Chop together a good handful of comfrey leaves, Lemon balm, and Plantain leaves, a weed which grows almost everywhere, (plantain pictured below for identification)
Put in a enamel or stainless pot, and just cover with spring water and simmer for 30mins. Strain and squeeze liquid from leaves, measure liquid and add exactly the same amount of good oil, almond or olive will do. Put back on heat and simmer till it stops bubbling, no bubbles is a sign that the water has evaporated. Add small peices of beeswax, about a 50p peice at a time, testing each time using the cold plate test as for jam setting . When it sets straight away, pour into jars, put on lid and label. It will slowly set from the bottom up. Keeps for around a year in a cool place.
