Borage has a long traditional use for treating fevers, catarrh, lung problems and as a tonic in nervous exhaustion and as a diuretic.
The seeds contain an oil rich in fatty acids and have been used to help with menopause, premenstrual symptoms and in inflammatory conditions such as arthritis. This oil has not been found to contain any the ingredients thought to be harmful to the liver.
Caution: Recent studies have raised concerns that borage leaves contain chemicals which may cause serious liver damage. For this reason, home use is not recommended and some herbalists now avoid or restrict internal medicinal use of this herb.

Growing indoors? Check out Jekka's blog on indoor herb gardening for some advice.
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.
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 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 to top up magnesium and stop orange leaves.
Please note, the compost in Jekka's Kits will have enough natural food for approximately 6 weeks.
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.
