I see two major problems here concerning the gross misunderstanding of herbalism.
1)In reference to the article, there is a world of difference between evidence-based medical herbalism and anecdotal home remedies. Neither the author nor the person quoted appear to know the difference.
2)Hemlock is not an herb, it is a poisonous plant. There is a clear and discernible difference between the two. They can not be compared. There are two reasons a person might ingest hemlock: sheer ignorance or a desire to die.
This sort of uninformed and irrational commentary is fear-mongering and slander.
