The humble lemon is probably the most useful food to have in the house: powerful disinfectant, immune booster, grill-pan degreaser, throat gargle and even facial skin toner! It also adds loads of flavour and vitamins to almost any dish.

Cases of scurvy -- an extreme deficiency of vitamin C with one of the most visible symptoms being bleeding gums and loss of teeth -- are on the rise.

In England, there has been a 50pc increase in the last 10 years of children being admitted to hospital with it. As lemons are incredibly rich in vitamin C, they are the perfect preventative.

Alongside vitamin C, lemons are rich in citrus flavonoids which are phtyochemicals (biologically active plant compounds) that can assist the healing of wounds and strengthen the walls of blood capillaries.

Vitamin C helps fight infection, strengthen the immune system, make collagen (the main protein in connective tissue), keep the skin and joints healthy and protect against cell damage by free radicals.

It makes an excellent gargle for sore throats and can be used on any small wounds and abrasions as a natural antiseptic and wound healer.

When I feel a cold coming on, I get my big soup pot out, fill it with water and boil up three lemons (juice squeezed into the water) and the skins and one ginger root (roughly chopped) for 15 minutes.

I add Manuka honey to the slightly cooled lemon tea, and sip throughout the day.
