Hello,
One OTC supplement which studies have proven helps with alcohol withdrawal is Dihydromyricetin.
This
study states:
Dihydromyricetin (DHM; 1 mg/kg, i.p. injection), a flavonoid component of herbal medicines, counteracted acute alcohol (EtOH) intoxication, and also withdrawal signs in rats including tolerance, increased anxiety, and seizure susceptibility
From the reading I've done, abusing alcohol for long periods of time changes your brain's "GABA System". Then, when your brain is deprived of alcohol, your GABA System won't function properly. This leads to anxiety and in extreme cases seizures.
Dihydromyricetin helps your GABA System function properly while you are going through alcohol withdrawal.
This is the
article I read about it.
