Is there a natural herb that , when taken, makes a person ill if they drink alcohol?

A supplement called piracetam is used in some countries to treat alcoholism because people who use it report their desire for alcohol drastically decreases. You can buy it on the net. I know you were looking for something natural and this is man made, but they say it does not have toxic or addictive tendancies.

As an herbalist working on my Master's in the field I can say, without a doubt, No. Tgere is no herb that will do that.

yea, natures already figured this one out.

its called self-control.
