Using essential oils to treat bruises, bumps and haematomas is generally safe, but it is important to observe a few precautions and contraindications. Essential oils are powerful and must be diluted in a suitable carrier oil before application to the skin. It is essential to carry out a skin tolerance test by applying a small quantity of the mixture to a small area of the skin to check that there is no allergic reaction. This test should be carried out at least 48 hours before using on a larger area.
If in doubt, consult an aromatherapist or healthcare professional. What's more, certain essential oils are not recommended for pregnant women, young children, people with epilepsy or those suffering from certain medical conditions.
It is therefore essential to check the specific contraindications for each essential oil and take appropriate precautions according to the situation. If in doubt, it is always advisable to seek the advice of a healthcare professional or experienced aromatherapist.
