Hot infused oil
Put the oil and the herb in a glass bowl over a pan of boiling water or in a double saucepan and heat gently (covered) for about three hours.
Pour the mixture into a jelly bag or muslin bag fitted securely to the rim of a winepress and strain into a jug, pressing carefully all the liquid out of the herb.
Pour the infused oil into a clean, dark glass bottle, using a funnel if necessary. Seal and label each bottle. Store in a cool dark place.
Note
This can be done without a winepress though the yield won’t be as efficient. If you haven’t muslin or a jelly bag a white cotton pillowcase will do (but it won’t be white after the process!)
Comfrey - Symphytum officinale
Also known as Lus na gCnámh Briste, Knitbone, Boneset, Bruisewort. The botanical name symphytum is derived from the Greek sympho (to unite). All the names are a reminder of its traditional use in healing fractures and sprains.
Comfrey is found on moist banks, field borders and ditches all over the coutryside. When the plant is just beginning to grow in early spring and has not flowered be sure you know the difference from the leaves of the foxglove (the leaves of which are poisonous!). The comfrey leaf has stiff hairs on its surface compared to the smoother leaves of foxglove.
