I regularly make a comfrey salve using dehydrated homegrown leaves and
roots steeped in extra virgin olive oil.
Even though the infused oil is very green, when it is melted with the wax, it always produces a lovely golden coloured salve.
I use a one part wax to four parts oil which is firm enough to scrape with the back of a fingernail and still soften in the warmth of my hands.
The wax comes from friends' hives and I render it myself.
I've also infused lavender, calendula leaves, plantain and yarrow for salves but comfrey is my favourite.
