Experience giving a plant infusion to a cat? (carqueja)

[NadiaRey]

I'm trying to determine if I can give my cat carqueja tea (Baccharis trimera). It's a medicinal plant that was extremely effective to cure my own stomach ulcer. My cat Gremlin has felt bad for days and I was thinking it might be something similar.

However, as you can imagine, I have to check first if there's any risk in giving cat this particular plant. And the problem is, I have been looking in the internet but I haven't yet found information on carqueja and felines. (I only know it's not recommended if a human taking it has low blood pressure, is hypertensive or diabetic.)

So I come to you to see if any of you has heard about or has any experience with a cat drinking/eating this plant. And maybe if you have an alternative. Thanks in advance.

This is a question for your vet to answer. If your vet doesn't know if this tea is safe, then err on the side of caution and do not give any to your cat.

My cat Gremlin has felt bad for days and I was thinking it might be something similar.

What are your cat's symptoms? All sorts of things can cause a cat to not feel well so you can't make an assumption that it's stomach ulcers and the tea will help. A trip to the vet would be best to determine why your cat is not feeling well and to get the proper medications if those are needed.

Sorry, just to clear out, yes I'm visiting my vet for weeks now. I had an appointment with a nutricionist vet to revise his diet and one with a vet cardiologist, both last week. The head vet the week before, and now I'm waiting for another appointment (she will be writing to me tomorrow). I also got him a abdominal ultrasound before that, and blood panel. Probably will be doing him X-rays soon too. They are in the loop.

Additional information: My cat Gremlin is FIV+.

The stomach ulcer... to be honest, I was thinking to give it to him as preventive. Because the whole point is that it's really not clear what he has.
So I wouldn't call it an assumption. I'm trying to beat whatever is hurting Gremlin to it. And hopefully help him while we are still looking for the source. (Besides, you can understand, with a FIV+ cat, whatever the root is, I need to squash it fast. Before it becomes a bigger problem, if possible.) Of course, that's so long as it's safe. If I don't find someone who can tell me "I gave carqueja to my cat and it's safe", I'll not attempt to give him any.

That's why I'm asking, just in case there's someone here who knows. Previously, my oldest, Sueño, passed from cancer and, in both cases, I used and was recommended plant-based infusions. And a lot of those did help, so I was hoping to repeat the experience. That's all. For example, Juniper is a safe alternative for cats, I just learned.
Also I should mention, obviously, none of the specialist mentioned before had knowledge of carqueja in particular. (It's not a very common subject either so I'm not expecting them to know, honestly.)

To answer the other thing:

As for the symptoms: His front legs kind of wooble in place when he's sitting or standing.
Also, he walks a bit funny. Like, he crosses his legs suddenly while walking, as if maybe nearly falling, but not quite.

Just to give context: He used to fall down a lot when he was first diagnosed FIV a little over two years ago. Specially his rear: he tumbled down from there first.
Right now he doesn't fall, and he's able to jump pretty well. That's the baffling part.
He doesn't look dizzy either (compared to how it was before, that I just mentioned).
But he's hiding more. Usually under my bed. Last few days, he wouldn't purr when petted (he's an extremely prone to purr guy) when in that space.
And he goes from ravage-hungry (his usual), to not finishing his plate in the same day, or even the spawn of a few hours.

My bet is he's in some kind of pain, but it's coming and going, not constant.

Digestive system is a likely culprit because of the inconsistency in symptoms.
I've also been looking into muscular, vesicular, neurological or bones problems. So far nothing quite fits his thing?
Of course you are welcome to share your thoughts.
