I beg to differ with you Jim. I feel that boosting your immune sytem over a long term just makes it weaker and dependent on the herbs. At least thats my take on it. Do consult a herbalist before taking Goldenseal, It has been banned in some states due to people overdosing on it. Yes herbs are powerful and not to be taken lightly.
I didn't know about Sambucol, I'll have to ask about it. If it is good I'll have to add it to my gear. Does it taste as vile as Echinacea? Nah it couldn't, nothing tastes worse...
