The Magical Herb Called Eucalyptus


You’ve probably come across a range of products containing eucalyptus, not to mention the infamous eucalyptus oil. So, this is pretty much a herb a lot of us are familiar with. But just how much do you know about this famous herb?

Eucalyptus globulus a.k.a  Blue Gum is the main source of eucalyptus oil used all over the world. It was first cultivated in Australia and has over 400 different species. While it is not ingestible, the oil that comes from the eucalyptus tree features as antiseptic, a perfume, as a key ingredient in cosmetics, as a flavoring, in dental preparations, and in industrial solvents.

Eucalyptus is believed to have a number of medicinal properties, although not all of them have been confirmed by research. Here are just some of its magical benefits!

Dental Health

Eucalyptus contains antibacterial and antimicrobial properties, which is why it is commonly featured in some mouthwash and dental preparations.

Eucalyptus promotes dental health by repelling bacteria that causes tooth decay and halitosis. Since eucalyptus promotes periodontal health, it accounts for why its extract is found in some chewing gums.

Colds and Respiratory Problems


Eucalyptus has been found to be one of the most effective remedies against some respiratory conditions such as chronic obstructive pulmonary disease (COPD), asthma, bronchitis, sinusitis, the common cold, cough or the flu. Eucalyptus also features in a range of concoctions believed to relieve symptoms of the common cold, for example, cough lozenges and inhalants.

Its essential oil improves many respiratory conditions by stimulating the immune system, and provides antioxidant protection. Thus, improving your respiratory system.

In medieval times,  eucalyptus was used to treat fungal infections and skin wounds due to its antiseptic and anti microbial properties. It was observed that it helped disinfect wounds and sped up the healing process.
