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:

Perhaps the Sweet Wormwood uptakes the soil bacteria, and converts it to some other substance, that is in the leaves. Which, in turn, provides healing benefits. God's Grace, many Prayers, and Ivermection saved my life from the brink of death from Covid-19/Pneumonia, a bit over 2 years ago!!
A team of researchers that includes Worcester Polytechnic Institute Biology Professor Pamela Weathers has found that extracts from the leaves of the Artemisia annua plant, a medicinal herb also known as sweet wormwood, inhibit the replication of the SARS-CoV-2 virus and two of its recent variants.

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).
