Maurice,

The PA's are naturally present in the pollen. The fireweed plant
"creates" it. Just as these alkaloids are in plants such as comfrey
(mostly in the roots) and cause the same type of damage if ingested.
This is not a foreign "agent" that is sticking to the pollen. Fireweedi
is present in large numbers in other areas and the honey is sold - a
recent post on another group said it was very light in color and flavor.

Thank you for that information, but you did not mentioned what is the source
of this agent and how it got to the vegetation.
Dr. Mohsen M. Ramadan, can you give us that information if you can ?

Thank you,

Maurice
