What is the immune system?

The immune system is our body’s natural defence system against harmful microorganisms, pathogens, viruses, and other diseases.

It is made up of a complex system of cells that constantly track unknown visitors to the body, ensuring they do not cause us harm or weaken our functioning.

If something harmful is detected, the immune system will automatically react to try and clear the damaging organism from our bodies.

While our immune systems are largely effective, they tend to weaken as we grow older and thus make us more susceptible to frequent illnesses. They can also take a hit during the colder months of the year.

To keep our bodies in proper working order, we must ensure that our immune systems are well looked after and in perfect balance.

Which essential oils can help your immune system?

While all essential oils play a role in the general maintenance of our bodies, certain oils in particular can be extremely efficient towards ensuring the best for our wellness.
