Liquorice Root (Glycyrrhiza glabra) is often prescribed for tired people. It is popular because it creates a quick surge of energy. Dr Bieler used to say, “Beware anything that gives you energy quickly, because it is not supporting your glands, it is whipping them.” After just a few weeks your glands (especially the adrenals) become so enervated that they can’t function properly and you are much worse off than before. Liquorice does this, as do so many other ‘quick energy’ herbs and concoctions. This applies to the hyped ‘miracle’ pills, many of which contain contaminants.
