What makes the warming and 'easier breathing' feeling happen? Is it safe for children?

The warming sensation and the feeling of easier breathing are sensory effects created primarily by the eucalyptus oil in the balm. When applied to the skin, eucalyptus oil produces a characteristic cooling-warming sensation and releases a strong herbal vapour as it evaporates. This aromatic experience is what many people associate with a clearer feeling in stuffy seasonal periods. It's important to understand this is a sensory and aromatic effect, not a medical treatment for any condition.

Regarding safety, products containing essential oils like eucalyptus are not suitable for infants or children under 3 years of age. For older children, it may be suitable if they tolerate essential oils well, but it's crucial to supervise use, ensure they don't get it near their face, and consider a patch test first due to the potential for skin irritation from eucalyptus oil and natural limonene. The balm should only be used on intact skin and kept away from the eyes and mouth for all users.
