A recently published study confirms one of our oldest home remedies – garlic improves your immune response to colds and flus.
A long time ago, in my 20’s I lived in London and spent time travelling around Europe. I spent a day with a German woman in Spain, who at the time had a bad cold and ate several cloves of raw garlic between slices of bread. She told me it was a common remedy in Germany for colds. And my Scottish flatmate in London (room-mates for you in USA), used to boil up at least a dozen garlic bulbs and make a thick garlicky soup to treat her colds.
Aged garlic reduces cold and flu severity: RCT data
Supplements of an aged garlic extract may reduce the number of days a person suffers from cold and βflu by 61%, says data from a randomized, double-blind, placebo-controlled study.
Summary
Background & aims
Earlier studies show that dietary bioactive compounds can modify proliferation of Ξ³Ξ΄-T cells. Garlic contains numerous compounds that have this potential and, in addition, has been shown to influence NK cell function. Our primary aim was to demonstrate that aged garlic extract could modify these immune cells.
Methods
A randomized, double-blind, placebo-controlled parallel intervention study recruited 120 healthy subjects (60 per group) to determine the effect of aged garlic extract supplementation (2.56Β g/d) on immune cell proliferation and cold and flu symptoms.
Results
After 45Β d of consuming an encapsulated aged garlic extract, Ξ³Ξ΄-T cells (pΒ =Β 0.039, nΒ =Β 56) and NK cells (pΒ =Β 0.043, nΒ =Β 56) were shown to proliferate better compared to placebo. After 90Β d of supplementation, illness diary entries showed that the incidence of colds and flu, a secondary outcome, were not statistically different; however, the group consuming the aged garlic extract appeared to have reduced severity as noted by a reduction in the number of symptoms reported (21% fewer, pΒ <Β 0.001, z-test of proportions), a reduction in the number of days (61% fewer, pΒ <Β 0.001, z-test) and incidences (58%Β fewer pΒ <Β 0.001, z-test) where the subjects functioned sub-optimally and the number of work/school days missed due to illness (58% fewer, pΒ =Β 0.035, z-test).
Conclusions
These results suggest that supplementation of the diet with aged garlic extract may enhance immune cell function and that this may be responsible, in part, for reduced severity of colds and flu.

I will bet it also helps kill the spread of cold. Garlic breath ugh.
Bad breath jokes abound!
Well you can always take aged garlic extract, I haven’t noticed bad breath from that.
Yeah yeah…. But then you have epic bad breath! π
thats probably why it works in the first place – noone is coming near you, hence no germs and no flu π
but seriously – nice find
Dear Julianne,
This might be off topic, however, There is a your home solution for the everyday cold that is made up of eating a clove of garlic a day. I in reality don’t have an appetite, so producing a meal out of it will not likely operate. But I want to try out this out.
What can I dip this garlic clove in to make it extra nice?
I look forward to your next post
