I just purchased a bottle of Thayer's Lemon Witch Hazel, and I have heard that Adding essential oils to witch hazel like Eucalyptus, or peppermint, can give it an extra kick. I just found out we have bottle of each at my house so I was wondering who has done this, how effective it is, what is the proper ratio (how many drops per ounce), and do I just use one or both EO's?
