Depends, I purchase Frankincense and myrrh in oil form. If you purchase it in dried herb form, you can make oils by putting it in olive oil and making your own. I use oils and dilute in more oil or water.. We use Wormwood for parasites. I love the idea of the Rose petals…never heard of that either….For internal issues raw garlic is a good step in the right direction. I am cautious about internal EOs. Raw honey, and garlic will help weed out internal infections, ginger as well.
