamot, lime, grapefruit) cause photosensitivity. Do not apply to skin exposed to sunlight within 12–24 hours. Use steam-distilled or furocoumarin-free (FCF) versions for daytime use.

6. Sensitisation Risk: Repeated use of the same essential oil can cause sensitisation (allergic reaction) over time. Rotate oils and take breaks. Once sensitised to an oil, the reaction is permanent.

7. Epilepsy: Avoid rosemary, eucalyptus, camphor, and spike lavender if you have epilepsy or seizure disorders.

8. Pets: Many essential oils are toxic to cats, dogs, and birds. Never apply essential oil products to pets without veterinary guidance.
