While a very few essential oils, such as lavender and tea tree are safe to apply directly to the skin, most are so concentrated that they must be diluted with 'carrier oils'. Carrier oils are massage oils typically made from nuts and seeds.
Some people may have allergic like reactions, just as some people are allergic to grass or pollen. Kobashi or Elixirhealth.co.uk can not be held responsible for any adverse reactions from their use. If you are prone to skin sensitivity and allergic reactions dilute oils to 1% or less and make sure to patch test on your skin. If in doubt of the amount for you personally, please get professional advice.
Used responsibly the oils are a safe natural product.
** Please note: The published origins of the essential oils may differ with what's advertised, in line with sourcing, availability and market forces.
