I would do some research on this. From what I understand, ivermectin comes from a micro-organism found in soil and wormwood (artimisia) is a plant. Both are anti parasitic but I do not believe they are the same thing.
Here is a link to an article about Ivermecting and also provides other natural alternatives, wormwood being one of them:

I was here early in 2021, then got "spooked". I am back because I want to live. I read a lot. I observe. I listen. I have faith in us.
I do not know anything about sweet wormwood, but I found an interesting reference if people want to investigate. It is from a book called "Dumas on Food: Recipes and Anecdotes from the Classic Grand Dictionnaire de Cuisine." On p. 39 is an entry called Absinth (or Wormwood) / Absinthe. The entry describes the use of the "green muse" by poets and soldiers and how it contributed to many deaths. Again, I am not sure if the two are connected, but I read the reference a while back and set it aside because it was interesting given the discussion of wormwood I have seen here previously. It mentions two types (Roman and Pontic or little absinth).
