This herb has a long tradition as an effective tissue healer. One of comfrey's common names is ‘Knitbone’ which gives us a clue as to what was one of these traditional uses. The allantoin that it contains has been shown to stimulate the cells responsible for collagen, cartilage and bone formation. As use of comfrey may accelerate the healing process, its use on open wounds should be avoided in case it causes the wound to heal from the top down, thereby trapping any infection inside. Historically it would also have been used to treat digestive problems such as gastric ulcers and colitis, but as comfrey contains ingredients that are thought to be harmful to the liver, it is no longer used as an internal medicine.
Caution: External use only. Do not apply to open wounds.

At Jekka’s we sell herbs in 1 Ltr and 2 Ltr pots. These are established and hardy herb plants that are grown following organic principals and to survive the UK climate. Please read Jekka's blog that contains her top steps to growing on your herbs.
There is also ‘Jekka’s Seasonal Tips’ series that covers growing and maintaining herbs in early spring, late spring, summer and autumn & winter. Together they form Jekka’s guide on how to grow herbs. For a hands-on herb experience, where you will learn how to grow herbs, check out our Master Classes.
Our herbs are designed to be grown in containers or planted in the garden. Although some herbs will be quite happy indoors, most prefer being outside. Please see our indoor growing blog for more information.
If you require pots or compost, we have developed Jekka's Herb Kits, which includes Jekka's "Grow On" Kit. These kits contain all you need to grow on your herbs.
If you think your herbs need a little more attention we always recommend an environmentally friendly solution, and these are Jekka's top three:
- Maxicrop liquid seaweed: 'Feed on Fridays' as Jekka always says for all round good plant health.
- SB Invigorator: a safe and effective insecticide and fungicide to help control a wide range of pest species
- Epsom salts: the horticultural equivalent of what you put in your bath that will top up the plant's magnesium and stop orange leaves.
Please note, the compost in Jekka's Kits will have enough natural food for approximately 6 weeks.
For more information on growing herbs plants please see Jekkapedia, Jekka's blog or our FAQs page.
One of our three core roots is that we are Environmentally Conscious and for the past 30 years all the herbs grown at Jekka’s have been raised following sustainable, environmentally friendly and organic approaches resulting in a remarkable biodiversity at the herb farm.
Our herb seeds are also untreated and can be used to grow organic herb plants. Our seeds are hand packed into gassine bags, which are fully recyclable, compostable and biodegradable. These bags are then put into beautifully illustrated paper seed packets. Therefore, our environmental footprint is small.
