I've probably consumed 40 or 50 lbs of the stuff over the years. They are really good with walnuts and or pine nuts, and have certain...tonic properties. NB if you're thin and/or have cold hands/cold feet freqently they will probably taste great to you and they are probably really good for you. FROM A TONIC POINT OF VIEW if you're heavier, hot all the time, and you don't like their taste...perhaps they are not for you (not saying the phytochemicals would not be of benefit).
I think how we experience different foods is wary important and probably gives a clue to whether or not its good for us, in a way we miss this aspect with supplements and dried powders. A side from a basic nutritional need what is good for us probably depends on our individual physique. What seams to be positive in a short perspective is often weaken in the long run (like cocaine for instance). Cocaine is extreme but I believe this is a principal which probably is applicable to many supplements and herbs.
Or at least that’s how a practitioner of the chine’s medicine probably would view this. But on the other hand we are expose to so much toxics, heavy metals, chemicals, alkohol, etc any way so maybe it doesn’t have any relevance in the modern world; where one extreme have to be compensated witch an other.
