Also true with foods. In some cases it is about rate-limiting

enzymes. i.e. The ALA in flax seed gets converted to EPA and DHA

with a few tablespoons, but if one uses large amounts little or no

EPA and DHA is produced. (D-6-desaturase is needed twice in pathway)

 

Although a loose example does anyone know the biochem mechanisms that

might cause the opposite effect with herbs?

 

 

(As an aside can I gently suggest that if folks start a new thread

from a " Digest " email that the subject is changed to something

meaningful? Glancing down my subject list of " Digest Number #### " is

dubious. I guess that is up to Todd. I went ahead and changed this

subject heading.)
