How to use comfrey leaves to make a medicinal infused oil for sprains, bruises, and healing minor wounds. You begin by steeping dried comfrey leaves in a carrier oil then strain it out after
Although you can sometimes purchase herb-infused oils, they're actually very easy to make yourself. This is a folk-method of making comfrey-infused oil and its strength will vary depending on a number of factors. The time of year it is, when the plant material was picked, at what life-stage the leaves and plant are, how the leaves were dried, and how old the herbs and oil are.
If you grow or can forage comfrey yourself, pick the leaves when they're at their best on a bright, dry morning. Leaves should be young and lush and it's best to pick them before the plant flowers.
Dry the comfrey leaves completely. The stems are fleshy and wet so begin by pulling the leaves off and drying on a screen or in a food dehydrator. Alternatively, you can use needle and thread to string the leaves up like medicinal bunting. Air drying takes up to a week.
Make the Infused Oil
To start the comfrey0infused oil, fill a jar half to 2/3 full with dried* comfrey leaves. Tear or shred them to increase the surface area.
Fill the rest of the jar with a liquid oil of your choice, such as olive oil or sweet almond oil**.
Wait a minute or so, and top up the jars with more oil if the level goes down. Make sure that the herbs are completely submerged.
Place the jar(s) in a dark place for four to six weeks. Give the jar a shake every week or so or whenever you remember.
After the time has passed, strain the leaves out of the oil by pouring it through a cheesecloth-lined sieve/strainer. Capture the oil in a bowl below, and wring as much oil out of the cheesecloth as possible. The comfrey-infused oil will be a deep golden color.
Discard the comfrey leaf and store the infused oil in a jar in a dark, room-temperature place. You can use the same jar used for infusing or specialist dark jars that herbalists use****.
The oil has a shelf-life of one year or the best-by date of the original bottle of oil you used. Whichever is closer.
Notes
* It is best to use dried herbs when making infused oils. The tiniest amount of water from fresh leaves creates a habitat for microbes to grow, and it can also cause oils to go rancid quicker than they usually would.** Other good choices are cold-pressed sunflower oil, rice bran oil, apricot kernel oil, and grapeseed oil. **** Dark jars come in brown and blue and protect the oil from UV light. Light causes oils to oxidize and go rancid.
