Natural ways to kill a cold

Before you reach for the Lemsip there are natural, and more effective ways to beat a cold, or, at least dramatically reduce the symptoms and shorten its duration to under 24 hours.

Vitamin C - does it work?

Vitamin C works but you have to take a lot – ideally 1 gram (that’s 20 oranges worth) an hour. I've done this for years and can usually knock a flu or cold on the head in 12 hours.

One study gave volunteers 8 grams on the first day of a cold and almost half, 46 per cent, were cold free the next day (1). In a study involving 700 students, those taking hourly doses of 1000mg of Vitamin C for the first 6 hours and then 1 gram three times daily thereafter, reported an 85% decrease in cold symptoms compared to those receiving conventional cold and flu treatment (2).

When people quote evidence saying that vitamin C doesn't work they are just talking about reviews of studies that used too low a dose. You have to have a high dose from the immediate impact of a virus. Then the results are impressive. I know because I've been doing this for 30 years and have almost never suffered for more than 24 hours.

THINK ZINC

The mineral zinc, in doses of 50–100mg a day, has also proved to be anti-viral (3). It is available in lozenges for coughs and colds. On a daily basis, as prevention, supplement 15mg a day. Supplementing this amount of zinc has been shown to make the body’s T-cells much more effective, hence boosting immunity (4). Some vitamin C tablets contain zinc, eg 3mg per tablet. If you take 10 to 20 tablets over 24 hours, at the onset of a cold you'll be getting effective amounts of zinc.

IMMUNE BOOSTING BERRIES

Especially immune-boosting are blue-red foods. Black elderberry, for example, stops viruses from penetrating cells and spreading their germs. In a double-blind controlled trial, elderberry extract given to those with flu, produced a significant improvement in symptoms – fever, cough, muscle pain – in 20 per cent of patients within 24 hours, and in a further 73 per cent of patients within 48 hours. After three days, 90 per cent had complete relief of their symptoms compared to another group on a placebo, who took at least six days to recover (5). In another double-blind controlled trial, black elderberry extract cut recovery time in those with influenza by four days (6).

The hero ingredient in blue-red foods is anthocyanidins (cyan means blue). For a virus to invade and infect cells it must release an enzyme called neuraminidase. The drug Tamiflu was a neuraminidase inhibitor. So is vitamin C. Anthocyanidins have a direct effect on inhibiting neuraminidase (7).

Most people think of blueberries but two of the richest sources of anthocyanidins are bilberries and cherries, and particularly Montmorency cherries. A single shot of CherryActive, a concentrate of pure Montmorency cherries, provides the same level of anthocyanidins as 180 blueberries. During an infection it’s worth having two or three shots a day, in a hot drink with pieces of fresh ginger, which soothes sore throats.

WHAT I TAKE

“At the first sign of a cold I take 3 grams of a souped up C formula containing zinc, black elderberry, zinc and ginger,  plus a shot of CherryActive, then 1 gram an hour, plus more CherryActive. Invariably I’m symptom free the next day.”
