Question about Olive leaf extract

Few days ago I started taking olive leaf extract, mainly as fungus prevention. However, when I take it I feel strong vertigo for a few hours. Is that herx? Or just the sign it is not suitable for me? Am I doing a harm to my body? Should I discontinue its usage?
It is severe vertigo, I need to lie down and to wait it to go away.

Have you tried reducing the dose?

If it continues, I would find something else to take for the prevention.

Does it happen immediately? I've never used olive leaf but I would be concerned about an allergic reaction. I have dealt with vertigo as herx but it was always hours after using the herbs.

Perhaps someone with experience will be along that can answer your question. You could also research the forum for vertigo by entering Lyme-herx from olive leaf in the search button under the join healing well at the top of the page.

Personally, I would try something else because vertigo is tough to deal with.
