Horseradish has a long history of use as a diuretic, and is also seen as a potently warming herb with traditional uses in helping with feverish chills, encouraging a sluggish circulation, and relieving many muscle and joint problems.
Crushing fresh horseradish root triggers a chemical reaction producing a compound called allyl isothiocyanate, which is mainly responsible for its characteristic hot, pungent character and taste.
Traditional culinary use of horseradish with roast beef may support its proposed actions in helping digestion by stimulating the production of gastric juices and enhancing appetite.
It has also been used as an ingredient in remedies for upper respiratory conditions for decongesting and clearing excessive catarrh and assisting with cough.
Caution: Avoid in pregnancy and with thyroid problems. Use cautiously in gastric irritation and peptic ulceration. Prolonged skin contact may cause irritation and sometimes blistering.

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.
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.
