Lemon Essential Oil
The virtues of the lemon and its close relative, the citron, have been well-known throughout history. The poet Virgil had this to say:
And dulling tastes of happy Citron fruit,
Than which, no helpe more present can be had,
If any time stepmothers worse than brute
have poyson'd pots, and mingled herbs of sute
With hurtfull charmes: this Citron fruit doth chase
Blacke venome from the body in every place.
