Why does St Johns Wort not seem to work for people?
St Johns Wort does work for people who have mild to moderate
depression. In fact, it works similarly to pharmaceutical drugs,
though it might take longer for it to work. It is not recommended
that St. Johns Wort be taken with prescription drugs that are meant
to deal with depression.
Since it is a herb, it is best to check the quality before
buying it. Generally, the better quality will be more expensive,
but it likely will contain more of the ingredient that is
needed.
