To soothe and get rid of a sore throat using lemon oil just take 2 drops of lemon oil and add it to either some warm water or some warm tea.
And then mix the lemon oil into the warm water or tea by stirring it in.
Then just drink the tea or water and the lemon oil in the tea or water will soothe your sore throat.
You can also if you want to just inhale the lemon oil directly from the bottle but drinking the lemon oil works much better.
Another option is to put the lemon oil into a diffuser and breath the lemon oil in through the air.
