One clarification about photosensitivity and St John's wort and cows:
this info comes from practical experience rather than from experiments.
SJW has been reduces to 1% of it's original population in the NW of the US
by ranchers who consider it a dangerous weed based on sun reactions in
cattle who eat large amounts of the wild plant.  Photoreactions are rare
but known in humans, too, particularly fair skinned people.  This
photoreaction seems important for it's experimental use in HIV.  Just
wanted to clarify an issue raised in a message today.
